Home > Ovens & FurnacesIndustrial Furnaces > Vacuum & Atmosphere Endothermic Gas Generator A typical use would be in the case hardening of steel gears where the carbon content of the steel has to be tightly controlled. Endothermic generators built by Vacuum & Atmosphere are compact, air cooled, efficient and reliable producers of these atmospheres. An endothermic generator is comprised of a heavily insulated, heated chamber; a nickel catalyst filled retort; a feedstock gas metering system, a chamber heating system and an output gas cooling system. A precisely metered mixture of feedstock gas (usually natural gas,) and air is introduced into the catalyst filled retort where it is heated to approximately 1850 F. The mixture reacts with the catalyst which prompts the conversion of the feedstock gas and air to a process gas mixture of approximately 40% nitrogen, 38% hydrogen, 20% carbon monoxide and 2% carbon dioxide and methane. The input air/gas ratio can be adjusted, within limits from lean (more air) to rich (more feedstock), to vary the carbon potential or dew point making the output atmosphere useable for a wide range of heat treating requirements. Upon completion of the reaction process the endo-gas is cooled to about 120 F and sent to its intended use, with either additional carbon dioxide for C-level controlled carburization, as a protective gas during bright annealing and tempering or with the addition of ammonia in nitro-carburization.

On Increasing Powder Carbon Steels Properties Using Activating Additives
Int. J. of Applied Mechanics and Engineering, 2020, vol.25, No.2, pp.192-201 DOI: 10.2478/ijame-2020-0029 Brief note ON INCREASING POWDER CARBON STEELS PROPERTIES USING ACTIVATING ADDITIVES L. DYACHKOVA O.V. Roman Powder Metallurgy Institute Belarusian National Academy of Sciences 41, Platonov st., 220005 Minsk, BELARUS E-mail: [email protected] In this paper, the possibility of increasing powder carbon steels properties by activation of carbon diffusion into the iron base during sintering process due to the introduction of the thermally split graphite (TSG), macromolecular compounds (MC) and sodium bicarbonate was investigated. It was found that the introduction of these additives allows obtaining homogeneous structures at a sintering temperature of 100–200 °C lower than that traditionally used for sintering of powder carbon steels. Such structures provide increased mechanical properties of powder carbon steels. The addition of sodium bicarbonate increases the diffusion rate of carbon into iron at a temperature of 950 C by 1.8 times, at 1000 °C by 1.5 times, and at 1100 °C by 1.2 times. Key words: powder carbon steels, activating additives, structure, mechanical properties. 1. Introduction Powder metallurgy is one of the most progressive processes for parts manufactured for various purposes. Numerous technological processes of powder metallurgy can reduce the consumption of materials, manufacturing energy and allow automation of the process. The necessary combination of manufacturability and reliability of parts, as well as obtaining the required material properties, are ensured by controlling the processes of structure formation. The structure and properties of powder carbon steels, in which carbon is the main alloying element, depend on the degree of homogeneity of the structure formed during sintering.

Gas Carburizing Fundamentals
Fundamentals of Mass Transfer in Gas Carburizing by Olga Karabelchtchikova A Dissertation Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE In partial fulfillment of the requirements for the Degree of Doctor of Philosophy in Materials Science and Engineering ________________ November 2007 APPROVED: ________________________________________ Richard D. Sisson, Jr., George F. Fuller Professor, Advisor Director of Manufacturing and Materials Engineering ABSTRACT Gas carburizing is an important heat treatment process used for steel surface hardening of automotive and aerospace components. The quality of the carburized parts is determined by the hardness and the case depth required for a particular application. Despite its worldwide application, the current carburizing process performance faces some challenges in process control and variability. Case depth variability if often encountered in the carburized parts and may present problems with i) manufacturing quality rejections when tight tolerances are imposed or ii) insufficient mechanical properties and increased failure rate in service. The industrial approach to these problems often involves trial and error methods and empirical analysis, both of which are expensive, time consuming and, most importantly, rarely yield optimal solutions. The objective for this work was to develop a fundamental understanding of the mass transfer during gas carburizing process and to develop a strategy for the process control and optimization. The research methodology was based on both experimental work and theoretical developments, and included modeling the thermodynamics of the carburizing atmosphere with various enriching gasses, kinetics of mass transfer at the gas-steel interface and carbon diffusion in steel. The models accurately predict: 1) the atmosphere gas composition during the enriching stage of carburizing, 2) the kinetics of carbon transfer at the gas-steel surfaces, and 3) the carbon diffusion coefficient in steel for various process conditions and steel alloying.

Diagnostics Adapted for Heat-Treating Furnace Environment
Diagnostics Adapted for Heat-Treating Furnace Environment Diagnostics developed for the in situ monitoring of rocket combustion environments were adapted for use in heat-treating furnaces. Simultaneous, in situ monitoring of the carbon monoxide, carbon dioxide, methane, water, and hydrogen concentrations in the endothermic gas of a heat-treating furnace were demonstrated under a Space Act Agreement between the NASA Lewis Research Center, the Heat Treating Network, and Akron Steel Treating Company. This endothermic gas, or "endogas," is produced in a catalytic process, where natural gas is "cracked" in the presence of air. Variations in the composition of the natural gas supplied lead to variations in the composition of the endothermic gas. These variations could lead to an unacceptable quality of steel products that are hardened through the carborization process that uses this gas. Conventional methods of monitoring the endogas include measuring the dew point of the gas and the oxygen concentration. From these data, the carbon monoxide content of the gas can be calculated. This carbon monoxide concentration creates the carbon potential needed for carburization. Several weak links are present in this approach. The oxygen monitor deteriorates over time, and the measurement might be inaccurate by 50 percent. Also, the chemistry equations, which are based on several assumptions, such as secondary species concentrations, provide only an approximate estimate of the carbon monoxide concentration . To address these weaknesses, we investigated a new method based on ordinary Raman spectroscopy, in which the carbon monoxide concentration is measured directly and in situ. This method measures the laser light scattered from the molecules.

Metallurgical Processes Cracked Ammonia As a Forming Gas for Hardening of Metals
Metallurgical Processes Cracked Ammonia as a Forming Gas for hardening of metals Application Notes Background Hydrogen gas is widely used for the bright hardening of many kinds of metals. There are two main delivery methods for this process - bulk hydrogen from storage cylinders and cracked ammonia. Both delivery methods have advantages and disadvantages - cost and fire hazard in the case of pure hydrogen and corrosion risk and human safety being the main considerations in the case of cracked ammonia. However, generally nowadays cracked ammonia plant is the more common method of provision of a reducing/hardening atmosphere for steel and other metals furnaces. What is the process in an ammonia cracker? Pressurised liquid ammonia is heated in order to vaporise it and is then passed over a nickel catalyst at a temperature of about 1000 oC, which causes it to Steel Furnace dissociate into its component parts - hydrogen and nitrogen. The chemical equation for this reaction is: Applications for dissociated 2NH3 a N2 +3H2 ammonia The diagram below (courtesy of HYAM web site) illustrates the cracking process. The forming gas is used in conveyer furnaces and in tube furnaces for annealing processes in a reducing atmosphere: brazing, sintering, de-oxidation, and nitrization. Further applications for forming gas are: Hydrogenation of organic Brazing Metal annealing compounds Sintering Stainless steel wire anneal Galvanization Deoxidization Metal powder anneal Production of Forming Gas Nitrization Bimetal products anneal As a result of complete dissociation into hydrogen and nitrogen, very little un- Gas Properties dissociated ammonia remains and the dew point temperature of the resulting gas should be very low (well below -30°C).

Why Heat-Treating Furnaces Look the Way They Do, Part 2 by Jack Titus
HOT SEAT: Heat treating is not for the faint of heart Why heat-treating furnaces look the way they do, Part 2 By Jack Titus Natural gas is a clean-burning fossil fuel that, when ignited with air, produces heat, carbon dioxide (CO2), and water in vapor form (H2O). Mix one cubic foot of gas plus 10 cubic feet of air, a spark and the result will be one cubic foot of CO2 plus two cubic feet of H2O and eight cubic feet of nitrogen. Two cubic feet of water vapor equals 3.2 tablespoons of water. Nitrogen obviously does not burn, but it still must be heated and contributes to the convection heat transfer of energy. Anyone who has used a ventless natural gas room space heater can attest to the quantity of water that condenses on windows in cold climates. A 20,000 BTU heater requires 200 cubic feet of natural gas plus 2,000 cubic feet of room air. Per the formula above, the resulting combustion will produce 200 cubic feet of CO2 plus 400 cubic feet of H2O, or about two quarts per hour. Gas-fired heat-treating furnaces use natural gas in two ways: They heat the process hot zone with a stoichiometric mixture (ideal combustion) of one part of natural gas to 10 parts of air to produce the endothermic Figure 1 (Courtesy/AFC-Holcroft) atmosphere for carburizing. Since no combustion reaction is perfect, it’s possible that a small fraction mium, and iron alloys. This method is used where a special atmosphere or parts per million (ppm) of CO could be produced, therefore excess air is is used to protect parts with nitrogen or carburize with endothermic gas.
