Actions Aimed at Increasing the Beneficial Use of Foundry Sand
Draft 9/17/09 ACTIONS AIMED AT INCREASING THE BENEFICIAL USE OF FOUNDRY SAND A MULTI-STAKEHOLDER ACTION PLAN September, 2009 Draft 9/17/09 September, 2009 Over the past year, a core planning group has worked in consultation with a broad group of stakeholders, to consider various actions for increasing the beneficial use of foundry sand. This process has produced a Multi-Stakeholder Action Plan (MAP) which identifies key challenges to increased beneficial use, and a comprehensive set of actions aimed at increasing the beneficial use, of foundry sands. These actions will a) document the economic and environmental case for beneficial use, b) foster sustainable markets linking sand generators with end users, c) address regulatory processes, and d) establish a coordinated framework to oversee implementation and measure progress. The planning process also generated a set of Initial Priority Actions that various key parties are undertaking over the next few years. These actions will address many of the challenges identified in the MAP and lay the groundwork for implementation of additional MAP actions. Currently, the foundry industry estimates that about 28% of sands are directed to beneficial use. The industry’s national trade association—the American Foundry Society—has set a goal of 50% beneficial use by 2015. During the development of the MAP, the stakeholders listed below expressed support for this goal and committed to work together towards achieving it through implementation of the Initial Priority Actions.

Integrating Cold Forging and Progressive Stamping for Cost
Precision Cold Forging Progressive Stamping Enables Cost Effective Production of Complex Parts Overview Both Cold Forging and Precision Stamping are proven technologies used in the fabrication of parts for a wide range of industries. Many of our previous Tech Bulletins have detailed the benefits of each technology, and in several cases, these processes are thought of as an either- or choice. This Tech Bulletin provides insights into how combining these technologies in a process known as Precision Cold Forging Progressive Stamping can provide significant synergies and additional benefits for the cost-effective production of complex parts that cannot easily be created by either technique alone. What is Cold Forging? As detailed in other Interplex Tech Bulletins, Cold Forging is essentially an impact forming process in which billets of raw material are compressed and reformed into a part’s desired shape. Cold Forging offers the key benefits of lower costs, rapid high-volume throughput, high part strength, and very efficient material utilization. This, in comparison to processes like machining that remove Figure 1 – Cold Forged significant amounts of raw material rather than simply reforming all the Automotive Seat Belt Gear material into the desired shape. What is Precision Stamping? Precision Stamping is another proven technology that uses a press and die to form sheet metal, blanks or coil material into desired shapes. Variations of the stamping process can effectively yield several different output results including bending, embossing, flanging, coining, etc. Like Cold Forging, Precision Stamping typically offers high material utilization with minimal waste and can also deliver high-volume production results. -

Doctor of technical sciences, professor Department of “Mechanical engineering and automation”, Fergana Polytechnic Institute, Fergana, Uzbekistan Assistant department of “Mechanical engineering and automation”, Fergana Polytechnic Institute, Fergana, Uzbekistan ABSTRACT: In conditions of increasing globalization at modern production facilities, the ability of a modern engineering company to compete in the production of high-tech products is determined by the technological capabilities of the product. These opportunities are represented by quality improvement, timely implementation and low economic costs. Increasing productivity in this direction is an important achievement in the development of modern engineering production. With the expansion of the product range, the dynamic development of such production involves a constant increase in the need for technological equipment of CAD / CAM / CAE systems. It is characterized by high-quality and resource-intensive production conditions, the development of new products, the development of technological systems and complex production technologies. KEY WORDS: system, G-code, RDB machine, software, production, design, details, cutting tool, cutting process I. INTRODUCTION Read more about the project, details of the maintenance, and the details of the technology and functional details of the role of the manufacturer in the production of machine tools. We are working on the problems of machine-to- machine forecasting. CAD / CAM / CAE. The role and importance of CAD / CAM / CAE systems in the design and manufacture of engineering products indicates that the design department at the manufacturing enterprise should take into account financial resources in the production and production of marketable products. -

Metals in the Bible: Silver (Part 1)

Nevertheless, (To be continued) New feature Metals in the Bible 3. Silver (Part 1) Peter Hemingray In 1996 and 1997 The Testimony published two two-part articles under the title, “Metals in the Bible”, in which we looked at iron and copper.1 We considered the ancient technology of iron, and how this knowledge helps illuminate the Biblical references to it. In particular, we saw how the introduction of iron during the period of the conquest affected the Israelites, who had to overcome superior technology through the power of God. For copper (or brass, as the AV terms it) the ancient metalworking methods were illuminated with illustrations from Timnah in Palestine, and we argued for the symbology of copper in the Bible being primarily that of strength, and only rarely that of the strength of sin. The intention was to complete these studies on metals of the Bible by considering silver, then gold. This we have now done in two further two-part articles to be published in this and the coming months, God willing. E WILL CONTINUE the theme of il- • examine the references to refining and cruci- lustrating the Biblical passages about bles in the light of our knowledge of ancient Wmetals with descriptions of the ancient metalworking practices metalworking techniques, as we consider silver, • look at the few references to lead in the Bible, the next metal up in Nebuchadnezzar’s image often associated with silver for reasons we after the iron and brass already considered. -

DROSS in DUCTILE IRON by Hans Roedter, Sorelmetal Technical Services
98 DROSS IN DUCTILE IRON by Hans Roedter, Sorelmetal Technical Services WHAT IS “DROSS ”? magnesium with other elements. Dross also Dross is a reaction product which is formed from occurs in the form of long stringers instead of Mg treatment and during subsequent reoxidation concentrated “slag like” areas. When it occurs in of Mg rejected from the molten metal before it this string like form it acts like cracks or flake solidifies. It is therefore just another word for a graphite in the structure and so fatigue strength specific type of slag (reaction product). and impact strength of the material are lowered considerably. The reaction binds magnesium with sulphur, oxygen and silicon and forms continuously. This “dross” is light weight and so it will generally be found in the upper surfaces and under cores, but it can be entrained throughout the metal as well, especially with colder pouring tempera - tures. It is very difficult to completely avoid the reaction of magnesium with these other elements, since we need magnesium to form nodules. We are always confronted with the problem of dross in the production of Ductile Iron. WHAT IS PROMOTING “DROSS ” AND WHAT CAN BE DONE TO KEEP THE “DROSS ” OUT OF THE CASTING ? Since “dross” is always connected with magnesium, it is necessary to keep the magnesium level as low as possible. Good inoculation practice with some late inoculation in conjunction with sufficient magnesium will When looking at “dross” in the microscope you produce nice round small nodules. See will almost always find flake graphite in Suggestion Sheet 76. -
