The Early Medieval Cutting Edge of Technology: An archaeometallurgical, technological and social study of the manufacture and use of Anglo-Saxon and Viking iron knives, and their contribution to the early medieval iron economy Volume 1 Eleanor Susan BLAKELOCK BSc, MSc Submitted for the degree of Doctor of Philosophy Division of Archaeological, Geographical and Environmental Sciences University of Bradford 2012 Abstract The Early Medieval Cutting Edge of Technology: An archaeometallurgical, technological and social study of the manufacture and use of Anglo-Saxon and Viking iron knives, and their contribution to the early medieval iron economy Eleanor Susan Blakelock A review of archaeometallurgical studies carried out in the 1980s and 1990s of early medieval (c. AD410-1100) iron knives revealed several patterns (Blakelock & McDonnell 2007). Clear differences in knife manufacturing techniques were present in rural cemeteries and later urban settlements. The main aim of this research is to investigate these patterns and to gain an overall understanding of the early medieval iron industry. This study has increased the number of knives analysed from a wide spectrum of sites across England, Scotland and Ireland. Knives were selected for analysis based on x-radiographs and contextual details. Sections were removed for more detailed archaeometallurgical analysis. The analysis revealed a clear change through time, with a standardisation in manufacturing techniques in the 7th century, and differences between the quality of urban and rural knives. -

Centre for Archaeology Guidelines
2001 01 Centre for Archaeology Guidelines Archaeometallurgy Archaeometallurgy is the study of metalworking structures, tools, waste products and finished metal artefacts, from the Bronze Age to the recent past. It can be used to identify and interpret metal working structures in the field and, during the post-excavation phases of a project, metal working waste products, such as slags, crucibles and moulds.The technologies used in the past can be reconstructed from the information obtained. Scientific techniques are often used by archaeometallurgists, as they can provide additional information. Archaeometallurgical investigations can provide evidence for both the nature and scale of mining, smelting, refining and metalworking trades, and aid understanding of other structural and artefactual evidence.They can be crucial in understanding the economy of a site, the nature of the occupation, the technological capabilities of its occupants and their cultural affinities. In order that such evidence is used to its fullest, it is essential that Figure 1 Experimental iron working at Plas Tan y Bwlch: archaeometallurgy is considered at each stage of archaeological projects, removing an un-consolidated bloom from a furnace. and from their outset.

Using Cooled Mirror Hygrometers to Optimize Cold & Hot Blast Furnace
Application Note Using Cooled Mirror Hygrometers to optimize Cold & Hot Blast Furnace processes Application Background The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron. The blast furnace is a huge, steel stack lined with brick. Iron ore, coke and limestone are dumped into the top, and preheated “hot blast” air is blown into the bottom. The raw materials gradually descend to the bottom of the furnace where they become the final products of liquid slag and liquid iron. These liquid products are drained from the furnace at regular intervals. The hot air that was blown into the bottom of the furnace ascends to the top in 6 to 8 seconds after going through numerous chemical reactions. These hot gases exit the top of the blast furnace and proceed through gas cleaning equipment where Cold Blast, Hot blast & Stoves particulate matter is removed from the gas and the gas is cooled. This gas has a considerable energy value so it is burned as a fuel in the "hot blast stoves" which are used to preheat the air entering the blast furnace to become "hot blast". Any of the gas not burned in the stoves is sent to the boiler house and is used to generate steam which turns a turbo blower that generates the compressed air known as "cold blast" that comes to the stoves. Why is Moisture Critical? This process can be optimized by proper control of the flame temperature, which is in turn affected by the moisture content of the blast air. -

Blast Furnace Stove Dome and Hot Blast Main
BLAST FURNACE STOVE DOME AND HOT BLAST MAIN The quality and composition of iron produced in the blast furnace is directly related to the hearth temperature. This, in turn, is dependent on the temperature of the hot blast delivered from the blast furnace stoves. To maximise the efficiency of the stoves, they are operated at high temperatures, close to the safe working limit of the refractories. This makes it critical to carefully monitor the stove temperature. BLAST FURNACES AND STOVES Blast furnaces heat iron ore to a period of accumulation, flow is produce the iron required as a reversed, and the hot stove is used raw material for steel-making.

The insufficient availability and the high price of the coking coals have forced many countries to research and adopt the non-coke-consuming reduction and metal manufacturing processes (non-coke metallurgy, direct reduction, direct processes). This paper represents a survey of the most relevant processes from this domain by the end of 2000, which display a constant increase in the modern process metallurgy. Keywords: iron, coal, direct reduction, reduction smelting, main processes, reduction. 1. Introduction The processes that produce iron by reduction of iron ore below the melting point of the iron produced are generally classified as direct reduction processes, and the product is referred to as direct reduced iron. The processes that produce molten metal, similar to blast furnace liquid metal, directly from ore are referred to as direct smelting processes. In some of the processes the objective is to produce liquid steel directly from ore and these processes are classified as direct steelmaking processes. J. Min. Met. 38 (3 ‡ 4) B (2002) 123 A. Markoti} et al. These broad categories are clearly distinguished by the characteristics of their respective products, although all of these products may be further treated to produce special grades of steel in the same steelmaking or refining process [1].
