What is the peg steel?

The term crucible steel can be somewhat misleading because it does not apply to a specific steel product, but rather for a specific steel production process. The steel process of the crucible involves melting of material such as forged iron, cast iron and blister in small foundry kellers for carbureization or decarburizing. During these processes, the carbon is either scattered or removed from the stock to create optimal metallurgical properties in the finished product. After melting, the crucible is removed from the furnace and the steel is poured into ingot forms. The steel process of the crucible is one of the oldest documented methods of steel production and although it has been replaced by more efficient methods, it is still used to produce a small amount of high -quality materials for specialized applications.

steel is a combination of iron and a small amount of carbon. Combinations such as these are known as alloys with ingredients, in this case carbon, improving the quality of the basic material and lending specific characteristics to the final product. For example, steelIt is heavier than forged iron, less fragile than cast iron and has better wear and corrosion properties than one. Steel can be produced in different ways, most of which include iron melting in the presence of a carbon source. This process causes small amounts of carbon to be distracted into molten iron with typical carbon concentrations in the range of 0.2% to 2.1% depending on the intended use of the alloy.

One of the oldest forms of steel production is the cup process; The first reliable documentation of cruising steels is medieval Islamic records of approximately 1050. The basic principle of steel centers produced by crucibles around the melting of metal supplies in containers or containers made of various refractory materials sufficiently small to manipulate one or two people. Containers or cups are charged with different metals, including forged iron, cast iron or blisters and fired in special furnaces,to melt the charge. Low -carbon materials, such as forged iron, are complemented by a carbon source such as coal that carbourizes or fills the melt with carbon. On the other hand, a carbon containing material contains too high for general steel production; This is usually done by exposing the molten material to the oxygen source.

In general, the process begins by heating the white heat in the furnace with coke or gas, when they are removed from the heat source, charged raw materials and returned to the furnace. They are then left for several hours until the raw materials are completely melted. The shredded are then removed from the furnace, any dirt on the molten steel surface is centrifuged and the steel is poured into ingot forms. This process is tija demanding and expensive and has largely been replaced by more economical and high -capacity processes such as Bessamer furnace. However, the high quality of crucible steel meant that this process is still used to produce a small amount of steel for specialized specializationno markets.
