Cast
iron is an alloy of iron containing carbon. Its composition can additionally
include manganese, phosphoric, silicic, and sulfuric and other components.
Initially, iron ore, fuel materials, fluxes serve as materials for the
production of cast iron.
As
a rule, iron ore is used in the form of raw materials for the production of
cast iron, having iron and other chemicals in the waste rock composition of 30
to 70%, as well as harmful sulfur-and phosphorus-containing compounds. Fuel
material for the production of cast iron is coke, which is the result of dry,
that is, without the participation of air, processing of stone coked coal. The
fluxes used most often quartz, dolomite, sandstones and lime stones, allow
lowering the melting temperature of the waste rock, and also leading it along
with the ash from the fuel to the slag. The same process is followed for the Powder
Coated Fence.
Domain Production of Cast Iron
The
greatest application was found in the production of cast iron blast furnace
process. It includes a number of physical, physico-chemical, as well as
mechanical manifestations, observed in the operating blast furnace. The initial
components placed in this furnace (coke, iron-containing materials with fluxes)
are transformed into an alloy of cast iron, the blast-furnace gases emitted
with slags during the passage of all operations. The task of blast furnace
production is the creation of this alloy from iron-containing components by
means of their re-melting in blast furnaces at very high temperatures.
Therefore,
blast furnace shops one of the most important in the structure of the plant for
the production of cast iron. In addition, the production of pig iron in a blast
furnace - the basis for the manufacture of steel, rolls products - the end
products of the metallurgical cycle of other enterprises.
