The supply of refractory
materials is a key issue for the world steel industry. Yilong Refractory manages
refractories that widely used in steelmaking, metallurgy, glass making, cement
making, ceramic making, etc.
Iron ore and coking coal are used mainly in the blast furnace process of
ironmaking. For this process, coking coal is turned into coke, an almost pure
form of carbon, which is used as the main fuel and reductant in a blast
furnace.
Typically, it takes 1.5 tones of iron ore
and around 450 kg of coke
to produce a tone of pig iron, the raw iron that comes out of a blast furnace.
Some of the coke can be replaced by injecting pulverized coal into the blast
furnace.
Scrap iron is mainly used in electric arc furnace steelmaking. As well
as scrap arising from the making and using of steel, obsolete scrap from
demolished structures and end-of life vehicles and machinery is recycled to
make new steel. Around 500 million tones of scrap are melted each year.
Refractory is a common material on
the earth’s surface. Most refractories are located in China , carried to dedicated ports by rail, and
then shipped to steel plants in Asia, Africa, South America and Europe .
Sea freight is an element of major concern for steelmakers today, as the
high demand for raw materials is causing backlogs at ports.
