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 tonnes of iron ore
and around 450kg of coke
to produce a tonne of pig iron, the raw iron that comes out of a blast furnace.
Some of the coke can be replaced by injecting pulverised 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 tonnes 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.
