At present, 98.5% of the world's annual iron ore consumption is processed by blast furnaces. Therefore, the mainstream of modern ironmaking is the blast furnace method. However, this does not mean...
Steel is an alloy consisting mainly of iron, carbon and other elements. According to its carbon content, iron can be divided into pig iron and wrought iron. Pig iron contains between 2.11 and 4.5 perc...
Iron is the earliest discovered, the most widely used and the most used metal in the world, accounting for about 95% of the total metal consumption. Iron ore is a mineral aggregate containing iron ele...
Graphite electrode, which is mainly made of petroleum coke and needle coke as raw materials and coal asphalt as binder, is made by calcining, batching, mixing, pressing, calcinating, graphitization an...
Graphite electrode can be divided into ordinary power graphite electrode, high power graphite electrode and ultra-high power graphite electrode according to the quality index.The physical and chemical...
Today I will share with you the production process of graphite electrode.1. Calcination: Carbon material undergoes heat treatment at high temperature to drain out the moisture and volatile components,...
As is known to all, hot rolling and cold rolling are both procedures of forming section steel or plate, which have great influence on the microstructure and properties of steel. Hot rolling is the mai...
The maximum thickness of common CRS is 8mm. It is usually made from hot-rolled coils to produce beautiful and easy to use cold pressed steel. Each coil can reach 13.5 tons. Instead, stainless steel is...
Steel slabs are the second stage in steel production. They are hot-rolled and taken out directly during the casting process of steel. Steel slabs are highly malleable and flexible with square cross se...
Definition: steel slab refers to semi-finished products used in the production of steel, generally can't be directly used by the community.Material: continuous casting steel square billet and rect...
Hot rolled coils are steel plates made of slabs as raw material and rolled by rough rolling and finishing rolling units after heating. Generally it includes the medium-thick and wide steel strip, the ...
Common steel products are hot rolled steel and cold pressed steel. In general, mechanical properties of hot rolling are better than that of cold rolling. After heat treatment, steel's tensile, yie...
Cold rolled steel is made of hot rolled coils at room temperature and then rolled below the crystallization temperature. Many steel mills in China can produce them. Among them, the ones delivered in p...
Medium carbon steel is a kind of carbon steel with a carbon content of 0.25% to 0.60%. It includes most of high-quality carbon structural steel and part of ordinary carbon structural steel. Medium car...
Iron ore fines is a kind of ore fines which is made from iron ore (ore containing iron elements or iron compounds) through processing, such as ore processing, crushing, sorting, and grinding. The type...
