The raw materials for calcining anthracite come from the high quality anthracite in Ningxia Province of China. It is the same name as the famous Hon Gai in Vietna Coal in Vietnam -“King of Coal” in the world. Its main characteristics are low phosphorus, low ash and low sulfur. Therefore, it can be used not only as a carburizing agent in steel smelting and foundry industry, but also in Yin industry. Carbon block Cathodic carbon block, carbon brick Carbon Brick and carbon paste Carbon paste.
The company’s calcined anthracite is through high temperature treatment and screening, uniform particles, is one of the ideal materials for carburizer and electrode paste.
In China, anthracite is usually calcined in electric calciners, rotary kilns and pot furnaces, and the anthracite produced in electric calciners is called as electrically calcined coal (ECA for short) while the anthracite produced in other two calciners is called as general calcined coal (GCA for short).
ECA, during calcining, can have its temperature up to 2000℃, so it is low in volatile matters, good in thermal and electrical conductivity with the powder resistivity about 600 and mainly used in carbon bricks, electrode pastes and cathode carbon blocks with certain requirements for electrical conductivity. Moreover, the proportion and particle size of ECA in such products vary depending on the situation of different enterprises.
The calcination temperature of GCA is about 1200℃ and its electrical conductivity is far inferior to that of ECA, but the sulfur content of anthracite is usually 0.3-0.5%. GCA is widely used in steel and foundry industry as a carburant by virtue of its higher cost performance.
