For the calcined anthracite, fob 320-420usd tianjing port, quotation is valid utill this month, perment term is t/t. But the cost might be different at different purchasing date, so we need to check and update the offer for u again that day when u confirm order date exactly later, please be noted.

The calcined anthracite coal 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 gas calcined coal (GCA for short).

Electrically calcined anthracite coal, Electrical forging material is made from high-quality anthracite and during calcining, the temperature up to 2000 By calining the high-qualityanthracite, the Coal lattice is hanged Then the anthracite becomes half graphitization. Then the material can meet many demands by changing its physical and chemistry character The specification.

Due to 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 coal recarburizer by virtue of its higher cost performance.
