Description:

calcined anthracite coal is made from Ningxia Baiyun anthracite. F.C is between 90%-95%. Reduce the cost of steelmaking effectively by replacing the traditional petroleum coal of carburant. Also can improve the Carbon content in steel-making and Ductile iron foundry.

Application:

Carbon raiser has two main uses, namely as the fuel and additive
Used in steel mill ladles, melting, holding and blast furnaces as recarburizer
Used as a substitute of Calcined Petroleum Coke in a particular application

The Electrical Calcined Anthracite is used the best quality anthracite as raw materials through high temperature calcined at over 2000 by the DC electric calciner with results in eliminating the moisture and volatile matter from anthracite efficiently, improving the density and the electric conductivity and strengthening the mechanical strength and anti-oxidation.
It has good characteristics with low ash, low resistvity, low sulphur, high carbon and high density. It is the best material for high quality carbon products to production of electrode, and used in cathode blocks for aluminum industry.

Calcined Anthracite coal is produced when Anthracite is calcined under the temperature of 1240 in vertical shaft furnaces, mainly used in electric steel ovens, water filtering, rust removal in shipbuilding and production of carbon material.

Carbon raiser is a carbon material, produced at high temperatures and used for carburization of steel and cast iron.
It is applied during the steelmaking with low cast iron content (allow of steel and carbon) in charge in oxygen converter and electrosmelting processes. In metallurgy carbon raiser (milled graphite) is widely used for slag foaming, during coal graphite production, as a filler for graphite-reinforced plastic.

Product Description

Using calcined anthracite coal carburizing agent and cast iron using carburizing agent steel, and other materials are also useful for adding to the carburant carburant is applied, steelmaking, iron carbon materials. High quality carburizing agent is essential to producing high quality steel auxiliary additives.



Usage:

For 1-5 T furnace:
- while a small amount molten iron in the furnace,
- or with some molten iron remained, add the carbon additive one-time,
- then add the other material.
which can make carbon additive fully absorbed.


For greater than 5 T furnace:
- mix proper carbon additive with charging material as suggested first,
- and then along with the increase of charging material gradually,
- that is, before the molten metal rising up to about 2/3 height of furnace,
- all carbon additive shall be added.
It guarantees sufficient melting & absorbing time before molten metal out, and improves the absorption of carbon.

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.
We have established a long-term cooperative relationship with anthracite plants in Vietnam. We also provide calcined anthracite coal and dried anthracite coal from Vietnam:
