METALLURGICAL COKE, 30-80
Product Description:
Metallurgical coke (met coke) is a high-carbon solid material derived from the carbonization of coking coal in the absence of air at high temperatures (1000–1100°C). The product is used primarily in metallurgical processes as a reducing agent and energy source. It has high mechanical strength, porosity, and low reactivity, making it ideal for use in blast furnaces and other metal smelting applications.
Main Application:
- As a fuel and reducing agent in blast furnaces for iron and steel production.
- As a carbon source in foundries and ferroalloy industries.
- In non-ferrous metal smelting processes (e.g., lead, zinc).
- As a support material in high-temperature chemical reduction reactions.
