87% foundry coke/furnace coke 20-40mm

 _{Metallurgical coke and furnace coke are made from various coals through high temperature (1300°C) process. It is widely used in steelmaking, ferroalloy manufacturing or non-ferrous metal smelting, iron casting manufacturing or other related metallurgical and foundry industries because of its special physical and chemical characteristics: high strength and fixed carbon content, low sulfur and low volatile matter content.}

Coke specifications:

_notes:

_{1. S in coke: S is one of the harmful impurities in the ironmaking process. If the S content exceeds 0.07%, iron is a waste product.}

_{2. P in coke: P content in ironmaking should be below 0.02-0.03%.}

_{3. Ash content of coke: add 1% to ash content, and add 2-2.5% to coke.}

_{4. Volatile matter of coke: According to the content of volatile matter, the degree of maturity of coke can be adjusted.}

_{5. Moisture in coke: Moisture will make M40 higher and M10 lower.}

_size:

_{A. Coke powder: 0-1, 0-3mm}

_{B. Coke particle size: 5-25mm}

_{C. Focus block: 25-80mm}

_{Application of furnace coke}

_{1. Coking is the most important product. More than 90% of the coke in most countries is used in blast furnace ironmaking. The use of coke instead of charcoal in ironmaking has laid the foundation for the modernization of large blast furnaces and is a major milestone in the history of metallurgy.}

_{2. Used in casting and blast furnace smelting of copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metals, acting as reducing agent, heating agent and column skeleton.}

_{3. In the smelting industry, a small amount is used to prepare calcium carbide, carbon disulfide, phosphorus and other elements. Coke fines are also used as sinter fuel in steel joint ventures. Coke can also be used as a raw material for preparing water gas and synthetic raw materials.}

_{4. In order to achieve better technical and economic indicators of blast furnace operation, smelting coke (metallurgical coke) must have corresponding chemical and physical properties, including thermal properties of the smelting process.}

_{5. In addition to being widely used in iron and steel and non-ferrous metal smelting (metallurgical coke), coke is also used in foundry, chemical industry, calcium carbide and ferroalloy.}
