Product Description

Foundry coke

Foundry Coke Used in a cupola to produce cast andductile iron products. It is a source of heat and alsohelps maintain the required

carbon content of themetal product.

Foundry coke

Coke quality evaluation:1) Sulfur in coke: Sulfur is one of the harmful impurities in pig iron smelting, which reduces the quality of pig iron. In the steelmaking pig iron, the sulfur content is more than 0.07%, which is waste. 11% of the sulfur brought into the furnace from the blast furnace charge comes from the ore; 3.5% comes from limestone; 82.5% comes from coke, so coke is the main source of sulfur in the charge. The level of coke sulfur directly affects the production of blast furnace iron. When the coke sulfur content is greater than 1.6%, the sulfur content increases by 0.1%, the coke usage increases by 1.8%, the limestone addition increases by 3.7%, the ore addition increases by 0.3%, and the blast furnace output decreases by 1.5-2.0%. Not more than 1%, the metallurgical coke used in large and medium sized blast furnaces has a sulfur content of less than 0.4-0.7%.2) Phosphorus in coke: The metallurgical coke phosphorus content for iron making should be below 0.02-0.03%.3) Ash in coke: The effect of coke ash on blast furnace smelting is very significant. The coke ash is increased by 1%, and the coke consumption is increased by 2 to 2.5%. Therefore, the reduction of coke ash is very necessary.4) Volatile matter in coke: According to the volatile content of coke, the coke maturity can be judged. If the volatile matter is greater than 1.5%, it means coke; if the volatile content is less than 0.5 - 0.7%, it means overheating. Generally, the mature metallurgical coke is about 1%.5) Moisture in coke: Moisture fluctuations may cause coke to be misaligned, causing fluctuations in furnace conditions. In addition, the increase in coke moisture will make the M40 high and the M10 low, which will bring errors to the drum index.6) Screening composition of coke: The particle size of coke in blast furnace smelting is also very important. China's past coke particle size requirements are: for large coke ovens (1300 - 2000 square meters) coke grain size is greater than 40 mm; medium and small blast furnace coke grain size is greater than 25 mm. However, tests at some steel mills have shown that coke particle size is better at 40 - 25 mm. Cokes larger than 80 mm should be granulated so that the particle size range does not change much. In this way, the coke has a uniform block size, a large gap, a small resistance, and a good running condition.
