Description

Technical Field

[0001] The utility model relates to the technical field of coke coking, in particular to a high-strength coke coking device. Background Art

[0002] Coke refers to the process of heating coking coal to about 1000℃ (high temperature dry distillation) under air-tight conditions to produce coke, coke oven gas and other coking chemical products through thermal decomposition and coking. Metallurgical coke has high carbon content, high porosity and high strength. It is an important fuel and reducing agent for blast furnace ironmaking, and also a supporting agent and loosening agent for the entire blast furnace column. A coke oven is a furnace used to refine coke. A coke oven consists of a carbonization chamber, a combustion chamber, a regenerator, a ramp area, a furnace roof, a foundation, a flue, etc.

[0003] At present, coking raw materials are not screened during coking in coke ovens. The strength of coke often depends on the size of the coking raw materials, resulting in the raw materials being too large or too small during coking. Coking raw materials that are too large or too small will affect the quality of coke and cannot guarantee the strength of the coke after coking. Utility Model Content
