Casting type coke production method and apparatus system used thereof

Abstract

The present invention relates to a production method of foundry shaped coke and its equipment system for producing said foundry shaped coke. Said method includes the procedures of preparing material,pulverizing, cold stirring, hot stirring, forming and carbonization and coking, and its equipment system includes material-preparing chamber, pulverizing machine, cold stirring machine, hot stirring machine, forming machine and carbonizing furnace, etc.

Description

technical field [0001] The invention relates to coke used in the metallurgical industry, in particular to a production method of casting mold coke and an equipment system used therefor. Background technique [0002] At present, most of the coke ovens used in my country's coking industry are 58-II or 80 types modified on the basis of 58-type ovens. The reheating coke oven has an air regenerator and a gas regenerator in the lower part of each carbonization chamber. In a combustion chamber, a pair of adjacent fire passages and four connected regenerators form a corresponding heating unit. This kind of coke oven basically uses main coking coal plus coal blending for coking. The disadvantage is that the coking coal reserves are small and the price is high, which cannot meet the increasing demand for coking. [0003] Because it is mainly coking coal, the volatile content of the raw material is about 30%, and 15% of the volatile content needs to be recovered by chemical production....

AI Technical Summary

Problems solved by technology

This kind of coke oven basically uses main coking coal plus coal blending for coking. The disadvantage is that the coking coal reserves are small and the price is high, which cannot meet the increasing demand for coking.

[0003] Because it is mainly coking coal, the volatile content of the raw material is about 30%, and 15% of the volatile content needs to be recovered by chemical production. Therefore, a lot of recovery equipment is required, and the investment is large, and in the recovery process, cyanide and other substances are recovered. , causing massive water pollution and air pollution, which is not conducive to environmental protection

This kind of coke oven needs huge mechanical equipment such as coal loading car, flat refining (or tamping) device, coke pushing car, etc. when entering and discharging materials. The working environment is poor, and it is difficult to realize mechanization and automation of operation.

[0004] The raw materials used in this kind of coke oven contain a lot of harmful impurities such as ash and sulfur, and are not easy to be washed. After entering the furnace, the raw materials are piled up together, resulting in products with different lumps, high porosity, and poor coke quality.
