Background

Quenching is a term specific to coal coking processes, meaning the cooling of refined red hot coke to a temperature convenient for transportation and storage, and for coke oven operation, is the quenching or quenching process. The coal is carbonized at high temperature to generate coke, which is called coking, and the coking process is carried out in a coke oven, and the produced coke is used for metallurgy. When the coking is finished, the temperature of the coke is generally 950-1100 ℃, and the temperature is reduced to below 250 ℃ through quenching. The coke quenching mode includes two modes of in-furnace coke quenching and out-furnace coke quenching, wherein the in-furnace coke quenching is to cool coke in a coke oven by using steam or coal gas and then discharge the cooled coke out of the coke oven.

After the coke is quenched, the cooled coke is stored in a coke quenching bin for a short time, the temperature of the coke is relatively high, the temperature of the coke needs to be reduced to the temperature which can be borne by a conveyor belt in the coke quenching bin, if the coke is naturally cooled, the required time is long, the water content of the coke cannot be controlled, the purposes of the coke are different, the required water content is different, and the control of the water content is an important link.
