Clean heat recovery coke oven

Clean heat recovery coke oven The clean coals of different varieties and qualities are stacked separately in the coal yard, and the coking coal is pushed into the respective coal receiving pits by a forklift according to the operation regulations, and the coal blended in the coal receiving pits is transported by the belt conveyor to the impact blow hammer mill. Before entering the pulverizer, go through the electromagnetic iron remover to remove the metal impurities in the coal. In the impact blow hammer mill, the mixed coal is crushed to a qualified particle size of less than 3mm, reaching 90%. The crushed qualified coking coal is transported by belt conveyor to the coke oven coal tower for storage for coking.What needs to be done for heat treatment with vacuum oil quenching furnace? There is a tamping station under the coal tower. When the coke oven uses coal, it is directly loaded into the hopper of the distributing trolley from the nozzle of the coal tower. The capacity is about 1/2 the weight of coal cakes. The chute puts the coal evenly into the tamping coal box, and tamps the coal into briquettes. Coal cake density 1.1-1.2t/m3.Pressureless Sintering of Silicon Carbide Ceramics The crushed briquettes are sent to the coal loading car together with the coal box, and are transported to the carbonization chamber to be released from the oven. After the coke push rod pushes out the mature coke in the carbonization chamber, quickly close the furnace door on the coke side, push the briquettes together with the coal box into the carbonization chamber, then lock the baffle at the end of the briquettes on the furnace mouth, and pull out the coal-charging truck , quickly turn off the machine side furnace.Prevention method for grinding cracks of vacuum carburizing and quenching gears Since the side wall of the carbonization chamber and the furnace bottom flame passage have a certain amount of heat, part of the coking coal is heated to precipitate raw gas. There are adjustable primary and secondary air inlets and regulating devices on the vault and the furnace wall. The combustion of air and raw coal gas generates heat to heat the furnace roof, and the briquettes are heated through heat conduction and heat radiation.Pit Type Furnace Nitriding Process And Operating Procedures
