Abstract

The invention is a section coke produced by using braize as main raw material, adding in a proper amount of coking coats and adopting pitch and coke tar as binding agent and then making pressure molding process. It has advantages of low production cost and short coking time. A special section coke furnace for producing the section coke, includes an outer furnace body, there is an inner furnace body in the outer furnace body and they form an interlayer between them. The lower part of the inner furnace body has a tilted furnace bottom and there is a reduced-oxygen combustion chamber and a heat storage chamber between the bottom of the tilted furnace bottom and the bottom plane of the furnace body, the reduced oxygen chamber is connected with the heat storage chamber through a top fire mouth and the interlayer, and the interlayer is connected with a flue through a bottom fire mouth.

Description

technical field

[0001] The invention relates to a method for producing molded coke and a special coke oven for producing the molded coke. Background technique

[0002] There are many precedents at home and abroad for using waste coke powder from coking plants to produce molded coke. Chinese patent 94119296 discloses "1 / 3 coking coal with coke powder separate coking: production of high-quality metallurgical coke and metallurgical casting coke", which is to mix 3-7% coke powder in 1 / 3 coking coal, and its purpose is to use coke powder as bone Material, in order to improve the coke's crushing strength, lumpiness, microstrength, coke density, porosity and reactivity and other indicators. This method consumes too little waste coke powder, and has no substantial effect on the disposal of a large amount of waste coke powder discharged from the coking plant.

[0003] Chinese Patent No. 93112040 separates "a method of manufacturing casting mold coke with coke powder", which is to u...
