Problems solved by technology

[0002] In the prior art, industrial metallurgical molded coke mostly uses anthracite, and coal tar pitch and coal tar are used as binders. The molded coke produced has no reporting holes, poor air permeability, and many faults. block, resulting in the failure of normal coke production, directly affecting the production and popularization of coke

Embodiment Construction

[0025] 1. Select 100 parts of cohesive coal, 5 parts of adhesive, and 5 parts of anti-sticking agent; first, make anti-sticking agent, which is prepared by the following method, and choose 6 parts of cornstarch and 180 parts of water for mixing , heated to 50-65°C, then added a saturated solution of 9 parts of sodium hydroxide and water, stirred to make it mature, then took 20-30 parts of cornstarch, added quantitative water and stirred, and heated to 25-30°C at the same time to prepare Starch slurry, and then stir simultaneously with mature starch, finally pour the mixed solution of polyvinyl acetate and water 1:5, 6 parts, into the above starch slurry and stir well.

[0026] Second, the production process of coke

[0027] Coal washing→drying→crushing→kneading→adding binder→forming→drying→anti-sticking treatment→coking (refining tar, gas)→cooling→finished product. The binder adopts 3-9 parts of humate.

[0028] The selected cohesive coal is washed with water to remove the a...

Abstract

The present invention relates to a method for producing industrial metallurgical formed coke by using binding coal, weak caking coal, fat coal and gas fat coal. It is made up by using the following raw materials: (by weight portion) coal 100 0portions, humate (powder) 2-5 portions and detackifier 4-9 portions, in which the detackifier is made up by using the following raw materials: (by weight portion) mixture of corn starch 3-9 portions and water 100-200 portions, sodium hydroxide 4-12 portions, liquid mixture of polyvinyl acetate and water according to the ratio of 1:5, 2-8 portions and starch paste. As compared with existent technology, it is short in coking time, can effectively control environmental pollution, its block coke rate is high, production cost is low, and it can a handred per cent extract tar and lots of gas.

Description

technical field [0001] The invention belongs to the technical field of coal processing, and in particular relates to an industrial metallurgical coke produced by using caking coal, weak caking coal, fat coal, gas fat coal and the like. Background technique [0002] In the prior art, industrial metallurgical molded coke mostly uses anthracite, and coal tar pitch and coal tar are used as binders. The molded coke produced has no reporting holes, poor air permeability, and many faults. block, resulting in the coke can not be normally out of the furnace, directly affecting the production and popularization of coke. Contents of the invention [0003] The invention solves the technical problem of coking coke produced from caking coal, and provides a kind of coke with good cohesiveness, which makes the coke agglomerate under heat in the coking furnace, and keeps the original shape and separates the coke after the coke is formed. state of industrial metallurgical coke. [0004] T...
