Abstract

The invention discloses a method for preparing special bleached bead bricks for constructing a super-strength coke oven bottom. The method comprises the following steps: S1, mixing the following components in parts by weight: 150-190 parts of water, 1100-1700 parts of bleached beads, 240-350 parts of steel slag, 350-640 parts of clay, 30-75 parts of alumina powder, 50-100 parts of waste iron powder, 320-430 parts of fly ash and 45-65 parts of cement, and performing mechanical stirring in a stirring machine for 20-35 min according to the ratio so as to obtain a mixture; S2, adding 6.5-14 partsof a binder and 2.1-8.0 parts of a water-reducing agent into the mixture obtained in the step S1, performing mechanical stirring in a stirring machine for 8-15 min and performing uniform stirring so as to obtain mixture slurry; S3, taking out the mixed slurry obtained in the step S2, pressurizing the mixed slurry for 2-3 minutes, and uniformly cutting the pressurized mixed slurry so as to obtain brick blanks; S4, performing air drying on the brick blanks obtained in the step S3; and S5, firing the brick blanks air dried in t he step S4. The bleached bead bricks prepared by using the method have the advantages of being high in pressure strength and simple to prepare.

Description

technical field [0001] The invention belongs to the technical field of preparation of floating bead bricks, in particular to a preparation method of special floating bead bricks for super-strength coke oven bottom masonry. Background technique [0002] At present, a coke oven is a furnace usually made of refractory bricks and refractory blocks, which is used to convert coal to produce coke, and is a kiln for refining coke with coal. It is the main thermal equipment for coking. Modern coke oven refers to the horizontal chamber coke oven whose main purpose is to produce metallurgical coke and can recover coking chemical products. It consists of a furnace body and auxiliary equipment. The coke oven body consists of furnace roof, combustion chamber, carbonization chamber, chute area, regenerator and other parts, and is connected by flue and chimney. The bottom of the coke oven is built on the concrete foundation, and the whole part of the coke oven is built above the bottom of ...
