Burdening and blank making device for porous checker brick and manufacturing method of the brick

Abstract

The invention discloses a burdening and blank making device and a manufacturing method for a porous checker brick, and relates to the field of production of porous checker bricks. The brick comprisesthe following components in parts by mass: 35-55 parts of shale; 20-30 parts of coal gangue; 10-15 parts of clay; 13-20 parts of fly ash; 5-8 parts of silica; 3-5 parts of aluminum oxide; 2-6 parts ofmodified copper; 2.5-2.9 parts of graphite powder; 2.5-3 parts of calcium silicate; and 2-4 parts of perlite. The shale, the coal gangue, the clay, the fly ash, the silicon dioxide, the aluminum oxide, the modified copper, the graphite powder, the calcium silicate and the perlite are arranged, so that the cracking and deformation probability of the checker brick is greatly reduced by adding the aluminum oxide, the modified copper and metal elements into traditional ingredients of the checker brick; the graphite powder, the calcium silicate and the perlite are added into the raw material formula, so that the heat-conducting property and the heat-insulating property of the checker brick are greatly improved, the heat-conducting effect of the checker brick is good, and the heat-insulating time is prolonged.

Description

technical field [0001] The invention relates to the field of porous checker brick production, in particular to a porous checker brick batching and blank making device and a manufacturing method thereof. Background technique [0002] Checker brick is a kind of heat-carrying heat storage body with strong heat exchange capacity, large heat storage area, smooth ventilation and low resistance, which is widely recognized and accepted by the world's iron-making industry. Checker brick is a heat transfer material The medium is mainly used in the middle and upper part of the regenerator of the hot blast stove to store heat and play an extremely important role in the process of heating cold air into hot air. [0003] Most of the existing checker brick ingredients are coal gangue, clay, fly ash and other stone materials. This formula has the problems of poor thermal conductivity and thermal insulation effect of checker bricks, and checker bricks using the above raw materials will also ...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that most of the existing checker brick ingredients are coal gangue, clay, fly ash and other stone materials, this formula has poor heat conduction effect and poor heat preservation effect of the checker brick, and the grid brick of the above raw materials is used Bricks will also explode during sintering, and the sintering loss is relatively large, and the existing billet making process of checker bricks is roughly the collection of raw materials, crushing of stones, mixing of raw materials, pressing and molding, natural drying, and then sintering in kilns. In this process, the stone crushing will directly crush the raw materials, but the water
