Abstract

The invention discloses an anchoring brick. The anchoring brick comprises a main material and a bonding agent, wherein the main material comprises aggregates and power; the aggregates comprise the following components in parts by weight: 10 to 15 parts of 3 to 5mm alumina granules, 25 to 35 parts of 1 to 3mm alumina granules, 5 to 15 parts of 0 to 1mm alumina granules, and 5 to 15 parts of kyanite; the powder comprises the following components in parts by weight: 5 to 10 parts of combined clay powder, 15 to 25 parts of alumina pulverized clinker, and 15 to 25 parts of alumina raw powder; the bonding agent comprises the following components in parts by weight: 0.3 to 0.8 part of calcium lignosulphonate, and 0.1 to 0.3 part of yellow dextrin. The anchoring brick has the beneficial effects that the anchoring brick produced through the formula has higher refractoriness under load and thermal shock resistance capacity, and ensures that the service life of an industrial furnace is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to an anchor brick. Background technique [0002] Compared with unfired products and unshaped refractory materials, the thermal stability of fired products is very poor. With the technological progress of new kilns, the requirements for thermal stability of fired products are very strict. Therefore, thermal stability has become a The bottleneck of the development of fired products. For the anchor brick, it is used as an anchor to connect and fix the working layer and the insulation layer during use, and must maintain a high strength at high temperatures. In addition, the kilns used in most cases work intermittently, and they have to withstand repeated temperature changes during use. Therefore, the traditional production process is improved to improve the thermal stability and thermal shock resistance of the fired anchor bricks, which can significantly prolong the produ...
