Description
Technical field
The present invention relates to technical field of refractory materials, particularly to a kind of anchored brick.
Background technology
Compared with not burned product, amorphous refractory, the heat stability of burnt product is very poor, along with the technological progress of novel kiln, very strict to the thermal stability requirement of burnt product, has become the bottleneck of burnt product development for this heat stability.For anchored brick, in use play the fixing working lining of connection and heat-insulation layer as anchoring piece, at high temperature have to keep higher intensity.Additionally, its kiln used, in most cases, for service intermittent, repeatedly to stand variations in temperature in using, thus improve traditional processing technology, improve heat stability and the thermal shock resistance burning till anchored brick, can significantly extend the service life of anchored brick.Current industrial kiln blowing out overhaul is owing to anchoring piece therein fracture is caused mostly.Therefore highly heatproof and shockproof, high RUL anchored brick are developed the most necessary.
Summary of the invention
The purpose of the present invention is that and overcomes above-mentioned deficiency, it is provided that the anchored brick that a kind of heat stability is high, shock resistance is strong.
For reaching above-mentioned purpose, the present invention implements according to techniques below scheme:
A kind of anchored brick, including major ingredient and bonding agent, described major ingredient includes aggregate and powder, described aggregate is made up of the component of following parts by weight: alumina particle material 10-15 part of 3-5mm, alumina particle material 25-35 part of 1-3mm, alumina particle material 5-15 part of 0-1mm, kyanite 5-15 part of 0.5-1mm；Described powder is made up of the component of following parts by weight: bonding clay powder 5-10 part, bauxite clinker powder 15-25 part, Alumina fecula 15-25 part；Described bonding agent is made up of the component of following parts by weight: calcium lignosulfonate 0.3-0.8 part, yellow starch gum 0.1-0.3 part.
As the improvement to technique scheme, anchored brick is made up of the component of following parts by weight: 15 parts of 3-5mm alumina particle material, 30 parts of 1-3mm alumina particle material, 5 parts of 0-1mm alumina particle material, the kyanite of 0.5-1mm 10 parts, 5 parts of bonding clay powder, 20 parts of bauxite clinker powder, Alumina fecula 15 parts, calcium lignosulfonate 0.4 part, yellow starch gum 0.1 part.
Compared with prior art, the invention has the beneficial effects as follows: the anchored brick produced with this formula has stronger refractoriness under load and thermal shock resistance so that the life-span of industrial furnace is greatly improved.
