Audited Supplier Silicon bricks is the refractory products with SiO2 content of more than 93%.The crystalline phases are lepidoquartz and cristobalite.
Silicon bricks for coke ovens include raw materials and auxiliary materials, expressed by weight ratio, the raw material formula contains 200-250 pieces of silica coarse powder, 330-380 pieces of silica powder, 80-130 pieces of silica fine powder, 80-120 pieces of residual silica brick as clinker powder, the silica coarse powder is composed of three parts, of which the particle size range between 3 Imm silica accounted for 64%-74%. 10. 088mm between the silica pair %-; 34%, less than 0.088mm silica 1%-2%, the silica powder is composed of three parts, of which the particle size range between 3 Imm silica 1%-2%, between 10.088mm silica 64%-749(), less than 0.088mm silica 24%_34%, The silica fine powder is composed of two parts, wherein the particle size range is between 1.088mm and 5%-15% of the silica, less than 0.088mm of the silica 85%_95%, and the residual silica brick is composed of three parts. Among them, the particle size range between 3 Imm is 1%_ 2% silica, between 10. 088mm silica 58%-68%, less than 0. 088mm silica 30% -40%; The auxiliary materials include 1.2% of the total weight of the raw material mineralizer, 8% of the lime milk and 1% of the pulp, the mineralizer by MnA content of 25% of the manganese powder FeO content of 65% of the iron and phosphorus powder according to the ratio of 1 :1 mixed; The coarse silica powder, silica medium powder, fine powder and residual silica brick as clinker powder are added to the wet roller, and then the mineralizer is added to dry mix for 4-5 minutes, then the lime milk is added, and after rolling for 10-15 minutes, the paper pulp is added, and the mud is mixed until the mud is uniform, rolled and formed.
Features of Checker Silica Refractory Brick Various of Silica Brick for Coke Oven
1. Having a plurality of transparent cell holes parallel to the side surface, and positioning protrudes and positioning grooves located on two parallel surfaces.
2. Good volume stability, high temperature load creep performance, high density and low porosity. Modern blast furnace hot blast furnace usually adopts lattice brick regenerator structure
