Refractory Molded Brick
According to the different composition of refractory brick, refractory molded bricks can be divided into five categories: Silica alumina refractory molded brick;Basic series of refractory molded bricks;Carbon containing refractory molded brick;zirconium containing refractory molded brick;insulating refractory molded brick.
Any furnace is not only made of a refractory brick, but needs to be used with different refractory bricks.Gongyi Jinniu refractory factory mainly produces refractory molded bricks for nonferrous metal industry.
1.Silica alumina refractory molded brick
Silica refractory molded brick
Silica refractory molded brick refers to the SiO2 content reached more than 93% of the refractory molded brick, who is the main type of acid refractory molded brick.
Clay refractory molded brick
Clay refractory molded brick is mainly composed of mullite (25% ~ 50%), glass phase (25% ~ 60%) and cristobalite and quartz (up to 30%) component.Usually hard clay as raw material, pre calcined mature material, and then with soft clay, semi dry or plastic molding, the temperature of 1300 ~ 1400 C fired clay brick products,who can also be added a small amount of water glass, cement and other binders made of non burning products and amorphous materials
High alumina refractory molded brick
High alumina refractory molded brick is composed of mineral corundum, mullite and glass phase, the content of al2o3/ depends on the SiO2 ratio and the type and amount of impurities and according to the content of Al2O3 refractory brick classification.The raw material for high alumina bauxite and sillimanite natural ore, also adding fused corundum, sintered alumina, mullite, alumina and clay and calcined clinker according to different proportion.It is with the sintering production process.
Corundum refractory molded brick
Corundum refractory molded brick refers to the Al2O3 content of not less than 90%, the main phase of a refractory brick with corundum as, can be divided into sintered corundum brick and fused corundum brick. Alkaline refractory brick. Alkaline refractory brick refers to alkaline oxides such as refractory products Mg0 and Cao as the main component.
2.Basic series of refractory molded bricks
Magnesia refractory molded bricks
Magnesia refractory molded bricks, refers to the brucite as raw materials, mainly to periclase phase, the content of MgO in refractory brick more than 85% ~ 80%.The main products of magnesite refractory molded bricks is alkaline refractory brick, high refractoriness, has good resistance to alkaline slag is a kind of important high refractory brick.
Magnesia olivine refractory molded bricks
Magnesia olivine refractory molded bricks, with 2MgO SiO2 as a main component of the refractory brick. There is good effect in copper smelting furnace.
3.Carbon containing refractory molded brick
Carbon containing refractory brick is a kind of refractory brick made of carbon or carbon compound.
Carbon refractory molded brick
Carbon refractory molded brick, with carbonaceous materials as the main raw material, made of the amount of binder of the thermostable neutral refractory products.Carbon refractory brick masonry is widely used in the bottom of the hearth, bosh and lower stack. Can improve the continuous working time of the blast furnace, prolong the service life of carbon brick. It is also widely used in non-ferrous metal smelting furnace.
Graphite refractory products
Graphite refractory products are made of natural graphite as raw material and clay as binder. The most widely used is the graphite crucible which is used for smelting copper metal.
Carborundum refractory molded brick
Silicon carbide refractory molded brick are made of silicon carbide (SIC) as the raw material for the production of advanced refractories.Carborundum refractory molded brick has the advantages of good abrasion resistance and corrosion resistance, high temperature strength, high thermal conductivity, small coefficient of linear expansion and good thermal shock resistance.In non-ferrous metals (zinc, copper, aluminum, etc.) smelting, a large number of used for distillation, distillation tray, the wall of the electrolytic tank, molten metal pipe, suction pump and smelting metal crucible.
Gongyi Taurus Refractory Material Factory is a professional refractory materials manufacturers and refractory materials suppliers,mainly supply Unshaped Refractories,Silicon Carbide Refractory Castable,Castable Refractory Cement,Pouring Material,Castable Refractory Concrete,Silica Ramming Mass etc. series of refractory materials products, sincerely welcome everyone to visit.
