Our zircon brick series products included the alpha Al2O3, partial stability of zirconium dioxide and zirconium material such as alumina clinker as raw material, through mixing, molding, drying, the shuttle kiln high temperature burn becomes.The crystal structure and dense zircon brick products, bulk density, high capacity big, high mechanical strength at room temperature and high temperature, good thermal shock stability performance, reheat shrinkage and high temperature creep decrescent, and high chemical stability and resistance to erosion features such as alkaline medium.Dense zircon brick is mainly used in sodium - calcium glass kiln middle brick, brick arch foot, etc;Containing zirconium brick is mainly used in large glass kiln, tube furnace melting pool, regenerative chamber wall brick kiln and chemical industry, metallurgical industry solution erosion area.Appearance size, physical and chemical index of the products, service life have reached or exceed the level of similar products at home and abroad.

Our refractory plant is committed to high-end special refractory materials research, development and production, the current main products are: high purity corundum products, corundum mullite product adoprs electrocast refractories.through, mullite corundum products products, light corundum, alumina bubble products, corundum mullite product adoprs electrocast refractories.through pure zircon, zircon brick, brick, zircon brick, dense zircon brick, ordinary zirconium, zirconium corundum brick stone brick, zirconium mullite zirconium in brick, brick, zirconia hollow brick, chrome brick products, all kinds of shaped refractory material.Gongyi city god nantes kinds of refractory plant adhere to the quality strives for the survival, constantly improve the technological content of products and technology level, continuously introduce new products, pursuing with the right price, high quality products to provide customers with satisfactory and efficient service!

 

 

Q:What's the size of the fused zirconia corundum refractories for glass furnace? What are the main kilns? How much is the dosage?
The fused zirconia corundum brick is made up of 30% ~ 41% zirconia two in the alumina burden. The main mineral compositions are corundum, zircon and glass phase. The main varieties are fused (or cast) zirconium corundum brick (also known as AZS casting brick) and sintered zirconia corundum brick. Generally speaking, zircon corundum brick means sintered zirconia corundum brick. It is made from alpha -Al2O3, partially stabilized zirconia and zircon corundum clinker, which is prepared by proportioning and molding at 1700~1750 DEG C and then sintered at two. The sintered zirconium corundum brick has a strong resistance to molten glass, and its thermal shock resistance is stronger than that of fused zirconia corundum brick. It is mainly used as lining of glass furnace and induction furnace, as well as steel rolling furnace, slide rail, etc..
Q:How to improve the induction furnace campaign, from the promotion of refractory life start
According to the workpiece, choose the appropriate hardware castable, corundum brick or refractory bricks, etc.
Q:What are the refractory materials?
Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.
Q:What does refractory consist of?
According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
Q:What's the jade stove for?
Corundum furnace for corundum smelting furnace, usually electric arc furnace for smelting dense corundum, corundum, white corundum, zirconia corundum, magnesia, magnesium aluminum spinel and fused refractory materials, professional design, Xi'an Xinda furnace engineering limited liability company manufacturing corundum furnace.
Q:Can the fire clay be reused?
According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, ordinary brick, specific rotation. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature.
Q:What are the main constituents of refractory bricks?
Clay brick and clay brick are mainly composed of mullite (25% ~ 50%), glass phase (25% ~ 60%) and square quartz and quartz (up to 30%). Usually with hard clay as raw material, pre calcined mature material, and then with soft clay, semi dry or plastic molding, the temperature at 1300~1400 C fired clay brick products. Can also be added a small amount of water, glass, cement and other binders to make non burning products and amorphous materials. It is a refractory brick commonly used in blast furnaces, hot blast furnaces, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory bricks.
Q:What are the advantages of refractories?
The castable refractory is a refractory product with a certain shape after being melted at high temperature by a certain method. Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.
Q:What refractory materials are used in industrial furnaces?
Economically, it is necessary to do technical and economic analysis when selecting materials reasonably. Under the premise that the technical indexes agree with the working conditions of the furnace, the refractory materials with low quoted price should be used as much as possible, without high-grade finished products. To think about whether to make self (such as irrigation, refractory concrete) as far as possible to repair old.
Q:Which is faster for heat transfer between corundum bricks and high alumina bricks?
For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
