Introduction of casting material
The pouring material is also called the refractory casting material, which is made from the refractory material by adding a certain amount of binder. With high fluidity, the refractory material is suitable to be formed by casting method.
Compared with other unshaped refractory material, binder and higher moisture content, liquidity better, and therefore not stereotypes refractory material has wide application scope, under the conditions of use of the material and binder to be selected. Can be directly cast into the use of the lining, and can be used as a method of pouring or earthquake in the use of prefabricated blocks.
Classification of refractory casting materials
Refractory materials are divided into refractory materials and refractory materials. Unshaped refractory castable is composed of a variety of aggregate or aggregate and one or more viscous agent and mixed powder particles and must be used and a or a plurality of liquid with stirring evenly, with strong liquidity and plasticity.
Type of casting material
According to the porosity ratio, binder and aggregate variety. In practice, the use of temperature or functional features are often used to classify.
According to the porosity ratio: there are dense refractory pouring material and porosity rate of not less than 45% of the heat insulation refractory burning note two kinds of.
According to the bond points: there is a combination of water hardness, chemical binding, condensation combined with refractory pouring material.
Hard binding casting material at room temperature condensation hardening and through hydration and hardening, the main varieties of Portland cement, ordinary calcium aluminate cement, pure calcium aluminate cement, electric melting pure calcium aluminate cement casting material, etc.. Chemical combination of casting materials at room temperature generally through the addition of hardening agent to form a chemical reaction and hardening, the main varieties of water glass, aluminum sulfate, phosphate casting materials, etc.. In the process of sintering, the aggregate and the casting materials are hardened by sintering, the main varieties are clay casting materials, etc..
According to the refractory aggregate: clay aggregate (Al2O3 30% ~ 45%), high alumina (Al2O3%26ge; 45%) aggregate, siliceous aggregate (SiO2%26ge; 85%, Al2O3%26lt 10%) alkaline aggregate (magnesite and dolomite), a special aggregate carbon, carbides, spinel, zircon, nitride and insulation aggregate (perlite, vermiculite, ceramsite, cenosphere, light sand brick, porous chamotte, alumina hollow ball).
Construction of pouring material
All the raw material from China big steel mills, are unused steel products spare material and leftover material , no oil, no protective film, no impurities, which are high quality raw material for intermediate frequency furnace, 20 and 30 kg of small packaging are more suitable for small intermedium frequency furnace,and it can be directly converted into molten steel. We can provide the list and data of each transaction tested by NITON or Olympus spectral analyzer, and guarantee the detection rate of the product to be 100%

We customize various printed nameplate, danger sign plate according to specifications from customers. Material can be plastic or aluminum.
Name: aluminum die casting, zinc die casting products Material: aluminum, zinc Can be customized
These cast iron skulls are a by-product derived from the cast iron foundries. The byproduct is a ferrous by-product which can be utilised in an electric arc furnace to produce crude steel. Physical Description On visual inspection, it appears to be made up of irregular shapes. The material is separated by magnet and screener. Packing: Loose in container Loading: in 20 Container For further information, please feel free to contact us.
We customize various zinc die casting parts. Complex shapes can be formed by zinc die casting technology to avoid multiple assembly and welding process, besides the surface of zinc die casting parts is good, nearly no need secondary process. The production cost can be lowered to a maximum degree. Such parts are light, but they have excellent strength and rigidity, are widely used in electronic, auto and aerospace field. In addition, such material is recyclable, and environmentally friendly.
