The heat preservation of kiln furnace can use heat preservation brick or heat preservation is pouring makings undertake. Both has a characteristic, specific use which kinds of insulation material to need to undertake choosing according to actual condition.
Heat preservation brick is a kind of common insulation material, it has the following characteristic: Coefficient of thermal conductivity is small, heat proof quality is good; High temperature resistant, corrosion resistance can be strong; Install it is convenient, easy to safeguard. Nevertheless, heat preservation brick also has a few drawback, for example: Cost is higher; Secure not firm, suffer the element effect such as mechanical concussion easily.
Heat preservation is pouring makings criterion is the insulation material with a kind of stronger liquidity, it has the following characteristic: Construction is convenient, but the basis needs aleatoric modelling; Fixed and firm, be able to bear or endure mechanical concussion sex is strong; Cost is relatively inferior. Nevertheless, heat preservation is pouring makings also have a few drawback, for example: Coefficient of thermal conductivity is taller, heat proof quality is opposite poorer; High temperature resistant, corrosion resistance can be inferior to heat preservation brick. Accordingly, the use environment that chooses furnace of kiln of basis of insulation material need, heat preservation asks and the element such as economic benefits has integrated consideration, choose suitable insulation material to undertake construction. In applying actually, also furnace of a few kiln uses heat preservation brick and heat preservation pouring the kind that makings photograph ties has thermal insulation, in order to fill the characteristic with minute of both play.
Which kinds of material does kiln furnace heat preservation pick appropriate? Insulation material needs the kiln furnace that the choice suits to consider many factors integratedly, requirement of the use environment of the furnace that be like kiln, heat preservation, economic benefits.
Insulation material basically includes common kiln stove heat preservation brick, warming plate, heat preservation is pouring makings, fireproof fiber. Specific choice which kinds of insulation material, can consider from the following respects:
1, the use environment of kiln furnace: The use environment of kiln furnace is the main factor that chooses insulation material, for example, the element such as high temperature, caustic gas, mechanical concussion is met produce an effect to insulation material. If the use environment of kiln furnace is harsher, need chooses to have the insulation material of the function such as caustic of high temperature resistant, anti-corrosive, wear-resisting.
2, heat preservation requirement: The heat preservation requirement of kiln furnace also is the main factor that chooses insulation material, different kiln furnace asks to go up to be put possibly in difference in heat preservation. For example, certain kiln furnace needs heat preservation effect good, coefficient of thermal conductivity is low, need chooses the insulation material with superior heat proof quality; Certain kiln furnace needs heat preservation effect good, modelling is agile, can choose heat preservation pouring makings.
3, economic benefits: Still need to consider economic benefits factor when choosing insulation material, the price that includes insulation material, construction is difficult easy degree, service life. Need falls in the premise that assures heat preservation result, consider economic benefits factor, alternative price compares tall insulation material.
The place on put together is narrated, insulation material needs the kiln furnace that the choice suits to consider many factors integratedly, need falls in the premise that assures heat preservation result, the real case that joins kiln furnace undertakes choosing.
