Manage of hollow ball brick changes alumina index

Alumina is hollow ball brick - 99 alumina are hollow ball brick - high pure alumina is hollow ball brick is a kind of new-style high temperature heat-insulating material, it is to use industrial alumina to blow what make and become in the fusion in electric stove, brilliant for A-Al2O3 microcrystalline body. With alumina hollow ball gives priority to body, can make all sorts of form product, use temperature 1800 ℃ , products machinery intensity is high, those who be general small qualitative products is multiple, and 1/2 what bulk density is corundum goods only. High temperature, superhigh temperature kiln waits in electric induction furnace of reaction furnace of industry of furnace of petrifaction industry aerification, carbon black, metallurgical industry get applied extensively on furnace, obtained well-content energy-saving result.

1, alumina is hollow ball brick - 99 alumina are hollow ball brick - high pure hollow ball brick uses alumina temperature is high:

Can amount to 1750 degrees of above, thermal stability is good. Ratio of the heavy change that burn a line is small, use longer.

2, alumina is hollow ball brick - 99 alumina are hollow ball brick - high pure hollow ball brick optimizes alumina structure, reduce weight of body of heater:

Use now high temperature resistant material belongs to density of bulk of heavy qualitative brick to be 2.6-3.0g/cm, and hollow ball brick has alumina only 1.1~1.5g/cm, same one stere bulk, hollow ball brick can reduce use alumina 1.1-1.9 ton weight.

3, alumina is hollow ball brick - 99 alumina are hollow ball brick - high pure alumina is hollow ball brick is managing material:

Reach same use temperature, if use heavy qualitative brick its price and alumina are hollow ball brick price comparatives, and still need quite considerable heat-insulation layer fireproof material. If use alumina hollow ball brick, every stere can save 1.1-1.9 ton the use quantity of heavy qualitative brick, can save the fireproof insulation material of 80% more.

4, alumina is hollow ball brick - 99 alumina are hollow ball brick - high pure hollow ball brick saves alumina the sources of energy:

Hollow ball has alumina apparent heat preservation is characteristic, coefficient of thermal conductivity is low, can rise

Very good heat preservation effect, reduce quantity of heat to send out, improve thermal efficiency, have the objective of managing the sources of energy thereby. Energy-saving effect can amount to 30% above.
