What does cupola use fireproof material

What does cupola use fireproof material? Liner service life is how long, see detailed introduction please.


Cupola is equipment of smelt of a kind of high temperature, need is used can be able to bear or endure the fireproof data that gets shock of high temperature, heat-resisting. Fireproof material includes common cupola tall aluminous brick, siliceous aluminium brick, magnesia brick.
In cupola, high temperature body of heater can be expanded by ceaseless heat with systole, this raised very tall requirement to the thermal shock stability of fireproof material and wear. Accordingly, usually need uses high quality fireproof data, with assuring cupola move normally and longer service life.
Tall aluminous brick is a kind of commonly used fireproof material, it is by the alumina of tall purity and silicon simple matter passes high temperature agglomeration to be made. Tall aluminous brick has shake of good high temperature stability, heat-resisting gender, acid-proof alkaline erode wait for a characteristic, get applied extensively in the domain such as metallurgy, building materials, chemical industry, also be one of commonly used and fireproof material of cupola.
Siliceous aluminium brick is the fireproof material that one kind passes hot pressing by the siliceous aluminous powder of tall purity or hot agglomeration makes, it has good high temperature stability, heatproof shake gender and fight the characteristic such as aggressivity, also be one of fireproof material with commonly used cupola.
Magnesia brick is a kind of fireproof material that is bases with magnesian qualitative raw material, have good high temperature stability and heatproof shake sex, can use at the high temperature equipment of the domain such as metallurgy, chemical industry, also apply to the production of cupola.
Besides afore-mentioned common fireproof material, still have other fireproof data, if carborundum brick, nitrogen changes silica brick to wait, can choose right fireproof stuff according to specific use condition and requirement. When choose and using fireproof data, the working requirement that needs to consider cupola, service life and safeguard the element such as cost.
The service life of the fireproof material of cupola basically gets the influence of a variety of elements, if the temperature inside furnace, hot loop, oxidation is reductive environment, stock is characteristic wait. Usually, operate and maintain the service life that can prolong fireproof material reasonably. Normally the circumstance falls, the fireproof material service life of cupola can amount to several months to differ to several years, material service life needs to undertake evaluate and be controllinged according to actual condition.
