Regenerator of furnace of kiln of float law glass needs to use fireproof material to resist normally high temperature condition, maintain vitreous production and treatment temperature. These regenerator are crucial component, because of them stored heat is measured, maintain constant temperature, so that be obtained in vitreous production process,heat equably and cool.
It is the ingredient of a few serious considerations that uses fireproof data in regenerator of furnace of kiln of float law glass below:
The type of fireproof material: Regenerator needs to use height normally fireproof firebrick or fireproof and pouring makings, in order to resist high temperature. These material should have good thermal stability, counteractive heat expands and can contract.
The choice of fireproof material: When choosing fireproof material, frequency of temperature of need consideration operation, hot loop and the interaction that put the chemical matter that be in with the likelihood in glass. The fireproof material of different type suits different application.
Safeguard and durable sex: The fireproof material in regenerator may be experienced heat expands and cold shrink, this meeting generates constant pressure to material. Accordingly, the fireproof material that chooses to have property of good and heatproof shake is very important, in order to reduce the risk of craze and attaint.
Install and safeguard: Install and safeguard goodly regularly effective to ensuring the fireproof material inside regenerator lasts special and important. Safeguard can include agglomeration, repair or change the fireproof material of damage.
Regenerator basically introduces product of firebrick of series of MgO-Al2O3, MgO-Cr2O2, MgO-SiO2 with firebrick, its product has brick of direct union magnesia brick, magnalium, direct couple magnesian chromic brick and magnesian olivine the brick. These products basically apply in regenerator to make checker brick use. Go up at what regenerator is in, mid checker brick, at air and gas working environment, oxidation is reductive repeatedly, makings of the change of high temperature temperature, pink flies medicinal powder, the condensation of alkaline steam, such environment, can use alkalescent and fireproof material to make checker brick. In addition, regenerator still has use tall aluminous brick.
Vitreous kiln regenerator uses the sort of fireproof material:
① regenerator carries Xuan on the head. Regenerator Xuan carries appropriate on the head to use high grade silica brick, xuan carries heat preservation on the head to be able to use the form with as big as fused ministry identical Xuan and material to pledge. ② regenerator wall. The regenerator wall that includes midfeather inside, in same standard paragraph the structure inside and material ask character identical. ③ regenerator checker. Set upright the checker to regenerator from on to because what suffer,fall temperature is amiable atmosphere is different, cent is a few section, the checker brick that each paragraphs of checker pledges with different capable person piles up build by laying bricks or stones. Xuan of ④ regenerator fire bars. Regenerator checker is build by laying bricks or stones of agglomeration material code completely, brick of make level of Xuan of its fire bars can use brick of clay of excel in low porosity.
As a whole, the fireproof material of regenerator is acting important role in process of production of float law glass, because they conduce to the high temperature condition that maintains stability, ensure manufacturing quality and efficiency. Choosing relevant fireproof data to undertake be maintenanced goodly is to ensure kiln furnace runs successful crucial factor.
