Heat preservation brick is the result that use what principle and achieves heat preservation

Heat preservation brick is the functional material in firebrick, with gross the action such as heat insolation of light, heat preservation, managing the sources of energy serves to be versed in at heat equipment. The result that what principle use and what principle use and achieves heat preservation is heat preservation brick? You Rongcheng is able to bear or endure below capable person is young make up make detailed introduction for everybody.



Brick of light qualitative heat preservation is in firebrick the person is added in making after certain and special material firing. Its porosity is one times taller than common firebrick, firebrick density compares coessential firebrick small 0.5—7 times. Coefficient of thermal conductivity is small, because this can use the thermal insulation that serves as furnace or liner, in order to reduce hot loss; To the furnace that intermittent type works, boiler setting accumulation of heat and heat loss due to radiation can decrease 80% . Of the firebrick with brick of light qualitative heat preservation and general and same qualitative capable person fireproof degree differ not quite, loading softening point criterion slightly low. If light qualitative brick is long-term when be used below high temperature, can continue agglomeration break systole, cause crackle to be destroyed even. So majority pledges the brick has many to use the issue of temperature gently, if pledge gently argillaceous brick is tall have 1150 ℃ only, light qualitative tall aluminous brick uses temperature not to exceed 1350 ℃ , pledge Mo Laishi brick uses temperature not to exceed 1500 ℃ gently, light qualitative silica brick can amount to 1600 ℃ . The problem with because light qualitative silica brick is nonexistent contractive high temperature, volume is steadier, accordingly can build by laying bricks or stones of in order to builds the liner that enrages a contact with furnace directly. The result that what principle use and what principle use and achieves heat preservation is heat preservation brick? Heat preservation brick is to use a brick inside distributing even stoma, can reduce caloric very well to deliver, make caloric sends out conduct speed to decelerate, have effect of heat preservation heat insolation thereby. Because pledge heat preservation brick has density gently small, porosity tall, thermal conductance sex of small, heat preservation is good and the characteristic such as the compression strength with have particular, already won wide application on heat treatment equipment. What does commonner heat preservation brick have? Commonner have bleach brick of bead brick, light qualitative clay, light qualitative tall aluminous brick (tall aluminium gets together brick of light heat preservation) , light qualitative Molaishi brick (Molaishi gets together light brick) , light qualitative silica brick is waited a moment. Above is about " heat preservation brick is the result that use what principle and achieves heat preservation " relevant introducing, hope to be helped somewhat to everybody, major of flourish Cheng Naicai produces brick of liner of furnace of high temperature kiln to expect, what ensured hot project facilities effectively is normal move, reduced prediction of a person's luck in a given year of quantity of heat, can let control of equipment appearance temperature be in 300 degrees the following, 100 degrees the following, 75 degrees the following, raised utilization rate effectively, promote a product quality at the same time. Welcome everybody the incoming telegram seeks advice and choose and buy, flourish Cheng Naicai is dedicated be able to bear or endure material territory is old, be able to bear or endure to make home material is large produce a business and try hard ceaselessly.
