How To Exert The Best Thermal Insulation Effect Of Fire Clay Bricks?

Date:2016-01-04 16:33 | From:Zhengzhou Sunrise Refractory | Author:admin
Although lightweight fire clay bricks have good physical and chemical properties, bad effect will be occurred if it can’t be appropriate used. So how to exert the best thermal insulation effect when using fire clay bricks?

First of all, it should be clear that lightweight fire clay bricks can exert its best thermal insulation effect only at the maximum allowable temperature conditions. So select the fire clay bricks reasonably according to the structure characteristics and working conditions and requirements for the service life of brick. For example in a reflex furnace, furnace lining is only constructed by heavy refractory brick because the lining is always eroded by furnace slag and burned by fire, and lightweight bricks bear this kind of environment at all. General insulation material is applied to outer surface of the furnace wall, continuous operation furnace, the external insulation is more reasonable, and heavy refractory bricks are used in working lining, lightweight bricks are used in non-working layer which can reduce the heat loss. Reasonable collocation also guarantees the strength of the furnace. In some non-melting furnace, all of the furnace can use lightweight clay bricks, and the effect is also very good.

Therefore, light fire clay bricks general use in the non-working layer and using effect will be very good, and it is not very suitable for working layer, because it cannot bear high temperature and erosion.
