Attentions During The Using Of Fire Clay Bricks

Date:2015-11-05 14:48 | From:Zhengzhou Sunrise Refractory | Author:admin
Fire clay bricks have the thermal properties of heat capacity, thermal expansion and thermal conductivity which are the basis to measure the ability of light clay brick to adapt to the heat process. Heat capacity refers to the absorption heat while the material temperature rises 1000 ℃. Thermal expansion is a property that the volume of material increases with the increasing of temperature. Thermal conductivity is the speed of temperature of the material transferring around when in the process of heating or cooling.

According to the properties and characteristics of fire clay bricks, below three problems should be pay attention during the using process.

1. The slag resistance of fire clay bricks is poor, so it can’t contact with slag and liquid directly, and also can’t directly contact the high temperature dust, otherwise, irreversible damage will be caused to the brick body.

2. Fire clay bricks have a large shrinkage, so the end-use temperature should be 50~100℃ lower than the sintering temperature.

3. The mechanical strength and wear resistance of fire clay bricks are poor, so it can't bear strong pressure which means not overload and over weight in order to prevent the brick body fracturing. It can't also be used in the parts of frequently opening and violent vibration. So the layout of construction should be reasonable to prevent the expansion of crushing.

Obviously, the performance of fire clay bricks is not good at all aspects, so only if fully understanding its overall performance that can ensure the performance of fire clay bricks during the using process.
