Product Description

Firebrick is referred to as firebrick. A refractory made of fireclay or other refractory materials. Pale yellow or brownish. It is mainly used for laying smelting furnace, which can withstand high temperature of 1,580 ºC -1,770 ºC. Also known as firebrick. Refractory material of a certain shape and size. According to the preparation process, it can be divided into fired brick, unfired brick, electric fused brick (fused cast brick), refractory heat insulation brick; According to the shape and size can be divided into standard brick, ordinary brick, special type brick and so on. It can be used as high temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures. Such as refractory clay brick, high aluminum brick, silicon brick, magnesium brick and so on.

Characteristic:
1, Chemical composition: the main composition determines the quality and characteristics of the refractory refractory brick
2, Volume density: unit volume weight, high density, indicating good density, strength may be high, but the thermal conductivity may be large
3, Apparent porosity: no specific requirements, but as a manufacturer must strictly control the apparent porosity.
4, Load softening temperature: also known as high temperature load deformation temperature, this parameter is very important, marking the resistance of high temperature resistance of the material
5, Thermal shock performance: resistance to rapid changes in temperature without being destroyed
6, Compressive strength: withstand the maximum pressure capacity (normal temperature)
7, Bending strength: the ability to withstand shear pressure 8, linear change rate: Also called reburn line change or residual line change, refers to the change in volume expansion and contraction every time the same temperature change, if every expansion and contraction is the same, we define such a linear change rate of 0

The properties of refractory raw materials mainly depend on the mineral composition and particle composition of raw materials, and are closely related to the manufacturing process of refractory materials. Such properties are mainly particle size and particle size distribution, fineness and specific surface area, plasticity and adhesion, drying shrinkage and firing shrinkage, sintering temperature and sintering range

The plasticity of the clay:

Plasticity grade	Plasticity index %	Plasticity index /kg·cm
Strong plasticity	>15	>3.6
Medium plasticity	>15	2.5~3.6
Weakly plastic	1~7	<2.5
non-plastic	<1	-
