Refractory brick is a type of building material brick whose properties are as "fire-resistant" as its name. Refractory bricks are not common in our lives, but they are found in buildings that are related to our lives, such as house construction, coal stoves, etc. Do you understand the specifications of refractory bricks ? In addition to the dry building masters who know the specifications of the firebricks , it must be understood that there are fewer people? The following Xiaobian brings you together to understand the specifications of firebrick and firebrick .
Refractory bricks are referred to as fire bricks for short. They are refractories made of fire-resistant clay or other fire-resistant raw materials. They are light yellow or brownish. It is mainly used for smelting furnaces and can withstand high temperatures of 1,580Â°C to 1,770Â°C. It can be used as high-temperature building materials and structural materials for building kilns and various thermal equipments, and can withstand various physical and chemical changes and mechanical effects at high temperatures.
There are two types of firebricks, one is a shaped refractory, and the other is an unshaped refractory. Refractory bricks are mainly used to build high-temperature building materials and kilns for various thermal equipment. Its kind mainly depends on shape and size to distinguish. The specification and size of refractory bricks are as follows:Dimensions of straight firebricks are represented by A Ã— B Ã— C (unit: mm) Sizes of wedge firebricks are represented by A Ã— (C/D) Ã— B (unit: mm) Arch foot bricks are sized (L/C) Ã— (A/B) Ã— (E/D) Representation (Unit: mm)
Therefore, to determine the size of the firebrick and the size of the firebrick, it is necessary to determine the characteristics of the firebrick and its representation.
Firebrick attribute characteristics
1. Chemical composition: The main components determine the quality and characteristics of the refractory
2, bulk density: unit volume weight, high density, indicating that the compactness is good, the strength may be high, but the thermal conductivity may be large refractory brick
3, apparent porosity: no specific requirements, but as a manufacturer must strictly control the air vents.
4, the load softening temperature: also called high temperature load deformation temperature, this parameter is very important, marking material resistance to high temperature resistance
5, thermal shock resistance: the ability to resist sudden changes in temperature without being destroyed
6, compressive strength: withstand (normal temperature) maximum pressure capacity
7, bending strength: ability to withstand shear pressure
8, linear rate of change: also known as re-line change or called the residual line change, refers to the same change in the volume of the expansion and contraction of the temperature change, if each expansion and contraction, we define such a linear rate of change is 0
Xiao Bian concludes: Nowadays, brick material is the most important material for our construction industry. The specification of refractory bricks is determined according to the characteristics and representation of firebricks. Therefore, the specifications of firebricks produced by each manufacturer are not the same. Xiao Bian Can only give you a brief description of his expression and features, specific specifications can consult the relevant store. More information about the renovation can focus on this site, more exciting content waiting for you to see.
