Refractory brick manufacturer must have own innovations to become International
[Release time:2024-10-16 14:43:34] [Reading times:54]
 

Developed refractory materials, due to the use of different raw materials, produce refractory bricks with inferior physical and chemical properties compared to refractory bricks in other regions. Developed refractory materials have nearly 20 years of technical experience in producing refractory bricks, with professional technicians and multiple cooperative logistics companies, saving customers some shipping costs. Our technicians will provide on-site technical support and usage methods. All of these make customers feel very confident when purchasing our products.


Refractory bricks are abbreviated as fire bricks. Refractory materials made by firing refractory clay or other refractory materials. Light yellow or brownish in color. Mainly used for building smelting furnaces, capable of withstanding high temperatures ranging from 1580 ℃ to 1770 ℃. Also known as fire bricks. Refractory materials with a certain shape and size. According to the preparation process, it can be divided into fired bricks, unburned bricks, electric melting bricks (cast bricks), and refractory insulation bricks; According to shape and size, it can be divided into standard bricks, ordinary bricks, special bricks, etc. High temperature building materials and structural materials that can be used as building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures. For example, refractory clay bricks, high alumina bricks, silica bricks, magnesia bricks, etc.


When purchasing high-quality refractory bricks, do not blindly choose. You should start from the following aspects:
1. Volume density: unit volume weight. A high density indicates good density, which may lead to high strength, but may also result in a high thermal conductivity.
2. Visible porosity: No specific requirements have been made, but as a manufacturer, it is necessary to strictly control visible porosity.
3. Load softening temperature: also known as the temperature at which high-temperature loads begin to deform. This parameter is important and indicates the material's ability to resist high temperatures.
4. Thermal shock resistance: the ability to withstand rapid temperature changes without being damaged.
5. Compressive strength: the maximum pressure capacity that can withstand (at room temperature).
6. Flexural strength: the ability to withstand shear pressure.
7. Linear rate of change: also known as re burning line change or residual line change, refers to the change in volume expansion and contraction during each equivalent temperature change.
8. Thermal conductivity: Under the condition of unit temperature gradient, the heat flux rate per unit area of the material is related to the porosity.
9. Impact resistance: No need to explain, good impact resistance means long service life.
10. Slag resistance: the ability to resist the erosion of slag at high temperatures without being damaged.
