Main Technical Indicators of High Alumina Refractory Ball

图片
The technical Indicators of high-alumina refractory ball is the main reference basis in the procurement process, which determines the quality of the refractory ball. There are 7 main technical indicators of high alumina refractory ball , which are Al2O3 content, Fe2O3 content, bulk density, apparent porosity, room temperature compressive strength, load softening temperature, and thermal shock stability. The following is the detailed technical indicators of high alumina refractory ball. High Alumina Refractory Ball 1. Al2O3 Content The popular point of Al2O3 content is the content of aluminum oxide in the raw materials of refractory balls. The aluminum content determines the level of other properties. Therefore, it is the main performance index of refractory balls. There are four main types of high alumina refractory balls based on aluminum content: Special grade high-aluminum ball, RQA-80 with 80% aluminum content; Grade I high aluminum ball, RQA-75 with 75% aluminum con...

Main Difference between Insulation Bricks and Refractory Bricks

The main difference between insulation bricks and refractory brick s. Insulation bricks and refractory bricks are refractory materials and insulation materials commonly used in furnaces and various high-temperature equipment. Although they are all brick refractory materials, their performance and use are completely different. Today I will introduce the main functions and differences between the two. Cheap High Alumina Refractory Bricks In RS Company Insulation bricks are mainly used to keep heat and reduce heat loss. Generally, insulation bricks do not directly contact the flame. Refractory bricks can generally directly contact the flame or hot solution, and can withstand the flame of the flame, the erosion and abrasion of the solution. The main differences between insulation bricks and refractory bricks are as follows: 1. Thermal insulation performance: The thermal conductivity of thermal insulation bricks is generally 0.2-0.4 (average temperature 350 ± 25 ° C) w / mk,...

Insulation Mechanism of Lightweight Insulating Refractory Bricks

Conception: Heat is a kind of energy, which is closely related to the movement of the molecules, atoms, and electrons that make up the material. The thermal phenomenon of all substances is the result of the collision, transfer and movement of particles inside the substance. Lightweight Insulating Refractory Bricks Uses In thermal industries such as kilns, the loss of energy due to heat transfer becomes extremely apparent. The temperature difference between the inside and outside of the kiln is above 800 ° C. The role of the lightweight insulating refractory bricks are to slow down the heat transfer process through the internal holes, thereby achieving the effect of heat insulation. Generally, lightweight insulating refractory bricks materials are mainly composed of a solid phase and a gas phase, so the overall heat transfer process of the material consists of heat transfer between the solid phase, heat transfer between the solid phase and the gas phase, convection between ...
