Refractory Bricks Features: High temperature stability: Refractory bricks can maintain their shape and performance at extremely high temperatures and will not melt or deform easily. Mechanical strength: With high compressive strength and flexural strength, they are suitable for parts that need to bear weight or structural support. Chemical corrosion resistance: They have a certain tolerance […]

Silicon carbide (SiC), also known as silicon carbide or corundum, is a compound composed of silicon and carbon. Here are some key facts about silicon carbide: Structure: Silicon carbide has a variety of crystal structures, the most common of which are α-SiC and β-SiC. α-SiC has a hexagonal structure, while β-SiC has a cubic structure. […]

1. Preparation before construction Material storage: Refractory plastic cannot be piled in the open air and should be stored in a cool warehouse. If the ambient temperature is below 10℃, cold protection measures need to be taken. Equipment commissioning: Install the forced mixer in place and test run normally. Cleaning the site: Before construction, the […]

Refractory cement and refractory mortar are two different building materials that differ in composition, use, and performance. The following are their main differences: Refractory cement Refractory mortar Element Refractory cement is a special type of cement, the main component of which is calcium aluminate, and usually contains a certain proportion of alumina. It is made […]

Lightweight insulation brick The classification of refractory insulation bricks can be divided according to different standards. The following are some of the main classification methods: Classification according to material composition: Alumina insulation bricks (bubble alumina bricks, lightweight alumina bricks) Alumina silicate insulation bricks (high alumina insulation bricks, clay insulation bricks) Silica insulation bricks Magnesia insulation […]

Although both Bubble Alumina Brick and Hollow Alumina Brick are used for heat insulation and insulation in high temperature environments, they have the following main differences in structure, performance and use: Bubble Alumina Brick Hollow Alumina Brick structure The bricks contain air bubbles, which are usually formed during the production process by introducing air or […]

silica bricks Silica bricks will expand at high temperatures, which is one of their inherent physical properties. Depending on the use conditions and environment, the expansion properties of silica bricks will affect their use in the furnace. 1. Expansion properties Expansion point: During the baking process, silica bricks will have four crystal transformation points at […]
