It is suitable for surface polishing of pavement, runway, special building and abrasives, steel, wood and glass. Sandpaper production is also commonly used. White corundum is widely used because of its excellent properties: high hardness and corrosion resistance. Impact resistance, high purity, no more impurities. Among the artificial corundum, white corundum and brown corundum are the most popular.
We pride ourselves on providing a quick and efficient production turnaround for our clients, no matter the size of the order. In the pressure range of practical application, the grinding efficiency increases with the increase of grinding pressure, because after the increase of grinding pressure, the particles embedded in the surface of the grinding tool are deeper, the cutting ability is enhanced, and the metal is removed more.
Generally, there are two kinds of charge layout: At the beginning of power transmission, most of the current flows through the furnace core due to the formation of non decomposed graphite and silicon carbide. new charge method and furnace bottom baking method. It is the mechanical properties of inorganic non-metal materials Of policies. At present, these use areas have been recognized by users.
However, if the hardness of the grinding tool is high and the grinding pressure is too large, the abrasive particles will be crushed due to the excessive load, which will reduce the cutting ability, reduce the grinding effect, deepen the scratches on the workpiece surface, and affect the surface roughness. When the content of aluminum sulfide in the melt is 6.5%, there are slender particles in addition to equiaxed crystal.
The new charge method loads the new charge composed of silica sand and coke into the reaction zone. In the furnace bottom roasting method, the new material composed of and coke is first loaded into the furnace bed at the bottom of the furnace for roasting, the volatile components in the coke are removed and sintered into larger particles, and then put into the reaction area after the next furnace.
The melting point of corundum furnace liquid decreases with the increase of the content of aluminum sulfide. The shape of corundum crystal has a great relationship with the content of aluminum sulfide in the furnace liquid. When the content of aluminum sulfide in the melt is close to 4%, the corundum crystallized from the melt is mainly equiaxed crystal, and the particle shape is particularly good.
Folding strength refers to the ability of brown corundum to resist durable deformation and cracking under the action of external forces. Therefore, low-dextrin dosage and wet molding material are used to ensure high dry billet strength to adapt to dry billet handling and kiln loading billet strength Requirements. The amount of aluminum sulfide is determined by the amount of pyrite added.
It is an important policy for measuring the ability of parts to adjust (that is, to resist failure). The first to touch is the flexural strength, also known as the flexural strength. It is the ultimate breaking stress of when receiving a bending moment per unit area, that is, it is adjusted only by the acceptance of the bending external force.

There are different types of molding materials for the production of ceramic abrasive tools in China. Some factories have lower requirements for the strength of the wet billet. For example, the aluminum base plate is used for drying and the aluminum base plate is used for drying. Suction cup, the workshop floor is relatively flat, wet billet transportation conditions are good, etc.
