The production process of white corundum

The production process of white corundum

The production process of white corundum is the focus of our research, because it is directly related to the quality of white corundum, we must strictly control every detail in this process, including its feeding control. In the production process, the white corundum feeding put forward strict requirements, such as the requirements in the centralized feeding after the fixed time to stop feeding, mainly to ensure that the production furnace can be fully utilized, so as to expand the melting area, improve the utilization rate of raw materials. If it is not controlled, it is not good.

Detailed white corundum crystal block structure particle size analysis method.

Detailed white corundum crystal block structure particle size analysis method.

The production process of smelting of white corundum, due to the refining of alumina solution is not uniform, so the chemical composition and structure of the crystal block parts are uneven. This uneven situation is clearly visible in the broken white corundum crystal block. In the white corundum crystal block, due to the difference in appearance, structure and mineral composition, it can be divided into the following parts: the so-called upper rise, the bottom, the center, the edge and the bottom. The crystal block structure of white corundum is that the upper caving material is compact, porous, and the color is from light gray to dark gray, with various colors of pollution. Part of the surface is reddish brown, while the bottom is sponge-like and other grain structure, the color is rose, blue, and a few are purple brown.

The difference between white corundum and emery and the cause of color change

Emery packaging and specifications: 25 or 50kg woven bags, commonly used particle sizes can be divided into: 80-120 mesh emery, 40-60 mesh emery, 0.5-1mm emery, 1-2mm emery, 2-4mm emery, 4-8mm emery, etc. (Depending on customer needs). Using industrial alumina powder as raw material, it is made by cooling after melting at a high temperature above 2000 degrees in an arc. After crushing and shaping, magnetic separation to remove iron, and screening into various particle sizes, its quality white corundum is suitable for making ceramics, resin consolidated abrasives, grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc., and can also be used for making

Development of White Corundum in Metallurgical Industry Arc Wheel Dressing

Development of White Corundum in Metallurgical Industry Arc Wheel Dressing

White corundum is widely used as we all know. Product size according to international standards and the standard production, can be processed according to user requirements granularity. The general particle size number is F4 ~ F220, and its chemical composition varies depending on the particle size. The prominent point is that the crystal size is small and impact resistant. If the self-grinding machine is used to process and break, the particles are mostly spherical particles, the surface is dry and clean, and it is easy to bond. White corundum is the main raw material of alumina powder, suitable for chromium oxide, etc., by high temperature smelting. Chromium corundum is pink, the hardness is similar to that of white corundum, and the toughness is higher than that of white corundum. Abrasives made of white corundum have good durability and high grinding finish. apply
