What are the forming methods for corundum crucibles?

We know that alumina crucibles are called corundum crucibles ，which are characterized by heat resistance, cold heat collection, and chemical corrosion resistance, but are not corrosion-resistant. In fact, corundum crucibles is cylindrical, shaped like a bucket. Despite its many advantages, corundum crucibles aluminum in can cause Alzheimer's disease. corundum crucibles There are many ways to form it. Today, I will tell us corundum crucibles forming methods.

(1) Dry pressing method.

Due to the symmetry of the four strokes of the hydraulic press, the pressed parts are different under different conditions of filling different granular materials. When the particles exceed 60μm, they can move freely between 60-200 mesh, losing the effect of working pressure. The press can be a hydraulic press or a stamping press, and can be a semi-active or fully active molding method. Dry-pressed composite porcelain carbon-carbon composite furnace body professional skills are limited to the design of authentic, the inner cavity thickness exceeds one millimeter, and the length-diameter ratio does not exceed four to one. The method of rubber and plastic products is biaxial or double.

(2) The working pressure of the powder press is 2 million Pascals. Moreover, the pressure applied by the equipment press varies with the amount of powder filling, which is very easy to increase the difference after calcination, thus reflecting the quality of the goods. The accuracy of the discharge amount largely reflects the accuracy of the entire mechanical limit of the crucible. corundum crucibles What is the forming method? Therefore, the powder is evenly dispersed in the whole dry pressing process, and the foaming agent filling effect is relatively high. The use value can reach 15 to 50 sheets per second. The material is introduced into the crucible.

(3) When the slurry absorbed by the construction site walls reaches the specified thickness, the hollow grouting must also pour out the remaining slurry. In order to better improve the growth of the blank, over-concentrated and over-thin slurry should be used. Grouting is a way to form composite porcelain. Generally, tap water is used as the solution substance, and then corundum zircon corundum crucible releasing agent and binder are added, organic waste gas is fully ground, and then poured into the gypsum mold. Due to the use of gypsum molds, the profit is low, and it is easy to form jade crucibles with large specifications and appropriate shapes. The key to this process is the preparation of composite slurry. Due to the hygroscopicity of the crucible gypsum mold capillaries, the mud is dried and fixed in the structure.

The above two corundum crucibles forming methods are actually a kind of slip casting method. The cost of these methods is relatively low, but the core is the manufacturing problem of the raw materials themselves, which should be noted.

Tangshan High-tech Industrial Park Chemical Physical and Chemical Porcelain Factory was established in 1989. The company is located in Tangshan, a developed industrial area on the Bohai Sea, with convenient transportation by rail, road, and airport. It is a company specializing in the research, development, production, and sales of refractory, acid and alkali resistant, wear-resistant, and high-temperature resistant physical and chemical porcelain. It currently has eight kiln production lines. The company has strong technical verification capabilities and is a major supplier of physical and chemical ceramics and corundum high-alumina ceramics in China.
