Alumina Ceramics:

The alumina ceramic centrifugal casting composite pipe is a composite pipe manufactured by "self-grown high-temperature synthesis-high-speed centrifugal technology", which forms a uniform, dense and smooth surface ceramic layer and transition layer at high temperature and high speed. The working temperature is 850-900 degrees. The ceramics will not fall, the weight is lighter, and the composite ceramics are wear-resistant and hard to solve the problem. In the past, the thickness is anti-wear. Straight pipes, elbows, elbows, tees, etc. are very good in the wear and tear industry. The ceramic pipe is made of high temperature and strong adhesive to paste the alumina ceramic piece on the inner wall of the pipe. After heating and solidification, it forms a firm anti-friction layer. The manufacturing process is simple and the cost is high. The use temperature can not exceed 100 degrees, which is not suitable for pipes. The spot-welding type wear-resistant ceramic pipe is to adhere the intermediate-pored alumina ceramic piece to the inner wall of the pipe with high temperature resistant strong adhesive, and at the same time, the spot welding process is used to firmly weld the ceramic to the inner wall of the steel pipe through the small hole. Protect the solder joints and screw on the ceramic caps. Each tile is not only intertwined with each other, but each porcelain forms a trapezoidal angle, which makes the ceramic blocks tightly connected without gaps; when the last piece of a circle is tightly embedded , porcelain block A 360° mechanical self-locking force is formed (this technique was applied to Chinese bridge construction projects centuries ago). Rivet connection, metal needs to be penetrated by a magnetic drill or drill, and then rivets It is connected with the cross-pressure type perforated ceramic sheet and metal. The production process of this kind of product is relatively complicated, the production cycle is longer and the cost is higher.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
