Wear-resistant elbow

Wear-resistant elbow
Wear-resistant elbow
The wear-resistant elbow (ceramic wear-resistant pipe) was developed by experts in the field of new materials of the national high-tech "863" plan, and it is a new type of composite pipe with international advanced level. It consists of ceramic, transition, and steel back layers from the inside to the outside. The ceramic layer is a dense corundum ceramic formed at a high temperature above 2200 ° C, and is tightly bonded to the steel pipe through the transition layer. This product has good comprehensive properties of wear resistance, corrosion resistance, high temperature resistance, high strength, high toughness and high resistance to mechanical impact. It is a new material for transmission pipelines with world advanced technology.

Ceramic composite tube is manufactured by self-propagating high-temperature synthesis-centrifugation method. It is to put the seamless composite tube in the tube mold of the centrifuge, and add a mixture of iron red and aluminum powder into the composite tube . This mixture is called aluminizing agent in chemistry. After the centrifuge tube mold rotates to a certain speed, the aluminizing agent is ignited by a spark, and the aluminizing agent immediately burns itself, the combustion wave spreads rapidly, and a severe chemical reaction occurs during the spreading time, while a large amount of heat is released. Such heat can reach 3860K and 3600K under adiabatic conditions. It makes the original materials in the composite pipe and the products after the reaction, that is, alumina with a melting point of 2045 ° C (commonly known as corundum) all become melt. Because the reaction is very fast, only a few seconds, the molten reactants are quickly separated by the specific gravity under the action of centrifugal force. The specific gravity of iron in the product (7.85g / cm3) is twice that of alumina (3.95g / cm3). The heavier iron is thrown to the inner wall of the steel pipe by centrifugal force, and the lighter alumina is distributed in the inner layer of iron. . Due to the rapid heat absorption and heat transfer of the composite tube, alumina and iron quickly reach the freezing point, and the layer is solidified. The finally formed ceramic composite pipe is a corundum ceramic layer, an iron-based transition layer, and an external steel pipe layer from the inside to the outside. The molten iron and alumina at high temperature come into contact with the composite pipe wall, so that the inner wall of the composite pipe is in a semi-fused state, so that the iron layer and the composite pipe form a metallurgical bond, and the iron layer and the corundum ceramic layer also form a strong bond. Shear strength (that is, the strength when the ceramics are laminated in the axial direction) ≥ 15 MPa; crushing strength of ceramic composite pipes (that is, the strength when the ceramics in the pipes are crushed from the outside) ≥ 350 MPa.
