wear resistant 99% Alumina Ceramic eyelet yarn guide
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Alumina ceramic characteristics: First, good wear resistance Super hardness wear-resistant alloy hardness HRC ≥ 56, with good wear resistance and thermal stability. Second, excellent impact resistance, metal bonding properties, thermal shock resistance Performance The super-hard alloy bimetallic composite wear-resistant pipe produced by our company. The joint surface of the two metals is completely metallurgical and the use is safe and reliable. The thermal expansion coefficient of the two is equivalent, and there is no shrinkage and cracking. The outer wall of the pipe is made of steel pipe. The inner lining is made of super-hardness wear-resistant alloy. The product has high wear resistance and corrosion resistance of high alloy products, high mechanical properties and high impact resistance. 3. Good heat resistance and corrosion resistance. The matrix of hard alloy material has strong heat and corrosion resistance, and can show good corrosion resistance and wear resistance under high temperature or corrosive environment. Under wet state, corrosive medium and particle flushing interaction, adopt The ultra-hard wear-resistant alloy used in the as-cast state is suitable, and in the dry working condition with the abrasive wear as the main failure mode, an ultra-hard wear-resistant alloy material which may be overheat-treated to obtain a martensite matrix is selected. .four, The quality of the wear-resistant tube is made by the international advanced lost foam casting process, with high yield, high product compactness, uniform thickness and stable quality. 5. Transportation, installation and use are convenient. , quick joints, direct welding, etc. and because of the high anti-impact performance of the composite pipe, when partial blockage occurs in the pipeline system maintenance, it can be tapped or hammered at will, or can be freely cut, unloaded, welded, installed, overhauled. Very convenient.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
