Super expected use effect of wear parts of "sky star"
The use of good mechanical equipment, must have good accessories support, good accessories pay attention to all aspects of his face. Crusher is a common equipment in the mining, metallurgy and building materials industries, such as hammer crusher, jaw crusher, impact crusher, cone crusher.
The crusher is mainly composed of hammer, jaw plate, plate hammer, crushing wall rolling mortar wall main components and other components, materials in strong impact loads, they appear at the same time because of the material and the macroscopic fracture, the relative friction between them cutting action, the abrasion wear is very serious, the main failure form of wear failure.
At present, the domestic and foreign jaw plate, big hammer, big hammer, rolling wall, broken wall and so on are made of high manganese steel or super high manganese steel, the matrix structure is austenite, and has good working hardening property. The work is subjected to strong shock conditions, the surface hardness can be quickly hardened 600HB from 170 ~ 225HB to 400 ~, while the heart still maintain the original hardness, and has excellent toughness and wear resistance of high manganese steel and high manganese steel after hardening are well, but for the wear parts the use condition is extremely bad, wear is serious, wear parts especially large crusher.
Zhengzhou Dingsheng company in the second generation of "big gold teeth" on the basis of technology developed by the third generation of "stars" of the hard alloy composite inlay technology, high manganese steel and low cost or high manganese steel as matrix material in large wear parts, working parts of their composite inlay hard alloy block, the double wear mask metal composite wear-resistant parts have excellent wear resistance, non wear masks have excellent plasticity and toughness, applied to large jaw plate, rolling mortar wall, broken wall, vertical mill roller, grinding mill lining plate, back breaking plate hammer, installed by the user to use, reflecting the effect of good agreement.
According to the user that under the same conditions, the high manganese steel (Mn13) rolling mortar wall / broken wall broken gold ore 60 thousand tons, super high manganese steel (Mn18) rolling mortar wall broken wall can be broken up 80 thousand tons of gold ore, Zhengzhou Dingsheng company production of "stars" (Xiang Hejin) super rolling mortar wall the broken wall broken / 153 thousand tons, a set of top two sets. The rolling wall is produced according to the sample mapping, 3.4 tons per ton, and the tungsten titanium alloy rod inlaid in the wall / broken wall of the rolling mill is still visible. The application effect of "super star" super roll wall / crushing wall is welcomed.
In addition, the "stars" of mill roller in the northwest of large cement plant mill use effect is good, compared to the original use of low alloy steel grinding roller surfacing the user's life, "stars" of the mill roll service life has been doubled, can continue to use for two or three months. From the aspects of product safety and cost performance, the "Star Star" vertical mill roller sleeve, vertical grinding disc and other products have been praised by the users.
