sandvik high-chromium alloy hammer

High-chromium alloy hammer in the use of coal crushing

Hammer crusher is coal preparation plant, coking plant commonly used equipment, includinghigh-chromium alloy Sandvik hammer is the most easy to wear parts, and most manufacturers are mainly high manganese steel manufacture. After high manganese steel by water toughening treatment, the hardness of 180 ~ 220HBW, its characteristics are at greater compressive force or large impact loads, work hardening the surface will occur, take advantage of this performance was good wear sex. When broken coal-like substance, due to the low coal hardness (Mohs hardness 2-4), so in this working conditions, work hardening properties of high manganese steel can not be effectively play, resulting in potential wear and can not be fully exploited, it would be like as a low hardness of the material is very easy to wear, resulting in hammer of life is not high, reducing the operating rate of the equipment, increasing the labor intensity.

High chromium cast iron is good and receive special attention in a wear-resistant material properties, is considered to be the most durable material, especially for the impact of small high stress abrasion. Chang Lei Industrial Co., Ltd. produces high-chromium alloy hammer, made of Gr20 / Gr26, we 加添 other alloy materials and advanced heat treatment process to obtain a stable matrix organization, to meet customer requirements for wear-resistant materials submitted.

Sandvik high-chromium alloy hammer

Chang Lei company Sandvik high-chromium alloy hammer in an actual coal crushing, performance status has been praised by many customers, the service life is three times more than the high manganese steel, the coal preparation plant, coking plant efficiency significantly reduced high-chromium alloy hammer Sandvik replacement frequency, crushing greatly improved. Chang Lei due to join the company's advanced production technology and a variety of alloying elements, effectively avoiding the high chromium cast iron brittle defects, good safety performance, has made a very significant economic benefits.
