Bimetallic wear hammer production process which double metal wear hammer crusher industry is today the preferred crusher parts, it has a low cost, good wear resistance, generally the price per ton is only about 1.5 million, but its wear resistance is equivalent to three times the life of high manganese steel alloy hammer model, so the majority of crusher manufacturers hope to feature high manganese steel hammer, so that customers feel do not wear, and then sell high-chrome bimetallic hammer crusher hammer manufacturers are not producing, but my company is specialized in the production of such high wear-resistant hammer, but some customers say that the hammer does not wear, it is therefore associated with the production process, the following for you For details about the bi-metal wear hammer production process. Bimetallic hammer, from the name, it is the two hammer, hammer head is worn parts is a high-chromium material, this material has high hardness, low chromium steel hammer handle has a certain hardness, but at the same time more It is important abrasion resistance, two materials on how to make a certain hammer, there are two bonding process, one is cold compound, also known as mechanical complex, is the first produced by the hammer handle, then put the hammer together with the hammer handle complex, which is part of the hammer and hammer handle cold combination, no metallurgical combine, in actual use, especially large hammer to crack easily turn around. The second process is a two-liquid compound, first irrigated hammer steel into a mold, and then added to the hammer handle steel mold, which is the formation of two kinds of steel metallurgical combine, this will not be as cold composite hammer hammer Like the first turn damaged. High chrome hammer hard iron nickel almost simultaneously developed. As early as 1930, the US high-chromium alloy hammer hammer studied prices, due to the high chromium content, so when Yi cupola melting chromium and carbon combine on the one hand, difficult to control the carbon content; the other hand, Since chromium oxide with burning cupola easily oxidized, so that the yield is very low chromium, therefore, in the melting furnace is still very rare cases, high chrome hammer can not get large-scale applications. After the Second World War, along with the massive use of alloy electric hammer ex-factory price, high chrome hammer before they get a larger development and application. Added chrome elements, a mesh structure type carbides M3C type becomes isolated M7C3 type and hardness carbide alloy hammer, increased from M3C of 840 ~ 1100HV to M7C3 of 1300 ~ 1500HV, which not only improves wear resistance, and improved toughness, their effectiveness is higher than the nickel hard cast iron. Therefore, since the advent of high chrome hammer, it has been the task is an ideal wear-resistant materials, the application has been widely promoted. China in the early 1970s, 20 of the world of high chrome hammer and achieved good economic returns in the mining, building materials and other industrial applications. High chrome hammer often divided hypoeutectic and hypereutectic two categories, the current high chrome hammer industry generally used generally hypoeutectic. Hypoeutectic high chromium hammer eutectic carbides were isolated strip, off the distribution network, thus hypoeutectic high chromium hammer has a high abrasion resistance and relatively poor toughness, can be used to produce bear has the impact of conditions in certain parts. And hypoeutectic high chromium hammer compared hypereutectic high chromium hammer carbon content and high volume chromium carbide volume fraction increased significantly, to promote material wear resistance. Hypereutectic high chromium hammer appeared coarse primary carbides, resulting in high chrome hammer toughness sharp decline in casting and heat treatment process easy to crack, so that the hammer reject rate increases, currently hypereutectic hammer Applications little. But with too refined and improved toughness hammer eutectic carbides future we will continue to expand the scope of application.
