High chrome hammer hard iron nickel almost simultaneously developed. As early as 1930, the United States high chrome hammer studied, due to the high chromium content high manganese steel hammer price, so on the one hand and carbon chromium easily incorporated cupola melting when the carbon content is difficult to control; another Also, because in terms of chromium oxide with easily oxidized cupola burning, so chromium yield is very low, therefore, in the melting furnace is still very rare cases, high chrome hammer can not get large-scale applications. After the Second World War, with the large-scale use, high chrome hammer furnace before we get a larger development and applications. Added chrome elements, a mesh structure type carbides M3C type becomes isolated M7C3 type carbide hardness and improve the M3C of 840 ~ 1100HV to M7C3 of 1300 ~ 1500HV, so that not only improve the wear resistance , but also improve the 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 high wear resistance with high toughness and relatively poor manganese steel hammer Model It can be used to produce a certain impact conditions of bear 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. 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, so the majority of crusher manufacturers hope to feature high manganese steel hammer high manganese steel hammer, so that customers feel do not wear, and then sell high-chrome bimetallic hammer head crusher manufacturers are not producing hammer, 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 is You elaborate double metal wear hammer production process. Bimetallic hammer high manganese steel hammer classification, 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 is a certain hardness, but more importantly, wear resistance, two materials on how to make a certain hammer, there are two bonding process, one is cold compound, also known as mechanical complex, it is the first produced by the hammer handle , then put the hammer and hammer handle complex together, the hammer and hammer handle belongs cold combination, there is 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. Qinggang high manganese steel hammer, high manganese steel hammer classification, Li Xin Heavy preferred (certified merchants) are provided by Gongyi City Heavy Machinery Manufacturing Co., Ltd.
