[0004] The purpose of the present invention is to provide a production process of wear-resistant high manganese steel hammer head, in order to overcome the above-mentioned existing high manganese steel hammer head wear resistance is not enough, the service life is very short, the impact force suffered by the hammer head during work It is not large, so that the work hardening effect of the high manganese steel hammer head is not significant, and its resistance to erosion and wear is poor. The high manganese steel can only produce a high hardness surface hardened layer under the condition of a large impact force, and the impact force is small. At the same time, during the production process of the high manganese steel hammer, the surface of the high manganese steel hammer is not sprayed with any paint to increase its wear resistance, and the technical problem of using only the wear resistance of the high manganese steel hammer itself

Embodiment Construction
[0036] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0037] see Figure 1-5 As shown, a production process of a wear-resistant high manganese steel hammer, the high manganese steel hammer is made of the following raw materials by weight percentage: C: 1.2-1.4%, Si: 0.6-0.8%, Mn: 18-20% , Ni: 0.04-0.06%, Mo: 0.2-0.4%, Cr: 4-6%, Re: 1.0-1.2%, V: 1.2-1.4%, P: ≤0.02%, S: ≤0.02%, balance is Fe;
[0038] The specific operation steps of this production process are as follows:
[0039] Step 1: add scrap steel and pig iron for preliminary smelting, conduct component analysis, and a...

The invention discloses a production process of a wearproof high manganese steel hammerhead. The production process includes the steps of smelting; moulding sand; pouring and sand removing; quenchingand tempering treatment; and finish paint spraying. After wearproof ceramic powder is added into molten steel, uniform stirring is carried out, wherein the hardness of the wearproof ceramic powder isonly second to that of diamond, the wearproof performance of the wearproof ceramic power is far higher than that of wearproof steel and stainless steel, the wearproof performance of the produced highmanganese steel hammerhead is greatly improved, the service life of the high manganese steel hammerhead is greatly prolonged, finish paint is attached to the working portion of the high manganese steel hammerhead, the working portion of the high manganese steel hammerhead can be protected in the using process of the high manganese steel hammerhead, the wearproof performance of the high manganese steel hammerhead is greatly improved, the high manganese steel hammerhead is washed and subjected to water removal through a paint spraying device in the process, the spraying defects caused when impurities are generated during following finish paint spraying are avoided, and it is guaranteed that the high manganese steel hammerhead is subjected to wearproof protection through uniform spraying of the finish paint.
Description
technical field [0001] The invention relates to the field of production technology of high manganese steel hammer heads, in particular to a production technology of wear-resistant high manganese steel hammer heads. Background technique [0002] High manganese steel refers to alloy steel with a manganese content of more than 10%; high manganese steel will have a small amount of undissolved carbides after solid solution treatment, and can still be used when its quantity is small and meets the inspection standard. It is a kind of wear-resistant steel specially provided for heavy industry, and its application fields include quarrying, mining, excavation, coal industry, foundry and steel industry, etc.; while the high manganese steel hammer is a hammer made of high manganese steel . [0003] The existing high-manganese steel hammer head has insufficient wear resistance, and its service life is very short. The impact force on the hammer head during work is not large, so that the ...
