  1、Mn13高锰耐磨钢板高锰耐磨钢板的切割,等离子切割分为水下等离子和空气等离子切割两种。采用水下等离子切割时,等离子气体可产生几千度的高温,高锰钢板切口处迅速熔化,并因水的阻隔避免了氧化,水又对钢板及时进行冷却,阻止碳化物析出,使钢板切割面光滑平整,无热影响区,切割质量最佳,是切割高锰钢的首选。也可采用空气等离子切割。

1. Mn13 high manganese wear-resistant steel plate high manganese wear-resistant steel plate cutting, plasma cutting is divided into underwater plasma and air plasma cutting two kinds. When underwater plasma cutting is adopted, the plasma gas can produce several thousand degrees of high temperature, and the high manganese steel plate can melt rapidly at the incision, and the oxidation is avoided due to the barrier of water. The water cools the steel plate in time to prevent carbide precipitation, so that the cutting surface of the steel plate is smooth, without heat affected zone, and the cutting quality is the best choice for cutting high manganese steel. Air plasma cutting can also be used.
2、Mn13高锰耐磨钢板高锰耐磨钢板也可采用传统的火焰切割。采用火焰切割时,建议采用切割小车,根据钢板厚度不同,采用不同规格的枪头,燃气和氧气配比调整适当(是中性火焰),是全部调整好后再开始下料,防止因中途熄火引弧造成断面缺口,影响切割质量。
2. Mn13 high manganese wear-resistant steel plate high manganese wear-resistant steel plate can also use the traditional flame cutting. When flame cutting is adopted, it is recommended to adopt cutting trolley. According to the thickness of steel plate, different specifications of gun head should be adopted. The proportion of gas and oxygen should be adjusted properly (neutral flame). Cutting should be started after all adjustment, so as to prevent the gap of section caused by arc ignition in the middle of the fire and affect the cutting quality.
3、Mn13高锰耐磨钢板高锰耐磨钢板的焊接:高锰耐磨钢板的焊接可采选用手工电弧焊的方法。 焊条选用D256(堆256)或D266(堆266)焊条;焊接前应打磨焊缝,要彻底清理工件坡口及边缘,去除铁锈、油污,同时将焊条烘干;焊接时,应选择小直径焊条(一般为3mm-3.5mm),小电流、高电压、多焊层、多焊道、快速焊接;如采用直流焊接,焊条接正极;焊接每层后要锤击焊缝,以提高其抗热裂纹能力。也可使用流动水快速降温。
3. Welding of Mn13 high manganese wear resistant steel plate: manual arc welding can be used for welding of high manganese wear resistant steel plate. D256 (du256) or d266 (du266) welding rod shall be selected; before welding, the welding seam shall be polished, the groove and edge of the workpiece shall be thoroughly cleaned, the rust and oil shall be removed, and the welding rod shall be dried at the same time; during welding, small diameter welding rod (generally 3mm-3.5mm) shall be selected, with low current, high voltage, multiple welding layers, multiple welding passes and fast welding; if DC welding is adopted, the welding rod shall be connected to the positive electrode; After welding each layer, the weld should be hammered to improve its hot crack resistance. It can also use flowing water to cool down quickly.
