NM400
一般来说,其它材质钢板进行淬火一般都是选择热温进行淬火,但是这样做的结果钢板的坚固性不是很好。但是HARDOX500耐磨板采用的是冷温淬火技术,冷温很难掌握,同时还要引进一系列的设备。
Generally speaking, other steel plates are usually quenched at hot temperature, but the result of this is not very good. However, hardox500 wear-resistant plate adopts cold temperature quenching technology, which is difficult to master. At the same time, a series of equipment should be introduced.
NM400耐磨板的淬火是将加热到临界温度以上,保温一段时间,然后很快放入淬火剂中,使其温度骤然降低,以大于临界冷却速度的速度急速冷却,而获得以马氏体为主的不平衡组织的热处理方法。最早的端面密封采用编制麻辫进行密封,寿命短,工人劳动强度大。
The quenching of nm400 wear-resistant plate is a heat treatment method that heating to the critical temperature, holding for a period of time, and then quickly putting into the quenching agent to make its temperature drop suddenly, and rapidly cooling at a speed greater than the critical cooling rate, so as to obtain the unbalanced structure dominated by martensite. The earliest end face seal is made of braid, which has short service life and high labor intensity.
要进一步发挥市场配置资源的基础性作用,通过价格机制、供求机制、竞争机制引导过剩行业优胜劣汰,通过行业整合兼并,实现资源优化配置。一般用化学和电解两种方法做酸洗处理,管道防腐只采用化学酸洗,可以去除氧化皮、铁锈、旧涂层,有时可用其作为喷砂除锈后的再处理。焊接小车运送工件沿轨道行走,双丝外焊机:用于对NM400耐磨板进行自动埋弧焊接,配合主机实现对工件的焊接。揉捏后要脱管定径。 利用溶剂、以达到去除油、油脂、灰尘、润滑剂和类似的有机物。
We should further play the basic role of the market in allocating resources, guide the surplus industries to survive and eliminate the fittest through price mechanism, supply and demand mechanism and competition mechanism, and realize the optimal allocation of resources through industry integration and merger. Generally, chemical and electrolytic pickling methods are used for pickling. Chemical pickling is only used for pipeline anticorrosion, which can remove oxide scale, rust and old coating. Sometimes, it can be used as the reprocessing after sand blasting. The welding trolley transports the workpiece along the track, and the double wire external welding machine is used for automatic submerged arc welding of nm400 wear-resistant plate, and realizes the welding of workpiece with the host machine. After kneading, take off the pipe and fix the diameter. Use solvent to remove oil, grease, dust, lubricant and similar organic matter.
