污水检查井模具 电力检查井模具市场规模电力检查井模具市场规模与效益是根据制作要求而言,主要应用的是4个厚面板,5个厚筋板,在选材上严格按照标准的原材质钢板,在电力检查井模具施工上,要注意是需要现场浇筑还是预制完成,所以根据不同生产点,模具制作内容不同。电力检查井模具选材的重点是对模具质量的保证,所以在下料前,要根据模具的尺寸大小,对筋板、面板进行划分以及下料。电力检查井模具施工过程中,要注意内外模的整体拆分,在预制检查井生产时,内外模中间要放置连接孔,孔的位置需要根据管道位置来调节。而现浇生产过程则要注意上下模板对接的紧密性。

The scale and benefit of the mold Market of the power inspection well are based on the manufacturing re The main application is 4 thick panels and 5 thick ribbed plates. The material selection is strictly in accordance with the standard raw steel plate. In the mold construction of the power inspection well, attention should be paid to whether it needs to be cast on site or prefabricated. Therefore, the mold manufacturing content varies according to different production sites. The key point of mold material selection for electric inspection well is to ensure the mold Therefore, before blanking, the rib plate and panel shall be divided and blanking shall be carried out according to the size of the mold. During the construction of the mold for the electric inspection well, attention shall be paid to the overall disassembly of the internal and external mold. During the production of the prefabricated inspection well, the connecting hole shall be placed in the middle of the internal and external mold, and the position of the hole shall be adjusted according to the pipe position. In the process of cast-in-place production, attention should be paid to the tightness of the connection between the upper and lower formworks.

污水检查井模具除了要求工作的检查井矩阵有足够高的强度和韧性的合理匹配,模具表面性质的工作性能和使用寿命是非常重要的。表面性能是指:耐磨,耐腐蚀、摩擦系数、疲劳性能等,以提高这些依赖的性能改善和提高基体材料非常有限,也不经济,并通过表面处理技术,可以得到两次结果与一半的努力,这是表面处理技术迅速发展的原因。检查井钢模具硬度主要取决于碳溶解在马氏体体积(或氮),碳马氏体含量取决于奥氏体化温度和时间。

In addition to the reasonable matching of strength and toughness of the working manhole matrix, the working performance and service life of the surface properties of the mould are very important. Surface properties refer to: wear resistance, corrosion resistance, friction coefficient, fatigue performance, etc. to improve these dependent properties is very limited and uneconomical. Through surface treatment technology, two results and half efforts can be obtained, which is the reason for the rapid development of surface treatment technology. The hardness of inspection well steel mould mainly depends on the volume of carbon dissolved in martensite (or nitrogen), and the content of carbon martensite depends on the austenitizing temperature and time.
