預制 污水檢查井模具 電力檢查井模具市場規模

  污水檢查井模具 電力檢查井模具市場規模電力檢查井模具市場規模與效益是根據制作要求而言,主要應用的是4個厚面板,5個厚筋板,在選材上嚴格按照標準的原材質鋼板,在電力檢查井模具施工上,要注意是需要現場澆筑還是預制完成,所以根據不同生產點,模具制作內容不同。電力檢查井模具選材的重點是對模具質量的保證,所以在下料前,要根據模具的尺寸大小,對筋板、面板進行劃分以及下料。電力檢查井模具施工過程中,要注意內外模的整體拆分,在預制檢查井生產時,內外模中間要放置連接孔,孔的位置需要根據管道位置來調節。而現澆生產過程則要注意上下模板對接的緊密性。

The scale and benefit of the mold Market of the power inspection well are based on the manufacturing requirements. 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 quality. 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.

污水檢查井模具除了要求工作的檢查井矩陣有足夠高的強度和韌性的合理匹配,模具表面性質的工作性能和使用壽命是非常重要的。表面性能是指:耐磨,耐腐蝕、摩擦系數、疲勞性能等,以提高這些依賴的性能改善和提高基體材料非常有限,也不經濟,并通過表面處理技術,可以得到兩次結果與一半的努力,這是表面處理技術迅速發展的原因。檢查井鋼模具硬度主要取決于碳溶解在馬氏體體積(或氮),碳馬氏體含量取決于奧氏體化溫度和時間。

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.
