Ball mill end cover

rocessing advantages

1. Rich processing experience, reliable product quality using high-quality raw materials and mature technology, now Qianjin cast steel has rich experience in end cover manufacturing, in the production process encountered many common problems in the industry, we continue to use new technology The new process enhances its wear resistance, improves the compressive performance, at the same time, the use of secondary flaw detection instrument to detect the inside of the end cover, to ensure the quality of the product

The feeding end cover produced by the forward cast steel can be adjusted for specific equipment to make the end cover fit more closely with the feeding parts without any gap, which effectively prevents the leaking problem caused by insufficient fitting degree between the end cover and parts of the ball mill

3 stable running, long service life Forward of cast steel processing equipments of hollow shaft, and using high strength steel casting and become, in the early stage of the casting, professional engineers and operation characteristics of ball mill for ball mill end cover process structure is optimized with hollow shaft, largely to ensure the stability of the components in the long run, prolong the service life of the components

The process flow

Before casting, the casting steel should adopt CAE software to simulate the casting process digitally. Through numerical simulation technology, process analysis and quality prediction are carried out on the forming process of the product to complete the process optimization of the end cover casting

2. For casting heat treatment, the qualified raw and auxiliary materials are put into the electric arc furnace for smelting in proportion. In order to purify liquid steel, the molten steel ladle is reformed by advancing cast steel, and the molten steel is refined by argon blowing. Sample hot metal for spectral analysis, after qualified, adhere to the principle of low temperature casting fast casting, and record the pouring time and pouring temperature

After inspection and finishing, cutting and pouring riser flaring finishing process is carried out Professional polishing and finishing team, large shot peening equipment, effectively improve the appearance quality of the end cover and hollow shaft, so that its surface finish to meet customer requirements, and the use of professional flaw detection equipment for non-destructive detection of each end cover, to ensure the internal quality of the end cover and hollow shaft, to prevent defective products leaving the factory
