Ball mill end cover

1, the use of high-quality raw materials and mature process quality assurance  

Qianjin cast steel has rich experience in ball mill accessories processing, in the production process encountered many common problems in the industry, we continue to use new technology, new technology to enhance its wear resistance, improve the compressive performance, professional secondary flaw detection instrument can accurately detect the inside of the end cover, to ensure quality;  

2, tightly fitted parts, no leakage problem  

The feeding end cover produced by the forward cast steel can be adjusted to a certain extent for specific equipment, so that there is no gap between the end cover and the feeding parts, which effectively prevents the leakage problem caused by the insufficient fitting degree of some ball mill end cover and parts;  

3, stable operation, long service life  

The hollow shaft matching the forward cast steel processing and the end cover is also made of high-strength steel casting. In the early stage of casting, professional engineers also optimized the process structure of the hollow shaft according to the operation characteristics of the ball mill, ensuring the stability of the part under long-term operation and extending the service life of the part.  

4, mature technology, short delivery time  

Qianjin cast steel has a group of technical experts hired from well-known domestic casting manufacturers, responsible for the company's technology, process, management and operation, etc., established a set of scientific and perfect technology, production and operation management system, effectively ensure the product quality and delivery time required by customers;  

5. Perfect casting equipment and guarantee internal and external quality  

There are two alkaline arc furnaces of 30 tons and four large natural gas heat treatment furnaces. Arc gouging is used in the finishing of steel castings to guarantee the appearance and quality of products.  

The process flow  

First, simulation, modeling  

Before casting, the advanced cast steel should adopt CAE software for digital simulation of casting process, process analysis and quality prediction of product molding process through numerical simulation technology, and finish the process optimization of end cover casting.  

Two, casting, heat treatment  

The qualified raw and auxiliary materials are put into the electric arc furnace for smelting in proportion. In order to purify the liquid steel, the Great Wall Cast Steel revamps the molten steel ladle and refines the molten steel by argon blowing.  Sample hot metal for spectral analysis, after qualified, adhere to the principle of "low temperature fast casting" for casting, and record the pouring time and pouring temperature.  

Three, flaw detection, finishing  

Then cut pouring riser, flying edge and so on.  Professional polishing and finishing team, large shot peening equipment, effectively improve the appearance quality of hollow shaft, make its surface finish to meet customer requirements, and the use of professional flaw detection equipment for non-destructive inspection of each hollow shaft, to ensure the internal quality of hollow shaft, strictly prevent any defective products leaving the factory.
