In the production of large-scale steel castings, saving energy and saving material have important significance for manufacturers to improve quality and efficiency. Large-scale steel casting manufacturers are paying more and more attention to the application of advanced technology and process in foundry production. And what should manufacturers start from, how to customize the improvement measures in management, quality, efficiency and technology according to their actual conditions and product characteristics?

As the large steel casting manufacturer in the north of Henan, CHAENG (Great Wall Steel Casting) believes that the improvement of quality is the best way to save energy and material. In the casting process of steel castings, due to many production processes, many influencing factors, and difficult quality control, especially for large steel castings, every detail must be handled well.

The large-scale steel castings produced by CHAENG involve a wide range of industries including cement machinery spare parts, steel castings for metallurgy industry, building materials industry, and hydropower industry, etc. On how to achieve quality and efficiency improvement, CHAENG takes the “fist product” - slag pot as an example, to analyze the treatment details of the casting slag pot and the control of the production process.

First of all, each piece of slag pot must be numerically simulated by computer numerical simulation technology before casting. The process analysis and quality prediction of the product forming process are carried out by numerical simulation technology, and the process optimization of slag pot casting is completed. To achieve the purpose of improving the quality of castings and reducing production costs.

Secondly, for the problem that the slag pot trunnion made of alloy steel and the pot body made of carbon steel are difficult to weld, CHAENG has customized a complete process to strictly control the welding problem in the slag pot production process.

Finally, the advanced flaw detection equipment is used for non-destructive testing of each slag pot to ensure the internal quality.

In summary, in order to achieve the purpose of improving quality and efficiency, we must fully consider safety, environmental protection, rational selection of raw materials, production process control, simulation of structural processes and material selection, casting, solidification process simulation, so that the process design is more rationalized, the production process is more clear, and the accuracy and practical application of the process design are improved.
