Slag pot (slag ladle) are necessary equipment for steelmaking production in metallurgical enterprises. Their production and casting process must go through dozens of procedures, from mold manufacturing, inspection, molding sand preparation, modeling and core making to mold assembly, from metal raw materials preparation, batching, smelting, liquid metal treatment, pouring, falling sand, cleaning, heat treatment, to inspection, each process will affect the quality of the slag pot.

As the well-known Chinese steel casting slag pot manufacturer, CHAENG has shined in the large steel casting market at home and abroad. The reason is that each process is carefully crafted by the workers of CHAENG, and has been integrated into the "artisan spirit" of concentration, rigor, and excellence.
 
The first part: Optimized pouring, special treatment for special parts
 
Casting process one: Before casting, use the CAE software to digitally simulate the casting process, perform process analysis and quality prediction on the product's forming process, and continuously optimize the slag pot casting process.

Casting process two: CHAENG uses high-quality materials such as ZG230-450 / GS-16Mn5 / BS3100B2, which can make the casting slag pot have good plasticity and high melting point.
 
Casting process three: inspect the raw and auxiliary materials, put them into the electric arc furnace for smelting according to the proportion, and sample the molten iron for spectroscopic analysis, and perform the pouring according to the principle of “low temperature and fast pouring” and record the pouring time and temperature.
 
Casting process four: In order to ensure the quality of the slag pots, CHAENG adds a certain amount of alloying elements to the smelting molten steel, thereby increasing its strength, reducing the deformation of the product during use, and preventing the overall cracking of the slag pot.
 
Casting process five: Aiming at the problem that the two materials of alloy steel (slag pot trunnion) and carbon steel (pot body) are difficult to weld, CHAENG has customized a complete process to strictly control the welding problems in the slag pot production process.

The second part-grinding testing, efficient flaw detection
 
Casting process six: professional polishing and finishing team, large shot peening equipment, can effectively improve the appearance quality of slag pots, and make its surface finish meet customer requirements. 
 
Casting process flow seven: Use advanced flaw detection equipment to carry out 360° non-destructive flaw detection on the inner wall of the slag pot, trunnion and tilting mechanism, and the key parts can reach the level 2 flaw detection standard of GB7233-2007, or according to the customer's specific flaw detection standard.
 
The third part: increase control 
 
Casting process eight: In order to provide customers with higher quality production, in terms of management, CHAENG requires employees to strictly implement process specifications and improve employees' ability to execute related processes.
 
CHAENG has formulated strict rules and regulations and process operation specifications from the procurement, storage, and inspection of raw materials to the molding and smelting process operations. At the same time, strengthen the pre-furnace inspection and control of the alloy solution to ensure the chemical composition, metallographic structure, mechanical properties and processability of the castings, reduce casting defects, and lay the foundation for obtaining high-quality slag pots.
