The slag pot is an important equipment for steelmaking in the metallurgical industry, and is a container for holding high-temperature slag produced in the iron and steel smelting process. Because it is a high temperature slag, the requirements for the material of the slag pot are very high. Commonly used materials are ductile iron and cast steel.  The performance comparison between the two material are as follows:

1.Slag pot performance strength: the tensile strength of spheroidal graphite cast iron slag pot (QT400-18) is greater than or equal to 400mpa; the tensile strength of cast steel slag pot (ZG25) is greater than or equal to 450mpa;

2. Slag pot heat resistance: ductile iron slag pot has good plasticity and good heat fatigue resistance; cast steel slag pot has strong heat resistance, good plasticity, and less cracks after rapid heating and cooling;

3. Slag pot deformation: brittle material ductile iron is not liable to deformation; plastic material cast steel is relatively liable to deformation and has good tensile strength and impact resistance;

4. Adhesion of slag: Ductile iron slag pot is not liable to adhere to steel slag, and the adhered slag is easy to clean. Cast steel slag pot is easy to stick steel slag, the adhered steel slag is cleaned through oxygen cutting.

CHAENG (Great Wall Steel Casting) adopts cast steel material ZG230-450 (ZG25), ZG270-500 (ZG35), ZG310-570 (ZG45), ZG340-640 (ZG55) and so on to produce slag pots. CHAENG uses InteCast software to numerically simulate the casting process, predict the problems during casting and optimize the process design. 

Advantages of CHAENG cast steel slag pot:

1. Many users: CHAENG slag pot / slag ladle is the common choice of many large world-renowned steel enterprises such as: Mittal Group, Tata Group, Taiwan Zhong Hua Iron& Steel Company, and so on.

2. Durable: CHAENG slag pot engineers adopt suitable material, customize and optimize the casting technology according to actual operating conditions. So CHAENG slag pots have: excellent high temperature mechanical properties, good thermal cracking resistance, stable manufacturing process and so on.

3. Longer service life: Up to 6000 times of usage frequency.  First maintenance can be done 2~3 months later than the average.

4. Mature casting processes, rich experienced manufacturer: CHAENG, as a rich experienced manufacturer, has mature casting process and technical teams. CHAENG performs digital simulation of casting process by means of  InteCast CAE before pouring, to achieve the optimization of slag pot casting process.

5. Level 2 of flaw detection: Ultrasonic and magnetic particle flaw detection level can reach the second level of standards.

6. Smooth side wall: Smooth inner wall of slag pot, to avoid adhering slag during operation.

7. Good appearance: CHAENG is quite skillful at shot blasting and sand blasting to ensure the good appearance of slag pot / slag ladle and improve paint adhesion.
