As one of the important metallurgical vessels, the slag pot plays an important role in steel production. It is mainly used for carrying steel slag from converters, steel slag from refining furnaces and ladle castings for continuous casting. The material of the slag pot body is mainly cast steel and cast iron. Cast steel slag pot is usually cast from molten steel such as 16Mn, ZG20, and Q235A.

As the star product of Great Wall Cast Steel, slag pot have their own unique advantages. The main advantage is that the life expectancy is more than 6000 times, which is far higher than other manufacturers. The service life of similar slag pots of other domestic manufacturers is about 6000 times.

Because the cumulative stress of the cast steel slag pots during the casting process and the harsh conditions they face in the process of use, will have a great impact on the life of the slag pots. Great Wall Cast Steel continues to improve in practical production through continuous exploration. The conditions and investment conditions have led to a leaping increase in the life of slag pots and completely eliminated the catastrophic accident of wearing cans.

The main improvements are the technological transformation of the process, the preheating of the slag cans, and the use of slag pots of different conditions in different locations and different slags, all of which have been improved. At the same time, other steel slag pots have also been summarized. The use of experience, combined with part of the theory and the actual situation of the factory, gradually formed a complete set of slag cans use process regulations, so that the life of slag pots has been significantly improved, reducing production costs. Among them, the slag pots with slag film technology and the practice of slow-warming and preheating have proved to be the most cost-effective and technically simple process measures for improving the service life of slag pots.
