Scarring Cracks of slabs aren＊t fully cleaned up, thus it forms scars in the rolling; if the slab is overheating, especially chromium stainless steel, easily form scars. There is a large number of non-metallic inclusions on the surface of the billet…

After refining and blowing outside the furnace, the composition of the steel in any position in the ladle is uniform. And after solidification, chemical compositions of continuous casting billet from center to surface isn＊t same, even some of the differences are very large. This non-uniformity of the composition is called…

With advanced communication and internet technology, the intelligence level of steel mills has been greatly improved, and more automation functions such as online automatic tracking and monitoring, loading, cutting, sampling,stacking have been realized, that reduces workers’ labor intensity, significantly improves plant efficiency and products get good consistency. Automation coding machine…

There are two casting processes in production of steel ingot or steel billet, die casting and continuous casting process. There are their typical merits and shortcomings, though the continuous casting process acts an important role, but the die casting process can’t be replaced. The die casting process is one batch…
