Practice of Improving the Castability of Cold Heading Steel Produced From Small Billets
During the production of cold heading steel by a small billet continuous casting machine in a steel plant of a certain steel enterprise,there was a problem with the castability of the molten steel,which was manifested by the rise of the plug rod and the fluctuation of the crystallizer liquid level.In the continuous casting process,an analysis was conducted on the blockage of the water nozzle in aluminum containing cold heading steel,and based on the analysis results,it was found that the main sources of aggregates were Al2O3 and CaS.A solution has been proposed to effectively reduce quality fluctuations and production accidents caused by clogged water outlets.
