| Abstract: | The influence of chemical composition, inclusion and Pouring temperature on the tendency of hot tear formation of A3 steel is analyzed based on high temperature mechanical property and hot tear ring testing for continuous casting of small square billets used as common material A3 steel. Experimental results show that the chemical composition of molten steel has the decisive effect, whereas inclusions and pouring temperature also has remarkable influence on hot tear formation. |
