| Abstract: | In the process of trial production of the corrosion resistant steel used for heating radiator by FISR technology in Tonghua Iron & Steel Co.,corner transverse crack and sticking accidents are apt to occur.In order to improve the uniformity of the solidification shell newly formed in the mould the chemical compositions and properties of the mould flux are optimized under the prerequisite that the good lubricating ability be ensured and thereby soft cooling of the shell at the meniscus of the mould is realize... |
