To mete the higher and higher demand for quality of steels and promote the continuous development of hot metal pre-treating technique, the new type of hot metal dephosphorization pre-treating technique is developed in Cheng Steel:for the particularity of vanadium-bearing hot metal in Cheng Steel, based on the traditional process, the new type of semisteel dephosphorization pre -treating technique is developed, the phosphorous content in semi-steel is reduced, the operation of les slag and high catch carbon in converter is realized, the consumption of lime, iron and steel materials and alloy is reduced, the quality of steels effec-tively improved.All of these have an important significance for development of more kinds of low phosphor-ous steel.
