C’onlinuous casting of thin slabs is a key state project for 7th and 8th five-year plans.On the basis of foundamental works,CISRI conducted the tests of 102 heats in Lanzhou Steel Works in the period of January 1991 —June 1992.Three slab assortments of 50×900 mm,70×900 mm,70×500 mm were examined.In June of 1992,412 t steel of 46 heats were cast with the efficiency of 91.3%.This result meets the requirement of the state in this period.The mould,heat transfer,casting technology and factors influencing slab’s qualities are investigated as well.
