Industrial Trial Production of X70 Pipeline Steel under Ultra Fast Cooling Conditions
A successful ultra fast cooling (UFC) technology has been applied to the plate rolling production line in Shouqin Metal Materials Co.Ltd..Industrial trials are reported for the production of X70 pipeline steels (about 70000 t) under UFC conditions.Pipeline steels with reasonably good properties have been produced on an industrial scale.UFC improves the temperature uniformity,the mechanical properties and the plate profile of X70 pipeline steel.The impact values of X70 pipeline steel at UFC mode exceed the standard requirements of X80 pipeline steel.The productivity is enhanced because cutting quantity of head and tail of the plate is reduced.The enhancement of control accuracy of the red back temperatures is favorable for industrial production of X70 pipeline steel.The reduced production of the steel-making has been industrialized achieved,since a new composition was designed by reducing the vanadium content to less than 0.045wt.%.
