Abstract：The causes of sticking phenomenon in 1 900 mm slab continuous casting were analyzed. The results show that the main reason of sticking is that the protective slag between the green shell and the copper plate can not play a good lubrication and heat transfer function. Slag by optimizing performance, change the mold copper plate coating material, waterproofing crystallizer, choosing the right at the bottom of the nozzle immersion depth and nozzle angle, choosing appropriate three-way argon flow, standardization of pouring molten steel superheat control, constant speed, standardize the worker operation measures, such as 1 900 mm slab continuous caster sticking number by 20 times down to 4 times a month.
