Abstract：The quality and pourability of slab can be improved by adding liquid mould powder.Liquid and solid mould fluxes were used for various steel casting experiments on a slab caster in a factory. The consumption of liquid and solid mould fluxes, temperature distribution of mould, friction force of slab drawing and slab quality were compared, and the application prospect of liquid mould fluxes was prospected. The experimental results show that the consumption of liquid powder is increased by about 60% compared with that of solid powder, the temperature distribution of mould is more uniform, the friction force of continuous casting billet is reduced by about 15%, and the quality of slab is improved. The results show that in the continuous casting process, liquid mold flux can make the heat transfer between mould and slab more uniform, the lubrication effect of liquid mold flux is better, and the quality of slab can be improved. At the same time, it is expected that harmful ions such as F-, Na+ will not be added to improve environmental protection.
