| Abstract: | In order to raise casting speed in FSTC thin-slab caster of Tangsteel, some measures were taken, such as ensuring a reasonable composition and temperature of molten steel, developing new type of mould powder for high casting speed production of caster, optimizing the structure of submerged nozzle and mould, applying of EMBr, etc. By means of corresponding measures, the maximum casting speed of FSTC thin-slab caster of tangsteel increased from 4.5 m/min to 6.0 m/min, and the slab has good surface quality, no defects such as segregation, porosity and shrinkage in microstructure of slab, The hot rolled coils also have good microstructure and properties. |
