陈登福, 温良英, 董凌燕, et al. A Study on Simulation of Stirring and Scouring Action in Top and Bottom Combined Blown Converter at Chongqing Steel[J]. Special Steel, 2005, 26(2): 6-8.DOI:
According to characteristics of the depth of metal and slag
the furnace structure and size
and the revamping design for an top-blown converter (charging metal 85 t) modified to a top and bottom combined blown converter
a cold simulation model for top and bottom combined converter has been designed and established to test and study the effect of flow impinging on converter bath
the mixing characteristics of bath in different melting period and the scouring action of melt on furnace wall
the test results showed that the reasonable bottom blown strength was 0.06~0.11 m
3
/min▪t for the converter at Chongqing Steel; and in top and bottom blown
the bath mixing time was lowest by operation at basic lance location.
