Abstract
Measures have been developed OAO ZSMK for bottom blowing of metal in steel casting ladles of acid converter workshop No. 2, including provision of a stable argon pressure for blowing of bottom lances in furnace-ladle units (FLU), daily inspection of argon and nitrogen supply pipelines in metal finishing units (MFU) and FLU, replacement of easily-detachable joints in steel casting ladles and refractory tracts, shortening of the duration of melt processing in FLU to 40 min. Industrial tests of blowing assemblies of different construction are performed. Analysis of test results makes it possible to obtain the most stable and efficient operating indices in processing metal with argon in a FLU and to select a producer for refractory production taking account of the reliability and precision during its installation.
