Abstract:

There is a Beckenbach lime kiln in Xingsteel. Its daily production capacity is 500t in which the metallurgical lime for steelmaking is about 450t and lime powder for sintering is approximate 50t. In order to verify the control index of CaO content in the metallurgical lime of the kiln, a calcination test is carried out for metallurgical lime. The test has found that the control of CaO content of metallurgical lime in the range from 88% to 89% is feasible whether it is considered from the aspect of energy saving or from the aspect of slagging.
