摘要：

The refractory performance of Peirce-Smith converters is considered to be mainly determined by effects of process control and refractory installation design. BI-IP Copper has shown that, over the last four years, considerable improvements in tuyere line life can be affected by maintaining a uniform temperature in the operating converter and by ensuring sufficient and specific placement of expansion allowance in the construction of the refractory brickwork. A combination of optimized crane availability, rapid matte transfer, converter operating practices, new refractory installation techniques and applications has minimized out-of stack time. In addition, larger diameter tuyere pipes and hard piping have increased blowing rates and lowered cycle times, which has resulted in a tuyere line performance in excess of 62,500 tomes of blister copper before maintenance is required, This paper discusses the refractory installation design changes that were made to increase tuyere line life.
