| Abstract: | Based on short service life of secondary air tuyere for carbon rotary kiln in aluminum electrolysis and the TRIZ theory,nine kinds of technical schemes available to structures and installation modes are offered. By function analysis,three axis analysis,problem solving,project selection and comprehensive evaluation,a series of technical schemes is adopted properly to improve cohesive strength among refractory castables,as well as to reduce the chipping impact of air temperature difference. The paper has practical significance to effectively increase the service life and actual yield of carbon rotary kiln. |
