Technology Study Of Prolong Alumina Grog Kiln Operation Cycle

The factory is making alumina sintering production methods, chamotte kiln is making the alumina sintering production equipment and its host determines the sintering economic benefit. Due to the high energy sintering, want to realize the scale, alumina sintering only by improving the chamotte kiln running life.This breakthrough in the following aspects:the chamotte kiln of refractory research, anti-wear kiln head protect iron development, soft and mechanical coupling development etc. Also includes:the development and application of new insulation composite brick lining, extend lining life, Research and application of suitable for al2o3 chamotte kiln used new kiln head protect iron, prolong the service life of kiln head, Based on the working principle of hydraulic coupling, designing and developing the mechanical soft start-up coupling, significantly improved the exhaust fan operation reliability, Roller diameter 1200mm by will be changed, and the reliability of the wheel 1600mm and stability are improved, In al2o3 chamotte kiln, three-channel pulverized coal burners instead of single channel burner, get the expected effect.Through the above technical measures, the kiln operation has been extended period, the average operating cycle from 200 days to 300 days, and achieved remarkable results.
