Head Toryanik E.I., Registration Date 26-10-2006 Organization Ukrainian State Researsh Institute for Carbochemistry popup.description2 The analysis was done for the actual technical state of batteries No.5-8 at OJSC "Markokhim". The technical measures were worked out for these batteries including the refractory pressurizing, temperature conditions for heating of blast furnaces with the refractory defects and the mode of coke quenching. Diagnostics was conducted for gas tightness of the refractory, walls of regenerators and blast-furnace gas valves. Blast-furnace gas valves were recommended to have the sealing from elastic materials. Industrial tests demonstrated efficiency of such sealings. The temperature coking conditions at the batteries of the second block was also investigated and recommendations were done for refractory safety with the simultaneous provision of the required heating up of coked charge, including the partly charged blast furnaces. In addition, for such blast furnaces it is necessary to use the rational mode of coke quenching for stabilizing coke humidity, which was investigated and introduced at the plant.
