| Abstract: | The formation of central segregation in tire cord steel and its influence on blooms were analysed.The key technologies for central segregation control of continuously cast bloom such as control and optimization of the casting speed and molten steel temperature,M-EMS,soft reduction of the solidification end and secondary cooling scheme were investigated.By way of application of those technologies the average central segregation index of carbon in WLX72A and WLX82A is controlled within the limit of below 1.042 and 1.027 respectively and the qualified rate of total blooms produced from CC achieves 99.97 %. |
