自1957年创造了双锭轧制技术后,使初轧机能力较单锭轧制提高15～40%。在批修整风运动推动下,又进一步发展了双锭轧制新技术。1.轧制能力进一步提高:在1958年双锭轧制基础上又提高了6.66～37.8%2.双轧率提高:由1960年的50%(四种锭型)达到90%左右(八种锭型均可双轧)。
Since 1957 the creation of double-spindle rolling technology, the capacity of the early rolling mill rolling increased by 15 to 40%. Under the impetus of rectification and rectification movement, a new technology of double-spindle rolling has been further developed. 1. Further improvement of rolling capacity: 6.66 ~ 37.8% increased by double-spindle rolling in 1958. 2. Double-rolling rate increase: about 90% from 50% in 1960 (four ingot types) (eight Ingot can be double rolled).
