马钢线材车间直接热装工艺及设备

Introduction to hot charging technology and equipment adopted by the Wire Shop of Ma Steel

介绍了热送热装效果较好的马钢第二炼钢厂线材车间的热送热装工艺设备,分析了连铸和轧钢的生产特点,说明了热送热装工艺设备布置。实践证明,马钢第二炼钢厂线材车间采用的热送热装工艺是比较顺畅的,热送热装率达到90%以上,加热炉小时产量提高了33%以上。生产线设计年产量45万t,2009年年产量已经突破了60万t大关。

This paper introduces the hot charging technology and equipment adopted by the Wire Shop of Ma Steel. Owing to better considering of features of steelmaking and wire rolling processes, the hot charging flow is smoother. Practice showed that the rate of hot charging has reached over 90 %, and the output of reheating furnace per hour has increased by more than 33 %. In 2009, actual annual production of the production line reached 600 000 t, higher than that of designed figure. The hot charging technology and equipment adopted by the Wire Shop of Ma Steel are good in energy saving and can be used as reference for similar scale steel wire plants.
