(1)连铸坯热送热装技术 连铸坯热装温度500～600℃,吨钢可降低成本70元,到2000年,若全国1/3连铸坯实现热送热装,每年降低成本10亿元。 目前,重点应做好板坯铸机与热宽带连轧机组之间的热送热装和小方坯铸机与小型连轧机组间的热送热装。 (2)加热炉综合节能技术 在轧钢工序中,加热炉耗能占70％以上。
(1) continuous casting hot billet hot charging technology Billet hot charging temperature 500 ~ 600 ℃, a ton of steel can reduce the cost of 70 yuan, by 2000, if the national one-third continuous casting billet to achieve hot delivery hot and cold, lower each year Cost 1 billion yuan. At present, the focus should be good slab casting machine and hot broadband hot rolling unit between the hot assembly and small billet caster and small hot rolling unit between the hot delivery. (2) heating furnace integrated energy-saving technology In the rolling process, furnace energy consumption accounted for more than 70%.
