该工艺是对现有钢锭从炼钢铸锭到初轧均热的重大改革。其基本工艺是:采用新钢锭注后打水,最佳顺序脱模,缩短钢锭传搁时间,将入炉钢锭的焓均温度提高到1300℃以上;改变传统的钢锭分散装炉为密集装炉,钢锭表面紧密相贴,立放钢锭上面再横放钢锭,将均热炉装钢量扩大1倍以上;编制微能均热轧制的数学模型,依靠计算机的辅助分析,研制最佳升温速度、均热温度和
The process is a major reform of the existing steel ingot from the ingot to the beginning of rolling. The basic process is: the new steel ingot after the injection of water, the best order of release, shorten the spread of ingot time, the enthalpy of the ingot into the furnace above the average temperature of 1300 ℃; change the traditional ingot dispersion furnace is densely packed furnace , The ingot surface closely affixed, placed on top of the ingot and then horizontally placed ingot, the soaking furnace steel load to expand more than 1 times; preparation of micro energy is hot-rolled mathematic model, relying on computer-assisted analysis, the development of optimal heating rate , Soaking temperature and
