为了使板坯在轧机咬入之前温度均匀、表面氧化轻微,综合分析了目前常用加热炉的优点和存在的不足,设计了一种新型的钛及钛合金板材轧前加热装置。该装置的主体包括一个箱式辊底电炉和一个替换工作辊道组,它们可根据需要随时上线或离线移动。与其它加热炉相比,该装置距离轧机更近,板坯出炉后的运输时间更短,最终入轧机前的板坯仍保持高的加热质量。该装置除了可进行钛及钛合金板坯的轧前加热、快速补温外,还可兼顾部分成品退火处理。其生产模式灵活,大大提高了设备的利用率和生产效率。
In order to make the slab uniform in temperature before the rolling mill bite, the surface oxidation is slight. Based on the analysis of the advantages and disadvantages of the common heating furnace, a new type of heating device for the rolling of titanium and titanium alloy sheet is designed. The main body of the device includes a box-type roller bottom electric furnace and a set of replacement work rolls, which can be moved on-line or off-line at any time as needed. Compared to other furnaces, the unit is closer to the mill and delivers shorter transport times after the slab has been removed, leaving the slab in front of the mill to maintain a high heating quality. In addition to the device for titanium and titanium alloy slab pre-rolling heating, rapid warming, but also take into account part of the finished annealing. Its production mode is flexible, greatly improving the utilization of equipment and production efficiency.
