使用固体燃料的轧钢加热炉上,把现有热效率再提高一步的潜力还是存在的。而在加热质量方面,如何解决加热不均、烧裂、夹杂、脱炭等问题,也是迫切需要研究。近年来,我厂在提高提高热效率和改善加热质量方面,做了一些工业性试验。现仅将用Al_2O_3陶瓷砖料作炉筋管滑道的试验作一介绍。 (一)使用Al_2O_3陶磁砖料作滑道的炉子 1.炉型结构:炉子为用煤加热的二段式端出料连续加热炉(人工操作),能力为12吨/时,加热的炉料尺寸为28×80×2400毫米偏坯,出炉温度1150℃左右。炉型结构见图1。 2.Al_2O_3陶瓷砖料在炉内的砌筑:我们把它砌筑在两
There is still potential for further improvements in existing thermal efficiencies on rolling furnaces using solid fuels. In terms of heating quality, how to solve the problems of uneven heating, burning cracking, inclusion and carbon removal is an urgent need to study. In recent years, I plant to improve the thermal efficiency and improve the quality of heating, made some industrial tests. Now only with Al_2O_3 ceramic brick for the furnace tube slide test for an introduction. (A) the use of Al_2O_3 ceramic tile material for the chute furnace 1. Furnace structure: the furnace is heated with coal two-phase end of the continuous discharge furnace (manual operation), the capacity of 12 tons / hour, heated charge size For the 28 × 80 × 2400mm blank, baked temperature of about 1150 ℃. Furnace structure shown in Figure 1. 2.Al_2O_3 ceramic brick masonry in the furnace: We masonry it in two
