连续加热炉在现代轧钢厂进行方钢坯、钢锭及厚板坯的加热方面占着首要地位,关系着轧制的产量和质量,尤其是在旧厂里,由于轧制系统设备和操作的改进,加热炉的生产能力始终落在后面,形成生产中最薄弱的环节。因此对改变炉子的加热制度和炉子结构来提高单位面积产量,是值得而且必须深入研究的。在研究这个问题之前,首先应该了解到钢料在炉内加热时间的长短关系着炉子产量的大小,而加热时间的长短一方面与钢料内部热传导系数等物理性质有关;另一方面与钢料外部加热环境有关。对于前者目前还无法加以改变,因此本文只探讨如何选择连续加 Continuous furnaces dominate the heating of square billets, ingots and thick slabs in modern rolling mills, and have a bearing on the production and quality of the rolling, especially in the old plants. Due to the improvements in the equipment and the operation of the rolling system, Furnace production capacity has always lagged behind, forming the weakest link in production. Therefore, it is worthwhile and necessary to change the system of heating furnace and the structure of the furnace to improve the yield per unit area. Before studying this issue, we should first understand that the length of the heating time of the steel in the furnace is related to the output of the furnace, and the length of the heating time is related to the physical properties such as the thermal conductivity of the steel; on the other hand, External heating environment. For the former still can not be changed, so this article only discusses how to choose continuous plus
