一、前言随着均热炉生产规模的扩大和自动化程度的提高,人们越来越关心的是节能和钢锭的加热质量,加热质量的好坏直接影响到轧制工序的顺利进行。目前,钢锭加热存在的主要缺陷是同一炉中的不同钢锭和同一钢锭的不同部位的温差较大,经常产生过烧和过硬等问题。大量研究表明:产生加热不均匀的主要原因是炉内温度不均匀,炉气流动不合理。炉温不均匀也主要是由于气流分布不均造成的,有的部位气流多,则炉温高,反之则低。迄今为止,人们在改进炉气流动方
I. Introduction With the expansion of the production scale of soaking furnaces and the improvement of the degree of automation, people are getting more and more concerned with the energy saving and heating quality of steel ingots. The quality of heating directly affects the smooth progress of the rolling process. At present, the main disadvantage of ingot heating is that the temperature difference between different ingots in the same furnace and different parts of the same ingot is relatively large, and problems such as over-burning and over-hardening often occur. A large number of studies have shown that: the main reason for uneven heating is the uneven temperature in the furnace, furnace gas flow unreasonable. Uneven furnace temperature is also mainly caused by uneven air flow distribution, and some parts of the air flow, the high temperature, otherwise low. So far, people are improving the flow of furnace gas
