氧化烧损是热连轧机组加热炉工艺过程中影响成材率的重要因素,研究了钢坯加热过程中钢种、加热温度、加热时间、炉内气氛对氧化烧损量的影响,并提出相应的改进措施。结果表明:钢中的碳可有效抑制钢坯被氧化;氧化烧损量随着加热温度的升高和加热时间的延长而增加;炉内气氛的氧化性越强,氧化烧损量越大。通过优化加热时间和加热温度、减少冷热坯混装、合理控制炉内气氛以及加强加热炉设备密封性等措施,可有效降低加热炉的氧化烧损量。
Oxidative burning loss is an important factor that affects the finished product rate in the process of hot strip mill. The effects of steel type, heating temperature, heating time and furnace atmosphere on the oxidation loss during the heating process are studied. improvement measures. The results show that carbon in steel can effectively suppress the oxidation of billets. The oxidation loss increases with the increase of heating temperature and heating time. The stronger the oxidation of the atmosphere in the furnace, the greater the oxidation loss. By optimizing the heating time and heating temperature, reducing the mixing of cold and hot billets, reasonable control of the furnace atmosphere and strengthening of the furnace sealing equipment and other measures, can effectively reduce the furnace oxidation loss.
