炉卷轧机的优点是:基建投资小,占地面积少,生产能力约10～80×10~4t/a,可生产要求轧制温度范围窄的难变形钢带,如硅钢、不锈钢、耐热钢和其他特殊钢。缺点是带钢的质量较差,金属烧损大,换辊频繁,经济指标低。炉卷轧机自1949年投入工业性生产以来,全世界先后建造40多套,迄今仍有20多 Rolling mill has the advantage of small investment in infrastructure, small footprint, production capacity of about 10 ~ 80 × 10 ~ 4t / a, can produce the required rolling temperature range of narrow strip deformation, such as silicon steel, stainless steel, heat Steel and other special steel. The disadvantage is the poor quality of steel, metal burning large, frequent roll change, low economic indicators. Since it was put into industrial production in 1949, the furnace has more than 40 sets built around the world and there are still over 20
