综观国内和国外小型和棒材轧钢车间的工艺布置可以看出:无论年产60～80万t引进的小型棒材轧钢车间,还是年产40～60万t国产的小型棒材轧钢车间,基本上都是全连续式的。其组成均由以下设备组合而成。1加热炉一般均为步进式加热炉(步进底式、步进梁式、步进梁底混合式),尤以步进梁 Looking at the domestic and foreign small and bar rolling process layout can be seen: regardless of the annual output of 60 ~ 800000 t introduction of small bar rolling workshop, or with an annual output of 40 ~ 600,000 t made of small bar rolling shop, the basic On the whole are all continuous. Its composition is composed of the following equipment. 1 heating furnace are generally step furnace (step-by-step, walking beam, walking beam bottom hybrid), especially in the walking beam
