较详细地介绍了国产化的高速棒材输送系统，包括夹送辊，制动器及落料槽的结构及工作原理。应用该系统可解决在小型轧机用连铸坯一火成材改造中，因终轧速度提高而出现的棒材制动不下来和冷床拨料周期来不及的技术难题。而且改造周期短，投资少，也为新建小型轧机缩短厂房。降低投资创造了条件。 The domestic high-speed bar conveying system is introduced in detail, including the structure and working principle of pinch rollers, brakes and blanking slots. Application of the system can solve the technical problems that the bar material can not be braked due to the increase of the finish rolling speed and the cooling bed material feeding time is too late in the reforming of a slab for a small rolling mill. And the transformation cycle is short, less investment, but also shorten the plant for the new small mill. Lower investment has created the conditions.
