用国产高速棒材输送系统实现一火成材

TO ACCOMPLISH THE REFORMATION OF ROLLING IN ONE HEATING BY THE DOMESTIC HIGH-SPEED BAR-DISCHARGING DEVICE

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 high-speed bar-discharging device are introduced in more detail,in cluding the structure and work principle of the pinch roll,brake and two-way collector.During rolling in one heating,the bar brake and pushing period can't match with increased rolling speed,which can be resolved by using the new reformed system.Furthermore,the period of reformation is short,and investment is less.Mean while,It will decrease the plant area and investment for constructing new small-sized mill.
