关于机械产量，二十世纪七十年代后期，控制冷却技术的发展使得钢板轧制中的TMCP技术得到广泛发展。
With regard to mechanical production, the development of cooling technology in the late 1970s made the TMCP technology develop widely in steel plate rolling.
辊系快速整体更换不需吊车，采甩轧辊牵引小车和横移台车结合的换辊方式，导卫横梁安装在轧机轴承座上，更换轧辊时,导卫及横梁随辊系整套从牌坊窗口中拖出，一次换辊时间仅为20min.
You don"t need to replace the whole fast roller roller way for mining crane, trolley and swing roller tr***ersing trolley with the guide beam is installed on the bearing seat of rolling mill, roll changing, guide and beam with roll set pulled from the housing window, a roll change time is only 20min.
轧制H型钢时，轧机作为机架使用，带有两个水平辊和两个立辊，对轧件的腹板和翼缘四面碾压。轧制普通型钢时，轧机转换成两辊机架，即不带立辊，只带有两个水平辊，对轧件进行轧制.
When rolling H steel, the universal mill is used as a universal frame, with two horizontal rolls and two vertical rolls, which are rolled over the web and flange of the rolled piece. When rolling ordinary steel, the universal rolling mill is converted into a two roll frame, that is, without a vertical roll, with only two horizontal rolls, rolling the rolled piece.
连续加热炉连续加热炉包括推钢式加热炉、步进式炉、转底式炉、分室式炉等连续加热炉，但习惯上常指推钢式炉。连续加热炉多数用于轧制前加热金属料坯，少数用于锻造和热处理。
It is named according to the varieties of rolling, the type of rolling mill and the nominal size. The principle of "nominal size"
For rolling mills, they are named after the gear ring and the pitch diameter of the herringbone gear.
