机架是轧钢机的主要部件，它在轧钢过程中承担金属变形给予的负荷。因此要求机架有足够的强度和刚度，以保证设备安全和产品质量。型钢轧机的机架形式较多，常见的机架形式有开口式机架、闭口式机架和半闭口式机架3种。
The frame is the main component of the rolling mill, which bears the load given by the metal deformation during the rolling process. Therefore, the frame is required to h***e sufficient strength and stiffness to ensure the safety of the equipment and the quality of the product. There are more frame forms of the steel mill. There are 3 kinds of common frame forms: open frame, closed frame and half closed frame.
实现金属轧制过程的设备。泛指完成轧材生产全过程的装备，包括有主要设备、辅助设备、起重运输设备和附属设备等。但一般所说的轧机往往仅指主要设备。
A device for a metal rolling process. Generally refers to the equipment that completes the whole process of rolling material production, including main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment. Generally speaking, rolling mills usually refer to only the main equipments.
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.
