轧钢机的轧辊在运转的过程主要还是靠电机传动带动减速机、齿轮箱主轴进行分配支撑的此外轧机的主轴还要对坯料轧制过程中产生的冲击力以及轧辊自身的重量进行承重，所以轧辊的质量和材质也要进行合理的选择，350扁铁扁钢轧机，一般是依据轧制速度与轧制产品规格来进行。

       The rolling mill roll in the process of running mainly depends on the motor drive reducer, gear box spindle distribution support in addition to the rolling mill spindle also on the billet rolling process of the impact force and the weight of the roll itself, so the quality and material of the roll should be reasonable choice, 350 flat iron flat mill, Generally according to the rolling speed and rolling product specifications to carry out.

       热轧扁钢是一般用途的截面为矩形的势轧长条钢材。其规格以厚度*宽度的毫米数表示，扁钢可以是成品钢材，用于构件、抚梯、桥梁及栅栏等。扁钢也可以作焊执着钢和的坯料和叠轧薄板的板坯。（材质：Q215，Q235），适用于厚度为3~60mm，宽度为10~200mm，截面为矩形的一般用途热轧扁钢。

       Hot rolled flat steel is a rectangular potential rolled strip of steel for general use. The specification is expressed in millimeters of thickness * width, flat steel can be finished steel, used for components, ladders, Bridges and fences. Flat steel can also be used as billet of welded steel and slab of laminated sheet. (Material: Q215, Q235), suitable for general purpose hot rolled flat steel with thickness of 3~60mm, width of 10~200mm and section of rectangle.
