厚板产品一般在轧制后用热矫直机进行矫直。但是,近年来为了制造高强度、高韧性厚板,开发了在线热处理技术。钢板因通过冷却设备而温度下降,易造成板形不良。因此,用通常的矫直机进行矫直不能适应的现象增多。若通过增大矫直辊直径来解决厚钢板的矫直,又影响较薄钢板的矫直效果,因此,希望开发一种对两者都有效的矫直机。 Plate products are generally straightened with a hot straightener after rolling. However, in recent years, in order to manufacture high-strength, high-toughness thick plate, an on-line heat treatment technology has been developed. Plate due to cooling equipment through the temperature drop, easy to cause bad shape. Therefore, the normal straightening machine straightening can not adapt to the phenomenon increased. If the straightening of the thick steel plate is solved by increasing the diameter of the straightening roller and also the straightening effect of the thinner steel plate, it is desirable to develop a straightening machine which is effective for both.
