S690QL steel number will fluctuate within a narrow range

Cold rolled S690QL steel number steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner S690QL steel number steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

The shape defects of wear-resistant plates, S690QL steel number mainly refer to various waves and buckles existing in continuous rolling mill products. The main reasons are the unbalanced load distribution of the racks, poor tension settings between racks, and unreasonable work roll profiles. This kind of defect is easy to cause the adhesion phenomenon in the hood retreat, which has a great impact on the wear-resistant plates product quality. Edge defects are mainly caused by poor pickling trimming quality or poor plasticity of strip steel.
