What is stainless steel coil flat?
Most of the stainless steel coils leave the factory in whole rolls, which are mainly for the convenience of transportation; generally, when they are in the hands of the supplier, for the convenience of use, the stainless steel coils will be used with professional stainless steel flattening equipment, and the whole rolls of stainless steel coils will be cut. Kaiping, this process is called Kaiping;
What are the precautions in the process of slitting stainless steel coils?
During the slitting process, some quality problems will be caused due to improper operation or some unexpected factors. Common ones include bumps, scratches, and creases on the board surface. Excluding the problem of raw materials, the parts that have direct contact with the stainless steel coil, such as the pinch roller and the measuring wheel of the slitting machine, may cause the above defects. The size of the strip is generally more stringent, and the deviation of the deviation or the inaccurate data of the knife arrangement during the processing will cause the product size deviation. Incorrect knife clearance or pressing amount when arranging knives will cause excessive shear burrs, which should be paid special attention to when making welded pipe materials. When winding, due to tension and other reasons, the winding will be uneven or the roll will be deformed, which will indirectly cause defects to the product. In general, stainless steel coils with a thickness of 0.4mm and below are more likely to have the above quality problems.
What is stainless steel coil slitting?
Slitting of stainless steel coils is to separate a certain width of stainless steel strips into one or several stainless steel coils according to the specifications required by production. The process of slitting is prone to problems such as scratches, uneven rolls, high edge burrs, insufficient width, collapsed rolls, edge waves and knife bends. The problems that occur in the flattening and slitting of stainless steel coils, if serious, will directly affect the subsequent pipe making process, resulting in large size errors, rough surfaces, and insufficient straightness of the stainless steel pipes produced. Therefore, whether it is Kaiping or slitting, if you want high-quality stainless steel materials, the two common raw material treatments of slitting and Kaiping are indispensable processes in stainless steel processing.
