How to solve the problems of stainless steel decorative color plates in the application?

Stainless steel decorative color plate has the advantages of beautiful surface and saving steel, and it shines in the application of construction, shipbuilding, transportation and machinery manufacturing industries. However, in practical applications, there are still some problems.

First, the problem of corrosion resistance.

The corrosion resistance of stainless steel decorative color plate is not permanent, but relative and conditional. In today's China and abroad, there is no steel grade that does not corrode in any environment. Similarly, stainless steel decorative color plates cannot be applied in any environment, and there is a chance of corrosion.

Second, the problem of raised head.

Because the stainless steel decorative color plate roller has surface grooves, the metal will flow into the grooves, resulting in different metal flow speeds on the upper and lower surfaces. In order to ensure no warping, the stainless steel decorative color plate frame adopts 'upper press-fitting roller' (the upper roller is a stainless steel decorative color plate roller). However, the greater the rolling pressure, the more likely the torque will be concentrated on the drive shaft of the stainless steel decorative color plate roller, resulting in an increase in the speed drop of the upper surface metal relative to the lower surface, which will cause the problem of warping.

Three, the edge of the roll peels off.

Stress concentration during rolling can cause this problem. In addition, the stainless steel decorative color plate roll body has a stainless steel decorative color plate groove with a depth of 2.0-2.5mm, and the pure rolling time is prolonged, which will cause such problems.

Faced with the above problems, what precautions should we take?

1. During roller processing, four rows of decorative panels on both sides should increase the chamfering and smoothness.

2. The abnormal stainless steel decorative color plate roller and the accident stainless steel decorative color plate roller realize closed management, and execute according to the 'abnormal roller or accident roller management system'.

3. Formulate the precision management of the main equipment of the finishing rolling mill, strengthen the spot inspection and maintenance of the equipment, improve the equipment precision of the finishing rolling transmission system, and reduce the dynamic speed drop.

4. Heating of stainless steel decorative color plate: Appropriately increase the target temperature of stainless steel decorative color plate.
