In the production of stainless steel water tank process will often encounter many difficulties, the main difficulties are classified into the following eight points.
1. Limited pickling capacity: the acid pickling and purifying paste used is not universal. For plasma cutting and flame cutting, black oxide scale is produced, which is very difficult to remove.
2. The scratch is difficult to remove: it is also difficult to remove all kinds of scratches after the whole process of pickling and purification, and the scratch can not be removed. The main reason is that the carbon steel and splashing impurities adhered to the surface of stainless steel water tank during scratch and welding, which cause chemical corrosion or electrochemical corrosion in the engineering of corrosive medium Should.
3. The scratch caused by human factors is relatively serious: in the process of hoisting, transportation and layout, the scratch caused by careless collision, delay or hammering is relatively severe, which makes the surface treatment of stainless steel more difficult and easy to rust after disposal.
4. Equipment elements: the main equipment of stainless steel water tank will cause scratches and creases during the process of passing through profiles, plates and bending, which makes it easy to rust after disposal.
5. Welding defects: the welding seams between the welding lines are relatively severe, which can be made up by manual process and mechanical grinding. The grinding traces caused by this way make the appearance of stainless steel uneven and affect the beauty.
6. Uneven grinding and polishing Purity: manual grinding after polishing and acid pickling purification treatment, it is very difficult to achieve the function of equalization and disposal for the workpieces added with area, which can not be treated uniformly, resulting in time-consuming waste.
7. Different appearance: if the welding gap is pickled and purified, the surface will be uneven, which will affect the appearance.
8. Other factors, stainless steel materials in the process of acquisition and storage, due to the hoisting and transportation process of bumps and scratches are also relatively serious, which is one of the causes of corrosion.
