1, for the use of such products, it is necessary to check in advance whether there are defects in the product, such as cracks, bubbles and scarring, etc., which are very easy to lead to the phenomenon of fracture in the later use of the product, the risk is very high, and for the use of steel plates, there can be no stratification, otherwise it will seriously affect the smooth use of the product.
2, in use, it will be found that there are some thin layers of iron oxide and rust on the surface of the steel, as long as it does not affect the defects of the product, the existence of part is not relevant, mainly within a reasonable range. In addition, for the use of steel must pay attention to see whether it meets the relevant quality standards, because no matter what kind of occasion it is used in, if the quality is not up to standard, it will threaten human health.
3, in normal use, it will be found that there are some small defects on the surface of many steel, in fact, some small defects are allowed to exist, and these defects can be cleaned by grinding, but we must ensure the thickness of the steel, to smooth the surrounding treatment, no edges and corners, so as to ensure the normal use of the product. In addition, if the steel needs to be welded, it is also necessary to pay attention to the operation in accordance with relevant regulations.
