Although the large stainless steel castings look very large, the structure is also very simple compared with some fine castings. However, in the production of large stainless steel castings, the standard is particularly delicate, and the standard of surface smoothness of large stainless steel castings is higher than that of large stainless steel castings.

Large stainless steel castings occupy a particularly important proportion in the casting machinery stage. In the production and manufacturing of large stainless steel castings, for many reasons, the appearance of large stainless steel castings may not be very delicate. In other words, the appearance of large stainless steel castings will be very rough. Therefore, how can we reasonably put an end to this situation? The following will give you a brief explanation.

Among all kinds of large-scale stainless steel castings, there are many kinds of large-scale stainless steel castings used in machinery, the style is the most complex and the usage is large, so the standard will be higher. In the pouring stage of large-scale stainless steel castings, mold cracking, sand sticking on the surface of large-scale stainless steel castings, sand washing and other defects are very common, which results in poor appearance quality, which not only increases the workload of cleaning and finishing, but also is quite different from imported products. What level of dimensional accuracy can be achieved depends on a large number of detection data, we can not judge.

In the production and manufacturing of large-scale stainless steel castings, it is important not only to pay attention to the details, but also to the appearance of the products. Therefore, how to deal with the problem of rough appearance of large stainless steel castings? In the annealing treatment of machine tool bed castings: large stainless steel castings undergo two manual heat treatment to remove internal stress. The internal structure of large stainless steel casting is stable and not easy to deform. The machine bed castings with super large specifications can be fabricated by splicing, and large stainless steel castings can be cast separately. During production and processing, the whole production process is realized to ensure the installation and application accuracy.

All of these methods can make the quality of large stainless steel castings more excellent, and the appearance of the exquisite level is better.
