The silicon steel sheet is coated with insulating paint, and its purpose is to limit the eddy current loop, so that the eddy current can only flow in one piece, so that the impedance of the eddy current loop is large, which limits the value of the eddy current. If there is no insulation between the sheets, the eddy current will pass through the adjacent silicon steel sheets, so that the impedance of the eddy current loop is smaller than that of a single sheet, the eddy current will increase, and the loss caused by the eddy current will increase rapidly. Generally speaking, the eddy current loss is proportional to the thickness of the silicon steel sheet.

Stainless steel still maintains a certain growth rate in the entire ferrous metal field, and the future consumption is good. From the trend interpretation, there are several pieces in the stainless steel industry that are very worthy of everyone's attention in the future. One is the curtain wall industry. So far, the proportion of stainless steel in the curtain wall industry is about 12%, which is relatively low. It is expected that in the next three to five years, the proportion of stainless steel used in stainless steel curtain walls will have an upward trend.

Stainless steel processing equipment classification is divided into shear equipment and surface treatment equipment,shear equipment is divided into cutting equipment and slitting equipment.In addition, from the thickness of stainless steel to divide, and there are cold and hot rolling processing equipment.

Last year,TSINGSHAN QN1803 stainless steel passed the CISA group standard and sold more than 100,000 tons in year 2019. Under the influence of the epidemic this year,according to the data statistics from January to the the end of may,the sales volume of TSINGSHAN QN series material products have exceeded the total volume of last year. Among them,what is the QN1803 growing against the trend? Many people think that it will become the mainstream product of the future,and may even fully replace the 304? So,what are the advantages of the QN1803 compared with 304?

How long can the colored stainless steel plate last without fading? This is also a problem that customers are more concerned about. The color of the color stainless steel plate on the market is bright and beautiful. It is inevitable that people will feel that the color is not so bright after a long time, and the color will fade after daily cleaning. In fact, these are all wrong ideas. Today we will briefly introduce the problem of fading.

The common stainless steel surface treatment processes mainly include: embossing, wire drawing, mirror surface, frosting, sandblasting, anti-fingerprint, etching, etc. Each process has unique effects and uses.

With the improvement of people's living standards, the tableware at home has gradually changed from porcelain tableware to stainless steel. This change is inevitable. So, what are the advantages and benefits of stainless steel tableware compared to traditional porcelain tableware?

With the rapid development of my country's automobile industry, the demand for fuel is increasing, but my country's oil resources are not rich, and fuel vehicles will cause great pollution to the environment. These problems have attracted the attention of the country, and the development of new energy vehicles become an effective way to alleviate the above problems.
