At a recent national product appraisal meeting jointly organized by the China Machinery Industry Federation, State Grid Corporation, Liaoning Provincial Economic and Trade Commission, and Liaoning Provincial Power Grid Corporation, six new products developed by TBEA successfully passed the national level identification in one go. Among these, the OSS10-180000/220 three-phase autotransformer power transformer, developed by Shanghai Electric Power Company, was certified to reach international leading standards. Additionally, the ODFPSZ-533000/500 single-phase auto-coupled on-load voltage regulating transformer, exported to the United States, has been widely recognized for its advanced performance.
The SFP-720000/500 three-phase power transformer and the SFP10-370000/220 three-phase power transformer, both used at the Fujian Kemen Power Plant, have also achieved international advanced levels. The SFPSZ10-240000/220GY three-phase on-load voltage regulating transformer has similarly reached comparable standards. Moreover, another product with a capacity of 250,000 kVA has been acknowledged as a leader in domestic technology.
This achievement highlights TBEA's growing influence and technological innovation in the power equipment sector, reinforcing its position as a key player in both national and global markets. These developments are expected to further strengthen China's capabilities in high-voltage power transmission and distribution systems. (Source: China Industry News)
Sinking roller is an important roller type equipment, mainly used to achieve coating or anti-corrosion treatment on the surface of steel plates, aluminum plates and other materials by immersing the roller body into the rolling liquid pool. Sinking rollers are widely used in modern industrial fields, such as automobiles, shipbuilding, and other industries.
Structure and working principle
The sinking roller is mainly composed of a roller body, bearings, bearing brackets, and seals. The material of the roller body is generally cast steel, ductile iron or welded steel pipe. Its working principle is that when the steel or aluminum plate passes through the roller body, the sinking roller sinks it into the rolling liquid, then rises, causing the coating to adhere to the surface of the plate, and finally lifts the plate from the rolling liquid pool. Through this method, it is possible to achieve galvanizing and coating on the surface of the steel plate, giving it better performance.
Application scenarios
Sinking rollers have a wide range of applications in industrial production, such as:
Automotive industry: Used for surface treatment of sheet metal used in manufacturing car bodies to improve corrosion resistance and durability.
Shipbuilding field: used for anti-corrosion coating treatment of ship hull panels.
Other industries: surface coating and anti-corrosion treatment of tin plate, copper plate, stainless steel plate, galvanized plate, color coated plate, aluminum plate and other sheet materials.
Maintenance and upkeep
When the sinking roller is used in the molten galvanizing production line, it will be corroded and penetrated by the molten zinc liquid, resulting in pitting and pitting on the roller surface and becoming rough. In addition, high-speed movement can also accelerate wear and tear. Therefore, frequent replacement or maintenance of sinking rollers not only reduces the operating rate, but also increases production costs. In order to extend its service life, surface modification measures can be taken, such as improving the alloy composition of the roller substrate, adopting new sealing structures, etc
