The development of a country mainly is depending on its developing level of each industrial fields, at present China's industrial capabilities in many areas can be competitive with foreign industry powers. Regardless of heat treatment technology, or in the field of hot galvanizing, China has been got ahead of other countries. Especially for the steel industry, the role of hot dip galvanizing is very important, because galvanizing can form a protective layer on the steel against rust, corrosion, etc., to make sure service life of steels are greatly extended. Hot dip galvanizing technology also need some supporting spare parts, sink roll is one of the very important workpieces.
As known to all, there are two kinds of galvanizing technology, one is electric galvanizing and another one is hot galvanizing. The metal coating formed by hot dip galvanizing is more compact, because without inorganic compound, and with better covering abilities than electric galvanizing. When steel galvanized, the galvanized layer can protect steel from atmospheric corrosion and delay its corrosion. In addition, galvanized steel surface has a special protective film, the surface will form a new protective coating if atmospheric corrosion happened. The most important is chemical protection can happen many times when corrosion occurred, so its protection ability for steel is very strong. Nowadays, with the development of high-voltage transmission and communication industries, people's requirements for various iron and steel parts are becoming higher and higher. The demanding for hot-dip galvanizing requirements are also increasing, which makes the sink roll playing more and more important role in the galvanizing field.
In the field of hot dip galvanizing, sink roll is very important, it is forming a continuous production line together with other spare parts. But sink roll and these parts are wear parts. At present, stainless steel is the most widely used for producing sink roll in China, but it is not wear-resistant for long term using. For solving this problem, most of factories choose sink rolls with coating, in this way sink roll and zinc liquid completely separated, this method is to protect sink roll from corrosion. Protective coatings for sink rolls used in continuous hot-dip galvanizing, the sprayed WC/Co cermet coating was formed on sink roll surface. And hence, surface quality of the galvanized steel can be highly improved. As the sink roll get older, it's wearing can't be avoided, but WELONG still working hard for improving quality and lift time of the sink roll. Not because it has a very important role in the field of hot dip galvanizing, but also because WELONG want to offer more qualified and durable sink rolls to customers, and help customers saved costs and win more and more projects from end customer. Do you have a question of sink rolls or other kinds of rolls for hot dip galvanizing? Or do you need support for your projects? Don't worry, we are here for help.
