Composition for controlling spangle size, a coated steel product, and a coating method

   
   

A method of coating of steel products such as plate and sheet using an aluminum-zinc coating alloy includes modifying the coating bath with a particulate compound constituent in effective amounts to control the spangle facet size of the coated product, improve tension bend rust stain performance, and improve coated product paintability. Constituents include borides such as titanium boride and aluminum borides, carbides such as titanium carbide, and aluminides such as titanium aluminide. The method produces a coated steel product that does not require temper rolling for painting.

Метод покрытия стальных продуктов such as плита и лист используя сплав алюмини-qinka покрывая вклюает дорабатывать покрывая ванну с частичным составным составом в эффективное количество для того чтобы контролировать размер фасетки блесточки coated продукта, улучшать представление пятна ржавчины загиба напряжения, и улучшать coated paintability продукта. Составы вклюают бориды such as titanium борид и алюминиевые бориды, карбиды such as titanium карбид, и aluminides such as titanium aluminide. Метод производит coated стальной продукт не требует завальцовки закала для картины.
