Production status and development trends of wire rod for steel cord in Asia

To introduce the production status of wire rod for steel cord in Asia： Nippon Steel （Japan） developped DLP cooling control technology to ensure the high quality of steel cord; super clean steel making process developped by Kobe Steel（Japan） well controlled P, S, O elements＇ component and inclusion＇ s content and property in steel, which made Kobe Steel＇ s wire rod for cord become the best among the world ; POSCO （ Korean ） to produce high quality wire rod for cord through optimizing Stelmor cooling technology ; Baosteel （China） wire rod for cord experienced production period of converter casting, electric surface small billet and electric surface big billet, and achieved from 72,82,86,92 to recent 96 grade; WISCO（China） by using 200 mm× 200 mm continuous casting billet technology to enhance perfrmance of wire rod for steel cord and close to Japan＇s level; Ansteel（China） wire rods quality for steel cord will improve more with its new 0.6 million ton competitive wire production line. To point out that with the development of tire product performance and its enterprises＇ requirement, steel cord will develop toward to ultrahigh strength.
