Baosteel special steel car steering machine with rack steel continuous casting test succeeded

The continuous casting test of the rack steel for the steering gear of Baosteel Special Steel Branch Co., Ltd. was successfully completed. After the user's trial and feedback, all technical data have reached the German ZF enterprise standard.

The rack steel for car steering gear is recognized as the world's first-class quenched and tempered steel, mainly used for gears and spools in steering gears, and is a key safety component in the car system. Since the product was produced by special steel branch in the past by die casting, the output is low and cannot meet the market demand. Now, after the successful production test of continuous casting process, not only the product quality is further stabilized and improved, but also breaks through the bottleneck of mold casting production, which greatly reduces the production cost. Only the finished product rate can be increased by more than 10%, and the economic benefits are considerable.
