The wear-resistant round steel bar is refer to the grinding medium bar which was used in rod mill and coal mill.
The bar mill steel rod used by some users which is rolled by steel mill. The technical requirement is not high and its wear resistance is not ideal. When consumes a lot in use. It occasionally breaks the bar, bends the bar, chaotic bar, abrasion deviation, flattening rod and two ends are thin.
• In order to solve the above problems, our company organizes relevant experts to specialize in this product and develop a kind of steel bar with high wear resistance to replace the existing domestic consumable steel bar. After years of research, a new type of automatic production equipment, process and products for quenching and heat treatment wear-resistant steel bars have been developed. The wear resistance effect is 2 - 3 times that of steel bar made by rolling. Every year, it can save millions of tons or even tens of millions of tons of steel for the country. The size and specifications of the new alloy wear-resistant steel bar produced by the company can be adjusted according to the needs of customers, which greatly improves flexibility and eliminates unnecessary waste. At the same time, it prolongs the service life, saves the cost and reduces the labor force of workers. Don't worry about stopping mill every day and adding steel rods, however its greatly increase the output of rod mill.
