Product description
Parameters
At present, some companies are using round steel in steel mills as grinding rods, such as 45 # steel, 40Mn, 40Cr, 65Mn, etc. The materials of these materials are still good, but the steel mills only leave the raw materials, and the round steel has not passed through. Quenching and tempering, its hardness is very low (only HRC12-25), its toughness is relatively poor, it is easy to break without stress relief, it is not abrasion resistant (consumption is very large), and it is easy to wear away (thin ends are thin, etc.), these problems have seriously affected the Benefits of the mill.
Our company uses heat treatment process to produce more wear-resistant steel bars. We use heat treatment to change its internal microstructure or change its chemical composition to improve its performance. The heat-treated round steel can be used for all kinds of steel rods for rod mills, steel rods for coal mills, steel rods for coal mills, and steel rods for grinders, which are harder and stronger than ordinary hot-rolled round steel. To be high, wear resistance is better, the cost is very high, has been widely used in domestic and foreign markets.
The new alloy wear-resistant steel rod produced by our company is produced by the latest method, the hardness can reach HRC45-55, the size and specifications can be adjusted according to customer needs, the flexibility is greatly improved, and unnecessary waste is eliminated. At the same time, it prolongs the service life, improves the production efficiency of the mill, saves production costs, and reduces the labor of workers.
