Introduction:Compared with other conventional round steels, the compactness, compression ratio, tensile strength and yield strength of the steel are improved.
1、 Quality and performance comparison:
1. Wear resistant steel bar products have self-developed special wear-resistant steel. The raw materials purchased according to the user's requirements are also produced by the state-owned large special steel plant. Compared with other conventional round steels, the compactness, compression ratio, tensile strength and yield strength of the steel are improved. The properties and qualified rate of steel are guaranteed. The purchase of ordinary grinding rod is not a strict process.2. The hardness index of wear-resistant bar (hr58-22) is higher than that of ordinary steel bar (hr58-22) after using.
3. The straightness of wear-resistant steel bar products is treated by mechanical straightening machine to ensure that the ratio of out of straightness is less than one thousandth. The non straightness of ordinary grinding rod is generally 10 to 30 thousandth.
4. The fracture rate of wear-resistant steel bar products is generally less than 1%. The fracture rate of common grinding rod is large (uncertain).
5. The high temperature quenching process and medium temperature tempering process of wear-resistant steel bar products change the microstructure of medium, which makes the gold phase transformation of grinding rod more compact and wear-resistant. The impact toughness is also improved. There is no change in the quality of ordinary grinding rod.
2、 Comparison of application effect and cost:
1. The wear-resistant steel bar products have high wear resistance. Compared with ordinary steel bars, the time of stopping and adding rods is reduced by 20%, and the output is increased by 20%. At the same time, it reduces the labor intensity of workers.2. The good straightness of the wear-resistant steel bar ensures the accuracy and fineness of the abraded materials.
3. The good impact toughness of the wear-resistant steel bar ensures that the rod is not broken easily, and the accident and shutdown time are reduced.
4. The two ends of wear-resistant steel bar products are specially treated to ensure that both ends are not easily grinded, and the fine end is easy to bend and fracture. Therefore, ordinary grinding rod can not overcome this defect.
5. According to the comprehensive situation of users, the cost of wear-resistant steel bar can be reduced by 35% - 40% compared with ordinary grinding bar.
