Abstract

The invention relates to a machining method for a high-temperature-resisting and high-wear-resisting conveying chain. The conveying chain comprises a chain plate and a pin shaft. The pin shaft is madeof wear-resisting pin shaft steel, and the wear-resisting pin shaft steel comprises the following chemical components including, by mass percent, 1.0%-1.2% of Mn, 0.8%-1.1% of Cr, 0.38%-0.45% of C, smaller than 0.025% of P, 0.3%-0.5% of Mo, 0.2%-0.35% of Si, 0.2%-0.5% of V, smaller than or equal to 0.25% of Ni, smaller than or equal to 0.025% of S and the balance Fe. The conveying chain manufactured through the method has high high-temperature-resisting performance and high wear-resisting performance and is suitable for being used in the metallurgical industry.

Description

technical field [0001] The invention relates to the technical field of metallurgical heat treatment, in particular to a processing method for a high-temperature resistant and highly wear-resistant conveyor chain. Background technique [0002] The conveyor chains used in the metallurgical industry need to have high temperature resistance and wear resistance. Currently, the conveyor chains (including chain plates and pins) used in the metallurgical industry are just ordinary chains. The chain pins are mainly carburized. Carburizing technology The gas carburizing method is the most common method, mainly for steel materials with low carbon content such as low carbon steel and low carbon alloy steel. After carburizing, the carbon content on the metal surface can reach 0.8%~1.2%, which makes the metal surface have higher hardness and strength while still maintaining the core toughness. Carburization of metal surfaces is due to the never-ending, irregular Brownian motion of molecu...
