阐述了34×126矿用高强度圆环链的制造工艺,对圆环链中频感应热处理工艺参数的选择进行了研究,提出了矿用圆环链中频感应热处理参数的计算方案.对加热温度研究表明:大规格矿用圆环链的中频感应加热温度应在钢临界温度Ac3以上150~200℃,此时,热处理后园环链的强度和韧性表现最佳.
The manufacturing process of 34 × 126 mine high strength circular chain was expounded and the selection of process parameters for medium frequency induction heat treatment of circular chain was studied.The calculation scheme of medium frequency induction heat treatment parameters of mine circular chain was put forward.The heating temperature The results show that the mid-frequency induction heating temperature of large-scale mine circular chain should be 150 ~ 200 ℃ above the critical temperature Ac3 of the steel. At this moment, the strength and toughness of the circular chain after heat treatment show the best performance.
