为了推广履带推土机行走机构易损件质量攻关成果,提高红旗-100拖拉机支重轮的使用寿命和生产效率,我厂自行设计制造了一台中频自动淬火机床。原来箱式炉整体加热-滚动面喷水淬火-低温回火工艺改为滚动面中频感应加热喷水淬火-自行回火,滚动面的硬度由HRC50～53提高到59～61,淬硬层由2.5～3毫米增至4.5～5毫米,使用寿命可显著提高;生产效率由2件/人·时提高到6件/人·时;每个轮的平均耗电量由11.5度降到5.8;劳动条件也得到了改善。
In order to promote the quality of the tracked bulldozer walking gear wearing parts and improve the service life and production efficiency of the red flag-100 tractor roller, our factory has designed and manufactured an intermediate frequency automatic quenching machine. The original box furnace overall heating - rolling surface water quenching - low temperature tempering process instead of rolling surface medium frequency induction heating water quenching - self-tempering, rolling surface hardness increased from HRC50 ~ 53 to 59 ~ 61, hardened layer by From 2.5 to 3 mm to 4.5 to 5 mm, the service life can be significantly improved; the production efficiency is increased from 2/person/hour to 6/person/hour; the average power consumption per wheel is reduced from 11.5 to 5.8; Labor conditions have also been improved.
