鍛件加工后的調質處理是如何展開的?

　　How does the hardening and tempering process start after forging?

　　很多機械上面都會用到鍛件，不管是車輛還是農用機械等等，鍛件是通過鍛件廠的鍛造設備外力作用下所產生塑形變形，來獲得具有一定形狀、尺寸、機械性能的加工方法。鍛件對于技術的要求是非常高的，因為他需要我們弄成各種模樣和樣子的，那么在鍛件成形后需要進行冷卻，粗加工超聲波探傷后調理治療資格。

　　It will use a lot of mechanical forging, whether the vehicle or agricultural machinery, forging plastic deformation is produced by forging factory forging equipment under the action of external force processing method to obtain a certain shape, size, mechanical properties. The requirements of the forging for the technology are very high, because he needs us to make all kinds of appearance and appearance, then, after the forming of the forging needs to be cooled, rough ultrasonic testing, after the conditioning treatment qualification.

　　螺旋槳軸材料34鋼，其淬透性，性能要求，高強度的要求是在同一時間更高，高強度的同時保證滿足要??求是困難的。超長鍛件，超重，并且在熱處理時容易彎曲變形，容易淬裂，并起火燃燒，鍛造增加工件淬火的難度熱處理淬火前的同一時間沖。

　　Propeller shaft material 34 steel, its hardenability, performance requirements, high strength requirements are at the same time higher, high strength at the same time ensure that meet the requirements. Super long forgings are super heavy and easy to bend and deform during heat treatment. They are easy to be quenched and cracked, and burned, forged, increased the difficulty of quenching, and the same time before quenching.

　　要使用豎井式爐熱處理控制熱處理變形。水容易引起工件淬裂，油冷卻的通過容易引起火災，和力學性能是很難實現的。為了防止淬火淬裂期間沖進火海，一次性合格產品的機械性能，確定油冷卻的。

　　Use shaft furnace heat treatment to control heat treatment deformation. Water is easy to cause the workpiece to crack, and the cooling of oil is easy to cause fire, and it is difficult to realize the mechanical property. In order to prevent quenching, quenching cracking during the burst into flames, the mechanical properties of one-time qualified products to determine oil cooling.
