鍛件加工后的調(diào)質(zhì)處理是如何展開(kāi)的?

　　How does the hardening and tempering process start after forging?

　　很多機(jī)械上面都會(huì)用到鍛件，不管是車輛還是農(nóng)用機(jī)械等等，鍛件是通過(guò)鍛件廠的鍛造設(shè)備外力作用下所產(chǎn)生塑形變形，來(lái)獲得具有一定形狀、尺寸、機(jī)械性能的加工方法。鍛件對(duì)于技術(shù)的要求是非常高的，因?yàn)樗枰覀兣筛鞣N模樣和樣子的，那么在鍛件成形后需要進(jìn)行冷卻，粗加工超聲波探傷后調(diào)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(qiáng)度的要求是在同一時(shí)間更高，高強(qiáng)度的同時(shí)保證滿足要??求是困難的。超長(zhǎng)鍛件，超重，并且在熱處理時(shí)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(shí)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(guò)容易引起火災(zāi)，和力學(xué)性能是很難實(shí)現(xiàn)的。為了防止淬火淬裂期間沖進(jìn)火海，一次性合格產(chǎn)品的機(jī)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.
