鍛件的生產工藝流程
加熱設備主要單室爐、推桿爐和臺式退火爐, 所有加熱爐均采用天然氣做燃料,鋼錠的加熱溫度一般在 1150℃~ 1240℃,冷鋼錠的加熱時間 1~5 小時左右,熱鋼錠的加熱時間則是 冷鋼錠加熱時間的一半,加熱后的鋼錠進入鍛造工序。 鍛造:被加熱至 1150~1240℃左右鋼錠從加熱爐中取出,然后 由操作機放入空氣錘或電液錘, 根據鋼錠的大小和鍛造比要求進行相 應的墩粗,拔長等工藝,實時監測鍛件尺寸,并通過紅外測溫儀控制 鍛造溫度。 檢驗:對鍛件毛坯進行初步檢驗,主要是外觀和尺寸的檢驗。外 觀方面主要檢驗是否存在裂紋等缺陷, 尺寸方面必須保證毛坯余量在 圖紙要求范圍內,并做好記錄。 熱處理:將鍛件加熱到預定溫度,保溫一定時間,然后以預定的 速度冷卻,以改善鍛件內部組織和性能的一種綜合工藝。其目的是消 除內應力,防止在機械加工時變形,調整硬度使鍛件利于切削加工。 經過熱處理后的鋼錠,根據材質的要求對鋼錠進行空冷或水冷、淬火 處理。
The heating equipment is mainly single room furnace, push rod furnace and table annealing furnace. All the reheating furnaces use natural gas as fuel. The heating temperature of the ingot is usually 1150 to 1240, the heating time of the cold steel ingot is about 1~5 hours. The heating time of the hot steel ingot is half of the cold steel ingot heating time, and the steel ingot after the heating is forged. Process. Forging: the steel ingot was heated to about 1150~1240 degrees and removed from the www.bddianlu.com.cn www.jiazanmiaomu.com www.dongwutongdiao.cn www.tongshizii.cn www.renwutongdiao.cn www.tongfoxiangg.cnfurnace, then the air hammer or electrohydraulic hammer was put into the machine by the operating machine. In accordance with the size of the ingot and the forging ratio, the corresponding piers and pulling lengths were carried out. The size of the forgings was monitored in real time, and the forging temperature was controlled by the infrared thermometer. Inspection: preliminary inspection of forgings blank is mainly based on the inspection of appearance and size. In appearance, the main inspection is whether there are cracks and other defects. Dimension must ensure that the blank margin is within the requirements of the drawings, and make good records. Heat treatment: a comprehensive process to improve the internal structure and performance of the forgings by heating the forgings to a predetermined temperature, holding a certain time, and then cooling at a predetermined speed. The purpose is to eliminate internal stress, prevent deformation during mechanical processing, and adjust hardness so that forging is advantageous to machining. After heat treatment, the ingot is air-cooled or water cooled and quenched according to the requirements of the material.
