Introduction to blank making process of flange forging in Shanxi
What are the aspects of the blank making process of flange forging in Shanxi? Let's introduce it to you:
② Name, model or power of spare parts and inspection tools.
② Initial forging temperature and initial forging temperature control of Shanxi flange forging: when each furnace is continuously heated for more than the specified heating time, and the actual furnace temperature shown by the heating furnace instrument reaches the specified temperature range, the billet can be forged.
③ Final forging temperature and final forging temperature control of Shanxi flange forging: when the blank making time is controlled within the specified time range, the final forging temperature meets the specified requirements; When the blank making time exceeds the specified time range and the shape and size of the blank do not meet the requirements of the blank drawing, it is allowed to return the blank to the furnace for reheating and continue forging the blank.
④ After the blank making of Shanxi flange forging, the hot billet shall be stacked and cooled on the ground without strong convection wind and moisture or in the pit (box); It is forbidden to put hot billet with cooling time ≤ 0.5h directly into water for rapid cooling.
⑤ Check the shape and size of 1-3 blanks according to the blank drawing (the specific sampling contents shall be listed one by one).
⑥ The number of the first piece of billet shall be ≤ 10, and 3-5 pieces shall be randomly taken out for die forging and trial forging. Only after the trial forging inspection is qualified can batch billet production be carried out.
