Abstract
The invention discloses a manufacturing technology for a fractionation column upper head. The technology process comprises the steps of raw material warehouse entry, raw material recheck, preprocessing, scribing and marking, blanking, edge processing, beveling, splicing, weld joint trimming, heat punch forming, correction and oxide skin eliminating, thermal treatment and nondestructive inspection, wherein a sand-blasting machine is adopted in the head blank material rust removal; plasma cutting is adopted; during edge processing, allowance cutting is conducted according to a scribing line first, and then heat cutting is adopted in the bevel processing according to pattern rules; the heating temperature of the heat punch forming is no higher than 1150 DEG C, and the final pressure temperature of the heat punch forming is no lower than 950 DEG C. According to the manufacturing technology for the fractionation column upper head, the equipment cost is low, the production efficiency is high, the operation is simple and convenient, and the welding precision is high.
