Manufacturing method of special-shaped ring forge piece of booster kettle flange

Abstract

The invention discloses a method for manufacturing a special-shaped ring forge piece of a pressurizing kettle flange, which comprises the following operation steps of: forming a kettle cover, pre-rolling a blank, replacing a special-shaped integrated main roller, rolling and forming, forming a kettle body, pre-rolling until an inner hole of the blank is larger than the maximum diameter of an integrated core roller, replacing the special-shaped integrated core roller, and forming the special-shaped ring forge piece of the pressurizing kettle flange. And then rolling and forming. According to the manufacturing method for the special-shaped ring forge piece of the pressurizing kettle flange, the core roller and the main roller are designed, a near-net forming mode is adopted, a kettle body and a kettle cover are rolled through a horizontal ring rolling machine, special-shaped rolling forming is adopted according to the product structure, a forming die is reasonably designed, and a performance heat treatment system is optimized; according to the special-shaped rolling production mode, the utilization rate of raw materials is increased, the production cycle is shortened, the manufacturing cost is reduced, the metal flow direction state of the product is guaranteed to the maximum extent, the comprehensive mechanical property of the product is further improved, and the market competitiveness of enterprises is further improved.

Description

technical field [0001] The invention relates to the field of booster stills, in particular to a method for manufacturing a special-shaped ring forging of a booster still flange. Background technique [0002] The manufacturing method of flange special-shaped ring forgings in booster kettle is a method for preparing special-shaped ring forgings. Booster kettle is a kind of equipment for pressurizing concrete blocks by steam. It belongs to medium and large pressure vessels and is widely used in petroleum, In chemical industry, pipe pile and other industries, due to the vigorous development of the real estate industry, there is a great demand for energy-saving and environmental protection products such as pipe piles and aerated bricks. Therefore, the demand for booster kettles has increased sharply in recent years. , kettle cover, etc., because the pressurized kettle has a toothed quick-opening device with a spherical crown head, the kettle cover and the kettle body need to be q...

Problems solved by technology

[0003] There are certain disadvantages in the existing manufacturing method of the special-shaped ring forging of the flange of the pressurized kettle. First, because the height of the kettle cover and the kettle body is generally not more than 400mm, and the specifications of the kettle are increased, the tooling cost cannot One specification corresponds to one set of molds, which is not conducive to people's use. In addition, because the industry is low-price competition, if rolling with a rectangular cross-section, the production cost is high and there is no market competitiveness, which brings certain difficulties to people's use process. Adverse effects, for this reason, we propose a method for manufacturing special-shaped ring forgings of pressurized kettle flanges
