Embodiment 1

[0022] Autoclave kettle body vibration aging method, such as figure 1 The kettle body 8 shown is composed of a cylinder body and a toothed circular flange welded at both ends of the cylinder body, and a plurality of supports are welded on the lower part of the cylinder body; the kettle body 8 in this embodiment has a diameter of 2000 mm, a length of 30938 mm, and a weight of 28 tons, a support is welded every 3500 mm in the lower part of the cylinder. use as figure 2 , image 3 and Figure 4 The shown autoclave body vibration aging device, this autoclave body vibration aging device includes an exciter 1, the lower end of the exciter 1 has two ear plates 1-1 protruding sideways, The two lugs 1-1 of the device 1 are provided with arcuate pliers 3, and the upper end of the pliers 3 is threaded with a screw 2; An upper backing plate 4 and a lower backing plate 5 are provided, the bottom surface of the upper backing plate 4 is a convex arc surface; the top surface of the lower...

Embodiment 2

[0028] The autoclave kettle body vibration aging method, the operation steps include: padding between the support and the ground within the distance of 6900-7100 mm from both ends of the kettle body 8 is 500 mm in length, 200 mm in width and 200 mm in height. It is a rubber pad 6 of 100 mm; adjust the exciter 1 to vibrate for 45 minutes at the vibration aging frequency to complete the vibration aging of the still body 8. Other features are the same as in Example 1.

Abstract

The invention discloses a vibration aging method of a kettle body of a still kettle. The kettle body consists of a cylinder body and round flanges welded at two ends of the cylinder body; and a method for using a vibration aging comprises the following steps of: horizontally putting the kettle body, mounting rubber pads between support seats of the kettle body and the ground, and putting upper padding plates at the inner cylinder walls of the round flanges; putting vibration exciters on the top face of the upper padding plates, and clamping clamp bodies at two side lug plates of the vibration exciters and the outer cylinder walls of the round flanges; putting lower padding plates between the outer cylinder walls and the clamping surfaces of the clamp bodies, rigidly fixing the vibration exciters at the inner cylinder walls of the round flanges by screwing the upper ends of the clamp bodies, and putting vibration measurers at the outer cylinder walls, of the tops of the round flanges, in radial arrangement with the vibration exciters; starting the vibration exciters, and carrying out vibration for 15-45 minutes under a vibration aging frequency. Compared with the prior art, according to the vibration aging method of the kettle body of the still kettle, the welding residual stress of the kettle body can be quickly and effectively eliminated, the application of a vibration aging technique on the kettle body is realized, the 98% of thermal aging cost of the kettle body is lowered, and 80% of the thermal aging equipment investment is lowered.

Description

technical field [0001] The invention relates to the technical field of stress relief treatment of metal components, in particular to a method for performing vibration aging treatment on a kettle body. Background technique [0002] The autoclave is a large steel horizontal pressure vessel equipment used for autoclaving curing of new lightweight wall materials, concrete pipe piles and other construction products. The autoclave includes a kettle body and a kettle cover connected at both ends of the kettle body. The kettle body is composed of a cylinder body and a toothed circular flange welded at both ends of the cylinder body. seat. The autoclave is subjected to alternating stress during use, and the superposition of these stresses and the welding residual stress of the kettle body will produce the following defects: the weld between the cylinder and the round flange, the weld between the cylinder and the support Cracks and elliptical deformation of the round flange. [000...
