Trolley assembly annealing furnace

Abstract

The invention aims to provide a trolley assembly annealing furnace capable of regulating a required heating space according to the length of equipment, which comprises a furnace body consisting of a combined heat preserving furnace wall and a heat preserving furnace base; the front part of the furnace body is provided with a furnace door moving up and down, while the rear part is provided with a rear wall; the wall on the inside of the furnace wall is provided with a heat source; a trolley is provided with a movable wall which is in sealing contact with the inside and the top of the furnace wall, and can divide a furnace chamber into a front section and a rear section; and the trolley assembly annealing furnace is characterized in that: the furnace wall is formed by combining and splicing a plurality of detachably connected heated board unit bodies; the heat source is a plurality of mutual independent electric heaters, and the heated board unit bodies are provided with connecting parts for connecting the electric heaters; and the trolley is formed by orderly connecting a plurality of independent trolley units.

Description

technical field [0001] The invention relates to an integral annealing equipment used in the manufacturing process of large, medium and heavy pressure vessels in the chemical and petrochemical equipment manufacturing industry. Specifically, it is an assembled and combined annealing furnace used in conjunction with a trolley. Background technique [0002] In the manufacturing process of pressure vessels and other equipment, it is a very important step to carry out the special requirements of overall stress relief annealing and other heat treatment processes after the equipment is welded, which plays an important role in eliminating welding stress and preventing welding deformation and cracking. important role. As far as the current information about the chemical equipment manufacturing industry and the furnace industry is concerned, the size of the most common trolley-type annealing furnace is 15 meters long x 6.4 meters wide x 6.8 meters high, and the form is built in the for...

Problems solved by technology

[0003] Because the furnace body of the existing annealing furnace adopts a solid construction type (brick fiber) or a fixed type (steel fiber) furnace body, the change in the size and length of the furnace body is not easy to realize, and cannot adapt to the annealing requirements of equipment with different sizes, especially large-scale equipment; and , the heat source of the existing annealing furnace (such as the heating electric row) is fixedly connected on the inner wall of the furnace body in a meshed horizontal and vertical arrangement, and the layout of the furnace body and the heat source is difficult to change, which causes the existing annealing furnace to be unable to adjust the length of the equipment. Change, local super wide diameter to adjust the required furnace shape and heating space, the energy saving is not good
