Abstract
The invention discloses a hydrogen fluoride rotary furnace body butt welding method, which comprises the following specific steps of: a) installing the same flanges on a front cylinder and a rear cylinder; b) randomly drilling an installation hole around an installation holes in each flange on the front cylinder and the rear cylinder; c) respectively placing the front cylinder on supporting roller devices and the rear cylinder on a molding bed, and enabling the front cylinder and the shell cylinder to be in contact with each other; d) enabling the installation hole in the flange on the front cylinder to correspond to the installation hole in the flange on the rear cylinder, and penetrating a bolt through the installation holes to tightly connect the front cylinder with the rear cylinder; e) welding the internal contact parts of the front cylinder and the rear cylinder through electric welding; f) after completion, removing the bolt, grinding off the flanges and welding the external parts of the front cylinder and the rear cylinder; and g) after completion, electrically planing the welded parts to enable the welded parts to be flat. The hydrogen fluoride rotary furnace body butt welding method has the beneficial effects that not only can the parallelism of the installed front cylinder and the installed rear cylinder be high, but also the weld is even and the service life of the cylinders can be effectively improved.
Description
Technical field
The present invention relates to a kind of method of body of heater docking, specifically a kind of method of hydrogen fluoride rotary furnace body of heater docking belongs to hydrogen fluoride rotary furnace technical field.
Background technology
The hydrogen fluoride rotary furnace is the equipment of producing hydrogen fluoride necessity, because body of heater is long, general body of heater all is to be welded into an integral body by conveyor front barrel and rear cylinder body, body of heater can rotate and remain on a higher temperature value when producing, so when the front and back cylindrical shell docks, the depth of parallelism of cylindrical shell always before and after not only requiring, and weld seam is more even, when carrying out the front and back barrel soldering now, what adopt is that the artificial visually examine calibrates, the error ratio that this method exists is larger, and the rotary furnace of producing is lower service life.
Summary of the invention
For the problem that above-mentioned prior art exists, the invention provides a kind of method of hydrogen fluoride rotary furnace body of heater docking, can not only make the front and back cylindrical shell depth of parallelism of installation high, and also even weld, the service life that can effectively improve cylindrical shell.
To achieve these goals, the technical solution used in the present invention is: a kind of method of hydrogen fluoride rotary furnace body of heater docking, and the concrete steps of the method are:
A. at an end of conveyor front barrel and an end of rear cylinder body identical ring flange is installed respectively, is provided with uniformly at least 4 installing holes on the ring flange;
B. bore arbitrarily an installing hole around the installing hole on the conveyor front barrel ring flange, bore an installing hole in the corresponding position of rear cylinder body ring flange;
C. respectively conveyor front barrel is placed on the riding wheel apparatus, rear cylinder body is placed on the moulding bed, and cylindrical shell is in contact with one another before and after making;
D. the rotation by riding wheel apparatus makes the installing hole on the conveyor front barrel ring flange mutually corresponding with installing hole on the rear cylinder body ring flange, and passes installing hole with bolt conveyor front barrel and rear cylinder body are fastenedly connected;
E. with electric welding the inside of front and back cylindrical shell contact is welded;
F. after finishing respectively disassembling bolts and ring flange polish off, then the outside of front and back cylindrical shell is welded;
G. after finishing its weld is carried out electric planer, make weld smooth.
Compared with prior art, the present invention adopts at ring flange and links to each other, and on ring flange, bore arbitrarily a hole, relative position in the time of so just connecting by cylindrical shell before and after just guaranteeing, can not only make the front and back cylindrical shell depth of parallelism of installation high, and even weld, the service life that can effectively improve cylindrical shell.
Description of drawings
Fig. 1 is scheme of installation of the present invention;
Fig. 2 is the schematic diagram of ring flange of the present invention.
Among the figure: 1, riding wheel apparatus, 2, conveyor front barrel, 3, the conveyor front barrel ring flange, 4, the rear cylinder body ring flange, 5, rear cylinder body, 6, moulding bed.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of method of hydrogen fluoride rotary furnace body of heater docking, the concrete steps of the method are:
A. at an end of conveyor front barrel 2 and an end of rear cylinder body 5 identical ring flange is installed respectively, is provided with uniformly at least 4 installing holes on the ring flange;
B. bore arbitrarily an installing hole around the installing hole on conveyor front barrel ring flange 3, bore an installing hole in the corresponding position of rear cylinder body ring flange 4;
C. respectively conveyor front barrel 2 is placed on the riding wheel apparatus, rear cylinder body 5 is placed on the moulding bed 6, and cylindrical shell is in contact with one another before and after making;
D. the rotation by riding wheel apparatus 1 makes the installing hole on the conveyor front barrel ring flange 3 mutually corresponding with installing hole on the rear cylinder body ring flange 4, and passes installing hole with bolt conveyor front barrel 2 and rear cylinder body 5 are fastenedly connected;
E. with electric welding the inside of front and back cylindrical shell contact is welded;
F. respectively disassembling bolts and ring flange are polished off after finishing, then the outside of front and back cylindrical shell is welded;
G. after finishing its weld is carried out electric planer, make weld smooth.
