Problems solved by technology

[0004] The purpose of the present invention is to solve the traditional furnace valves in the prior art. During production, the production process is unreasonable, and oil stains and active agents are easy to remain, which seriously affects the normal use of the copper plug plate. The traditional furnace valves cannot The shortcomings of automatic closing, poor sealing, and poor anti-corrosion effect of traditional furnace valves are not conducive to the long-term use of furnace valves, and a production method for automatically closing furnace valves is proposed

[0045] A manufacturing method for automatically closing a furnace body valve, specifically comprising the following steps:

[0046] S1. Material preparation: Select a copper plate with moderate thickness, softness and hardness according to the requirements. The tensile strength of the copper plate is 420N / mm2, the elongation is 15%, and the hardness is 130HV;

[0047] S2. Stamping forming: put the copper plate into the stamping die for stamping and forming, and make it into a shape corresponding to the discharge pipe 11 of the furnace body 1, and obtain the copper plug plate 2, and the width of the copper plug plate 2 gradually increases from top to bottom big;

[0048] S3, welding hanging ring: weld the ring 4 on the top of the copper plug plate 2 made in S2, and weld the corresponding ring 4 on the inner wall of the discharge pipe 11;

[0049] S4. Polishing: use sandpaper and a file to polish the surface of the copper plug plate 2 to remove burrs;

[0050] S5, alkali washi...

Embodiment 2

[0056] The difference from Example 1 is that the outer wall of the high temperature resistant rubber layer 21 is sprayed with an anti-corrosion layer, and the anti-corrosion layer is prepared by the following method:

[0057]Take the following raw materials and weigh them by weight: 6 parts of water-based polyurethane resin, 4 parts of maleic acid resin, 2 parts of polyvinyl alcohol, 12 parts of epoxy furan resin, 5 parts of quartz powder, 6 parts of cellulose acetate, and 8 parts of thickener parts, 14 parts of binder, 6 parts of defoamer, 30 parts of deionized water;

[0058] A, material preparation: first weigh the above-mentioned raw materials;

[0059] B. Fusion of alcohol and fat: first pour deionized water into the blender, then pour water-based polyurethane resin, maleic acid resin, polyvinyl alcohol, epoxy furan resin into the blender, stir and mix, and control the stirring The rotation speed of the device is 40r / min, the temperature is 60 degrees Celsius, and the st...

Embodiment 3

[0066] The difference from Example 2 is the preparation of the anti-corrosion layer, and its specific preparation method is as follows:

[0067] Take the following raw materials and weigh them by weight: 8 parts of water-based polyurethane resin, 6 parts of maleic acid resin, 4 parts of polyvinyl alcohol, 14 parts of epoxy furan resin, 9 parts of quartz powder, 8 parts of cellulose acetate, and 12 parts of thickener parts, 18 parts of binder, 8 parts of defoamer, 50 parts of deionized water;

[0068] A, material preparation: first weigh the above-mentioned raw materials;

[0069] B. Fusion of alcohol and fat: first pour deionized water into the blender, then pour water-based polyurethane resin, maleic acid resin, polyvinyl alcohol, epoxy furan resin into the blender, stir and mix, and control the stirring The rotation speed of the device is 60r / min, the temperature is 70 degrees Celsius, and the stirring is controlled for 40 minutes;

[0070] C. Powder mixing: Put quartz pow...

Abstract

The invention discloses a manufacturing method of an automatic-closing furnace body valve. The manufacturing method of the automatic-closing furnace body valve comprises the steps of preparing materials, punch-forming, welding a hanging ring, polishing, alkali-washing for unoiling, acid pickling, drying, detecting and installing. According to the manufacturing method of the automatic-closing furnace body valve provided by the invention, through a series of operation such as preparing the materials, punch-forming, welding the hanging ring, polishing, alkali-washing for unoiling, acid pickling,drying, detecting and installing, a copper plug plate with a good sealing performance can be manufactured, oil stains and an active agent on the surface of the piston plate are eliminated, the smoothness of the copper plug plate is favorably improve, and the copper plug plate can be favorably long-acting used; through the function of an anti-corrosion layer, the copper plug plate is effectively prevented from being corroded, so that the corrosion resistance of the copper plug plate is improved, and the service life of the copper plug plate is greatly prolonged; a high-temperature-resistant rubber layer is coated on the outer wall of the copper plug plate, so that a sealing performance on a discharge pipe is improved through the elastic function of the high-temperature-resistant rubber layer, and the copper plug plate is smoothly plugged into the bottom part of the discharge pipe; and under the elastic function of a spring, the copper plug plate can automatically seal the bottom part ofthe discharge pipe.

Description

technical field [0001] The invention relates to the technical field of furnace body valves, in particular to a manufacturing method for automatically closing a furnace body valve. Background technique [0002] The furnace body is composed of upper and lower furnace body, furnace door, furnace door lifting mechanism, EBT tapping mechanism and so on. The lower furnace body adopts a cylindrical structure welded by steel plates, and the upper furnace body (referring to the part above 400mm on the slag line) generally adopts a water-cooled furnace with a tube-to-tube structure welded by seamless steel tubes under high power conditions. The wall has ball valves for the water in and out. The furnace shell is one of the important equipment of the vertical annealing furnace, and it is also the main barrier to isolate the atmosphere in the furnace from the outside atmosphere, so that the strip steel can realize the heat treatment function in a relatively independent environment. The...
