Example Embodiment

[0059] Example one:

[0060] Such as Figure 1 to Figure 4 As shown, an annealing furnace steam generator includes an electric heating device 2 with a twisted resistance wire 21, a built-in dry-burning liner 1, a PLC controller, a water adding device 3, a thermocouple 22, and a steam boiler The inner chamber communicates with a steam distributor 4; the built-in dry-burning liner 1 includes a dry-burning pot 10 and a stainless steel lid 11 on the top of the dry-burning pot 10. The dry-burning pot 10 and the stainless steel lid 11 form a built-in dry-burning inner The inner tank cavity 12 of the tank 1, the bottom of the dry cooking pot 10 is provided with a thermally conductive bottom plate 13, and the bottom of the thermally conductive bottom plate 13 is provided with a thermally conductive bending card plate 14 for wrapping the annealing furnace tube row 20; the water adding device 3 includes a two-position three-way electromagnetic The valve 31, the tubular measuring cup 30, a...

Example Embodiment

[0088] Embodiment two:

[0089] Such as Figure 5 As shown, the difference from the first embodiment is that in the second embodiment of the annealing furnace steam generator, the steam introduction pipe 41 is arranged on the side of the dry burning pot 10 close to the high-temperature annealing zone 6, so that the dry burning pot 10 is close to the high temperature annealing zone 6. This structure is suitable for situations where the cooling effect of high temperature wires is the main focus. The dry burning pot 10 is arranged at the side of the high temperature annealing zone 6 close to the exit of the annealing furnace, and can utilize the heat brought from the high temperature zone by the wire to generate steam, and can help the wire cool. However, the most in need of steam protection is on the inlet side of the annealing furnace. When the steam source is on the outlet side, the amount of steam has to be increased to ensure that the inlet is effectively protected. For most w...

Example Embodiment

[0090] Embodiment three:

[0091] Such as Image 6 As shown, the difference from the first embodiment is that the steam generator of the annealing furnace described in the third embodiment is also located on the side of the built-in dry-fired inner liner 1 away from the high-temperature annealing zone 6 of the annealing furnace. The corresponding position of the bending card 14 is provided with a phase change heat preservation zone heating device 7. When this structure is used to anneal ferrous metal wires, there are strong means to control the temperature in the phase change holding zone. If the annealing furnace tube 20 has insufficient heat, it can be heated to generate steam and keep the temperature of the dry boiler 10 slightly lower than the phase change The temperature of the temperature, setting a heat preservation and heating zone on the tube row after the inner tank can better ensure that the temperature of the annealing furnace tube 201 wrapped by the thermally conduct...

Abstract

The invention relates to the technical field of steam generators, in particular to a steam generator of an annealing furnace and a control method thereof. The steam generator of the annealing furnace comprises an electric heating device twisted with resistance wires, a built-in dry combustion liner, a PLC controller, a water supply device, a thermocouple, and a steam distributor communicated with an inner chamber of a steam oven. The steam generator of the annealing furnace can better utilize heat brought by wires, avoids the waste of water and electric energy caused by overflow, improves the stability of steam, simplifies structure, is easy to operate, and reduces manufacturing cost and maintenance cost.

Description

Technical field: [0001] The invention relates to the technical field of steam generators, in particular to a steam generator for an annealing furnace and a control method thereof. Background technique: [0002] When the wire is annealed in the annealing furnace, in order to prevent the wire from being oxidized at high temperature, steam is usually used to protect the wire. The steam of the annealing furnace generally comes from the external electric heating steam generator, or from the waste heat steam generator of the enamelling machine oven. [0003] The commonly used external electric heating steam generator includes a steam generating chamber and a water level regulating water tank. An electric heating tube with a certain power is installed below the water level of the electric heating steam generator. Two pipes are connected between the steam generating chamber and the water level regulating water tank. One is connected to the underwater part, and the other is connecte...
