Description
Technical field
The utility model belongs to the technical field of heating of its raw material pipe in alloy steel pipe production, and what relate generally to is a kind of steel alloy pipe Medium frequency induction samming stove.
Background technology
The traditional heating mode of producing at present alloy steel pipe pipe is: adopt gas-fired furnace-sloping hearth furnace heating pipe.This technique falls behind, and seriously polluted, the lime-ash especially producing in production process, coke tar refuse and phenolic wastewater, be difficult to thorough processing, do not meet the standard of national environmental protection policy.Furnace temperature is inhomogeneous, and temperature is wayward, ferric oxide skin depth; Need artificial constantly stirring, hand labor intensity is large, and floor space is large.Because coal gas is explosive, there is potential safety hazard simultaneously.And can not reach the production object of environmental protection.In order to overcome above all drawbacks, a kind of device of the heating of the method by Frequency Induction Heating pipe has been proposed in industry at present, principle be by the pipe of needs heating as in spiral ruhmkorff coil, pipe, under action of alternating magnetic field, produces induced current and generates heat in pipe.According to the equipment of this technology manufacture, also there is certain shortcoming, adopt consistent formula to arrange, due to discharging and pan feeding point-blank, and there is velocity contrast, always cause pipe head and tail temperature difference excessive, can only enter a material, go out a material, once and occur abnormal, stove need to be cut off, need to again start shooting, increase energy consumption, and electrical network is produced and impacted, and without the abnormal ability of appearance of tackling subsequent production line; Owing to having adopted induction heating, rate of heating is very fast, although induction furnace itself is provided with samming section, in order to meet quantity-produced needs samming for a long time simultaneously; Because steel alloy is will the time than ordinary steel long in the samming time in when heating, therefore the process furnace of this consistent formula layout, can not make the good samming of steel alloy.In order to address these problems, general samming stove is resistance-type samming stove in the market, by resistive heater, by thermal radiation and thermal convection, heat samming pipe, because its resistance wire needs often to change, the structure of its design can not be fully-closed, therefore easily cause furnace sealing poor, furnace temperature is inhomogeneous, and temperature is wayward, samming process ferric oxide skin depth.Stove needs more than 2 hours, to need first preheating samming stove start time simultaneously, then could use.Consume energy high, and can not tackle short run and produce fast.
Summary of the invention
The purpose of this utility model is for overcoming shortcomings and deficiencies of the prior art, a kind of steel alloy pipe Medium frequency induction samming stove is provided, can realize hermetically sealed, the opening that whole body of heater contacts with air is little, iron scale is few, and heating process temperature is even, and easy control of temperature and heat-up time are fast, do not need preheating samming stove, at any time can open and close.
The utility model completes the technical scheme adopting with foregoing invention task:
A steel alloy pipe Medium frequency induction samming stove, described samming stove includes: Medium frequency induction samming furnace body, feed mechanism, charging mechanism and discharging mechanism; Described Medium frequency induction samming furnace body is that insulated shell forms, and on described insulated shell, is fixed with retaining plate, and ruhmkorff coil is fixed on insulated shell by retaining plate; Wherein, described ruhmkorff coil is rectangular framework, is provided with refractorily lined and on refractorily lined, is fixed with high temperature resistant guide rail in described ruhmkorff coil, and described high temperature resistant guide rail is be arranged side by side a plurality of; The upper surface of described high temperature resistant guide rail is inclined-plane, be described high temperature resistant guide rail upper surface for by feed zone to discharging section downward inclined-plane gradually, with the self-closing feeding gate of spring and feed zone and the discharging section setting in the corresponding body of heater of self-closing discharge door difference, and be separately fixed on the insulated shell of both sides; Described feed mechanism, discharging mechanism are positioned at the same side of Medium frequency induction samming furnace body corresponding described self-closing discharge door, the setting of self-closing discharge door respectively; Described charging mechanism is arranged on one end of the feed zone of Medium frequency induction samming furnace body.
The utility model compared with prior art, has following beneficial effect:
The utility model can be realized quick samming or heating, tackles fast small serial production, and start, to going out first qualified temperature pipe, only needs the time of several minutes; By structure design of the present utility model, while only having turnover bin gate, there is contacting of short period of time with air, high temperature pipe is contacted with air greatly and reduce, avoid scattering and disappearing and can guaranteeing that in stove, temperature is even of furnace heat; The generation that has reduced pipe ferric oxide when high temperature samming, has further reduced scaling loss, improves the outer surface quality of product.Structure design of the present utility model can make body of heater can pack two into material loading, carries out samming simultaneously, and the samming time lengthens, and heat is transmitted more even, effective, and the core table temperature difference is no more than 10 degree end to end.In subsequent production, occur when abnormal, can accomplish need not shut down in the short period of time.
