Description
Technical field
The utility model relates to smelting equipment technical field, especially relates to a kind of middle frequency furnace.
Background technology
Middle frequency furnace is a kind of supply unit power frequency 50HZ alternating current being changed into intermediate frequency (more than 300HZ is to 10000HZ), is made up of a few parts such as converter plant, body of heater, vermicularizing control.Middle frequency furnace is the general principle according to electromagnetic induction, direct current is become after three-phase main-frequency AC rectification, again direct current is become adjustable electric current of intermediate frequency, (coil and electric capacity can be in parallel to supply the load be made up of electric capacity and induction coil, also can connect), in induction coil, produce the highdensity magnetic line of force, and cut the metal material held in induction coil, in metal material, produce very large eddy current.Very easily to there is furnace temperature in existing middle frequency furnace too high and wear stove in smelting process, and the molten steel of outflow contacts with water blasts, and brings massive losses to production.
Utility model content
The utility model overcomes shortcoming of the prior art, provides a kind of security high, can effective monitoring furnace body temperature at the middle frequency furnace of the too high alarm of furnace temperature.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of middle frequency furnace, comprises body of heater, is arranged at the bell of body of heater upper end, be arranged at the converter nose of body of heater upper end avris, and be arranged at the induction coil in body of heater; It also comprises the support body be fixedly installed on furnace body outer wall, multiple infrared temperature-sensing probe be installed on support body, be installed on the alarm on support body, the signal relay of connecting with induction coil supply line, and the controller being electrically connected infrared temperature-sensing probe, alarm and signal relay; Described support body comprises two and is fixedly installed on the peripheral and annulus of interval furnace body outer wall certain distance of body of heater respectively by contiguous block, and many uniform settings and connect the vertical bar of two annulus; Described infrared temperature-sensing probe is uniform to be installed on vertical bar and towards body of heater wall; When the temperature that any one infrared temperature-sensing probe detects exceedes setting value, controller controls alarm equipment alarm, and control signal relay cuts off.
Preferably, described contiguous block is connected with body of heater by bolt.
Preferably, described contiguous block and annulus are welded to connect.
Preferably, described vertical bar and annulus are welded to connect.
Compared with prior art, the utility model tool has the following advantages:
The utility model can carry out effective monitoring to the heating position of body of heater, give the alarm in the very first time that discovery furnace body temperature is too high and cut off the power supply of induction coil in time, avoid body of heater Yin Wendu too high and wear stove, guaranteeing the safety of producing, reducing the risk that middle frequency furnace is produced.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
