Abstract
The utility model relates to an electric heating furnace drying device used for an intermediate frequency furnace. The electric heating furnace drying device comprises a platy base and an electric heating tube, wherein the electric heating tube is fixed on the platy base; when the electric heating furnace drying device is used, an operator firstly slowly and safely places the electric heating furnace drying device into the intermediate frequency furnace, then the electric heating furnace drying device is powered on, and after power-on and continuous drying for 72 or more than 72 hours (depended on specification and size of the intermediate frequency furnace), the electric heating furnace drying device is powered off and taken out, and then production and smelting can be carried out; therefore, when an intermediate frequency furnace host machine controls production and smelting of one intermediate frequency furnace, another intermediate frequency furnace connected with the intermediate frequency furnace host machine can be dried by virtue of the electric heating furnace drying device, normal production is not influenced, and further the problem that the efficiency for drying the intermediate frequency furnace is low in the prior art is solved.
Description
Technical field
The utility model relates to the servicing unit technical field of the intermediate frequency furnace that is used for metal smelt, relates in particular to a kind of intermediate frequency furnace with electrical heating baker device.
Background technology
Intermediate frequency furnace has another name called the intermediate frequency coreless induction furnace, is the key equipment that coloured at present and ferrous metal etc. are cast and smelted, because its burn-off rate is fast; The metallic element scaling loss is few, and the saving electricity charge are obvious, and noise is low; Low in the pollution of the environment, characteristics such as safe and reliable are widely applied by industry both at home and abroad.The intermediate frequency furnace liner is commonly called as flue or crucible, is to form with the refractory material ramming, must the liner crucible that ramming becomes be toasted → dry before using → sintering after, can come into operation.After using certain hour, the new furnace lining crucible of ramming again after must old furnace lining being removed, and then will new furnace lining baking → oven dry → sintering → regeneration product melting, carry out the work production melting so again and again.
Past is the baker process to the baking → oven dry → sintering of intermediate frequency inner lining of furnace material, mainly is to use intermediate frequency furnace main frame self baker (medium and small intermediate frequency furnace power supply be generally 380V-660V and with first-class), and the intermediate frequency furnace main engine power is big on the one hand, and power consumption is big; The intermediate frequency furnace that adopts at present on the other hand is the circuit arrangement (promptly a main frame supplies two middle frequency furnaces) of one drag two mostly, during as if the production melting, can not carry out baker to another intermediate frequency furnace; If during baker, then can't carry out the production melting, influence the raising of production efficiency.
The utility model content
The utility model provides a kind of intermediate frequency furnace convenient to operation with electrical heating baker device, be intended to solve the inefficient problem of the baker of intermediate frequency furnace in the prior art.
This intermediate frequency furnace is following with the technical scheme of electrical heating baker device:
A kind of intermediate frequency furnace is with electrical heating baker device, comprises by refractory material being used to of processing being installed in the tabular pedestal in the adaptive intermediate frequency furnace crucible, is fixed with on the said tabular pedestal to be used for the electric heating tube that the furnace lining to intermediate frequency furnace toasts.
Said electric heating tube is a U type electric heating tube.
Being shaped as of said tabular pedestal is discoideus, and said electric heater has three, and evenly is laid on the said tabular pedestal around circumferencial direction.
Said tabular pedestal is high-temperature insulation plate or high temperature resistant steel plate or cement asbestos board.
The baker device is made up of tabular pedestal and electric heating tube in the utility model, and electric heating tube is fixed on the tabular pedestal, in use; The operator slowly and safely inserts electric heating baker device in the intermediate frequency furnace earlier, and energized treats that energising baking continuously is about more than 72 hours or 72 hours back (looking intermediate frequency furnace specification, size decision) then; Cut off the electricity supply again, take out the baker device, can carry out the production melting; Thereby make the intermediate frequency furnace main frame when intermediate frequency furnace of control carries out the production melting; Another intermediate frequency furnace that is connected with this intermediate frequency furnace host computer control can toast through this baker device, and does not influence ordinary production, and then has solved the inefficient problem of the baker of intermediate frequency furnace in the prior art; Simultaneously, this intermediate frequency furnace also has the following advantages with electrical heating baker device:
1, simple in structure, be convenient to operation;
2, in the baker process, heating-up temperature or programming rate are even, constant temperature, the extraordinary heating curve of having controlled, and do not need personnel's field tracking to control, simple and easy to do.And adopt intermediate frequency furnace main frame baker, answer low-temperature bake in the early stage, in interim temperature dry; The later stage high temperature sintering, and the personnel of need followed the tracks of regulation and control, technology not only complicacy but also waste of manpower resource in 24 hours; Thereby make baker process staff's labour intensity reduce, make the effect of baker improve;
3, in the baker process,, effectively avoided or fundamentally solved the unstable furnace lining cracking that is prone to cause that heats up, the service life of having improved furnace lining because ascending temperature is even or constant temperature;
4, intermediate frequency furnace be if being interrupted when producing, can put into the preheating of baker device in advance, heats up too fast when having avoided production and wears stove, thereby improved the service life of furnace lining;
5, when the one drag two intermediate frequency furnace is produced, if the body of heater of an intermediate frequency furnace is worn stove, another intermediate frequency furnace can put into production at once, has saved the production time, has improved production efficiency;
6, compare with adopting intermediate frequency furnace main frame roast technic, practice thrift the electricity charge, energy-saving effect is obvious.
