Description
Technical field
The utility model relates to the heating installation in the band steel heat treatment process, refers to the multi-functional ultrafast heating installation of a kind of band steel particularly.
Background technology
The band steel is when heat-treating, and the heat-up rate of thermal treatment temperature rise period can produce certain influence to band steel heat treatment on microstructure structure.Concerning the belt steel material such as electrical steel of specific function, The faster the better to require heat-up rate, preferably can be greater than 100 ℃/S, to improve the performance quality of material.
At present, the equipment that the band steel is heat-treated adopts continuous annealing furnace usually.The type of heating of tradition continuous annealing furnace generally has or not oxidizing flame snead process, radiator tube heating method and resistive band heating method, its principle all is to utilize high temperature heat source and be heated the temperature difference of being with between the steel, will be heated to the annealing temperature of regulation with steel by radiation and thermal conduction.Realize rapid heating, just must improve the temperature difference between band steel and the high temperature heat source with steel.When the temperature of band steel was lower than 500 ℃, the temperature of high temperature heat source was generally 900～1000 ℃, and the temperature difference of the two can reach 400～500 ℃, and its rate of heating is than very fast.But when the temperature of band steel during near 800 ℃, keep the effect of rapid heating, the temperature of high temperature heat source must be controlled at 1200～1300 ℃, and this obviously is difficult to realize for traditional continuous annealing furnace.For example, in the process of electrical steel oriented silicon steel thermal treatment decarburizing annealing, adopt traditional continuous annealing furnace to carry out radiator tube, resistive band or flame direct heating, the band steel is heated to average heating speed more than 800 ℃ generally about 20 ℃/S from room temperature, is difficult to surpass 50 ℃/S.Therefore, the tradition continuous annealing furnace can only adopt the method that prolongs heat-up time to reach the annealing temperature of strip process regulation, Proper Design must be got very long like this, usually to reach 40～160m, cause that occupation area of equipment is bigger than normal, heating atmosphere is not easy to keep, heat treatment efficiency is low, production cost is higher, quality product descends.
In order to address the above problem, the scientific research personnel has changed the heat exchange pattern of traditional continuous annealing furnace in recent years, by to being with steel to carry out electromagnetic induction or directly energising heating, realizes its thermal treatment by being with steel self generation heat to heat up.Though can improve band Heat Treatment Of Steel efficient and product quality like this, but electromagnetic induction heating is after the Curie temperature (about 700～800 ℃) of belt steel material, and temperature just is difficult to further improve, and the band steel is thin more, need the frequency of energising just high more, manufacture difficulty is also very high; And directly the energising heating is to lead to power supply at the two ends of band steel, the Jiao Erre that produces when leaning on electric current by the band steel comes the heating zone steel, and reach ultrafast rate of heating needs very big electric power, and belt steel surface requires cleaning, can not residual oxide film or non-conductive coating layer, cause production cost to increase.
How do not changing existing output strip line basically, do not increasing the deficiency that overcomes above-mentioned traditional technology and abbreviated system under the situation of production cost, and high efficiency production goes out high-quality band steel, become the difficult problem that the scientific research personnel is badly in need of solving.
Summary of the invention

Alternatively, the heating furnace body of described direct electric heating device is arranged on before the induction body of heater of described electromagnetic induction heater or afterwards, the pair of conductive roller of described direct electric heating device is arranged on the two ends of described heating furnace body.
Preferably, the shared induction body of heater of described direct electric heating device and electromagnetic induction heater, the pair of conductive roller of described direct electric heating device is arranged on the two ends of described induction body of heater.
Compare with the band steel heat-treatment production line of existing single electromagnetic induction or directly energising, the utlity model has following advantage:
(1) electromagnetic induction and two kinds of type of heating of direct energising are combined into one, both synergies, can significantly improve the heating efficiency in the unit time, short-term rate of heating to the band steel can reach 100～1000 ℃/S, and directly the power of energising needn't be very high, so can realize the miniaturization of Equipment for Heating Processing.
(2) owing to the raising of heating efficiency, heating procedure is of short duration, and required heating atmosphere also keeps easily.
(3) thermal inertia of band steel is less, and the band steel annealing process of different varieties specification switches very simple.
(4) electromagnetic induction and directly switching on to the automatic controlling level height of belt steel temperature is convenient to realize required processing requirement.
(5) electromagnetic induction and the two kinds of type of heating of directly switching on can be used in combination, and also can use separately, by the mutual lotus root relation of closing of adjustment energising heating and induction heating and the rational Match of power efficiency, realize the multifunction of this equipment.As for scribbling the band steel of insulation layer or oxide film, can carry out the thermal treatment that processing requirement is finished in the laggard electrically heated that works of induction heating earlier.
In summary, the utility model can make device length shorten greatly owing to accelerated band Heat Treatment Of Steel speed, and production efficiency significantly improves, production cost greatly descends, product quality effectively improves.Particularly aspect the processing of silicon ribbon steel heat Special Significance is being arranged, can effectively promote the quality of silicon steel product.
