Accompanying drawing explanation
Fig. 1 is nickel strap thermal treatment unit schematic diagram of the present invention.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, a kind of nickel strap thermal treatment unit that the present invention proposes, comprising: unreeling machine 1, front carrying roller 21, protective gas inner bag 3, heat treatment furnace body 4, temperature control element 5, frame 6, refrigerating unit 7, rear carrying roller 22, winder 9; Refrigerating unit 7 is arranged in frame 6.
Unreeling machine 1 is for placing pending rolling nickel strap 8; Carrying roller 21, heat treatment furnace body 4, refrigerating unit 7, rear carrying roller 22, winder 9 before establishing successively after unreeling machine 1.Heat treatment furnace body 4 inner transverse installs protective gas inner bag 3, and protective gas inner bag 3 extends in refrigerating unit 7, and the two ends of protective gas inner bag 3 expose the heat treatment furnace body 4 of front end and the refrigerating unit 7 of rear end respectively; At the outer side of protective gas inner bag 3, temperature control element 5 is installed.One or more heating zone 41 is provided with at heat treatment furnace body 4 inner bottom part.
This unreeling machine 1 and winder 9 all adopt Manual expansion mechanism, and unreeling machine 1 and winder 9 are equipped with tightening pulley, and rolling nickel strap 8 is sleeved on tightening pulley and by the harmomegathus of tightening pulley and is fixed.The minimum diameter of tightening pulley is 320mm, and maximum diameter is 345mm.Unreeling machine 1 is unpowered device, winder 9 is by power drive mechanism rolling.Front carrying roller 21 and rear carrying roller 22 are all that bearing is installed at two ends, and level is fixed, flexible rotation.
Heat treatment furnace body 4 refractory material laying, inner installation protective gas inner bag 3, in refractory material laying under protective gas inner bag 3, an electric heating element is housed, such as ribbon heater or nichrome wire, thus forms several heating zone 41 at heat treatment furnace body 4 inner bottom part; Each heating zone 41 of heat treatment furnace body 4 inner bottom part and temperature control element 5 one_to_one corresponding above it, make the temperature-controllable of heating zone 41, conveniently set furnace temperature.Temperature control element 5 can adopt thermopair.
