Embodiment Construction
[0015] The method of the present invention is adopted in the continuous annealing simulation experiment machine of cold rolled strip steel, and the details are as follows.
[0016] Such as figure 1 As shown, the sample 1, the fixture 2, the infrared heating devices 5, 6, 7, and 8 are all placed in the operation box 11, and the operation box 11 can be evacuated or filled with various protective atmospheres; the fixture 2 and the heating transformer 3 The sub-levels are connected by a 20×100mm copper bar. Sample 1 is a 1.0×300×560mm cold-rolled strip steel, with 50mm at both ends being clamped in the fixture 2, and the width of the opening of the reflector 10 is 50mm , The reflector 10 is fixed on the wall of the operation box 11, arranged vertically and symmetrically on the sample 1 up and down, the opening is 100mm away from the surface of the sample 1, and the outermost edge is 30mm away from the fixture 2. Infrared heating device The infrared light-emitting lamps 9 in 5, 6 and ...
