Embodiment 1
[0058] A steel rail cladding alloy method without cooling rate control, comprising the following steps:
[0059] a. Place the rail cladding machine on the rail, the plasma welding torch 10 on the rail cladding machine moves at a constant speed with the first mobile trolley 1, and the plasma welding torch 10 cladding alloy above the rail head tread surface to be clad;
[0060] b. The alloy strip formed after alloy cladding is located on the inner side of the center of the rail head tread, the width of the alloy strip is 4mm, and the thickness of the heat-affected zone of the rail is controlled at 0.3mm;
[0061]c. Arrange the flame head 20 on the rail cladding machine above the alloy strip after cladding; use the mixed gas formed by liquefied gas and oxygen as the heating gas source, and mix the liquefied gas and oxygen directly on the flame head 20; cladding After the final alloy strip is left to stand for 2 seconds, start to move the flame head 20 at a constant speed along th...
