The box body is welded with Q235 plate, and the inner tank is welded with 314 stainless steel plate to prevent borax water from being polluted by rust, maintain the purity of borax, and maintain the effect of boron-coated steel wire. There is 40mm insulation cotton between the two layers. Stainless steel electric heating tube 12KW, with thermocouple to control the temperature, 1.5KW lifting pump used for borax water circulation, equivalent to automatic stirring, the upper layer of the tank adopts multiple overflow methods, and the high-pressure air blow at the outlet is used to adjust the steel wire The amount of borax on the surface. The length is 2500mm, the width is 500mm, the height is 1100mm, and the weight is 800Kg.
Boron-coated wire is placed between the shelling machine and the wire drawing machine when the low carbon steel wire is drawn. It does not need to be dried and is drawn directly, which increases the drawing speed by 50% and the service life of the tungsten steel mold by 100%. The steel wire can be drawn to 0.6mm without annealing, the speed is ≥30m/s, and the efficiency is obvious.
Boron-coated wire is placed between the shelling machine and the wire drawing machine when the high carbon steel wire is drawn. It needs to be dried and then drawn to ensure normal drawing and drawing.
