Abstract
The seamless welding wire with alloy core is made up through such technical steps as filling alloy powder into low-carbon seamless steel tube by vibrating, plugging both ends of tube with low-carbon steel, heating in MF induction furnace, coarse and refine rollings to form welding wire of 8 mm in diameter, coiling, pickling, coating lime or soap liquid, and drawing into 1.2-4mm welding wire. It features high productivity and uniform chemical components.
Description
The present invention relates to the Steel Wire Products Industry manufacturing and produce the seamless welding wires with alloy core technology, specifically: it relates to a kind of manufacture method of seamless welding wires with alloy core.
Background technology of the present invention generally is to adopt solder flux is inserted in the seamless steel pipe that diameter is 10～20 millimeter, finishes the welding wire manufacturing through technical process such as pickling, heat treatment, drawing, plating then, and this manufacture method exists following shortcoming and deficiency:
1. solder flux is filled difficulty, and equipment is numerous and diverse and fill inhomogeneous when seamless steel pipe is longer;
2. many to the end product drawing passage from blank, efficient is low, intermediate annealing often, the cost height;
3. charging apparatus complexity is invested greatlyyer, therefore is necessary to occur a kind of manufacture method that can overcome a kind of seamless welding wires with alloy core of above-mentioned deficiency.
The manufacture method that the purpose of this invention is to provide a kind of seamless welding wires with alloy core.Solve solder flux and fill difficulty, fills inhomogeneous, manufacturing process is complicated, production cost is high, dish weighs shortcomings such as little, it is easy to make it reach manufacturing process, boost productivity, cost is low, and that solder flux is filled is convenient, evenly, the finished product welding wire in use guaranteed overlay cladding chemical composition evenly.
The object of the present invention is achieved like this: with wall thickness is 8～12 millimeters, diameter is that 60 millimeters, length are that 1.5～7.0 meters low-carbon (LC) seamless steel pipe blank carries out surfaces externally and internally pickling, flaw detection, cutting to length, make it reach no internal injury, non-scale, no grease, the alloy core powder that sintering is prepared adopts mechanical vibration method to insert in the low-carbon (LC) seamless steel pipe blank, the mild steel plug is adopted on both sides, need stay 2～6 diameters on the plug is 0.5～2.0 millimeter pore, and plug thickness is 3.0～10 millimeters.
The low-carbon (LC) seamless steel pipe blank of above-mentioned adding alloy core powder is heated through intermediate frequency furnace, and temperature is controlled at 1000 ℃～1200 ℃, 2～5 minutes time, be heated to guarantee the steel wall, and inner alloy core powder temperature is lower.After low-carbon (LC) seamless steel pipe blank after the heating sent into the three-roller planetary rolling mill roughing, take-up one-tenth dish after many sorties of y-type rolling mill tandem rolling, finish rolling become diameter to be 8.0 millimeters welding wire wire-rod rolls again.
The welding wire drum that above-mentioned finish rolling is become is drawn into diameter after overpickling, lime or soap lye coating be 1.2～4.0 millimeters finished product welding wire, this welding wire packed through adopting the thermoplastic packing machine after copper plating treatment, in case the copper plate oxidation.
The drawing of accompanying drawing is described as follows:
Fig. 1: low-carbon (LC) seamless steel pipe blank filler alloys core powder, plug trailing flank profile.
Fig. 2: seamless alloy core finished product welding wire front elevation.
The invention will be further described below in conjunction with accompanying drawing: Fig. 1 is a low-carbon (LC) seamless steel pipe blank filler alloys core powder, plug trailing flank profile, wherein (1) is low-carbon (LC) seamless steel pipe blank, the middle alloy core powder (2) that adopts the mechanical oscillation method to fill, both sides are mild steel plug (3), its thickness is 3.0～10 millimeters, and it is 0.5～2.0 millimeter passage (4) that 2～6 diameters are left in the centre.
Above-mentioned low-carbon (LC) seamless steel pipe blank is heated, and it is 1.2～4.0 millimeters finished product welding wires that rolling, pickling and lime or soap lye coating, drawing, copper facing manufacture diameter, the outer surface copper plate (5) of seamless alloy core finished product welding wire shown in Figure 2.
The present invention compared with prior art has following advantage:
(1) because low-carbon (LC) seamless steel pipe blank internal diameter is bigger, and the alloy core powder packed is easy, and fills evenly;
(2) adopt that rolling low-carbon (LC) seamless steel pipe blank is rolled into diameter is 8.0 millimeters wire rod of welding wires, the drawing amount has been lacked in letter, and production efficiency height, lumber recovery height, cost, dish are great, and technology is simple, adopts common apparatus, is convenient to promote.
