Abstract
The invention discloses a quenching method for stainless steel welding wires, which belongs to the technical field of metal heat treatment processes. By heating, cooling, cleaning and wire take-up, especially in the processes of heating and cooling, the strength, hardness, wear resistance and fatigue resistance of stainless steel welding wires can be enhanced, and due to the wire take-up and cleaning operations, the space can be saved.
Description
Technical field
The present invention relates to a kind of heat treating method of martensitic stainless steel wire, belong to metal heating processing technology technical field.
Background technology
Quenching metal works is heated to a certain proper temperature and keeps for some time, immerses the metal heating processing technology of cooling fast in quenching media immediately.Quenching can improve hardness and the wear resistance of metal works, is thus widely used in various work, mould, measurer and requires the part (as gear, roll, carburized parts etc.) of surface abrasion resistance.
Tradition quenching technology is long for heat-up time, and piece surface oxidation and decarbonization is more, and part scrap rate is higher.And occupation area of equipment is large, operate more loaded down with trivial details, high temperature in production process, labor condition is poor, pollutes relatively serious.
Induction quenching is the principle utilizing electromagnetic induction, makes part cutting magnetic line in alternating magnetic field, produces induced current, again according to the surface action of alternating-current on surface.With eddy currents by piece surface rapid heating, the then quenching method of chilling.Induction heating belongs to endogenous pyrogen direct heating, and thermosteresis is little, and therefore rate of heating is fast, and thermo-efficiency is high.It occupies critical role in Field of Heat-treatment, is the developing direction of following quenching technology.
Summary of the invention
For solving the problems of the technologies described above, we have proposed a kind of quenching method of stainless steel welding stick, not connecing and can solve the large problem of floor space, and it is fast to reach rate of heating, the object that thermo-efficiency is high.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of quenching method of stainless steel welding stick, comprise the following steps: (1) is heated after the martensitic stainless steel wire unwrapping wire on draw drum by an induction heating device, Heating temperature is 950 DEG C ~ 1050 DEG C, and heat-up time is 5s ~ 10s, and load coil length is 2000mm; (2) martensitic stainless steel wire after heating is cooled by a cooling oil sump; (3) martensitic stainless steel wire cooled is carried out ultrasonic cleaning by a ultrasonic cleaning pond, then again by oven for drying, oven temperature is 200 DEG C, and baking oven length is 4m; (4) martensitic stainless steel wire after cleaning, oven dry is carried out take-up by a take-up, take-up speed 20 ~ 50m/min.
Pass through technique scheme, martensitic stainless steel wire intensity, hardness, wear resistance and fatigue property after the present invention's quenching all effectively improve, thus meet the different service requirementss of various mechanical component and instrument, and production efficiency is high, part scrap rate is lower, and whole plant is compact, and floor space is little, easy to use, rate of heating is fast.
Embodiment

4, the stainless steel welding stick cooled is carried out ultrasonic cleaning by a ultrasonic cleaning pond, then again by oven for drying, oven temperature is 200 DEG C, and baking oven length is 4m;
5, the stainless steel welding stick after cleaning, oven dry is carried out take-up by a take-up, take-up speed 50m/min, can high rigidity be obtained, the target product that erosion resistance is strong.
Embodiment 2
A quenching process for stainless steel welding stick, described method comprises following processing step:
1, getting the trade mark is 420J1, and wire diameter is that the Martensite Stainless Steel welding wire of 5.0mm is positioned on draw drum;
2, heated after the Martensite Stainless Steel welding wire unwrapping wire on draw drum by an induction heating device, Heating temperature is 1050 DEG C, and heat-up time is 10s, and load coil length is 2000mm;
3, the stainless steel welding stick after heating is cooled by a cooling oil sump;
4, the stainless steel welding stick cooled is carried out ultrasonic cleaning by a ultrasonic cleaning pond, then online by oven for drying, oven temperature is 200 DEG C, and baking oven length is 4m;
5, the stainless steel welding stick after cleaning, oven dry is carried out take-up by a take-up, take-up speed 20m/min, can high rigidity be obtained, the target product that erosion resistance is strong.
The present invention carrys out the quenching requirement of the stainless steel welding stick of satisfied different wire diameter and material by the electrical parameter and take-up speed controlling induction heating device.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
