Technical field
The present invention relates to nonferrous materials processing technique field, especially a kind of ferro-aluminum nickelbronze extrudes bar preparation technology.
Background technology
Xantal has high mechanical property, anti-corrosion, wear-resisting, cold-resistant, flower of not lighting a fire during impact, good fluidity, and segregation tendency is little, obtains sound casting.Traditional technology is: ingot casting-heating-extruding-aligning-flaw detection-technique center special furnace quenching-tempering process is produced, and squeezes excellent φ 120 for ideal format: technique ingot casting 360*500 extrudes φ 120-aligning-flaw detection-technique center quenching-tempering-flaw detection.In actual production, due to technique center quench aging ageing equipment, squeeze excellent tempering rear surface and press against wound, bending, and after tempering, flaw detection does not conform to, and causes yield rate on the low side, less than 10%, and cost remains high, and is difficult to delivery date ensure.
In view of the foregoing, now develop a kind of ferro-aluminum nickelbronze and extrude bar preparation technology.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of ferro-aluminum nickelbronze is provided to extrude bar preparation technology, change traditional Q-tempering preparation technology, namely Q-tempering is carried out at specific equipment after extruding, directly quench treatment is completed at extrusion process, i.e. press quenching process, the present invention adopts press quenching technology at xantal product first, adopt suitable extrusion temperature, extrusion speed, the tensile strength of material is significantly improved after process, yield strength, hardness, meet product high performance requirements, thus shortened process greatly, improve yield rate.
The present invention to achieve these goals, adopts following technical scheme: a kind of ferro-aluminum nickelbronze extrudes bar preparation technology, and technical process is: founding → extruding also press quenching → sawing → aligning → pickling → tempering → flaw detection → packaging warehouse-in;
The first step, founding: use medium-frequency induction furnace to carry out melting and casting ingot blank, casting temperature: 1100 ~ 1300 DEG C, casting speed: 2.0 ~ 8.0m/h, be cast as the ingot casting of setting specification;
Second step, extruding is press quenching also: use 3000 tons or 3150 tons or 4000 extrusion machines to extrude, extrusion process adopts decortication mode, ingot casting Heating temperature: 700 ~ 950 DEG C, extrusion speed: 10 ~ 30mm/s, extrusion ratio: 9 ~ 30, remaining thickness: the 35 ~ 50mm of pressure, the ingot casting of the process furnace heating of attaching troops to a unit through extrusion machine is pushed in the container of extrusion machine, extrusion axis extrudes ingot casting and flows out through mould outlet, extrudes directly to carry out quench treatment, i.e. press quenching afterwards, the time of press quenching is 3 ~ 8 minutes, makes the excellent base of setting specification;
3rd step, sawing: use sawing machine to cut off end to end the excellent base after press quenching;
4th step, aligning: the excellent base through sawing is placed on straightener and carries out aligning processing;
5th step, pickling: the excellent base after aligning is put into sulfuric acid tank and carried out pickling;
6th step, tempering: adopt electric resistance annealing stove to the excellent base temper through pickling, the annealing temperature of tempering process: 500 ~ 700 DEG C, soaking time: 50 ~ 150min;
7th step, flaw detection: ultrasonic wave visits rear obtained rod product entirely;
8th step, packaging warehouse-in: carry out packaging warehouse-in by customer requirement to after rod product surface degreasing.
The invention has the beneficial effects as follows: the present invention is ferro-aluminum nickel system bronze, and iron can make the atomic diffusion rates in xantal slow down, and increases the stability of β phase." self-annealing " phenomenon causing alloy to become fragile can be suppressed, significantly reduce alloy fragility, can also crystal grain after the casting of refinement xantal or recrystallize, improve mechanical property.Add nickel, improve the temperature of xantal eutectoid transformation, make again eutectoid point composition move to high alumina direction, change α phase shape.Nickel significantly improves the intensity of xantal, hardness, thermostability and solidity to corrosion.This alloy is quad alloy, and the content of Aluminum in Alloy, nickel, iron and each other ratio, alloy heat-treat condition (quenching temperature, speed of cooling, tempering temperature and time etc.) all affect precipitation form mutually and the mechanical property of alloy.The ferro-aluminum nickel system bronze bar that my company produces, specification φ 20 ~ φ 150mm, chemical composition will ask for an interview to table 1.
Table 1
The present invention adopts press quenching technology at xantal product first, adopts suitable extrusion temperature, extrusion speed, meets product high performance requirements, thus shortened process greatly, improve yield rate.Reduce energy consumption simultaneously, further reduce production cost; The specification limit of the vertical bar product adopting this processing method to produce: φ 20 ~ φ 120mm, its tolerance of dimension meets YS/T649-2007, and performance meets customer specification, and performance requriements is in table 2.
Table 2
The present invention changes traditional Q-tempering preparation technology, namely Q-tempering is carried out at specific equipment after extruding, directly quench treatment is completed at extrusion process, i.e. press quenching process, the present invention adopts press quenching technology at xantal product first, adopt suitable extrusion temperature, extrusion speed, the tensile strength (Rm) of material is significantly improved after process, yield strength (Rp0.1), hardness (HB), meets product high performance requirements, thus shortened process greatly, improve yield rate.The water seal that this technology is different from fine copper and some alloys extrudes, fine copper alloy its objective is grain fineness number in order to improve material and reduces surface oxidation, high-performance ferro-aluminum nickelbronze bar on-line quench treatment, its object, in order to improve the mechanical property of material, meets material high performance requirements.Excellent φ 120 is squeezed: novel process: the press quenching φ 120-aligning-tempering-flaw detection of ingot casting Φ 300 ~ 400*500 ~ 600 for ideal format.φ 45, φ 47, φ 40 equal-specification are extended at present.
