Description
Affiliated technical field
The present invention belongs to the alloy group in International Patent Classification (IPC), i.e. C22C particularly is used to make the stainless material of Flat Steel Heald or dropper.
Background technology
At present, loom adopts in the national standard stainless material of the existing trade mark mostly with the production of Flat Steel Heald and dropper, as 2Cr13 etc.Because the singularity of weaving process, especially in the weaving of water jet loom, work under bad environment, conventional stainless material can not well satisfy wear-resisting, antirust, corrosion resistant requirement.
Summary of the invention
The purpose of this invention is to provide a kind of stainless material that is used to make Flat Steel Heald or dropper.
Disclose new technical scheme, comprise the technology that it is rolled into steel band: it is characterized in that chemical ingredients composition weight percent is: chromium Cr12-15, manganese Mn0.15-0.35, nickel 0.5-0.7, titanium Ti0.1-0.3, molybdenum Mo0.1-0.3, tungsten Wu0.2-0.3, copper Cu0.05-0.1, tin Sn0.005-0.01, niobium Nb0.005-0.01, carbon C0.1-0.25, silicon Si0.1-0.25, aluminium Al≤0.01, sulphur S≤0.005, phosphorus P≤0.005, plumbous Pb≤0.0001, arsenic As≤0.0005, iron Fe surplus.
The rolling technology that above-mentioned stainless material is rolled into steel band is:
Hot rolling will be smelted after the effective element preparation, and the time is 2-3 hour; After chemical analysis meets said ratio, carry out continuous casting and rolling; First excision exterior part of ingot portion, in 1400-1500 ℃ electrochemical kitchen range formula stove castingization 10-15 minute; Come out of the stove and carry out continuously hot rolling after forging, make the thick steel band of 2.5mm, this moment, material hardness was HV200-250.
Cold rolling, after the thick steel band after the hot rolling carries out pickling, polishing, carry out cold rollingly several times, make the thin steel band of 0.8mm, carry out clean annealing 1-3 time in the cold-rolled process and during cold rolling end, temperature is 700-750 ℃.
Finish rolling is cold rolled to manufacturing Flat Steel Heald or the required thickness of dropper, each cold rolling minimizing thickness 0.08-0.1mm with thin steel band several times with different rolls.
Compared with the prior art stainless material and product according to such scheme is made, have better wear-resisting, antirust and erosion resistance.
Embodiment
The chemical ingredients of setting according to the present invention is formed weight percentage ranges, with vacuum induction furnace smelting 2-3 hour, after chemical analysis meets proportioning, carry out continuous casting and rolling, carry out hot rolling, cold rolling, finish rolling respectively by above-mentioned technology when rolling, make the steel band of producing Flat Steel Heald or dropper.
Embodiment 1:
The chemical ingredients of setting according to the present invention is formed weight percent, behind the preparation effective element, smelts 2 hours 30 minutes in vacuum induction furnace, is cast into steel ingot after chemical analysis is qualified.With hot steel ingot castingization 10 minutes in 1500 ℃ of electrochemical kitchen range formula stoves, forge after coming out of the stove and continuously hot rolling, make the thick steel band of 2.5mm, material hardness is HV210-230.Steel band after the hot rolling is carried out carrying out cold rollingly after pickling, the polishing, when being rolled to the steel band of 1.8mm, carry out clean annealing one time, temperature is 750 ℃.Annealing back is continued rolling, when being rolled to the thin steel band of 0.8mm, carries out clean annealing again one time, and temperature is 700 ℃.Carry out finish rolling then, the thin steel band of 0.8mm is divided to be cold rolled to for five times with different rolls make the required thickness 0.3mm of Flat Steel Heald, each cold rolling minimizing thickness 0.1mm, material hardness is HV320-350.
Embodiment 2:
The chemical ingredients of setting according to the present invention is formed weight percent, behind the preparation effective element, smelts 2 hours 30 minutes in vacuum induction furnace, is cast into steel ingot after chemical analysis is qualified.With hot steel ingot castingization 12 minutes in 1450 ℃ of electrochemical kitchen range formula stoves, forge after coming out of the stove and continuously hot rolling, make the thick steel band of 2.5mm, material hardness is HV200-220.Steel band after the hot rolling is carried out carrying out cold rollingly after pickling, the polishing, when being rolled to the steel band of 1.8mm, carry out clean annealing one time, temperature is 730 ℃.Annealing back is continued rolling, when being rolled to the thin steel band of 0.8mm, carries out clean annealing again one time, and temperature is 700 ℃.Carry out finish rolling then, the thin steel band of 0.8mm is divided to be cold rolled to for four times with different rolls make the required thickness 0.4mm of Flat Steel Heald, each cold rolling minimizing thickness 0.1mm, material hardness is HV300-330.
Because pickling, polishing, clean annealing are routine techniques, the description is here omitted.
