Embodiment
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See Fig. 1, the invention provides a kind of Production method for wire rod for steel wool, comprise the steps:
(1) component selections is become: wire rod for steel wool chemical composition mass percent is: C:0.06% ~ 0.15%, Si :≤0.07%, Mn:0.7% ~ 1.1%, P :≤0.030%, S :≤0.020%, this Composition Control scope is narrower, can ensure that end properties fluctuation reduces, P, S content is low, and detrimental impurity impact is little, simultaneously for improving cutting ability, P should not control too low.Little and impurity all favourable drawing and the cutting less of performance inconsistency.
(2) converter smelting: adopt 110t converter melting (being different from electrosmelting), scrap ratio controls about 10%, endpoint carbon content >=0.05%, to prevent Molten Steel over-oxidation, the impurity reducing carburelant consumption simultaneously and bring into.Tapping adopts mid-carbon fe-mn alloying, final deoxygenation uses aluminium ferromanganese, steel-core-aluminium and BaAlSi, start during tap to 1/4 to add alloy material, alloy addition sequence is steel-core-aluminium, BaAlSi, FeMnAl, mid-carbon fe-mn, in guarantee deoxidation simultaneously completely, Alt≤0.02% in steel, reduces hard inclusions total amount in steel.
(3) LF external refining: refining process adopts the refining of high alkalinity white slag, and basicity controls about 3.0, and the white slag time is not less than 15min.For preventing molten steel exposed, argon pressure should more than 0.2MPa, soft blow time >=8min, ensure that inclusion fully floats, assembles, grows up and gets rid of, the impact that minimizing is mingled with drawing and cutting.
(4) continuous casting: continuous cast billet cross-sectional dimension is 150mm × 150mm; long 12.45m; whole process protection is poured into a mould; use covering agent in square billet mould flux and low-carbon (LC); tundish superheating temperature controls at 30 ± 10 DEG C, and to reduce center segregation, pulling rate is 2 ~ 2.5m/min; in requirement process, pulling rate is steady, prevents because fluctuation causes slag and center segregation to worsen.Adopt M-EMS, reduce center segregation and loosen, M-EMS Current is 320 ~ 350A, and frequency is 4Hz.
(5) heat: during high speed wire rolling, heating adopts stepped start-stop system Two-cuff Technique two sections or three-stage heating furnace heating, heating and temperature control, at 1080 ~ 1160 DEG C, while the diffusion of promotion carbon, reducing center segregation, avoids austenite crystal too thick serious with decarburization; Start rolling temperature controls at 960 ~ 1040 DEG C; Final rolling temperature controls at 920 DEG C ~ 980 DEG C; Roll speed control built in 80 ~ 95m/s; Laying temperature is 850 ~ 900 DEG C.
(6) stelmor is air-cooled: stelmor control cold employing delaying type pattern, speed of cooling is 4 ~ 5 DEG C/s.Air door of fan complete shut-down, insulation cover is except over 1#, and all the other complete shut-downs, roller table speed is 0.12 ~ 0.18m/s, front fast rear slow.
Adopt aforesaid method produce wire rod for steel wool, Composition Control level is high, and in steel, impurity is few, be especially unfavorable for cut hard inclusions, therefore drawing and cutting ability excellent.
