Kev tsim khoom:
Raws li kev tsim khoom sib txawv, nws tuaj yeem muab faib ua cov raj kub dov, cov raj txias txias, cov raj txias txias, cov raj extruded (1) Kub dov seamless kav feem ntau tsim los ntawm cov yeeb nkab tsis siv neeg dov mills. Tom qab cov khoom siv tau raug tshuaj xyuas thiab qhov tsis xws luag raug tshem tawm, nws raug txiav mus rau hauv qhov ntev yuav tsum tau, nyob rau hauv lub perforated kawg lub ntsej muag ntawm lub raj, thiab ces xa mus rau lub cua sov rauv rau cua sov thiab perforated nyob rau hauv lub perforator. Thaum perforating, nws tig thiab txav mus rau pem hauv ntej tsis tu ncua. Nyob rau hauv qhov kev txiav txim ntawm cov rollers thiab lub taub hau, ib kab noj hniav yog maj mam tsim nyob rau hauv lub raj, uas yog hu ua ib tug ntxhib raj. Tom qab ntawd nws raug xa mus rau cov yeeb nkab tsis siv neeg dov zeb rau kev dov ntxiv. Thaum kawg, phab ntsa tuab yog kho los ntawm lub tshuab leveling, thiab txoj kab uas hla yog txiav txim siab los ntawm lub tshuab sizing kom tau raws li qhov yuav tsum tau ua. Kev siv cov raj txuas txuas txuas ntxiv los tsim cov kav dej kub dov seamless steel yog ib txoj hauv kev zoo dua.
(2) Yog tias koj xav tau cov kav dej seamless nrog qhov me me thiab zoo dua, koj yuav tsum siv lub tshuab txias txias, kos duab txias lossis ua ke ntawm ob. Txias dov feem ntau yog ua los ntawm ob-yob dov zeb, thiab cov yeeb nkab steel yog dov rau hauv lub nplhaib-zoo li lub qhov uas muaj qhov sib txawv ntawm qhov sib txawv-section ncig lub qhov zawj thiab lub taub hau conical nyob ruaj ruaj. Kev kos duab txias feem ntau yog ua los ntawm ib lub voj voog ib zaug lossis ob lub saw txias txias tshuab nrog lub peev xwm ntawm 0.5 txog 100 tons.
(3) Cov txheej txheem extrusion yog muab lub raj cua sov tso rau hauv lub tog raj kheej kaw extrusion, thiab tus pas nrig perforating txav ua ke nrog tus pas nrig extrusion kom extrude qhov extruded los ntawm qhov me me tuag. Txoj kev no tuaj yeem tsim cov kav hlau nrog cov kab me me.
Kev kho cua sov
Kev kho cua sov ntawm seamless steel kav: annealing, normalizing, tempering, quenching; Kev ua tiav cov kev cai ntawm cov khoom siv kho tshuab los ntawm cov txheej txheem kev kho cua sov sib txawv yog qhov tseem ceeb hauv kev lag luam seamless steel yeeb nkab. Cov nram qab no luv luv qhia txog ntau yam seamless steel yeeb nkab kev kho cua sov txheej txheem.
Annealing: Seamless steel yeeb nkab kev kho cua sov txheej txheem nyob rau hauv uas seamless steel yeeb nkab yog maj mam rhuab mus rau ib tug tej yam degree, khaws cia rau ib tug txaus lub sij hawm, thiab ces txias ntawm tus nqi tswj. Nws feem ntau muab faib ua tiav annealing thiab tsis tiav annealing.
Lub hom phiaj ntawm annealing: Annealing tuaj yeem kho cov qauv sab hauv ntawm seamless steel kav, tshem tawm cov txheej txheem tsis xws luag, txo qhov hardness ntawm seamless steel kav, txhim kho kev ua tau zoo, tshem tawm cov kev ntxhov siab nyob hauv cov kav dej seamless steel, stabilize cov specifications ntawm seamless steel kav, thiab txo deformation. thiab tawg nyiam.
Normalizing: Kub lub seamless steel yeeb nkab rau 727 degree rau 912 degree los yog 30 ~ 50 degree saum toj no qhov tseem ceeb kub ntawm austenite, cia nws sov rau ib lub sij hawm ntawm lub sij hawm, tshem tawm ntawm lub cub tawg thiab txias nws nyob rau hauv cov huab cua. Ua kom cov nplej refinement thiab carbide faib ntawm seamless steel kav sib xws kom ua tiav lub hom phiaj ntawm kev txhim kho cov cuab yeej cuab tam (nce elongation).
Lub hom phiaj ntawm normalizing: Tom qab normalizing, lub hardness ntawm tsawg-carbon seamless steel kav yog me ntsis siab dua li ntawm annealing, thiab lub toughness kuj zoo dua; normalizing ntawm nruab nrab-carbon seamless steel kav yuav hloov quenching thiab tempering (quenching + high-temperature tempering) kev kho mob. Lub hardness ntawm seamless steel yeeb nkab tom qab normalizing yog nruab nrab, lub toughness yog zoo, thiab txiav kev ua tau zoo heev.
quenching: txheej txheem kev kho cua sov uas hloov cov yeeb nkab seamless steel qauv los ntawm austenite mus rau martensite los yog bainite, heats seamless steel yeeb nkab mus rau saum toj AC3 los yog AC1 kub, ces ua kom sov kom txog thaum lub sab hauv ntawm seamless steel yeeb nkab yog kiag li los yog ib nrab austenitized. , thiab tom qab ntawd maj mam txias nws mus rau MS ntawm qhov kub siab tshaj qhov ntsuas kub tseem ceeb los hloov nws mus rau hauv martensite.
Lub hom phiaj ntawm quenching: Lub quenching ntawm seamless steel kav yuav tsum tau ua ke nrog tempering ntawm qhov sib txawv kub kom ua tiav lub hom phiaj ntawm kev txhim kho lub rigidity, hnav tsis kam, hardness, qaug zog thiab toughness ntawm seamless steel kav, yog li ua tau raws li qhov yuav tsum tau rau cov neeg kho tshuab zog. seamless steel kav.
Tempering: Siv ua ke nrog quenching ntawm seamless steel kav, quenched seamless steel yeeb nkab yog rhuab mus rau qhov kub tseem ceeb dua, thiab ces txias hauv huab cua los yog dej los yog roj tom qab ib lub sij hawm ntawm rwb thaiv tsev.
Lub hom phiaj ntawm tempering: Tshem tawm cov kev ntxhov siab sab hauv ntawm seamless steel kav thaum quenching, txhim kho elongation toughness thiab txo hardness thiab zog. Qhov siab dua qhov kub thiab txias, qhov hardness thiab lub zog qis dua, thiab qhov siab dua qhov elongation toughness. Tsis tas li ntawd, tempering ntawm seamless steel kav yuav txhim khu kev ruaj ntseg ntawm cov qauv sab hauv thiab tswj nws cov specifications thiab kev ua tau zoo.
quenching thiab tempering: Kev kho kub kub tempering tom qab quenching ntawm seamless steel kav yog hu ua quenching thiab tempering kev kho mob, uas yog ib tug ob chav cua sov kev kho mob ntawm seamless steel kav mus cuag lub hom phiaj ntawm seamless steel kav uas muaj zoo mechanical zog.
