Ib nrab zaub ntawm cov khoom lag luam

Nrog rau kev tsim kho ntawm science thiab thev naus laus zis, kev siv cov qauv hlau nyob hauv kev tsim kho vaj tse yog qhov ntau thiab ntau dua nyob hauv lub ntiaj teb. Vuam yog qhov tseem ceeb hauv kev siv tshuab hauv cov qauv hlau tsim ua.Vim rau kev txheeb cais ntawm cov teb chaws vam meej, tsuas yog cov hlau siv tom qab vuam siv li ntawm 45% ntawm cov zis steel txhua txhua xyoo.China mus txog thaum kawg xyoo 1980, welded steel qauv tau suav rau 30% ntawm cov zis steel.

Nyob rau xyoo 1992, Tuam Tshoj cov khoom tsim tawm ntawm steel tau 80 lab tons, tab sis txog rau xyoo 1997, Tuam Tshoj cov khoom tso zis steel tau mus txog 94 lab tons. Raws li cov qauv kev txhim kho, Tuam Tshoj cov hlau tsim tawm yuav tawg ua tiav 100 lab tons tom qab nkag mus rau lub xyoo pua tshiab.

Cov yam ntxwv ntawm cov qauv hlau:

Rau cov kub dov steel (Angle steel, i-steel, channel steel, steel tube, thiab lwm yam, sib sau ntawm nyias-phab ntsa steel, steel phaj, txias thiab xaim hlua raws li lub hauv paus pib, los ntawm vuam, ntsia liaj qhov rooj lossis rivet txuas, raws li qee cov cai los txuas rau cov qauv tsev sib txuas, tsis xwm yeem los ntawm kev vuam, ntsia liaj qhov rooj lossis rivet txuas txuas lub tsev txuas yooj yim rau hauv kev teeb tsa raws li cov qauv hlau tiv thaiv lub nra.

Lub zog siab thiab cov huab hwm coj me me.Qhov lub zog ntawm cov hlau yog ntau zaus dua li cov ntoo, cib thiab pob zeb, ua vaj tse thiab lwm yam ntaub ntawv hauv tsev. Yog li no, thaum lub thauj khoom thiab cov xwm txheej zoo ib yam, cov qauv tsim ua los ntawm cov hlau muaj lub cev tuag tsawg dua, cov ntu me me uas yuav tsum muaj, thiab nws yooj yim dua rau kev thauj mus los thiab erection.

(2) Zoo plasticity thiab toughness.Steel muaj plasticity zoo, feem ntau, yuav tsis yog vim muaj kev sib tsoo los yog lub zos dhau los ua rau tshwm sim sai sai, tab sis tshwm sim ua ntej ntawm qhov loj deformation ntawm cov npog, yuav kom coj mus ntsuas .Qhov hlau kuj muaj qhov zoo toughness thiab muaj zog adaptability rau lub zog load ua haujlwm ntawm tus qauv, uas muab kev lees paub zoo rau kev nyab xeeb siv cov qauv steel.

Uniform cov khoom siv.Qhov sab hauv cov qauv ntawm cov hlau tsis sib thooj, cov khoom siv lub cev thiab lub zog ntawm txhua qhov kev qhia yog qhov zoo ib yam, ze rau lub cev isotropic, nyob rau qee qhov kev ntxhov siab, cov hlau nyob hauv lub xeev zoo tagnrho, thiab qhov yooj yim Kev xav tias siv los ntawm kev siv tshuab kev siv tshuab yog qhov sib xws ntau, yog li cov txiaj ntsig kev xam yog qhov raug thiab ntseeg tau.

Yooj yim tsim khoom.Qhov steel qauv yog tsim ntawm ntau cov txheej txheem seem thiab cov phiaj hlau, uas tau ua rau cov khoom siv yooj yim los ntawm kev siv hlau txuas, ntsia liaj qhov rooj lossis txuas rivet, thiab tom qab ntawd thauj mus rau qhov chaw rau kev sib dhos thiab splicing.Yog li ntawd, cov chaw tsim khoom yog yooj yim , daim ntawv thov lub voj voog yog luv, qhov ua tau zoo yog siab, thiab kho, hloov kuj yooj yim.Qhov kev tsim kho ntawm lub Hoobkas tsim thiab qhov chaw nruab muaj qhov zoo ntawm cov khoom loj loj thiab siab qhov tseeb ntawm cov khoom tiav, thiab tau tsim cov haujlwm rau txo tus tus nqi thiab coj mus ua si qhov txiaj ntsig kev lag luam ntawm kev nqis peev.

(5) Kev xeb ua haujlwm tsis zoo.Qhov hlau qauv hlau tsis yooj yim rau xeb hauv huab cua, tshwj xeeb tshaj yog nyob rau hauv cov av noo lossis xeb ua kom xeb ua rau xeb hauv nruab nrab, yog li feem ntau yuav tsum kho thiab kho, xws li xeb, txheej, thiab lwm yam. siab.

Kev ua tsis tau zoo kub tiv thaiv.Ntawm tsis kam tawm nrog qhov kub thiab txias, nrog qhov nce ntawm qhov kub thiab txias, lub zog steel yuav poob qis.Thaum hluav taws kub, cov qauv steel tsis muaj kev tiv thaiv tsuas yog tswj txog li 20min, yog li cov hlau tseem ceeb qauv yuav tsum them sai sai siv tshuaj tiv thaiv kev tua hluav taws, xws li hauv cov qauv hlau sab nraum lub khob cij qhob cij lossis lwm yam khoom siv hluav taws, lossis txau hluav taws kub txheej rau saum npoo ntawm cov khoom sib txuas.

Cov zaub ntawm cov khoom tiav ib nrab ua ntej ua tiav xim raws li tus lej kos duab. Tus naj npawb qhia tau hais tias cov seem tsis pleev xim rau tau xa raws li cov naj npawb, tsis muaj teeb meem kev thauj mus los lossis kev teeb tsa
