Feem ntau tsis xws luag thiab ua rau seem steel
1. Lub kaum sab xis steel tsis puv
Cov yam ntxwv tsis xws luag: Vim yog qhov tsis txaus siab ntawm qhov tiav qhov filling, qhov tsis muaj hlau nyob rau hauv cov ces kaum ntawm cov hlau yog hu ua qhov tsis txaus siab ntawm cov ces kaum ntawm cov hlau, thiab qhov saum npoo yog ntxhib, hauv zos, thiab ntev.
Cov laj thawj yog: (1) cov yam ntxwv ntawm kev hla dhau, cov ces kaum ntawm cov dov qhov chaw tsis tuaj yeem ua tiav; (2) Kev hloov kho zeb ua haujlwm tsis raug, thiab kev faib tawm ntawm qhov txo qis yog qhov tsis tsim nyog. Tus nqi ntawm lub kaum sab xis yog me me, los yog qhov txuas ntxiv ntawm txhua qhov ntawm cov dov daim yog tsis sib xws, ua rau muaj qhov tshwm sim ntau dhau; (3) Daim ntawv hla tebchaws lossis daim ntawv qhia yog hnav hnyav, daim ntawv qhia dav dav lossis kev teeb tsa tsis raug; (4) Tsawg dov kub, tsis zoo hlau plasticity, thiab tsis yooj yim rau sau rau ntawm lub ces kaum ntawm qhov dhau; (5) Cov khoom dov muaj qhov hnyav hauv zos khoov, thiab nws yog ib qho yooj yim los tsim lub kaum sab xis hauv zos tsis txaus siab tom qab dov.
2. Cov duab steel loj yog tawm ntawm whack
Cov yam ntxwv tsis xws luag: Lub sij hawm dav dav rau seem geometry ntawm cov hlau uas tsis ua raws li cov cai ntawm tus qauv. Thaum muaj ntau qhov sib txawv ntawm tus qauv loj, nws yog deformed. Muaj ntau lub npe rau qhov tsis xws luag, feem ntau yog muaj npe tom qab qhov chaw thiab qib ntawm kev sib txawv. Xws li unroundness, ntev, thiab lwm yam.
Ua rau: (1) tsis tsim nyog dhau kev tsim; Kev hnav tsis sib xws ntawm qhov dhau, qhov tsis zoo ntawm qhov qub thiab qhov tshiab; (2) txhua qhov chaw ntawm lub zeb (nrog rau cov cuab yeej qhia ntawv) tau teeb tsa tsis zoo, thiab lub qhov (socket) kev nyab xeeb tau tawg; (3) Kev hloov kho zeb tsis raug; (4) Lub billet kub tsis sib npaug, lub hauv paus kub tsis sib npaug los tsim cov kev qhia tshwj xeeb hauv zos, thiab tag nrho cov hlau tsis kub kub ua rau tag nrho cov ntsiab lus ntev uas tsis sib xws thiab loj dhau.

3. Ntu steel yoj
Cov yam ntxwv tsis xws luag: Vim yog qhov tsis sib xws ntawm kev sib tw ntawm dov, qhov hloov pauv nthwv dej hauv cov seem hauv zos ntawm cov hlau raws li qhov ntev kev taw qhia yog hu ua yoj. Muaj hauv zos thiab muaj dav dav. Qhov ntev nthwv dej ntawm lub duav ntawm I-beam thiab channel steel yog hu ua lub duav yoj; Lub longitudinal undulating nthwv dej ntawm ntug ntawm I-beams, channels thiab Angle ceg yog hu ua ceg nthwv dej. I-beams thiab channel steel nrog lub duav tsis muaj zog muaj qhov sib npaug ntawm qhov ntev ntawm lub duav, thiab qhov tshwm sim ntawm cov hlau sib tshooj thiab tus nplaig kab noj hniav tshwm sim thaum nthwv dej nias ib nthwv dej hauv qhov xwm txheej hnyav.
Ua rau: (1) kev faib tsis zoo ntawm lub siab; (2) yob txoj hlua txav, dov groove tsis ncaj ncees lawm cov hniav; (3) lub hauv ntej lub qhov los yog lub hauv ntej lub qhov dov zawj ntawm cov khoom tiav yog hnav tiag tiag; (4) Tsis sib xws dov kub.
4. Ntu steel txiav
Cov yam ntxwv tsis xws luag: Ntau yam tsis xws luag tshwm sim los ntawm kev txiav tsis zoo yog sib sau ua ke hu ua kev txiav tsis xws luag. Thaum txiav cov hlau me me nrog ya shear nyob rau hauv lub xeev kub, lub caws pliav nrog qhov sib txawv ntawm qhov tob thiab qhov tsis zoo ntawm cov hlau nto yog hu ua kev raug mob; Nyob rau hauv lub xeev kub, qhov saum npoo yog puas los ntawm sawb. Tom qab txiav, txiav nto tsis yog perpendicular mus rau ntsug axis. Qhov kawg ntawm qhov kub dov daim duab yog tsis txiav, thiab lub taub hau txiav yog luv; Tom qab txias shear, cov kab nrib pleb me me hauv zos ntawm qhov shear nto hu ua kua muag. Lub ntsej muag hlau sab laug ntawm lub ntsej muag steel tom qab sawing (txiav) yog hu ua burr.
Ua rau: (1) Lub sawing steel thiab saw hniav (txiav ntug) tsis ntsug lossis lub taub hau ntawm cov dov yog khoov ntau dhau; (2) Cov khoom siv: pom hniav ladle curvature yog loj, pom hniav installation yog tsis tsim nyog, lub sab sauv thiab sab txiav ntug qhov sib txawv loj heev; (3) Nyob rau hauv cov nqe lus ntawm kev khiav hauj lwm: nyob rau tib lub sij hawm, tus naj npawb ntawm cov hauv paus hniav steel yog ntau dhau lawm, qhov kawg yog tsawg dhau, thiab kub dov daim duab yog tsis txiav.
