General zoo tsom xam ntawm tuab steel phaj rau swivel pob casters

1 Roller mark: Nws yog ib pab pawg ntawm convex thiab concave defects nrog tsis tu ncua thiab pib qhov loj thiab zoo tib yam, thiab cov tsos tsis zoo.

Yog vim li cas:
1) Ntawm ib sab, cov menyuam nto yog concave vim qaug zog los yog tsis txaus hardness ntawm cov menyuam; ntawm qhov tod tes, nws yuav yog tias cov menyuam nto yog stained nrog av, ua ib feem ntawm qhov chaw convex;
2) Thaum lub sij hawm rolling zeb los yog cam khwb cia dov txheej txheem, qhov saum npoo ntawm caster tuab steel phaj yog nias rau hauv lub convex thiab concave defects.

2 Deg impurities: Cov tuam txhab ua haujlwm hnyav hnyav muaj qhov tsis sib xws lossis cov kab tsis zoo ntawm cov hlau tsis huv ntawm cov phaj tuab tuab, thiab lawv cov xim feem ntau yog xim av, xim av, grey lossis dub.

Yog vim li cas:
1) Cov impurities subcutaneous ntawm billet raug nthuav tawm tom qab dov, los yog thawj qhov chaw impurities ntawm lub billet nyob rau saum npoo ntawm caster tuab steel phaj tom qab dov;
2) Cov ntaub ntawv tsis yog xim hlau xws li cov ntaub ntawv refractory thiab av nyob rau hauv lub qhov cub kho cua sov poob rau saum npoo ntawm daim tawv nqaij thiab raug nias rau hauv qhov chaw thaum lub caij txias.

3 Zinc tshauv: Zinc tshauv feem ntau adheres rau saum npoo ntawm tuab steel phaj ntawm caster, npog ib feem los yog tag nrho cov saum npoo, thiab yog grey-dub los yog xim av-liab; qee cov tinplate poob qis, thaum lwm tus yog nias rau hauv qhov chaw thiab tsis yooj yim rau poob; Raws li cov tsos, muaj xws li: liab tinplate, me me ntawm tinplate, strip tinplate, strip tinplate, ntoo-grain tinplate, comet-shaped tinplate, spindle-shaped tinplate, drag-shaped tinplate thiab fibrous tinplate, thiab lwm yam. qhov tob ntawm qhov siab yog qhov tob lossis ntiav.

Yog vim li cas:
1) Kev tsim ntawm nias zinc tshauv yog nyob ntawm cov cua kub ntawm lub billet. Lub sijhawm cua sov ntev dua, qhov kub ntawm cov cua kub ntau dua, qhov muaj zog ntawm cov cua oxidation, qhov ntau zinc tshauv tsim, thiab nws tsis yooj yim rau poob, ua rau qhov nyuaj ntawm kev tshem tawm cov tinplate ib zaug, thiab nws yog nias. mus rau saum npoo ntawm caster tuab steel phaj thaum txias dov;
2) Qhov loj ntsug cov menyuam tsis tau teeb tsa kev tshawb fawb, lub tinplate tsis tau nyem xoob, thiab nws nyuaj rau tshem tawm;
3) Vim tias cov dej tsis tshua muaj siab ntawm cov kav dej siab descaling, cov faucet accessories raug thaiv, cov faucet accessories tsis nyob rau hauv lub kaum sab xis thiab ua haujlwm tsis ncaj ncees lawm, tinplate rau saum npoo ntawm caster tuab steel phaj tsis yog. tshem tawm, thiab nws yog nias rau hauv qhov chaw ntawm lub caster tuab steel phaj tom qab txias dov;
4) Zinc tshauv yog ntau ua nyob rau hauv cov pa roj carbon zoo tib yam, thiab nws yog ib qho yooj yim los tsim cov nplooj ntawv liab thiab dawb hlau nyob rau hauv cov hlau uas muaj cov ntsiab lus silicon siab.

4 Cov thickness tsis sib xws: Lub thickness ntawm txhua feem ntawm lub caster tuab steel phaj yog inconsistent, uas yog hu ua uneven thickness. Txhua lub caster tuab steel phaj nrog cov tuab tsis sib xws yog feem ntau loj heev, thiab cov tuab ntawm qee cov caster stainless hlau tshaj qhov yuav tsum tau ua yuam kev.

Yog vim li cas:
1) Kev hloov kho ntawm qhov sib txawv ntawm qhov yob thiab kev teeb tsa ntawm cov yob hom tsis tsim nyog;
2) Lub piston pins ntawm ob sab ntawm cov hlua kub-kuav los tiag thiab cov hlua kub-kuav los tiag yog puas txawv;
3) Cov cua kub ntawm lub billet tsis sib xws.

5 Cov pob dub: Qhov saum npoo ntawm cov cam khwb cia tuab steel phaj qhia ib feem lossis txuas ntxiv hu ua cov pob dub, uas yog qhov sib txawv thiab qhov tob.
Yog vim li cas yog thaum lub sij hawm cua sov txheej txheem, lub billet yog heev oxidized, thiab lub tinplate yog nias rau hauv qhov chaw thaum lub sij hawm txias dov, thiab me me indentations yog tsim tom qab ntog tawm.

6 Npuas: Muaj irregularly faib annular bulges nyob rau saum npoo ntawm caster tuab steel phaj, qee zaum nyob rau hauv cov duab ntawm loach-zoo li cov kab sib txuas, nrog cov npoo zoo thiab cov roj hauv; Thaum cov npuas tau dov tawm, cov kab nrib pleb tsis zoo tshwm sim; Qee cov npuas tsis bulge, thiab tom qab flattening, qhov saum npoo yog ci, thiab cov hlais hlais yog nyob rau hauv sliced ​​​​txheej txheej.

Yog vim li cas:
1) Muaj ntau cov pa npuas tsis xws luag ntawm lub billet, uas tsis kho tom qab ntau yam txias dov thiab nyob twj ywm rau ntawm lub phaj tuab steel;
2) Lub billet nyob rau hauv lub cub tawg tau ntev thiab cov pa npuas yuav raug.
