Lub hom phiaj ntawm cov yeeb nkab steel sizing (txo) yog kom loj (txo) cov yeeb nkab ntxhib nrog txoj kab uas hla loj dua rau cov yeeb nkab steel tiav nrog lub taub me me thiab xyuas kom meej tias cov kab sab nraud thiab phab ntsa tuab ntawm cov yeeb nkab steel thiab lawv qhov sib txawv ntawm cov yeeb nkab steel. ntsig txog kev xav tau.

Qhov tsis zoo los ntawm cov yeeb nkab steel sizing (txo) feem ntau suav nrog geometric dimension sib txawv ntawm cov yeeb nkab steel, sizing (txo) "xiav kab", "nail mark", caws pliav, abrasion, pockmark, puab convexity, puab square, thiab lwm yam.
Geometric dimension sib txawv ntawm cov yeeb nkab steel: Lub geometric dimension sib txawv ntawm cov yeeb nkab steel feem ntau yog hais txog sab nraud, phab ntsa tuab, lossis ovality ntawm cov yeeb nkab steel tom qab sizing (txo) tsis ua raws li qhov yuav tsum tau muaj qhov sib txawv thiab qhov sib txawv ntawm cov qauv tsim.

Tawm ntawm txoj kab uas hla sab nraud thiab ovality ntawm cov yeeb nkab steel: Lub ntsiab yog vim li cas: kev sib dhos tsis raug rau cov menyuam thiab qhov kev hloov ntawm qhov sizing (txo) zeb, tsis tsim nyog deformation faib, tsis zoo ua qhov tseeb, lossis hnyav hnyav ntawm qhov sizing (txo) cov menyuam, siab dhau lossis qis dhau ntawm cov yeeb nkab ntxhib, thiab qhov kub tsis sib xws axial. Nws yog tsuas yog xav tau nyob rau hauv lub qhov zoo thiab cov menyuam sib dhos, txoj kab uas hla txo ntawm cov yeeb nkab ntxhib, thiab cov cua kub ntawm cov yeeb nkab ntxhib.

Out-of-tolerance ntawm steel yeeb nkab phab ntsa thickness: Phab ntsa thickness ntawm cov yeeb nkab ntxhib tsim tom qab sizing (txo) yog tawm ntawm kam rau ua, uas yog mas manifested raws li ib tug tsis sib xws phab ntsa thickness thiab tsis yog-cib puab lub qhov ntawm cov yeeb nkab steel. Nws yog feem ntau cuam tshuam los ntawm cov yam ntxwv xws li cov phab ntsa tuab qhov tseeb ntawm cov yeeb nkab ntxhib, lub qhov zoo thiab qhov hloov kho, qhov nro thaum lub sij hawm sizing (txo) qhov loj ntawm cov yeeb nkab ntxhib txoj kab uas hla txo, thiab cov cua kub ntawm cov yeeb nkab ntxhib.

"Blue kab" thiab "cov cim ntiv tes" ntawm cov kav hlau: "Blue kab" ntawm cov yeeb nkab steel yog tshwm sim los ntawm qhov tsis zoo ntawm cov chais rau hauv ib lossis ob peb lub thav duab ntawm qhov loj me (txo) zeb, uas ua rau lub qhov hom tsis yog " puag ncig", ua rau lub ntug ntawm ib tug tej yam cov menyuam txiav rau saum npoo ntawm cov yeeb nkab steel mus rau ib tug tej yam tob. "Blue kab" khiav mus rau sab nrauv ntawm tag nrho cov yeeb nkab steel hauv daim ntawv ntawm ib lossis ntau kab.

"Cov cim ntiv tes" yog tshwm sim los ntawm qee qhov sib txawv ntawm cov kab nrawm ntawm cov npoo ntawm cov menyuam thiab lwm qhov ntawm qhov zawj, ua rau cov menyuam ntug yuav lo rau cov hlau thiab tom qab ntawd khawb qhov ntawm cov yeeb nkab steel. Qhov teeb meem no tau muab faib raws li qhov ntev ntawm lub raj lub cev, thiab nws cov morphology yog luv luv, zoo ib yam li cov duab ntawm "tus ntiv tes", yog li nws yog hu ua "tus ntiv tes cim". "Blue kab" thiab "cov cim ntiv tes" tuaj yeem ua rau cov yeeb nkab steel raug tshem tawm thaum lawv hnyav.

Txhawm rau tshem tawm "cov kab xiav" thiab "cov cim ntiv tes" qhov tsis xws luag ntawm cov yeeb nkab steel, qhov nyuaj ntawm qhov loj me (txo) cov menyuam yuav tsum tau lav thiab nws cov cua txias yuav tsum tau khaws cia zoo. Thaum tsim lub qhov yob los yog kho lub qhov yob, nws yog ib qho tsim nyog los xyuas kom meej qhov tsim nyog lub qhov sab phab ntsa qhib lub kaum sab xis thiab yob qhov sib txawv los tiv thaiv lub qhov los ntawm qhov tsis zoo.

Tsis tas li ntawd, qhov txo qis ntawm ib qho ntawm ib lub qhov yuav tsum tau tswj kom zoo kom tsis txhob muaj kev nthuav dav ntau dhau ntawm cov yeeb nkab ntxhib hauv lub qhov thaum dov cov yeeb nkab uas tsis kub kub, ua rau cov hlau ntxig rau hauv qhov sib txawv ntawm cov yob, thiab kev puas tsuaj rau cov kabmob vim lub siab dov ntau dhau. Qhov kev xyaum tau pom tias kev siv cov cuab yeej txo qis yog qhov tsim nyog rau kev txwv qhov kev nthuav dav ntawm cov hlau, uas ua tau zoo heev hauv kev txo cov "xiav kab" thiab "cov cim ntiv tes" ntawm cov kav hlau. Cov tsis xws luag muaj qhov zoo heev.

Hlau yeeb nkab caws pliav: Hlau yeeb nkab caws pliav yog muab faib rau hauv daim ntawv tsis sib xws ntawm qhov chaw ntawm lub cev yeeb nkab. Scarring feem ntau yog tshwm sim los ntawm cov hlau nplaum rau saum npoo ntawm qhov loj me (txo) cov menyuam. Nws muaj feem xyuam rau cov yam ntxwv xws li hardness thiab txias txias ntawm cov menyuam, qhov tob ntawm hom qhov, thiab qhov sizing (txo) tus nqi ntawm cov yeeb nkab ntxhib. Kev txhim kho cov khoom siv ntawm cov menyuam, ua rau cov menyuam nto hardness ntawm cov menyuam, ua kom cov menyuam txias txias txias, txo cov yeeb nkab sizing (txo) tus nqi, thiab txo cov txheeb ze zawv zawg ceev ntawm cov menyuam nto thiab cov hlau nto yog qhov tsim nyog rau kev txo qis. lub caij nyoog ntawm cov menyuam lo rau steel. Thaum cov yeeb nkab steel pom tias muaj caws pliav, lub thav duab uas tsim cov caws pliav yuav tsum pom raws li cov duab thiab kev faib tawm ntawm qhov tsis xws luag, thiab cov menyuam qhov chaw uas lo rau cov hlau yuav tsum tau kuaj xyuas, tshem tawm, lossis kho. Cov menyuam uas tsis tuaj yeem raug tshem tawm lossis kho yuav tsum tau hloov raws sijhawm.

Hlau yeeb nkab khawb: Cov yeeb nkab hlau khawb feem ntau yog tshwm sim los ntawm "pob ntseg" nruab nrab ntawm qhov loj me (txo) thav duab thiab qhov chaw ntawm cov yeeb nkab inlet lossis lub qhov hluav taws xob qhia lub raj txuas rau cov hlau, rub thiab ua kom puas ntawm cov yeeb nkab steel txav. . Thaum lub npoo ntawm cov yeeb nkab steel raug khawb, Txheeb xyuas cov ntawv qhia lub raj rau cov hlau nplaum lossis lwm yam txuas rau lub sijhawm, lossis tshem cov hlau "pob ntseg" ntawm qhov sizing (txo) tshuab thav ntawv.

Sab nrauv hemp nto ntawm cov yeeb nkab steel: Lub sab nrauv hemp nto ntawm cov yeeb nkab steel yog tshwm sim los ntawm kev hnav ntawm cov menyuam nto thiab ua ntxhib, los yog qhov kub ntawm cov yeeb nkab ntxhib yog siab dhau, yog li cov nplai oxide nto yog tuab heev, tab sis nws tsis zoo tshem tawm. Ua ntej cov yeeb nkab ntxhib yog qhov loj me me (txo), oxide nplai nyob rau sab nrauv ntawm cov yeeb nkab ntxhib yuav tsum tau muab tshem tawm tam sim ntawd thiab ua haujlwm zoo nrog cov dej kub siab kom txo tau qhov tshwm sim ntawm qhov tsis xws luag ntawm sab nrauv hemp ntawm cov yeeb nkab steel.

Inner convexity ntawm steel yeeb nkab: Lub puab convexity ntawm steel yeeb nkab yog hais txog qhov tseeb hais tias thaum cov yeeb nkab ntxhib yog qhov loj me me (txo), vim yog qhov loj me me (txo) tus nqi ntawm ib tus ncej ntawm sizing (txo) tshuab, cov yeeb nkab. phab ntsa ntawm cov yeeb nkab steel yog khoov rau sab hauv (qee zaum nyob rau hauv ib qho kev kaw), thiab cov kab nrib pleb yog tsim nyob rau sab hauv phab ntsa ntawm cov yeeb nkab steel. Qhov teeb meem no tsis tshwm sim ntau zaus. Nws yog feem ntau tshwm sim los ntawm kev ua yuam kev nyob rau hauv kev sib xyaw ntawm cov menyuam thav ntawv ntawm sizing (txo) tshuab los yog loj yuam kev nyob rau hauv lub qhov zoo hloov kho thaum sizing (txo) nyias-walled steel kav. Los yog lub khib muaj ib qho kev ua tsis tiav. Ua kom qhov nro coefficient tuaj yeem ua rau qhov tseem ceeb ntawm txoj kab uas hla. Nyob rau hauv tib txoj kab uas hla kev txo qis, nws tuaj yeem zam qhov kev tiv thaiv sab hauv ntawm cov yeeb nkab steel. Kev txo qis txoj kab uas hla tuaj yeem txhim kho kev ruaj ntseg ntawm cov yeeb nkab ntxhib thaum lub sij hawm deformation thiab tiv thaiv cov yeeb nkab steel los ntawm convex. Hauv kev tsim khoom, kev sib tw yob yuav tsum tau ua nruj me ntsis raws li lub rooj dov, thiab lub qhov yob hom yuav tsum tau ua tib zoo kho kom tsis txhob muaj qhov tshwm sim ntawm qhov tsis xws luag hauv cov yeeb nkab steel.

"Inner square" ntawm cov yeeb nkab steel: "Inner square" ntawm cov yeeb nkab steel txhais tau hais tias tom qab cov yeeb nkab ntxhib yog qhov loj me me (txo) los ntawm qhov loj me (txo) zeb, lub qhov sab hauv ntawm nws ntu ntu yog "square" (ob-cov menyuam. sizing thiab txo zeb) los yog "hexagonal" (peb-cov menyuam sizing thiab txo zeb). Lub "square square" ntawm cov yeeb nkab steel yuav cuam tshuam rau nws cov phab ntsa thickness raug thiab sab hauv txoj kab uas hla. Qhov "sab hauv square" qhov tsis xws luag ntawm cov yeeb nkab steel muaj feem xyuam rau D / S tus nqi ntawm cov yeeb nkab ntxhib, txoj kab uas hla txo, qhov nro thaum lub sij hawm sizing (txo), lub qhov zoo, dov ceev, thiab dov kub. Thaum D / S tus nqi ntawm cov yeeb nkab ntxhib me me, qhov nro me dua, txoj kab uas hla yuav loj dua, thiab dov ceev thiab dov kub yog siab dua, cov yeeb nkab steel feem ntau yuav muaj qhov tsis sib xws ntawm phab ntsa tuab, thiab " sab hauv square" defect yog pom tseeb dua.
