Pib los ntawm"Khoom siv"
Txhua yam pib nrog cov khoom siv raw; zoo pib ntawm no. Xaiv cov ntaub ntawv tsim nyog yog thawj kauj ruam los xyuas kom meej crawler crane qhov zoo, yog li ua tiav cov txiaj ntsig zoo dua.
Txhawm rau ua tiav lub hom phiaj no, peb cov hlau feem ntau yog los ntawm cov chaw tsim khoom loj xws li Baowu Group thiab HBIS. Rau qee yam khoom tshwj xeeb, peb tuaj yeem los ntawm Tebchaws Europe. Tag nrho cov ntaub ntawv steel tuaj nrog cov ntaub ntawv soj ntsuam zoo, thiab thaum tuaj txog ntawm peb lub tsev rau khoom, cov neeg soj ntsuam zoo tau muab coj mus kuaj thiab tshuaj xyuas 10-20% ntawm cov khoom.
Tsis tas li ntawd, tsis yog txhua tus crawler crane taug qab qhov chaw siv tib cov ntaub ntawv. Peb xaiv cov khoom tsim nyog raws li cov kev cai tshwj xeeb. Xws li, rau Kobelco 7065 crawler crane khiav cov menyuam, 40Mn2 round steel yog qhov tsim nyog tshaj. Kev xaiv rau cov khoom siv kim dua xws li 42CrMn yuav ua rau cov nqi ntau lawm thiab txo tus nqi zoo. Ntawm qhov tod tes, siv cov khoom siv qis dua li 50Mn square steel tuaj yeem ua rau cov menyuam tawg.
Qhov tseem ceeb yog "cov qauv tsim khoom"
Peb tuav ib tug txheej txheem ntau lawm system uas ua kom seamless kev sib koom tes thiab kev hloov nyob rau hauv tag nrho cov ntau lawm theem thiab cov qauv. Qhov kev cog lus no tau lees paub crawler crane undercarriage qhov zoo, txhim kho kev tsim khoom, thiab thaum kawg txhawb kev sib tw ntawm peb cov khoom. "
Piv txwv li, casting txheem ntawm IHI CCH500-2 Crawler Crane Track Shoe:
•Tag nrho cov casting yuav tsum tau Austenitized ntawm 900 degree rau ib Hr rau txhua nti ntawm casting thickness.
•Ces quenched ntawm dej thiab Tempered kom txaus qhov kub thiab lub sij hawm.
•Txhua qhov kev kho cua sov yuav tsum tau ua tom qab castings ncav cuag qhov kub qis dua 200 degree. Lub hardness dav dav tom qab QT yuav yog 280-320 BHN.
•Tag nrho cov qauv kuaj yuav tsum tau muab tso rau hauv HT rauv nrog txhua yam khoom ntawm casting.
Yav dhau los"Quality Standards"
Peb cov khoom lag luam nruj kev soj ntsuam xyuas muaj plaub yam tseem ceeb: kev tshuaj xyuas hauv cov txheej txheem thaum lub sijhawm tsim khoom, kev tshuaj xyuas cov khoom ib nrab, kev tshuaj xyuas tuaj, thiab kev tshuaj xyuas ua ntej xa khoom.
Thaum lub sijhawm tshuaj xyuas, cov qauv random raug sim rau cov tshuaj lom neeg muaj pes tsawg leeg thiab kev ua haujlwm ntawm lub tshuab kom paub meej txog cov teeb meem zoo thiab xyuas kom ua raws li cov lus qhia tshwj xeeb.
Kev tshuaj xyuas cov khoom tiav ib nrab suav nrog kev sim tsis muaj kev puas tsuaj thiab kev txiav txiav. Kev tshuaj xyuas cov khoom tuaj nrog kev tshuaj xyuas 20% ntawm txhua pawg rau qhov tawv tawv, qhov pom, thiab qhov ntev.
Kev tshuaj xyuas zaum kawg ua ntej xa zaub mov npog hardness, tsos, thiab qhov ntev rau 10% ntawm cov khoom.
Cov kev soj ntsuam xyuas zoo no txhawb nqa peb txoj kev cog lus rau kev xa khoom nrog 99.999% kev tsim nyog rau peb cov neeg siv khoom. "
