A, lub kev faib ntawm lub yob yog yuav ua li cas?
Yob yog ua (dov) tsim yas deformation ntawm cov hlau cov cuab yeej, yog ib qho tseem ceeb nyob rau hauv kev txiav txim zoo ntawm efficiency thiab dov zeb noj parts.Roll yog ib tug ntawm cov tseem ceeb nyob rau hauv tus ntxuag zeb dov mills, kev siv ntawm ib khub los yog ib pab pawg neeg ntawm yob dov siab generated los ntawm dov sib tsoo steel.It mas dais lub zog thaum tus ntxuag load, tus ntawm coj thiab kub hloov.
Yob ib tug ntau ntawm ntau phyletic, feem ntau siv steel yob yob cov ntaub ntawv uas faib tawm, cam khwb cia hlau yob thiab yob forging three.The cam khwb cia hlau yob thiab cam khwb cia hlau yob tag nrho mus rau lub casting yob, yog casting molding, tsuas yog tus casting khoom sib txawv.
Lub casting yob: yog hais txog mus rau lub steel smelting los yog melting molten hlau ncaj qha pouring raug hom yob txoj kev ib tug ntau lawm hom.
Forging yob: yog ib tug zoo siab ntawm forging machinery rau hlau dawb paug, ua lawm yas deformation nyob rau hauv thiaj li yuav tau tej yam txhua yam khoom, ib yam zoo thiab loj ntawm yob forging ua txoj kev.
Ob, yob yog siv rau dab tsi tshuab?
Yob raws li qhov sib txawv hardness ntawm yob, qhov teeb meem no yog sib txawv: (1) yob yob hardness txog HRC30-40, yog siv los qhib lub tshuab, loj steel zeb ntawm roughing zeb, thiab lwm yam (2) yob yob hardness txog HRC60- 85, siv rau nyias phaj, medium phaj, medium zoo thiab me me seem steel zeb ntawm lub roughing zeb thiab plaub txhawb cov menyuam ntawm cov menyuam zeb; (3) yob yob hardness txog HRC85-100, siv rau tus mob khaub thuas dov zeb.
Peb, tag nrho cov hom ntawm cov khoom ua technology ntawm yob?
(1) hlau yob ua: smelting, casting, softening kho mob, ntxhib machining, Thaum tshav kub kub kev kho mob (nce hardness), xov, kev soj ntsuam, kev soj ntsuam, khoom tiav.
(2) cov kev ua technology ntawm cov cam khwb cia hlau yob: alloy cam khwb cia hlau yob, piv txwv li: smelting, casting, ntxhib machining, Thaum tshav kub kub kev kho mob, xov, kev kawm ntawv, qhov khuam kom paub tias, thiab lwm yam, khoom tiav.
(3) cov ua cuab yeej ntawm lub forged hlau yob: txias dov ua hauj lwm yob, piv txwv li: lub xaiv ntawm raw cov ntaub ntawv - thaum pib ntawm EBT - LF refining smelting - lub tshuab nqus tsev Degassing rau casting, electroslag remelting rau forging rau spheroidizing annealing, ntxhib machining, tempering, quenching thiab kub tempering rau semi-finishing, qhov khuam kom paub tias mus preheat kev kho mob, muab ob npaug rau-zaus quenching kom txias kev kho mob, uas tsis muaj kub tempering kom tiav machining, hardness, metallographic thiab ntim Hoobkas.
Plaub, cov ua yob feem ntau tshwm teeb meem?
Tam sim no, yob rau dov zeb ua hauj lwm efficiency thiab txo yob noj, nrog siab hardness ntawm yob, nws yog vim hais tias ntawm qhov kev nce rau hauv lub hardness ntawm yob coj nyuaj rau cov zauv yob tshuab factory.Large qhauj txais yuav siab hardness ntawm yob rau CNC machining , tab sis me me kev lag luam tseem siv ntau yob tshuab dhos ua, ua txheej txheem, lub tshuab cov cuab tam co ua txoj siav teeb meem thiab tej teeb meem xws li nto finish yog tsis zoo, muaj kev cuam tshuam cov machining efficiency thiab machining zoo.
