Kev siv ntawmyobfeem ntau tshwm sim los ntawm ntau yam, ua rau muaj ntau yam hnav, tawg, tawg, tawg thiab lwm yam tsis zoo ntawm cov yob, ua rau muaj kev cuam tshuam loj rau peb cov txheej txheem ntau lawm.Txoj kev los daws nws li cas?
Cov hauv qab no piav qhia txog qhov tsis zoo ntawm cov yob thiab kev qhia txog cov kev kho mob.
1.Roller hnav yog muab faib ua peb pawg.
Mechanical hnav yog tshwm sim los ntawm kev sib txhuam ntawm lub ntsej muag yob thiab cov dov qhov chaw.
Thermal hnav yog tshwm sim los ntawm cov nyhuv ntawm kub softening, melting los yog evaporation ntawm txheej txheej.
Corrosion hnav yog tshwm sim los ntawm cov nyhuv tshuaj, cov nyhuv electrochemical, oxidation nyhuv, thiab lwm yam ntawm cov dej noo ntawm cov yob nto, ua rau poob thiab tsiv teb tsaws ntawm cov khoom siv sab nrauv.
2.Roll cracking rolling nyob rau hauv zus tau tej cov heaps ntawm steel, daim card steel, tail chasing thiab lwm yam teeb meem, ua rau ib tug ntse nce nyob rau hauv qhov kub thiab txias ntawm nws ib feem, lub resulting thermal kev nyuaj siab thiab kev tswj kev ntxhov siab tshaj qhov txwv, constituting thermal cracking.
Rolling extension constitutes tus nplaig, nws qhov kub thiab txias yog qis dua qhov nruab nrab ntawm cov dov qhov chaw, yuav ua rau thermal stress li dov kev nyuaj siab sai li sai tau hloov, constituting cuam tshuam cov kab nrib pleb, dov, vim hlau oxide pawg dov, coj tus neeg saib xyuas khawb thiab lwm yam laj thawj yuav. kuj tsim cov kab nrib pleb.
3.Roll tawm qhov muaj pes tsawg leeg thiab nthuav dav ntawm qhov tawg nrawm, ncav cuag qhov ntev thiab qhov tob, yuav ua rau poob.
4. Yob tawg
1) Roll casting shortcomings yob centrifugal casting, vim centrifugal vibration tsim muaj pes tsawg leeg thiab kev npaj ntawm laminar segregation, constituting ceev ceev expansion ntawm tawg, ua rau yob cracking.
2)YobKev kho tsis haum tshuaj lom neeg muaj pes tsawg leeg tsis tsim nyog, qhov tsis zoo ntawm cov cua txias yuav ua rau cov khoom sib cais, carburization lub cev tsis txaus, tsuas yog cov khoom siv dag zog poob, thiab thaum kawg ua rau tawg.
3) Cov txheej txheem txheej txheem yob hauv forging siab yog me me dhau los yog tsis tsim nyog deformation tshwm sim los ntawm cov tub ntxhais ntawm cov yob tsis forged los ntawm, ua rau tawg los ntawm cov siv lead ua.Nws txoj kev kho mob.
1. Covyobyog ua los ntawm hnav-tiv taus thiab kub-tawg resistant khoom, thiab cov kev kho cua sov thiab logistics chemical kev kho mob yog saws los ua homogenize qhov kev npaj thiab ua rau kom cov hnav tsis kam ntawm cov tsos, thiab cov yob raug tshuaj xyuas ua ntej zeb rau hardness thiab ultrasonic tsis. los xyuas kom meej tias tsis muaj kab nrib pleb thiab lwm yam tsis zoo.
2. Thaum tigyob, cov seem oxidation txheej thiab cov kab nrib pleb raug tshem tawm kom txo tau cov kab nrib pleb thiab shedding ntawm yob.3, Tsim nyog kev npaj ntawm yob hloov voj voog, sib tw yob, kos cov ncauj lus kom ntxaws yob txoj kev npaj kho, tswj tus nqi ntawm cov yob kho nyob rau hauv qhov yuav tsum tau teev, tsim nyog qhov chaw ntawm cov dej txias txhaj scale thiab tswj cov dej txias ntim kom paub meej tias qhov txias txias ntawm rolls yog tswj nyob rau hauv ib txwm scale.
4, ntxiv dag zog rau cov khoom taw tes soj ntsuam, tiv thaiv cov khoom siv dov qhov xwm txheej, txo qhov tshwm sim ntawm daim npav hlau, pawg hlau, tus Tsov tus tw chasing thiab lwm yam xwm txheej, kev tswj xyuas nruj ntawm dov kub, tshem tawm cov hlau tsis kub los ntawm lub zeb, kom tsis txhob dov quab yuam overload.
