1 Kev kuaj pom tsis zoo
Ua rau ntawm qhov chaw dye penetrant tshuaj xyuas ntawm qhov chaw ntawm cov menyuam lub cev thiab lub caj dab kom pom seb puas muaj cov kab nrib pleb ntawm qhov chaw; Ua ntsuas ultrasonic nondestructive rau sab hauv ntawm cov menyuam txhawb nqa los xyuas seb puas muaj cov kab nrib pleb, suav nrog, thiab lwm yam tsis xws hauv, nrog rau qhov tob ntawm cov kab nrib pleb, suav nrog, thiab txiav txim siab seb nws puas tuaj yeem kho tau los ntawm kev sib tsoo vuam thiab tus nqi. tig ua rau cov menyuam.
2 Roll nto tig
Raws li tus txheej txheem yuav tsum tau, txiav ib tug hardened txheej tsis muaj tsawg tshaj li 50 hli ntawm ib sab, thiab ua nws mus rau hauv ib tug welding zawj zoo, xyuas kom meej tus tsim thickness ntawm lub surfacing txheej. Ua txhua qhov kev kuaj xyuas qhov tsis zoo ntawm cov txheej txheem txheej txheem thiab vuam zawj kom paub meej tias tsis muaj qhov tsis xws luag ntawm cov menyuam. Yog tias tseem pom muaj qhov tsis xws luag hauv cheeb tsam, txiav qhov tsis xws luag hauv cov kev taw qhia ncig kom txog thaum tsis muaj qhov tsis xws luag.
3 Yob nto preheating
Cov menyuam nkag mus rau lub qhov cub tshwj xeeb rau preheating, nrog rau qhov kub thiab txias ntawm 400 ~ 500 degree; Lub cub tawg kub yuav tsum tau tswj los ntawm lub computer thiab qhov kub thiab txias yuav tsum maj mam nce (30 ~ 40 degree / h); Thaum cov txheej txheem cua sov, cov menyuam txhawb nqa yuav tsum tig maj mam thiab tsis tu ncua kom ntseeg tau tias cov cua sov zoo sib xws. Tom qab cov menyuam ncav cuag qhov kub ntawm qhov kub thiab txias, nws yuav tsum tau khaws cia kom sov rau ib lub sijhawm los xyuas kom meej tias cov tub ntxhais kub kub mus txog qhov yuav tsum tau ua kom sov preheating.
4 Roller nto surfacing
Cov txheej txheej saum npoo tau muab faib ua peb txheej: txheej txheej, txheej txheej hloov, thiab txheej ua haujlwm.
(1) Underlayer: Siv cov hlau tsis tshua muaj carbon alloy vuam hlau nrog kev ua haujlwm vuam zoo thiab lub zog siab. Nws yog tsuas yog siv los ua kom nws muaj kev sib raug zoo nrog lub substrate, tawg tsis kam, thiab siab zog.
(2) Cov txheej txheem hloov pauv: Vim tias qhov nyuaj ntawm lub hauv paus txheej, nws yog ib qho tsim nyog yuav tsum tau ntim 3 txheej ntawm cov txheej txheem hloov pauv nrog hardness thiab lub zog ntawm lub hauv paus txheej thiab txheej txheej ua haujlwm los ua qhov txuas txuas.
(3) Ua haujlwm txheej: Xaiv cov vuam hlau uas muaj cov ntsiab lus carbon tsawg thiab cov ntsiab lus alloy siab los txhim kho lub zog thiab hnav tsis kam ntawm txheej ua haujlwm. Lub hardness ntawm txheej ua hauj lwm yog HSD50-60. Vim yog cov alkalinity siab heev ntawm cov dej txias hauv Anyang Iron thiab Steel Group, cov txheej txheem xaiv ua haujlwm yuav tsum muaj qee qhov kev tiv thaiv alkali.
Tag nrho cov txheej txheem surfacing yog ua nyob rau hauv ib tug preheating rauv, nrog rau cov cua sov preservation thiab surfacing tib lub sij hawm. Lub hom phiaj tsis yog tsuas yog los kho qhov loj ntawm cov menyuam lub cev, tab sis kuj los xyuas kom meej cov khoom siv ntawm cov txheej saum npoo.
5 Roll nto tempering
Thaum lub sij hawm surfacing txheej txheem, ntau tempering kev kho mob yog ua raws li cov txheej txheem tempering yuav tsum tau tshem tawm welding kev nyuaj siab, nthuav hydrogen kev kho mob, txhim kho lub metallographic qauv ntawm surfacing txheej, thiab kho lub hardness ntawm lub surfacing txheej.
6 Roll nto tig
Tom qab txheej txheej saum npoo mus txog qhov loj me, nws yog mounted thiab leveled, thiab yob lub cev loj yog Φ L801mm, nrog rau kev sib tsoo nyiaj ntawm 0.5mm ntawm ib sab.
7 Roller nto tshuaj xyuas
Ua qhov kev sim uas tsis muaj kev puas tsuaj (nto xim, kuaj ultrasonic) ntawm lub cev yob, thiab ntsuas qhov hardness thiab txoj kab uas hla ntawm yob.
Yam ntxwv:
(1) High compressive zog thiab zoo rigidity, txaus los tiv thaiv siab dov rog thiab ncov loads;
(2) Zoo toughness kom tsis txhob muaj menyuam tawg, chim tawg, thiab nto tev;
(3) Cov txheej txheem ua haujlwm ntawm cov menyuam lub cev muaj kev hnav zoo thiab qaug zog ua haujlwm kom txo tau cov menyuam noj;
(4) Cov txheej txheem ua haujlwm ntawm cov menyuam lub cev muaj cov qauv sib xws thiab tawv, ua rau tag nrho cov menyuam nto muaj kev hnav tsis zoo;
(5) Nws muaj kev tiv thaiv corrosion zoo los tiv thaiv corrosion los ntawm qhov kub thiab txias thiab lubricating lossis txias xov xwm thaum kub dov.
