Kev sib txuas ntawm cov flanges loj yog ib qho khoom siv uas txuas cov kav dej rau ib leeg, txuas nrog cov yeeb nkab kawg, thiab kaw nrog lub gasket ntawm lawv. Vuam ntawm flanges loj, tseem hu ua vuam flanges, muaj qhov ntawm qhov vuam flange
Tight kev twb kev txuas yog ib hom disc-zoo li tus feem ntau pom nyob rau hauv pipeline engineering.
High forging ceev (150-200mm / s) yog yuav tsum tau rau hlau vuam nrog zoo thermal conductivity ntawm loj flanges. Hais txog tib yam hlau, muaj qhov kub thiab txias gradient nyob rau hauv lub interface cheeb tsam vim qhov txias txias ntawm qhov sib koom ua ke
Yuav tsum tau nce forging ceev. Lub forging siab Fu Fu feem ntau qhia los ntawm lub siab ntawm ib cheeb tsam, uas yog, forging siab zog. Qhov loj ntawm forging siab yuav tsum xyuas kom meej tias cov kua hlau nyob rau hauv lub interface yuav extruded
Muaj qee yam yas deformation.
Vim nws txoj haujlwm zoo inductive, flanges loj yog dav siv hauv tshuaj, kev tsim kho, dej, dej, roj av, lub teeb thiab hnyav industries, tub yees, huv si, kav dej, fais fab, thiab kev lag luam.
Cheng.
Thaum welding loj flanges, yog tias sab saum toj forging siab me dhau, qhov deformation tsis txaus thiab lub zog sib koom ua ke txo; Yog hais tias lub forging sab saum toj siab dhau lawm, qhov deformation yuav loj dhau, thiab cov khoom siv lead ua pob zeb yuav sib tw thiab hnyav, uas yuav txo tau qhov cuam tshuam ntawm kev sib koom tes.
Qhov ceev ntawm lub teeb ci yuav ua rau muaj qhov kub thiab txias, yog li thaum vuam hlau nrog thermal conductivity zoo (tooj liab, aluminium alloys), tshwj xeeb steel flanges yuav tsum muaj qhov loj forging siab (150-400Mpa).
Ntxiv nrog rau cov txheej txheem saum toj no, qhov ntsuas kub ua ntej thiab lub sijhawm preheating yuav tsum tau txiav txim siab rau qhov preheating ci qhov chaw vuam tsis. Lub preheating kub yog xaiv raws li lub workpiece cross-section thiab cov khoom muaj nuj nqi. Thaum welding low-carbon steel,
700-900 degrees.
Feem ntau, phau ntawv arc vuam yog siv rau vuam loj flanges, nrog cov kab tsis zoo arc vuam thiab yooj yim hlawv thiab undercutting ntawm ntug ntug, uas tsis tuaj yeem tshem tawm txawm tias los ntawm machining, ua rau cov tsos tsis zoo; 2. Vim nws feem ntau yog cov hlau sib txawv
Loj vuam tam sim no, tswj tsis zoo ntawm vuam tam sim no, thiab yooj yim tshwm sim ntawm undercutting los yog tsis tiav vuam. Rau loj convex flanges, vuam seam yuav tsum tau ua, kom tsis muaj deposited hlau ntawm lub nplhaib hauv ob sab phlu thiab flange.
