Cov duab khoom
Khoom Description
E7024 electrode yog hlau- hmoov-titanium coated electrode uas ua raws li cov qauv AWS A5.1. Nws yog tsim los rau lub tiaj thiab kab rov tav fillet vuam thiab tuaj yeem siv rau hauv ob qho tib si AC thiab DC daim ntawv thov. Nws lub ntsiab kom zoo dua yog tias txhua kilogram ntawm electrode tsim 1.5 kilograms ntawm vuam hlau, nce welding productivity los ntawm 50% piv rau cov tsoos electrodes. Nws yog tshwj xeeb tshaj yog haum rau vuam loj - cheeb tsam thiab tuab steel qauv. Cov hlau tso tawm muaj lub zog tensile ntau dua los yog sib npaug ntawm 490 MPa, thiab qhov chaw tawg hauv qhov kev ntsuam xyuas tensile yeej ib txwm nyob hauv lub hauv paus hlau. Lub zog cuam tshuam loj dua lossis sib npaug ntawm 34 J ntawm -20 degree, ua tiav qhov sib npaug ntawm lub zog thiab lub zog, ua tau raws li cov kev cai nruj ntawm cov qauv hnyav xws li txuas hniav thiab cov tsev lag luam.
Core Zoo
1. Kev lag luam-kev ua haujlwm ua haujlwm, 30% siv sijhawm luv dua.
Cov txheej txheej E7024 suav nrog qhov feem pua ntawm cov hmoov hlau, tso nyiaj ntxiv 1.2 kg ntawm cov khoom siv hauv ib teev (siv lub 4.0 hli txoj kab uas hla electrode ua piv txwv). Nyob rau hauv qhov hnyav - lub luag haujlwm choj steel qauv project, lub sijhawm vuam rau 27,500 tons ntawm cov khoom siv tseem ceeb tau luv luv los ntawm 28 hnub piv rau cov phiaj xwm qub, ncaj qha txo cov nqi zog ntau dua 1.2 lab yuan.
2. Cov txheej txheem ruaj khov ua tau zoo, ua rau cov neeg ua haujlwm tshiab tshiab los tsim cov- zoo welds.
Cov yam ntxwv ntawm Arc: Tam sim no qhov hloov pauv ntawm ± 10A nyob ruaj khov, thiab lub pas dej welding tuaj yeem soj ntsuam ntawm - qhov chaw los ntawm kev mloog lub arc lub suab "rustling" (qhov zoo tshaj plaws, lub suab nrov tsis tu ncua zoo ib yam li "frying bacon"). Spatter raug txo los ntawm 40% piv rau E7018, thiab tom qab- lub sijhawm ntxuav vuam yog luv los ntawm 50%.
Slag tshem tawm: Lub slag yog iav, nrog rau qhov tsis siv neeg los ntawm ntau dua lossis sib npaug li 95%. Thawj -thov qhov sib txuas rau qhov kev lag luam loj cog yeeb nkab truss qhov project tau nce ntawm 92% mus rau 98.3%. Cov duab zoo nkauj: Lub vuam nthwv dej yog qhov muag heev thiab qhov seem qhov siab yog tswj ntawm 1-2 hli, thiab cov qauv pom zoo tuaj yeem ua tau raws li qhov tsis muaj kev sib tsoo.

FAQ
Q1: Kuv yuav ua li cas kom tsis txhob hlawv - thaum vuam nyias daim hlau?
A: Siv 3.2mm electrode, tswj qhov tam sim no mus rau 120-140A, siv cov txheej txheem "tawg arc vuam" (nyob rau 0.5 vib nas this ntawm cov ntsiab lus vuam), thiab tuav lub vuam ceev ntawm 15-20cm / min.
Q2: Puas tuaj yeem sib xyaw E7024 thiab E7018?
A: Tsis pom zoo. Qhov sib txawv ntawm cov hlau tso tawm ntawm ob lub electrodes yuav ua rau cov khoom siv vuam tsis sib xws thiab muaj peev xwm 15-20% txo qhov cuam tshuam lub zog.
Q3: Yuav ua li cas yuav tsum damp vuam pas nrig?
A: Qhuav ntawm 150-200℃rau ib teev, ces muab tso rau hauv ib lub thawv insulated ntawm 80-100℃. Yog tias tsis siv hauv 4 teev, rov ua kom qhuav (txog ob zaug).
Q4: Kuv tuaj yeem txo qhov tawg thaum lub sij hawm siab - qhov siab vuam?
A: Txo qhov tam sim no los ntawm 5-10A, welded ntawm lub kaum sab xis "downhill" (10-15 degree), thiab tso lub tais sib nqus hauv qab ua ntej.
Cov txheej txheem kev nyab xeeb
Kev Tiv Thaiv Kev Haus Luam Yeeb thiab Plua Plav: Kev tso pa tawm hauv zos (cov huab cua ntim ntau dua lossis sib npaug li 2000 m³ / h) yuav tsum tau qhib thaum cua ceev ntawm qhov chaw ua haujlwm yog < 2 m / s.
Kev Tiv Thaiv Hluav Taws Xob: Qhov thib ob ntawm lub tshuab vuam yuav tsum tsis txhob muaj -load voltage Tsawg dua lossis sib npaug li 80 V. Siv cov hnab looj tes insulating (voltage resistance Ntau dua lossis sib npaug li 500 V).
