Electrodes kev cam khwb cia hlau, lawv cov hom phiaj thiab qhov tseem ceeb ntawm txoj kev siv welding

Nyob hauv txhua ceg ntawm industrial ntau lawm, cam khwb cia hlau ntim ib qhov chaw ntawm cov khoom siv sib txawv. Nws yog siv nyob rau hauv mechanical engineering, lub zog, kev lag luam, kev tiv thaiv kev lag luam, nyob rau hauv lub thauj sector. Electrodes kev cam khwb cia hlau ua rau nws txo tau tus nqi ntawm ntau cov vaj tse thiab txo qhov lawv txoj haujlwm siv. Tsis tshua muaj ntau yam ntawm cov khoom siv nrog cov kev tsim nyog siv mus kom ze rau lawv txoj kev siv ua rau nws muaj peev xwm tsim tau cov pob qij txha ntawm cov khoom sib txuas lus. Ua tsaug rau lawv, qhov uas yuav tsum tau ua tau, qhov nyuaj, qhov ceev, lub zog, kev ua haujlwm, thiab lwm yam kev ua haujlwm ntawm lub cev thiab ua haujlwm raug ua tiav ntawm cov seams.

Electrodes for cast iron yog tsim thiab siv tau los siv tsis tau rau cov hlau no thiab tsim kom muaj zog ruaj ruaj. Feem ntau lawv siv los tshem tawm ntau yam kev ua tsis zoo tsim hauv cov khoom siv los ntawm cov hlau no, rau txoj kev kho kom rov qab los thiab rov kho qhov chaw uas tau hnav lub sij hawm ntev. Electrodes for cast iron kuj zoo kawg nkaus tiv thaiv nrog kev paub tab ntawm vuam hlau, npib tsib xees thiab tooj liab hlau, tooj liab. Qee zaum, nws yuav tsum siv cov khoom ntawm lwm lub hom phiaj tshwj xeeb rau kev tsim cov pob zeb txuas cov pob zeb sib txuas.

Curious yog qhov tseeb hais tias xws li cov khoom uas tsis tsim nyob rau hauv kev lag luam, raws li electrodes rau cam khwb cia hlau, nyob rau hauv Russia tsis muaj standardization ntawm lub teb chaws. Yog li ntawd, lawv feem ntau manufactured raws li kev lag luam thiab lub koomhaum hoom thiab cov kev cai. Nyob rau hauv no hais txog, cim rau hlau electrodes muaj xws li ib tug plurality ntawm ntau hom ntawm vuam khoom. Piv txwv li, cov npe hauv qab no feem ntau yog: ECH-1, ECH-2, ELV-1, AN-1, TSAB-4, thiab lwm yam. Txhua ntawm cov npe no nws muaj nws tus yam ntxwv thiab lub hom phiaj.

Los ntawm txhais tes arc vuam ntawm cam khwb cia hlau electrodes siv rau cov tshem tawm ntawm loj tsis xws luag kho twb kho thiab lub luag hauj lwm uncultivated nto. Nyob rau tom kawg rooj plaub, kub welding yog ua los ntawm txoj kev sib tw da dej ntawm qhov kub ntawm tsis tsawg tshaj li rau puas puas thiab. Qhov no yog qhia zoo ceev thiab weld ntseeg, homogeneity ntawm lub microstructure ntawm lub welded sib koom tes, raws li zoo raws li nws lub zog thiab hardness. Electrodes raws li cam khwb cia nrog diameters mus txog rau kaum millimeters.

Classification rau hlau electrodes ua rau lawv lo lus uas peb (rau gray, zas hlau , lwm yam), cov kev siv technology tshiab nta (rau cov lag luam nyob rau hauv ib tug txawv spatial txoj hauj lwm, rau Vuam da dej), txheej hom (MAG, rutile, los yog ore-qaub-fluorspar ), Cov tshuaj lom neeg muaj pes tsawg tus tub ntxhais kawm thiab txheej txheej (crimping lossis dipping). Ntawm chav kawm, hais tias cov kev faib tawm ntawm cov lej yog nyob ntawm qhov uas cov no lossis lwm hom npe ntawm electrodes.

Cov khoom ntawm ECh-1 hom, uas muab zoo fusion ntawm cam khwb cia hlau nrog ferritic perlite qauv, muab kev nplua vuam thiab cov yeeb yam thiab cov kev zoo ntawm cov seam, lawv tsuas yog siv rau cov vuam tsom yooj yim thiab qhov chaw.
