Cored hlau. daim ntawv thov

Vuam hmoov yog ib tug hlau plhaub uas yog ua los ntawm steel sawb thickness ntawm nruab nrab ntawm 0.2 rau 0.5 millimeters. Lub plhaub yog lawm ua tus sau nrog slag thiab roj-txoj kev Cheebtsam.

Vuam flux cored hlau siv nyob rau hauv roj shielded arc rau mechanized los yog qhib arc welding. Cov lus hauj zoo ntawm tus txheej txheem hlau, nws ua ib qho slag thiab roj tiv thaiv los ntawm atmospheric cua. Qhov no yog tshwj xeeb tshaj yog ib qho tseem ceeb thaum ua hauj lwm nyob rau hauv qhib chaw. Täidistraat muab refining thiab alloying ntawm lub weld. Siv nws yog tau tso cai ua ntaub ntawv thov tam sim no muaj ib tug ntom ntawm 150-170 A / mm2. Rau phau ntawv arc vuam uas qhib tam sim no electrodes muaj ib tug ntom ntawm tsis ntau tshaj 20 A / mm2. Täidistraat li tso cai rau tus txheej txheem efficiency thiab ib tug ib nrab rau ob lub sij hawm.

Muaj ntau ntau yam qib ntawm tas mus li electrodes. Piv txwv li, thaum mob khaub thuas vuam cam khwb cia hlau qib khoom siv PP-CH1, kub - PP-H3.

Nws yuav tsum tau muab sau tseg tias txoj kev siv ib tug hlau compound electrode yog ib yam ntawm cov loj txoj kev daws ntau yam teeb meem ntawm kev siv technology tshiab kev kawm. Qhov no tus txheej txheem no siv nyob rau hauv yuav luag tag nrho cov spheres ntawm lub teb chaws kev khwv nyiaj txiag. Cored hlau yog hais tias yuav heev pheej khoom. Nws daim ntawv thov tsis tau tsuas yog pab txoj kev productivity, tab sis kuj zoo ntawm kev ua hauj lwm nqa tawm.

Nws yog siv los nthuav lub ntau yam ntawm fusing steels. Nws daim ntawv thov yog tsim nyog tshwj xeeb tshaj yog nyob rau hauv tus neeg mob qhov twg ib tug monolithic hlau hlau rau ib tug neeg hom ntawm steel tsis tau metallurgically.

Täidistraat categorized los ntawm txoj kev siv los ntawm cov kev tiv thaiv, lub hom phiaj tseem ceeb, cov tub ntxhais ntaus, txhua yam khoom, raws li zoo raws li lub tseem Vuam nyob rau hauv ntau yam txaus qhia.

Feem ntau ntawm cov khoom ua niaj hnub no yog siv rau cov vuam thiab tsawg-carbon tsawg-hlau ntxwv steels. Flux-cored hlau yog manufactured rau tshwj xeeb thiab cov hom phiaj kev. Tus thawj pawg no cov khoom siv nyob rau hauv lub chaw ua hauj lwm nrog yuam weld tsim.

Ntawm kev tseem ceeb yog lub cais ntawm cov khoom thaj chaw ntawm lub leeg thiab cov welding kev twb kev txuas. Qhov no qhia tso cai rau koj los mus txiav txim tus ntsuam ntawm cov khoom ntawm ib tug hom rau rau Vuam ua hauj lwm ntawm lub teeb tsim, yog hais tias tus yam tsawg kawg nkaus uas yuav tsum tau rau tus neeg kho tshuab thaj chaw ntawm cov ntaub ntawv twb txhais rau nws. Cov kev ua raws cai yog nqa tawm los ntawm kev txheeb xyuas cov yam tsawg kawg nkaus yuav tsum tau lub sij hawm ntsuas ntawm kuj mus rhuav, thiab toughness ntawm lub suture hlau. Cov kev ntsuam xyuas yog muab nyob rau hauv lub xeem qauv kuaj. Yuav kom txiav txim seb lub hom ntawm cov hlau ntawm ib tug lav lub sij hawm kuj mus rupture teem tensile zog. Thaum cored hlau faib coj mus qhia cov khoom hom, cov ntaub ntawv uas lub zog thiab pub txoj hauj lwm (spatial) welding.
