Cored Hlau Hauv Hlau Fabrication
Cored hlau kuj tseem siv rau hauv cov txheej txheem hlau fabrication, muab ntau yam txiaj ntsig thiab kev ua haujlwm nyob ntawm daim ntawv thov tshwj xeeb.

Kev piav qhia
Cored hlau feem ntau yog siv rau hauv cov txheej txheem vuam, xws li flux-cored arc vuam (FCAW). Hauv FCAW, cov xov hlau cored ua cov khoom muab tub lim uas muaj cov tshuaj flux. Lub flux ua haujlwm rau ntau lub hom phiaj, suav nrog kev tiv thaiv cov vuam los ntawm cov pa paug hauv huab cua, ua kom yooj yim tshem tawm cov impurities, thiab txhim kho cov khoom siv ntawm cov khoom siv vuam. Cored hlau welding muaj qhov zoo xws li kev tso nyiaj ntau dua, nce kev nkag mus, thiab muaj peev xwm vuam hauv ntau txoj haujlwm.
Cored hlau kuj yog siv rau hauv kev siv brazing. Brazing yog cov txheej txheem hlau sib koom ua ke uas siv cov hlau muab tub lim nrog qhov qis qis dua li cov hlau hauv paus tau koom nrog. Cored hlau tuaj yeem ua tiav nrog lub brazing alloy thiab flux, ua kom muaj kev tswj xyuas kev tso tawm ntawm cov hlau muab tub lim thaum txheej txheem brazing. Qhov no ua kom yooj yim rau daim ntawv thov ntawm cov hlau muab tub lim, txhim khu kev ntub dej thiab kev ua haujlwm capillary, thiab txhim kho tag nrho lub zog thiab kev ncaj ncees ntawm kev sib koom tes.
Specification
Thaum lub sij hawm cov txheej txheem ferroalloy ntau lawm, cov hlau cored yog nkag mus rau hauv lub molten hlau da dej. Raws li cov hlau melts, cov khoom tseem ceeb dissolves, tso cov hlau alloying rau hauv cov hlau molten. Qhov no ua rau muaj kev tswj xyuas meej ntawm cov alloy muaj pes tsawg leeg, kom ntseeg tau tias cov txiaj ntsig zoo ib yam thiab rov ua dua tshiab.

Cored hlau yog siv nyob rau hauv thermal txau txheej txheem, xws li arc spraying los yog nplaim hluav taws. Nyob rau hauv thermal spraying, lub tshav kub melts ib co cored hlau, uas yog atomized thiab propelled mus rau ib tug nto los tsim ib tug tiv thaiv los yog haumxeeb txheej. Cov tub ntxhais ntawm cov hlau cored tuaj yeem muaj ntau yam ntaub ntawv, nrog rau cov hlau, alloys, ceramics, los yog cov khoom sib xyaw, nyob ntawm seb cov txheej txheem xav tau. Thermal spraying nrog cored hlau tso cai rau lub deposition ntawm ntom, zoo coatings nrog zoo heev adhesion thiab corrosion kuj.
Cored hlau yog ua hauj lwm rau hlau alloying lub hom phiaj nyob rau hauv fabrication txheej txheem. Cov tub ntxhais ntawm cov hlau muaj cov ntsiab lus alloying uas tau nkag mus rau hauv cov hlau molten los hloov nws cov muaj pes tsawg leeg thiab txhim kho cov khoom tshwj xeeb. Piv txwv li, nyob rau hauv zus tau tej cov hlau, cored hlau uas muaj alloying ntsiab xws li chromium, npib tsib xee, los yog molybdenum yuav siv tau los ua kom tiav cov yam ntxwv yam ntxwv xws li muaj zog, corrosion kuj, los yog kub kuj.
