Kev xav tau ntawm cov nplaim hluav taws retardant khaub ncaws rau vuam ua haujlwm hauv cov nroj tsuag steel
Nyob rau hauv cov xwm txheej ntawm steel zeb thiab vuam ua haujlwm, nplaim taws retardant khaub ncaws (fr ua hauj lwm khaub ncaws) yog ib qho yuav tsum tau tiv thaiv cov cuab yeej muaj feem xyuam rau lub neej kev nyab xeeb. Cov hauv qab no yog kev txheeb xyuas cov kev xav tau ntawm kev tshaj lij hauv ob txoj haujlwm no:
Foreman: splash of molten steel (above 1600 ℃), heat radiation at furnace mouth (>1000 degree), kev tiv thaiv ntawm molten hlau nkag (EN ISO 11611 tus qauv)
Caster: molten steel splashing thiab pwm overflow thaum lub sij hawm ladle tipping pouring, anti molten hlau nkag (EN ISO 11611 txuj)
Nruam tus neeg teb xov tooj: kub billet txiav txim, cov khoom tawg, tiv thaiv hluav taws kub + kub kub ua haujlwm
Tus neeg teb xov tooj Crane: kev sib tsoo thaum nqa lub ladle (muaj kev pheej hmoo ntawm kev sib tsoo hauv huab cua!), tag nrho lub cev npog kev sib khi tsim (ib qho - daim nplua + lub hau npog)
Kev ua haujlwm tseem ceeb ntawm cov nplaim hluav taws kub retardant khaub ncaws
Khoom siv: Nomex yuav tsum tau siv ® IIIA aramid blend los yog nplaim retardant paj rwb + anti hlau txaws txheej (xws li proban ® Processing)
Daim ntawv pov thawj: ua raws li ob tus qauv ntawm EN ISO 11612 (kev tiv thaiv kub siab) thiab EN ISO 11611 (vuam tiv thaiv)
Tsim: nrog kev cuam tshuam strip (tsis tshua pom kev ib puag ncig), sawv dab tshos + ob npaug - txheej placket (kom tiv thaiv kev nkag ntawm cov hlau molten), tsis muaj lub hnab ntim (kom tsis txhob muaj slag tsub zuj zuj)
⚠️ Zaj lus qhia tuag: Cov khaub ncaws paj rwb zoo tib yam yuav hlawv sai sai thiab ua raws li daim tawv nqaij thaum ntsib cov hlau molten, ua rau kub hnyiab! Cov khaub ncaws nplaim hluav taws kub yog carbonized los tsim cov txheej txheem thermal rwb thaiv tsev rau lub sijhawm khiav.
2, Vuam ua haujlwm: ob qhov kev hem thawj ntawm lub txim thiab arc
Vuam hom thiab qib kev pheej hmoo
Hluav taws xob arc vuam: qhov kub hnyiab tau ncav cuag 2800 degree, thiab qhov tshwm sim ntawm cov khaub ncaws tawg yog siab heev, EN ISO 11611 chav kawm 1;
Gas vuam / txiav: qhib nplaim taws + molten hlau dripping (xws li oxyacetylene txiav), EN ISO 11611 chav kawm 2 (kev tiv thaiv siab dua);
Plasma txiav: ultra siab kub plasma nplaim (16000 degree) sputtering ntau yog dav, chav kawm 2+ hluav taws apron;
Kev tiv thaiv cov ntsiab lus ntxiv
Anti sparking tsim: cov ntaub yuav tsum dhau ISO 9150 anti molten hlau dripping test (dripping aluminium / molten steel tsis nkag mus)
Anti zoo li qub muaj nuj nqi: zam welding sparks detonating plua plav ib puag ncig (xws li steel cog thaj tsam), uas yuav tsum ua raws li en 1149 tus qauv
Cov khoom tseem ceeb:
Lub tsho tawv: npog lub xub pwg / forearm (ua haujlwm rau qhov cuam tshuam ncaj qha)
Balaclava: tiv thaiv lub caj dab thiab pob ntseg (vuam sparks yog ib qho yooj yim rau txaws rau hauv dab tshos)
Contraindications rau kev siv
Nws yog nruj me ntsis txwv tsis pub hnav khaub ncaws zoo tib yam sab nraum cov khaub ncaws (nylon tsho yuav yaj thaum muaj sparks)
Tsis txhob kho los ntawm koj tus kheej: qhov puas tsuaj yuav tsum tau saib xyuas los ntawm tus kws tshaj lij hluav taws xob tiv thaiv khaub ncaws, txwv tsis pub kev tiv thaiv yuav ploj.
Kev tshuaj xyuas ib ntus: Kev ntsuas kev tiv thaiv thermal (TPP Ntau dua lossis sib npaug ntawm 15 cal / cm²) thiab tus nqi tiv thaiv arc (ATPV Ntau dua lossis sib npaug ntawm 8 cal / cm²) yuav tsum ua txhua 6 lub hlis
��️ Qhov kawg tiv thaiv txheej txheem (steel ua + vuam cross scene)
Rau cov hauj lwm raug molten steel txaws + vuam sparks tib lub sij hawm (xws li steel cog khoom tu welder), "sandwich tiv thaiv txoj kev" yuav tsum tau saws:
Hauv qab txheej: nplaim retardant hws absorbing ris tsho hauv qab (Nomex ® Fiber)
Nruab nrab txheej: fireproof thiab thermal rwb thaiv tsev khaub ncaws (txhuas ntawv ci txheej qhia txog radiant tshav kub)
Txheej txheej: Chav kawm 2 vuam nplaim hluav taws kub retardant khaub ncaws (anti spark + molten hlau)
�� Cov ntaub ntawv ceeb toom: raws li kev txheeb cais ntawm US Bureau of Labor Statistics (BLS), qhov kub hnyiab ntawm cov neeg hlau uas tsis hnav khaub ncaws tsim nyog tau nce 3.8 npaug. Hauv cov nroj tsuag steel, cov khaub ncaws uas muaj nplaim taws tuaj yeem txo qhov kub hnyiab tau 50% (tso pov thawj los ntawm NFPA Kev Tshawb Fawb).
