Ivyuma bishobora guhangana n'ubushuhe 1.4845
Ibihugu vy’Ubumwe bw’Uburayi akenshi bikurikiza ingingo ngenderwako zikomeye z’inganda be n’ibisabwa vyo kurinda ibidukikije mu guhitamwo icuma gishobora guhangana n’ubushuhe. Guhitamwo ibikoresho ntivyitaho gusa ku bijanye n’ubushuhe bwinshi, ariko kandi rifata mu muzirikanyi ubushobozi bwo gutera, ubutunzi n’ukubahiriza amategeko. Ibi bikurikira ni ubwoko bw’ibikoresho rusangi n’ibiranga ibikorwa vyavyo:
1. Ibikoresho nyamukuru n'ingingo mfatirwako z'i Buraya
(1) Ivyuma vy’amabuye y’agaciro (ivyuma vy’amabuye y’agaciro)
Inomero y'ikarata isanzwe:
1.4845 (X15CrNiSi2521, ihuye na US 310S):
Ubushuhe bwo gukingira umubiri burashobora gushika ku 1100 degre , ivyo bikaba bikoreshwa cane mu bidukikije vy’ubushuhe bwinshi.
1.4833 (X12CrNi2313, bihuye na US 309S):
Ubushuhe bwo gukingira umubiri ni nk’amadegre 1000 , kandi igiciro ni gito gatoyi, ivyo bikaba bibereye ku bikoresho vy’ubushuhe hagati n’ubushuhe bwinshi be n’ibikoresho vyo gusukura ubushuhe.
ibiranga:
Ivyuma vyinshi vy’ivyuma vy’ivyuma vy’ivyuma n’ivyuma (Cr 2025%, Ni 1220%) bitanga ubushobozi bwiza cane bwo guhangana n’ugukomera kw’imitsi n’ubushobozi bwo gutera chloride / sulfide, ubushobozi bwiza bwo gusudira, ni bwo guhitamwo cane mu Bumwe bw’Uburayi.
(2) Ivyuma vy’umubiri bitagira ibara ry’umubiri (Imirongo y’Imibumbe y’Ibara)
Inomero y'ikarata isanzwe:
1.4762 (X10CrAlSi25, bihuye na US 446):
Kubera ko ubushuhe bwinshi bw’ivyuma (25% Cr) n’ubushuhe bwo gukingira umubiri bugera ku 900 degre 900 , birabereye ku bidukikije vy’uguhinduka kw’imitsi nk’ivyo gutera amakara.
ibiranga:
Igiciro ni gito, ariko ubushuhe bwinshi n’ubushobozi bwo guhangana n’ubushuhe buragoyagoya kuruta icuma c’umubiri, kikaba gikoreshwa cane cane mu bushuhe buke canke mu bihe vy’ingengo y’imari nke.
(3) Nickel{1}} ishingiye ku nzira (Ibikoresho vy'Ibice)
Inomero y'ikarata isanzwe:
Inkoni 600(2.4816):
Ubushobozi bwo guhangana n’ubushuhe bwa 1200 degre 1200, ugutera carburisation n’uguhungabana kw’ivyuma vy’ivyuma, bikoreshwa mu gikoresho co gutera imiti canke igikoresho co gutera ubushuhe bwinshi cane.
Inkoni 625(2.4856):
Wongeremwo molybdenum naniobium, ushobora guhangana n’ugusenyuka kw’iyon ya chloride, ibereye ibidukikije vyo mu mazi canke ahantu h’ugusenyuka kw’imyanda y’amazi.
ibiranga:
Ibikorwa vyiza cane ariko igiciro kinini, EU irakoreshwa cane cane ku bice nyamukuru canke mu bidukikije vy’ugutegeka.
(4) Ubushuhe {{1}== icuma c'umuriro (Igice c'Igipimo c'Ibarabara)
Inomero y'ikarata isanzwe:
GX40CrSi28(ENJ1029):
chromium nyinshi cane (2530% Cr), ubushobozi bwiza bwo guhangana n’ibintu, bukoreshwa mu gutera ivu ry’aho umuntu yambara cane.
ibiranga:
Igiciro gitoyi n’ugushobora kwambaza, ariko ugucika intege gukomeye, gukeneye kwirinda gutera umuzigo, ibisanzwe mu gukomeza ivyuma vy’ibinyabuzima vyo mu karere.
2. Ibintu bitera ingaruka ku guhitamwo kw'ibikoresho
(1) Amategeko agenga uburinzi bw’ibidukikije aterwa n’
Igiharuro c’Uburaya c’Uburaya (WID 2000 / 76 / EC) gisaba kugenzura imyuka ya dioxin na aside, igipande co guhangana n’ugusenyuka kwa HCl, SO , no guteza imbere ikoreshwa ry’ibikoresho vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma (nk’akarorero
(2) Ingingo ngenderwako z'ubushobozi bw'inguvu
Igikoresho co guhingura ibidukikije (ErP) kiraremesha ubuhinga bwiza bwo gusha, busaba imiterere y’umuyaga (nk’imiterere y’ibintu), n’ibikoresho bifise inkomezi z’ubushuhe bwinshi n’ibiranga uburemere bw’uburemere buke.
(3) Ibisabwa ku butunzi buzunguruka .
The material should be recyclable (such as stainless steel recovery rate>90%), kandi igitigiri c’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma kiragabanuka buhoro buhoro kubera ingorane nyinshi zo gukira.
3. Ivyiyumviro bisanzwe birahuye n'ibikoresho
Ibintu vyerekana
Ikoreshwa cane mu Bumwe bw’Uburaya .
Imisoro ishushe: icuma gishobora guhangana n’ubushuhe 1.4845, icuma c’icuma gishobora gutuma Ubushinwa bukoresha ubushuhe 1.4845, abagurisha, inganda
