Q345D Umuyoboro muto wa karubone Umuyoboro wa Carbone Umuyoboro Hagati na Umuvuduko muke wa Boiler Tube

Ibisobanuro bigufi:

Umuyoboro muke muto kandi uringaniye ukoreshwa mubitereko byumuvuduko muke (umuvuduko uri munsi cyangwa uhwanye na 2.5MPa) hamwe nicyuma giciriritse (umuvuduko uri munsi cyangwa uhwanye na 3.9MPa), kandi urashobora gukoreshwa mugukora imiyoboro yubushyuhe bukabije, amazi abira imiyoboro, imiyoboro ikonjesha amazi, imiyoboro yumwotsi hamwe nigitereko cyamatafari yububiko bwamashyanyarazi mato mato, n'ibindi. kuzunguruka.

Umuyoboro muke kandi uringaniye utetse bikozwe muri ingots cyangwa fagitire zikomeye zasobekuwe kugirango zibe umuyoboro wa burr, hanyuma zishyushye zishyushye, ubukonje buzunguruka cyangwa ubukonje bwahamagaye.Umuyoboro w'icyuma udafite icyerekezo gifite umwanya w'ingenzi mu nganda z’icyuma cy’Ubushinwa.Dukurikije imibare ituzuye, Ubushinwa buriho inganda zitunganya imiyoboro idafite imiyoboro igera kuri 240 zirenze, uruganda rukora imiyoboro idafite ibyuma bigera kuri 250, umusaruro w’umwaka utanga toni zirenga miliyoni 4.5.Uhereye kuri kalibiri, <φ76, bingana na 35%, <φ159-650, bingana na 25%.Ku bijyanye nubwoko, toni miliyoni 1.9 za tebes rusange-zigenewe rusange, zingana na 54%;Toni 760.000 z'ibitoro bya peteroli, bingana na 5.7%;Toni 150.000 zinkingi za hydraulic, tebes zuzuye, zingana na 4.3%;imiyoboro idafite umwanda, ifite imiyoboro, imiyoboro yimodoka yose hamwe toni 50.000, bingana na 1.4%.

Umuvuduko muke kandi uringaniye utetse ibyuma bya mashini: imbaraga zingana σb (MPa): ≥ 410 (42) gutanga umusaruro σs (MPa): ≥ 245 (25) kurambura δ5 (%): ≥ 25 kugabanya kugabanuka ψ (%): ≥ 5 .Ishirahamwe ryuma: ferrite + pearlite.

Ikigereranyo giciriritse giciriritse kandi giciriritse: GB3087-1999 icyuma kitagira icyuma kitagira icyuma giciriritse.

Umuyoboro uciriritse kandi wumuvuduko ukabije urashyushye kandi ukonje ukonje (uzungurutswe) utuburungushuye twinshi twicyuma cyiza cya karubone cyubatswe cyifashishwa mugukora imiyoboro yubushyuhe bukabije, imiyoboro y'amazi yazengurutswe hamwe nigituba gishyushye cyane kubitereko bya moteri, imiyoboro minini yumwotsi, imiyoboro ntoya yumwotsi hamwe na arch amatafari yamatafari yuburyo butandukanye bwo gutekesha ingufu ziciriritse.Ahanini ikoreshwa mubyuma byinganda ninganda nzima zo gutwara imiyoboro y'amazi yohasi kandi yoroheje.Ibikoresho byerekana ni ibyuma 10 na 20.
