42crmo Umuyoboro udafite ibyuma

Ibisobanuro bigufi:

Ibisobanuro ku musaruro:

Diameter yo hanze y'umuyoboro w'icyuma 20-426

Urukuta rw'icyuma rufite uburebure bwa 20-426

Kumenyekanisha ibicuruzwa:

Intego ya 42crmo idafite umuyoboro wicyuma: ibyuma bidasanzwe byikiraro ni "42crmo", ibyuma bidasanzwe byo gukingira imodoka ni "42CRmo", ibyuma bidasanzwe byubwato ni "42Crmo".Ubu bwoko bwibyuma nugushingira kumahinduka ya karubone (C) kugirango tunoze imiterere yubukanishi bwibyuma, kubwibyo, ukurikije ibirimo bya karubone biri hejuru kandi biri hasi, ubu bwoko bwibyuma bushobora kugabanywamo: ibyuma bya karubone bike - karubone ibirimo muri rusange biri munsi ya 0,25%, nka 10, 20 ibyuma, nibindi.;Icyuma giciriritse giciriritse - ibirimo karubone muri rusange biri hagati ya 0,25 ~ 0,60%, nka 35, 45 ibyuma, nibindi.Ibyuma nkibi ntibisanzwe bikoreshwa mugukora imiyoboro yicyuma.

Ibisobanuro birambuye:

Ibisobanuro bishyushye byo gukora

Ubushyuhe bwo gushyushya 1150 ~ 1200 ° C, gutangira ubushyuhe 1130 ~ 1180 ° C, ubushyuhe bwanyuma> 850 ° C, φ> 50mm, gukonja buhoro.

Guhindura ibisobanuro

Ubusanzwe ubushyuhe 850 ~ 900 ° C, bivuye mu ziko imbeho ikonje.

Ubushyuhe bwo hejuru burambuye

Ubushyuhe bukabije 680 ~ 700 ° C, bivuye mu ziko imbeho ikonje.

Ibisobanuro byo kuzimya no kurakara

Gushyushya ubushyuhe 680 ~ 700 ° C, kuzimya ubushyuhe 840 ~ 880 ° C, gukonjesha amavuta, ubushyuhe bwa 580 ° C, gukonjesha amazi cyangwa gukonjesha amavuta, ubukana ≤217HBW.

Ibisobanuro byo gukomera no gukomera munsi - kuzimya ubushyuhe

Kuzimya ubushyuhe 900 ° C, ubushyuhe 560 ° C, ubukana (37 ± 1) HRC

Ibisobanuro bya induction gukomera no kurakara

Kuzimya ubushyuhe 900 ° C, ubushyuhe bwo hejuru 150 ~ 180 ° C, ubukana 54 ~ 60HRC.
