Q235D icyuma cya karubone, icyuma gikomeye cyane gikoreshwa cyane mubwubatsi, imodoka, kubaka ubwato, imashini nibikoresho nibindi nganda nyinshi, ariko icyuma gikomeye cyane kigomba gutoranywa neza. Mbere ya byose, amanota ni menshi cyane, bivuze ko igiciro kizaba kinini kubera igiciro kinini cyo gukora. Icya kabiri, urwego rwo hasi rusobanura ko imikorere yumutekano itari kurwego rusanzwe. Icya gatatu, ibisobanuro byibyuma bifite imbaraga nyinshi bigomba gutoranywa bikurikije ibishushanyo mbonera. Icya kane, birasabwa kugura ibikoresho bidasanzwe byubucuruzi kugirango bipime ibyuma bikomeye.

Ifite ubukana bwiza. Mugucunga neza ibigize imiti, kugabanya ibirimo ibintu byangiza muri plaque ya karubone ya Q235D, no guhitamo uburyo bwiza bwo kuvura ubushyuhe, icyuma cya NM360 gifite ubukana bwiza. Kubwibyo, ibice byizewe byubwubatsi birashobora kubakwa ukurikije kunanirwa gukabije kwibice byihanganira kwambara. Q235D icyuma cya karubone ikoresha tekinoroji nibikoresho bigezweho, bifatanije nubuhanga buhanitse kandi bwa siyansi, kuburyo ibikoresho nuburyo bwibicuruzwa ari bimwe kandi byiza.
Icyuma cya S355J2 icyuma cya Q235D icyuma cya karubone icyuma kizunguruka ni inzira igenzurwa. Muburyo bwo kuzunguruka, ubushyuhe bwa ingot ni 1000-1050 ° C; Icyiciro cya mbere gikoresha umuvuduko muke munini wo kugabanya kuzunguruka, icyiciro cy'ubushyuhe bwo hejuru ni 950-1000 ° C, umuvuduko wo kuzunguruka ni 1.6-2.0m / s, igipimo kimwe cyo kugabanya icyuma cya karuboni Q235D ni 15-20%, kandi igipimo cyo kugabanya ni 40-45% kugirango habeho ihinduka ryuzuye rya ingot. Mu cyiciro cya mbere, ubushyuhe bwo gutangira ni 910-930 ° C, naho ubushyuhe bwo kurangiza ni ≤ 870 ° C.
