Mu nganda zizunguruka ibyuma, imizingo ikoreshwa mugukonjesha gukonje n'imirongo ishyushye nibyingenzi byingenzi. Bitewe nuburyo butandukanye hamwe nibidukikije byakoreshejwe byombi, hariho kandi itandukaniro rikomeye muguhitamo ibikoresho bya muzingo. Tuzashakisha muburyo burambuye itandukaniro muguhitamo ibikoresho hagati yimizingo ikoreshwa mumuzingo ukonje n'imirongo ishyushye.
Ubwa mbere, hari itandukaniro rikomeye mubushyuhe bwakazi hagati yumurongo ukonje ukonje hamwe numurongo ushyushye. Imirongo ishyushye ikorwa mubushyuhe bwinshi kandi mubisanzwe ikenera kwihanganira ubushyuhe bugera kuri 1200 ℃. Kubwibyo, ibikoresho byo kuzunguruka kumurongo ushyushye bigomba kuba bifite imikorere yubushyuhe bwo hejuru kandi birwanya umunaniro ukabije. Ibikoresho bisanzwe birimo ibyuma bya chromium bihanitse, ibyuma byihuta, nicyuma cyihanganira ubushyuhe. Ibi bikoresho ntibigumana imbaraga nubukonje gusa mubushyuhe bwo hejuru, ahubwo binarwanya okiside na ruswa ishyushye, bityo bikongerera igihe cyo gukora imizingo.
Ibinyuranye, imirongo ikonje ikonje ikorerwa ku bushyuhe bwicyumba cyangwa hafi yacyo, bityo imizingo ntikeneye kwihanganira ubushyuhe bwinshi. Nyamara, mugihe cyo gukonjesha gukonje, bitewe nibisabwa cyane kurwego rwo hejuru rwicyuma cyurupapuro, ubukana bwubuso hamwe no kwambara birwanya umuzingo ni ngombwa cyane. Imirongo ikonje ikonje ikozwe mubikoresho nkibikoresho byifashishwa, ibyuma bya karubone, cyangwa ibyuma bya chrome. Ibi bikoresho bifite ubukana bwinshi kandi birwanya kwihanganira, bishobora kwemeza ko ubuso bwizingo butambarwa byoroshye mugihe kirekire cyo gukoresha imbaraga nyinshi, bityo bigatuma ubwiza bwibicuruzwa bugera.
Icya kabiri, umutwaro nigitutu cyizingo kumirongo ikonje n'imirongo ishyushye nayo iratandukanye. Umurongo ushyushye ugomba gukenera ibyuma byubushyuhe bwo hejuru mubisobanuro bitandukanye byibyuma, kandi imizingo igomba kwihanganira umuvuduko ningaruka zikomeye, bityo ibikoresho birasabwa kugira imbaraga nyinshi no gukomera. Umurongo uzunguruka ukonje, kubera gukorwa mubushyuhe bwo hasi, cyane cyane ufite ubwoya bwo hejuru hamwe nimbaraga zo guterana hejuru. Kubwibyo, gutoranya ibikoresho byimbeho ikonje byibanda cyane kumyambarire yabo no kurwanya umunaniro.
Byongeye kandi, uburyo bwo kubyara imirongo ikonje ikonje mubisanzwe bikubiyemo uburyo bwinshi bwo kuvura hejuru, nka plaque ya chrome, kuzimya, nibindi, kugirango barusheho kunoza ubuso bwabo no kwambara birwanya. Ariko, kubera gukora mubushyuhe bwubushyuhe bwo hejuru, ubu buryo bwo kuvura hejuru ntibukwiranye numurongo ushyushye. Ahubwo, imikorere yabo yongerewe imbaraga binyuze muburyo bwo kuvanga no gutunganya ubushyuhe bwibikoresho ubwabyo.
In summary, there are significant differences in the material selection of rolls for cold rolling and hot rolling lines, mainly reflected in the different requirements for working temperature, load, pressure, and surface quality. Hot rolling line roll materials need to have excellent high-temperature performance and thermal fatigue resistance, while cold rolling line roll materials emphasize high hardness and high wear resistance. Understanding and correctly selecting suitable roll materials is of great significance for ensuring the stability of the rolling process and product quality. As always, we sincerely appreciate your support and business. Please do not hesitate to contact ssophie@welongchina.com if you have any questions or concerns.
