Iterambere ry'uburyo bwo gutunganya ubushyuhe bw'icyuma cy'umunyururu wo hejuru 23MnNiMoCr54
Gukoresha ubushyuheigena ubwiza n'imikorere y'icyuma gifunganye, bityo uburyo bwo gutunganya ubushyuhe bunoze kandi bunoze ni uburyo bwiza bwo kwemeza ko icyuma gifunganye cyo mu rwego rwo hejuru kidahinduka.
Uburyo bwo kuvura ubushyuhe bw'icyuma cy'umunyururu cya 23MnNiMoCr54 cyo mu rwego rwo hejuru
Uburyo bwo gushyushya hakoreshejwe frequency iciriritse bufite imiterere yo kwihuta gushyushya no kudashyuha cyane, ibyo bikaba bidahuye gusa n'umusaruro w'icyatsi kibisi uriho ubu, ahubwo binagera ku bipimo bimwe na bimwe by'imbaraga n'ubukomere bw'umunyururu w'icyuma gihuza ibyuma. Uburyo bwihariye bwo gukoresha uburyo bwo gushyushya hakoreshejwe frequency iciriritse ni ugukoresha icyuma gishyushya gihuza frequency iciriritse mbere na mbere, kugira ngo hamenyekane uburyo bwo kuzimya no gushyushya iminyururu y'icyuma gihuza ibyuma. Ubushyuhe bwo kuzimya no gushyushya mbere y'uko umunyururu ushyirwa mu muriro bugenzurwa cyane n'ubushyuhe bwa infrared. Binyuze mu igeragezwa, byagaragaye ko uburyo bwo gukonjesha bwo kuzimya no gushyushya ari amazi, Ubushyuhe bw'amazi bugenzurwa munsi ya 30 ℃. Ingufu zo kuzimya zigomba kugenzurwa hagati ya 25-35kw, umuvuduko w'umunyururu ugomba kugenzurwa kuri 8-9hz naho ubushyuhe bugagenzurwa hagati ya 930 ℃ -960 ℃, kugira ngo ubukana bw'urwego rukomeye n'umunyururu bushobore kuzuza ibisabwa bimwe na bimwe by'ubuziranenge. Ingufu zo gushyushya zigenzurwa kuri 10-20kw naho ubushyuhe bugagenzurwa kuri 500 ℃ -550 ℃. Umuvuduko w'umunyururu uguma hagati ya 15 na 16Hz.
(1) Mu ntangiriro zo gukoraumunyururu w'icyuma uhuza uruziga, uburyo bwo gutunganya ubushyuhe ni itanura ritanga urumuri, nk'itanura rizunguruka. Itanura rikoresha convection rikoreshwa mu gushyushya. Ubu buryo bukenera igihe kirekire cyo gushyushya no gukora neza, bimwe muri byo bikaba bikenera umuyoboro muremure wo gukurura. Mu gihe cyose cyo gushyushya umuyoboro, bitewe n'urwego rwo hejuru rw'ubushyuhe bw'ubuso, biragoye kubona ibinyampeke byiza cyane bya austenite, amaherezo biganisha ku bwiza rusange bw'umuyoboro w'icyuma kizengurutse wakozwe icyo gihe. Hamwe n'iterambere rihoraho ry'ikoranabuhanga ryo gutunganya ubushyuhe, uburyo bwo gushyushya hagati bwakozwe mu cyiciro cya nyuma burakoreshwa cyane, kandi ubwiza bwo gutunganya ubushyuhe bw'umuyoboro w'icyuma kizengurutse bwarushijeho kunozwa cyane.
(2) Ikoranabuhanga ryo gushyushya iminyururu, ikoreshwa rya mbere ryo gushyushya ubushyuhe bumwe, imbaraga z'amashanyarazi. Iterambere ry'ihindagurika ry'ubushyuhe ni ugushyushya ubushyuhe buri hagati n'ubushyuhe bumwe hamwe n'ubushyuhe butandukanye. Icyo bita gushyushya ubushyuhe bumwe ni ukuzirikana ko ubukana bwa buri gice cy'umunyururu ari kimwe nyuma yo gushyushya, ariko umunyururu ukorwa no gusudira. Iyo ubushyuhe bwo gushyushya buri hasi cyane, igice cyo gusudira cyoroshye kuvunika, kandi ubukana bw'umunyururu buri hejuru, ubukana buri hagati y'ukuboko gugororotse n'impinduka zo hagati z'icyuma gitwara ibintu nabyo biroroshye cyane gutera imivurungano. Iyo ubushyuhe bwo gushyushya buri hasi, ubukana bw'umunyururu nabwo bushobora kugabanuka. Gushyushya ubushyuhe butandukanye bukoresha ubushyuhe bwo kwihutisha, bukwiriye cyane imiterere yo gushyushya umunyururu, ni ukuvuga ko hejuru y'urutugu rw'umunyururu ifite ubukana bwinshi kandi idapfa kwangirika, kandi ukuboko gugororotse bifite ubukana buke kandi bukomera neza. Ubu buryo bwo kuvura ubushyuhe bushobora kunoza cyane ubwiza bw'umunyururu.
