Ibice byingenzi bigize imiterere yicyuma ni gusudira H-inkingi zicyuma, imirishyo.Guhindura imyenda yo gusudira akenshi ikoresha uburyo butatu bwo gukosora flame: (1) uburyo bwo gushyushya umurongo;(2) Uburyo bwo gushyushya ahantu;(3) Uburyo bwo gushyushya inyabutatu.
1. Kosora ubushyuhe
Ibikurikira nubushyuhe bwo gushyushya mugihe cyo gukosora urumuri (bikozwe mubyuma byoroheje)
Ubushyuhe buke bwo gukosora dogere 500 ~ 600 dogere Uburyo bukonje: amazi
Ubushyuhe bwo hagati bwo gukosora dogere 600 ~ 700 dogere Uburyo bukonje: umwuka namazi
Ubushyuhe bwo hejuru bukosora dogere 700 ~ 800 dogere Uburyo bukonje: umwuka
Icyitonderwa: Ubushyuhe bwo gushyushya ntibukwiye kuba hejuru cyane mugihe gukosora urumuri ari hejuru cyane, kandi hejuru cyane bizatera ibyuma gucika intege bikagira ingaruka ku gukomera.16Mn ntishobora gukonjeshwa namazi mugihe cyo gukosora ubushyuhe bwinshi, harimo ibyuma bifite umubyimba munini cyangwa gukomera.
2. Uburyo bwo gukosora
2.1 Guhindura inguni ya plaque ya flange
Kosora ihindagurika ryibyuma bya H-nkingi, imirishyo ninguni zingoboka.Ku isahani ya flange (hanze ya alignement weld) gushyushya umurongo muremure (ubushyuhe bwo gushyuha bugenzurwa munsi ya dogere 650), witondere urwego rwo gushyushya ntirurenga urwego rugenzurwa nibirenge byombi byo gusudira, ntukoreshe gukonjesha amazi.Iyo ushyushye kumurongo, witondere: (1) ntugomba gushyuha inshuro nyinshi mumwanya umwe;(2) Ntukavomerera mugihe cyo gushyushya.
2.2 Hejuru yo hejuru hamwe no gutandukana hepfo no kugoreka
.Kugira ngo wirinde kugoreka no kugoreka, imikandara ibiri yo gushyushya ikorerwa icyarimwe.Gukosora ubushyuhe buke cyangwa gukosora ubushyuhe buringaniye birashobora gukoreshwa.Ubu buryo burafasha kugabanya imihangayiko muri weld, ariko ubu buryo bufite igabanuka rinini kuruhande rumwe no kugabanuka kurekure, bigoye kubyiga.
(2) Gushyushya umurongo ku isahani ya flange no gushyushya mpandeshatu kurubuga.Koresha ubu buryo kugirango ukosore ihindagurika ryimiterere yinkingi, imirishyo, imirongo, ingaruka ziratangaje, ubugari bwumurongo utambitse wa horizontal muri rusange bifatwa 20-90mm, uburebure bwisahani ni isaha, ubugari bwubushyuhe bugomba kuba bugufi, kandi inzira yo gushyushya igomba kwagurwa kuva hagati yubugari kugera kumpande zombi.Gushyushya umurongo bikorwa neza nabantu babiri icyarimwe, hanyuma ushushe ubugari bwa mpandeshatu ya mpandeshatu ntigomba kurenza inshuro 2 ubunini bwisahani, kandi hepfo ya mpandeshatu ihwanye nubugari bushyushye bwumurongo wibaba rihuye isahani.Inyabutatu yo gushyushya itangirira hejuru hanyuma ikaguka kuva hagati ikagera ku mpande, gushyushya ibice kugeza hasi kugeza munsi ya mpandeshatu.Ubushuhe ntibukwiye kuba hejuru mugihe ushushe urubuga, bitabaye ibyo bizatera depression depression kandi bigoye kuyisana.
Icyitonderwa: Uburyo bwo gushyushya inyabutatu yavuzwe haruguru burakoreshwa no kuruhande rwo kugorora ibice.Iyo hashyushye, hagomba gukoreshwa ubugororangingo bwo hagati, kandi kuvomera bigomba kuba bike.
(3) Umuhengeri wo guhindura inkingi, imirishyo hamwe nurubuga
Kugira ngo dukosore imiterere yimivumba, tugomba mbere na mbere gushakisha impinga yazamutse kandi tugakoresha uburyo bwo gushyushya akadomo hamwe ninyundo y'intoki kugirango dukosore.Diameter ya dot yo gushyushya muri rusange ni 50 ~ 90mm, mugihe ubunini bwicyapa cyicyuma cyangwa agace ka wavy ari nini, diameter nayo igomba kwaguka, ishobora gukanda d = (4δ + 10) mm (d ni diameter yo gushyushya;Grille igenda muri spiral kuva hejuru yumuraba kandi ikosorwa mubushyuhe bwo hagati.Iyo ubushyuhe bugeze kuri dogere 600 kugeza kuri 700, inyundo ishyirwa ku nkombe y’ahantu hashyuha, hanyuma umuhoro ukoreshwa mu gukubita inyundo, ku buryo icyuma cyo muri hoteri gishyuha, kandi kugabanuka gukonjesha.Kugabanuka gukabije bigomba kwirindwa mugihe cyo gukosora.Nyuma yo gukosora akadomo kamwe, ingingo ya kabiri ya crest irashyuha, nkuko byavuzwe haruguru.Kugira ngo umuvuduko ukonje, Q235 ibyuma birashobora gukonjeshwa.Ubu buryo bwo gukosora ni uburyo bwo gushyushya akadomo, kandi gukwirakwiza ingingo zishyushya birashobora kuba bimeze nkibishishwa cyangwa ubwoko bwurunigi.Witondere kurenga dogere 750.
Uburyo bukosora bwo gusudira
Wuzuza gusudira
Igice 5.23 cyasohotse muri AWS D1.1 2015 kivuga ku ngingo zerekeye imyirondoro yemewe kandi itemewe.Iyo ingano ya weld yuzuye ari nini cyane kubera uburangare, ingingo zerekana umwirondoro wo gusudira ziri mu gice cya 5.23 zizasobanuka nabi.Nk’uko Ishyirahamwe ry’imyubakire y’Abanyamerika ryabitangaje, ukeka ko ibyuma birenze urugero byo gusudira bitabangamira ikoreshwa ry’impera y’umunyamuryango, udakosoye icyuma cyuzuza, bishobora gutera impande z’imfuruka zuzuye (haba ku ruhande rumwe cyangwa ku mpande zombi) ) kurenza urugero.Kugerageza gukuraho icyuma kirenze cyasobanuwe hejuru gishobora kuvamo kugabanuka, guhindura no / cyangwa guturika kwa weld.Gukoresha imiterere ya weld weld igomba gukurikiza ibisabwa bijyanye nigice cya 5.23.1 cyigitabo cya AWS D1.1 2015.
Nibihe bintu byemewe byo guterana kugirango habeho inguni?Igice 5.22.1 cyasohotse muri AWS D1.1 2015 kivuga ko kwemererwa gushinga imizi bidashobora kurenga 1.59mm (1/16 muri.) Nta gihindutse.Muri rusange, niba ingano ya weld yiyongera hamwe no kwiyongera kwumwanya wumuzi cyangwa niba byagaragaye ko ibonye inguni isabwa neza, icyuho cyumuzi cyemewe ntikirenza 4.76mm (3/16 muri.).Kubyimbye birenze cyangwa bingana na 76.2mm (3 muri.) Kubisahani yicyuma, agaciro kemewe kumizi ni 7.94mm (5/16 muri.) Mugihe ukoresheje padi ikwiye.
