Yintoni iHot Rolled Seamless Pipe?

Iipayipi zibalulekile kumashishini afana neoyile negesi, ulwakhiwo, iimoto, kunye nokuveliswa koomatshini. Phakathi kweentlobo ezahlukeneyo,umbhobho oshushu oqengqekileyo ongenamthungoIbalasele ngamandla ayo, ukufana kwayo, kunye nokukwazi kwayo ukumelana noxinzelelo oluphezulu kunye nobushushu. Ngokungafaniyo nemibhobho edibeneyo, imibhobho engenamthungo ayinamthungo we-weld, nto leyo eyenza ukuba ilungele ukusetyenziswa okubalulekileyo. Kweli nqaku, siza kuhlola ukuba yintoni umbhobho ongenamthungo ogoqwe ngobushushu, indlela owenziwe ngayo, iingenelo zayo, kunye nokusetyenziswa kwayo okuqhelekileyo kumashishini.

1. Inkcazo: Yintoni iHot Rolled Seamless Pipe?

A umbhobho oshushu oqengqekileyo ongenamthungoluhlobo lombhobho wentsimbi owenziweyongaphandle kokuweldakwaye yenziwe ngeinkqubo yokuqengqeleka eshushuIgama elithi “umthungo” libonisa ukuba umbhobho awunalo naluphi na udibaniso okanye umthungo kubude bawo, nto leyo eyomeleza ukuqina kwawo kunye nokuthembeka kwawo.

Ukuqengqeleka okushushu kubhekisa ekwenzeni umbhobhoamaqondo obushushu aphezulu, idla ngokuba ngaphezulu kwe-1000°C, nto leyo evumela ukuba intsimbi ibunjwe kwaye icutshungulwe lula. Le ndlela iphumela kumbhobho oqinileyo, ofanayo ofanelekileyo kwiintlobo ngeentlobo zezicelo ezifuna amandla.

2. Yenziwa njani iHot Rolled Seamless Pipe?

Ukwenziwa kombhobho oshushu ogoqwe ngomthungo kubandakanya amanyathelo aliqela abalulekileyo:

a) Ukulungiswa kweBillet

• Ibhilethi yentsimbi eqinileyo esisilinda iyanqunyulwa ibe nobude obufunekayo.

• I-billet itshiswa kwisithando somlilo ukuya kubushushu obuphezulu ukuze ithambile.

b) Ukubhoboza

• I-billet eshushu idlula kwi-mill ebhobozayo ukuze yenze iziko elingenanto.

• Isibhobozi esijikelezayo kunye neerola zisetyenziselwa ukwenza imilo esisiseko yetyhubhu.

c) Ukwandiswa

• I-billet ebhoboziweyo (ngoku eyityhubhu engenanto) idlula kwii-elongation mills ezifana nee-mandrel mills okanye ii-plug mills.

• Ezi matshini zolula umbhobho kwaye ziphucula ubukhulu nobubanzi bodonga.

d) Ukuqengqeleka Okushushu

• Le tube ibunjwe kwaye ilinganiswe ngakumbi ngokusebenzisa ii-hot rolling mills.

• Oku kuqinisekisa ukufana kunye nokuchaneka kobukhulu.

e) Ukupholisa kunye nokuLungelelanisa

• Umbhobho upholiswa kwi-conveyor okanye emoyeni.

• Emva koko iyalungiswa ize inqunyulwe ibe bubude obufunekayo.

f) Ukuhlolwa noVavanyo

• Imibhobho idlula kwiimvavanyo ezahlukeneyo ezingonakalisiyo nezingonakalisiyo (umz., i-ultrasound, i-hydrostatic).

• Ukumakishwa kunye nokupakishwa kwenziwa ngokwemigangatho yoshishino.

i-sakysteelIbonelela ngeepayipi ezigoqekileyo ezishushu ezingashukumiyo kwiindidi ezahlukeneyo kunye nobukhulu, ivavanyiwe ngokupheleleyo kwaye iqinisekisiwe ukuqinisekisa umgangatho.

3. Iimpawu eziphambili zePipe engenamthungo eHot Rolled

• Ulwakhiwo olungenamthungo: Akukho mthungo odibeneyo uthetha ukumelana noxinzelelo olungcono kunye nokuqina kwesakhiwo.

• Ukumelana nobushushu obuphezulu: Iyakwazi ukumelana nobushushu obuphezulu ngaphandle kokuguquka okanye ukusilela.

• Ukunyamezela uxinzelelo: Ukusebenza kakuhle kakhulu phantsi koxinzelelo oluphezulu lwangaphakathi okanye lwangaphandle.

• Ubukhulu Bodonga Olufanayo: Ukuqengqeleka okushushu kuqinisekisa ulawulo olungcono lokutyeba.

• Ukugqitywa Okuhle KomphezuluNangona ingekho bushelelezi njengemibhobho etsalwa kubanda, imibhobho egoqwe ngobushushu inesiphelo esamkelekileyo sokusetyenziswa kwimizi-mveliso.

4. Izixhobo kunye neMigangatho

Iipayipi ezigoqwe ngobushushu ezingenamthungo ziyafumaneka ngezixhobo ezahlukeneyo kuxhomekeke kwisicelo:
