Iindlela zokwenza kunye nokucubungula imibhobho yentsimbi enobubanzi obukhulu

Imibhobho yentsimbi enobubanzi obukhuluzikwabizwa ngokuba yimibhobho yentsimbi enobubanzi obukhulu, ebhekisa kwimibhobho yentsimbi edityanisiweyo eneplating yediphu eshushu okanye iileyiti ze-electro-galvanized kumphezulu wemibhobho yentsimbi enobubanzi obukhulu. I-galvanizing inokunyusa ukuxhatshazwa kwe-corrosion yeepayipi zensimbi kunye nokwandisa ubomi babo benkonzo. Imibhobho yegalvanized isetyenziswa ngokubanzi. Ukongeza ekusetyenzisweni njengemibhobho yoxinzelelo olusezantsi olunje ngamanzi, irhasi, kunye neoyile, ikwasetyenziswa njengemibhobho yeoyile yequla kunye nemibhobho yeoli kushishino lwepetroleum, ngakumbi amasimi eoyile akude nonxweme, nanjengezifudumezi zeoyile kunye nokujiya. kwizixhobo zokupheka iikhemikhali. Imibhobho yezipholileyo, i-distillate yokuhlamba ioyile yamalahle, imibhobho yeemfumba zemibhobho ye-trestle, izakhelo zenkxaso yeetonela zasemigodini, njl.

Indlela yokwenza umbhobho wentsimbi edayamitha enkulu:
1. Indlela yokwandisa i-push push: Isixhobo sokwandisa i-push silula, indleko ephantsi, kulula ukuyigcina, inoqoqosho, kwaye ihlala ixesha elide, kwaye iinkcukacha zemveliso zinokutshintshwa ngokuguquguqukayo. Ukuba ufuna ukulungisa imibhobho yentsimbi enobubanzi obukhulu kunye nezinye iimveliso ezifanayo, kufuneka udibanise kuphela ezinye izixhobo. Ilungele ukuvelisa imibhobho yentsimbi ephakathi kunye nebhityileyo enobubanzi obukhulu, kwaye inokuvelisa imibhobho enodonga olungqingqwa engagqithisi kumthamo wesixhobo.
2. Indlela ye-extrusion eshushu: I-blank idinga umatshini kwaye iqhutywe ngaphambili ngaphambi kokuba i-extrusion. Xa i-extruding fittings yepayipi kunye nobubanzi obungaphantsi kwe-100mm, utyalo-mali lwezixhobo luncinci, inkunkuma yezinto eziphathekayo incinci, kwaye iteknoloji ikhulile. Nangona kunjalo, xa ububanzi bombhobho bukhula, indlela yokutshisa i-extrusion idinga i-tonnage enkulu kunye nezixhobo eziphezulu zamandla, kunye nenkqubo yokulawula ehambelana nayo kufuneka iphuculwe.
3. Indlela eshushu yokugqobhoza: Ukugqobhoza okushushu kusekelwe ikakhulu kulwandiso lokuqengqeleka olude kunye nolwandiso lokuqengqeleka. Ukuqengqeleka okude kunye nokuqengqeleka kolwandiso ikakhulu kubandakanya ukuqengqeleka kwetyhubhu eqhubekayo kunye ne-mandrel eshukumayo engapheliyo, ukuqengqeleka kwetyhubhu engapheliyo kunye ne-mandrel emincinci, ukuqengqeleka kwetyhubhu emithathu eqhubekayo kunye ne-mandrel encinci, kunye ne-tube ejikelezayo ejikelezayo kunye ne-mandrel edadayo. Ezi ndlela zinemveliso ephezulu, ukusetyenziswa kwentsimbi ephantsi, iimveliso ezilungileyo, kunye neenkqubo zokulawula, kwaye zisetyenziswa ngokubanzi.

Okwangoku, iinkqubo eziphambili zokuvelisa kwimibhobho yentsimbi enobubanzi obukhulu kwilizwe lam yimibhobho yentsimbi enobubanzi obushushu obushushu kunye nemibhobho yentsimbi eyandisiweyo yobushushu. Iimpawu ezinkulu zemibhobho yensimbi engenamthungo eyandisiweyo yi-325 mm-1220 mm kunye nobukhulu be-120mm. Imibhobho yentsimbi engenamthungo eyandisiweyo ene-thermal inokuvelisa imilinganiselo engeyiyo eyelizwe. Umbhobho ongenamthungo yinto esihlala siyibiza ngokunyuka kwe-thermal. Yinkqubo yokugqiba imibhobho erhabaxa apho imibhobho yentsimbi enoxinano oluphantsi kodwa ukucutheka okuqinileyo kwandiswa ngokunqamleza okanye ukuzoba iindlela. Imibhobho yentsimbi etyebileyo ngexesha elifutshane inokuvelisa iintlobo ezingezizo nezikhethekileyo zemibhobho engenamthungo enexabiso eliphantsi kunye nokusebenza kakuhle kwemveliso. Le yindlela yophuhliso lwangoku kwintsimi yokuqengqeleka kwemibhobho.

Imibhobho yentsimbi edayamitha emikhulu iyatsalwa kwaye inyangwe ngobushushu phambi kokuba iphume kumzi-mveliso. Le meko yonikezelo ibizwa ngokuba yi-annealed state. Injongo ye-annealing ikakhulu ukuphelisa iziphene zesakhiwo kunye noxinzelelo lwangaphakathi olushiywe kwinkqubo yangaphambili kunye nokulungiselela ulwakhiwo kunye nokusebenza kwenkqubo elandelayo, njengentsimbi ye-alloy structural, insimbi yesakhiwo kunye nokuqina okuqinisekisiweyo, isinyithi esinesihloko esibandayo, kunye nokuthwala. intsimbi. Iintsimbi ezifana nentsimbi yesixhobo, intsimbi ye-steam turbine blade, kunye ne-cable-type-stainless heat-resistant steel zidla ngokusiwa kwindawo evalelweyo.

Indlela yokusetyenzwa kombhobho wentsimbi edayamitha enkulu:
1. Ukuqengqeleka; indlela yokucutshungulwa koxinzelelo apho izikhala zentsimbi zombhobho wentsimbi ezinobubanzi obukhulu zigqithiswa kwisithuba (seemilo ezahlukahlukeneyo) phakathi kweerola ezijikelezayo. Ngenxa yokunyanzeliswa kwee-rollers, i-cross-section of material iyancitshiswa kwaye ubude bunyuswa. Le yindlela eqhelekileyo esetyenziswayo yokuvelisa imibhobho yentsimbi enobubanzi obukhulu. Indlela yokuvelisa isetyenziswa ikakhulu ukuvelisa iiprofayili zemibhobho yentsimbi enobubanzi obukhulu, iipleyiti, kunye nemibhobho. Ukwahlula-hlulwa kukuqengqeleka okubandayo kunye nokuqengqeleka okushushu.
2. Ukubumba; indlela yokucutshungulwa koxinzelelo esebenzisa impembelelo ebuyiselayo yesando sokubumba okanye uxinzelelo lokushicilela ukutshintsha into engenanto ibe yimo kunye nobukhulu esiyifunayo. Ngokuqhelekileyo zahlulwe zibe yi-forging yamahhala kunye ne-dieforging, zihlala zisetyenziselwa ukuvelisa izinto ezinkulu, izikhala, kunye nezinye izinto ezinamacandelwana amakhulu kunye needamitha ezinkulu.
3. Umzobo: Yindlela yokucubungula eyenza intsimbi edibeneyo (emilo, ityhubhu, imveliso, njl.) ngokusebenzisa umngxuma wokufa kwi-cross-section encitshisiweyo kunye nobude obuninzi. Uninzi lwazo lusetyenziselwa ukusebenza okubandayo.
4. Extrusion; yindlela yokucubungula apho imibhobho yensimbi enobubanzi obukhulu ibeka isinyithi kwi-cylinder evaliweyo ye-extrusion kwaye ifake uxinzelelo kwelinye icala ukuze ikhuphe isinyithi ukusuka kumngxuma wokufa omiselweyo ukufumana iimveliso ezigqityiweyo zemilo kunye nobukhulu obufanayo. Isetyenziswa kakhulu kwimveliso. Umbhobho wentsimbi ongeyoron-ububanzi obukhulu.
