Umbhobho wentsimbi ecocekileyo yebakala lococeko

Ibakala lococeko olungenamthungo lwenkqubo yokuvelisa umbhobho wentsimbi yentsimbi - intsimbi ejikelezileyo - ukutyhoboza - umzobo obandayo - ukuqengqeleka okubandayo - ukufakwa kwe-annealing eqaqambileyo - ukupolisha komphezulu wangaphakathi - ukupolisha komphezulu wangaphandle - ukuhlolwa kunye nokwamkelwa - ukugcinwa kokupakisha. 

Imveliso yefektri yombhobho wentsimbi engenamthungo ekumgangatho ococekileyo ukusuka kumzobo obandayo. Kwinkcazo yezixhobo ezininzi eziphambili: 1, umatshini wombhobho wokudweba obandayo: intsimbi ejikelezileyo ene-perforated emva ebizwa ngokuba ngumbhobho, umbhobho jikelele ngu-ф 65 * 5mm okanye i-ф 100 * 7mm. 

Umbhobho jikelele we-sanitary stainless steel stainless ukusuka kwi-ф 14 * 1mm ukuya kwi-ф 200 * 3mm, ngoko ke imfuneko yokwandisa ityhubhu kunye nokutsala ityhubhu encinci, umatshini wokuzoba obandayo ukuze ufezekise. Ngamanye amaxesha ukwandiswa kwetyhubhu ezininzi okanye ii-tubules ziyafuneka, ngelixa i-annealing (unyango lobushushu) kunye nemijikelo yokuchola isenziwa. Iintlobo kunye neenkcukacha zomatshini wetyhubhu womzobo obandayo kunye neentlobo ze-mandrel kunye neenkcukacha azichazwanga. Iinzuzo eziphambili zomzobo obandayo zezi: ukusebenza kakuhle kwemveliso; Kukulungele kwaye kuguquguquka ukutshintsha ukucaciswa kwemveliso ngexesha lemveliso. 

Izixhobo kunye nokuveliswa kwezixhobo kunye nokugcinwa kwesakhiwo sezixhobo zilula. Ukungalungi okuphambili komzobo obandayo kukuba: ukuguqulwa kokupasa kuncinci, ngoko ke ukupasa kokucubungula kuninzi, umjikelezo wemveliso ude; Ukusetyenziswa kwesinyithi kuphezulu. Ukugqitywa kakubi kwiindawo zangaphakathi nangaphandle zetyhubhu. 2. Umatshini wokuqengqeleka ombhobho obandayo oqengqelekayo: sisixhobo esiphambili sokwenza umbhobho wentsimbi ecocekileyo engenamthungo eTshayina. Ububanzi bangaphandle kunye nobukhulu bodonga lwetyhubhu yentsimbi etsalwa ngokubanda ingaphantsi kwe-0.02-0.05mm emva kokuqengqeleka okubandayo.

Ukugqitywa kwendawo yangaphakathi kunye nangaphandle kombhobho nguRa≤0.8μm, kwaye ubukhulu bodonga bungenziwa ukuya kwi-0.5mm. Emva kokupholisa, indawo yangaphakathi nangaphandle yombhobho inokufikelela ku-Ra≤0.2-0.4μm (njengesibuko). Iindidi kunye neenkcukacha multi-roll ebandayo umbhobho rolling yokusila kunye neentlobo mandrel kunye neenkcukacha azichazwanga.

 Ingxaki enkulu yombhobho oqengqelekayo obandayo yimeko enzima, oko kukuthi, amandla e-flexion coefficient inkulu, ayifanelekanga ukwandisa, ukugoba, ukuthetha ngokungqongqo, okanye ayihambelani nemigangatho yesizwe, ngoko kuyimfuneko ukuphumeza. unyango lokuqinisa eshushu (annealing). Ngokubanzi, ityhubhu yensimbi engenasici iphathwa liziko lokunyibilikisa elishushu eliqhelekileyo (iziko lobisi), isikali se-oxide ngaphakathi nangaphandle kombhobho sifuna ukucolwa, nto leyo etshabalalisa umphezulu wangaphakathi nangaphandle wetyhubhu yokuqala eqengqelekayo, kwaye ukubonakala kokungalingani okuncinci, kungekhona kwinqanaba lococeko lombhobho wokugqiba umgangatho wokugqiba. Ke ngoko, ukhuseleko lwerhasi isithando somlilo esikhanyayo kufuneka sikhethwe.

Umgangatho wococeko ongenamthungo wentsimbi yentsimbi engenamthungo incinci iqulethe i-50% yentsimbi kunye ne-10.5% yechromium, kwaye yongeza njenge-nickel, i-titanium, i-molybdenum, njl. onomzimba we-martensite, umzimba we-ferrite, umzimba we-austenitic, isigaba esiphindwe kabini, imvula eyenza lukhuni intsimbi. Iityhubhu zensimbi ezingenasici ezicocekileyo zomgangatho wococeko nazo ziyafumaneka kwizinto ezahlukeneyo. Umzi-mveliso jikelele oqhele ukusetyenziswa ityhubhu ye-austenitic stainless steel material ingaphezulu; 0Cr19Ni9 (USU304), 00Cr19Ni11 (USU 304L), 0Cr17Ni12Mo2 (USU 316), 00Cr17Ni14Mo2 (USU 316L), 1Cr18Ni9Ti (SUS 321), njl njl. kwakunye neemfuno zangaphakathi nangaphandle zokugqiba umphezulu wombhobho wensimbi. Khetha iityhubhu zentsimbi engenamthungo yomgangatho wococeko kunye nohlobo lolwelo oluphakathi, ugxininiso, ubushushu, uxinzelelo, isantya sokuhamba, kunye nezinye izinto.
