Luluphi uluhlu lwezinto eziphathekayo ezinokuqengqeleka yi-Multi Stand Reducing Rolling Mill

        IMulti Stand Ukunciphisa Rolling Millsisixhobo esiphambili kwimigca yokugqiba imibhobho yentsimbi engenamthungo. Ngokuqhubekayo inciphisa i-diameter yangaphandle yetyhubhu eshushu ehlatyiweyo okanye ekhutshiweyo enomgongxo ngokusebenzisa izitendi zokuqengqeleka ezininzi phantsi koxinzelelo olulawulwayo. Enye inzuzo enkulu yesi sixhobo kukuguquguquka kwayo kwizinto ezahlukeneyo zetsimbi. Ngokuhlengahlengisa iqondo lobushushu eliqengqelekayo, ukuxinezeleka kokuma, uyilo lokupasa kunye nezinto zokuqengqeleka, ilitye lokusila linokwenza uluhlu olubanzi lwamabakala entsimbi kunye nezixhobo zealloyi kwizicelo ezahlukeneyo zemibhobho yoshishino.

Uluhlu lweMathiriyeli yeSimemo esiNinzi sokuNcitshiswa kweMila eqengqelekayo

1. Intsimbi yeCarbon

       Intsimbi yekhabhoni yeyona nto ixhaphakileyo ekusetyenzwa ngayo kwizixhobo zokusila zokunciphisa ii-multi-stand.

       Intsimbi yekhabhoni ephantsi: I-ductility eshushu egqwesileyo, ukusebenza okuzinzileyo okuqengqelekayo. Isetyenziswe ngokubanzi kwimibhobho yokuhambisa amanzi, iibhubhu zensimbi zesakhiwo, imibhobho yomatshini jikelele.

       Intsimbi yekhabhoni ephakathi: Ifuna ulawulo olungqongqo lobushushu ngexesha lokuqengqeleka. Ifakwe kwiindawo zoomatshini, iinxalenye zemibhobho yoxinzelelo.

       Intsimbi yekhabhoni ephezulu: Ukumelana nokuguqulwa okuphezulu. Kufuneka ulawulo loxinzelelo oluchanekileyo kunye nokuthambisa okulungileyo ukunqanda iziphene ezingaphezulu. Ifanelekile kwiityhubhu ezikhethekileyo zoomatshini.

2. Intsimbi ye-Alloy ephantsi

       Intsimbi ephantsi ye-alloy yongeza amanani amancinci ezinto ezixutywayo ukuphucula amandla, ukuqina okuphantsi kobushushu kunye nokumelana nokubola. Amabakala aqhelekileyo aquka uthotho lwe-Cr-Mo, intsimbi ye-Mn-V.

       Ezi zixhobo zisetyenziswa ngokubanzi kwimibhobho yebhoyili, iinqanawa zoxinzelelo, ioli kunye neepayipi zokuthutha igesi. Ngexesha lokuqengqeleka, ilitye lokusila kufuneka lilawule ukufudumeza okufanayo kunye noxinzelelo phakathi kodonga ukuthintela ukungalingani kodonga kunye nokuqhekeka komphezulu.

3. Intsimbi yengxubevange (Medium & High Alloy)

       Intsimbi ephakathi kunye nephezulu ye-alloy ineempawu eziphezulu zokuchasa ukuguqulwa kwe-thermal.

       Izinto eziqhelekileyo: i-chrome alloy steel, i-nickel-chromium alloy steel.

       Ziyamkelwa kwimibhobho yenkonzo yobushushu obuphezulu, iityhubhu zokutshintsha ubushushu kunye nemibhobho yepetrochemical. Iiparamitha eziqengqelekayo kufuneka zilungiswe ngononophelo, kubandakanywa ubushushu bokuqalisa, ukuncitshiswa kokupasa kunye neshedyuli yokupholisa. Uxinzelelo olungafanelekanga luya kubangela lula iziphene zangaphakathi zepolygon kunye nokutenxa eludongeni.

4. Steel engatyiwa

       I-Austenitic stainless steel linqanaba eliqhelekileyo elicutshungulwa ngamashishini okunciphisa amaninzi. Inomsebenzi oqinileyo wokuqina kweempawu kwaye ifuna uyilo olukhethekileyo lokupasa kunye nolawulo lobushushu.

       Isetyenziselwa imibhobho yoshishino lokutya, imibhobho ehambisa ulwelo lweekhemikhali, iityhubhu zokutshintsha ubushushu.

       Qaphela: Insimbi engenasici inokumelana ne-thermal deformation ephezulu. Ukucuthwa ngokugqithisileyo kwendawo enye kunokukhokelela kwimikrwelo, ukukrazuka komphezulu kunye nobukhulu bodonga olungalinganiyo.

5. Ii-alloys eziKhethekileyo (Ulungiselelo oluKhethekileyo luyafuneka)

Ngemiqulu eyenziwe ngokwezifiso, uyilo lokupasa kunye nenkqubo yokufudumala, ilitye lokunciphisa i-multi-stand-standing linokuqengqeleka ezinye iityhubhu ezikhethekileyo zealloy:

       I-alloys ye-Ferritic ekwazi ukumelana nobushushu

       Iityhubhu ze-Titanium alloy (idinga ukulungiswa kwezixhobo ezizinikeleyo kunye nolawulo olungqongqo lwenkqubo)

       Iityhubhu zengxubevange yobhedu (ubushushu obukhethekileyo bokuqengqeleka kunye neqhinga loxinzelelo)

       Isikhumbuzo: I-alloys ezikhethekileyo zidla ngokufuna izinto ezicwangcisiweyo zomqulu, umoya okhuselayo kunye neeparitha zenkqubo, kwaye azifumaneki kwi-standard mill configuration.

Imiba ephambili echaphazela ukuguquguquka kokuqengqeleka kwezinto

       I-Ductility eshushu: Izixhobo ezine-ductility eshushu engalunganga zineefestile ezimxinwa zobushushu eziqengqelekayo, kulula ukuvelisa iintanda.

       Ukuchasana nokuguqulwa: Umxholo ophezulu we-alloy uzisa imfuno ephezulu yokuqengqeleka kwamandla, okubeka iimfuno eziphezulu kwi-stand rigidity kunye nokuqhuba amandla.

       Uvakalelo kuxinzelelo: Ezinye iimathiriyeli zealloyi zinovakalelo lokuguquguquka koxinzelelo. Uxinzelelo olungafanelekanga lubangela ukutenxa kobukhulu bodonga kunye nepolygon yangaphakathi.

       Iimpawu zokupholisa: Izinto ezahlukeneyo zifuna ulawulo lokupholisa olwahlukileyo emva kokuqengqeleka ukuqinisekisa iipropati zoomatshini bokugqibela.

Isishwankathelo

       IMulti Stand Ukunciphisa Rolling Millinokuqengqeleka ipotifoliyo yezinto ezibanzi ukusuka kwintsimbi yekhabhoni eqhelekileyo, intsimbi ephantsi yealloy, intsimbi ephakathi-phezulu ialloy ukuya kwintsimbi yeaustenitic stainless. Kwimibhobho ye-alloy ekhethekileyo efana ne-titanium alloys, i-mill idinga ukulungiswa okujoliswe kuyo kwee-rolls, amandla kunye neenkqubo zokuqengqeleka. Xa ukhetha izixhobo zokuqengqeleka, abasebenzisi kufuneka baqinisekise ibakala lemathiriyeli, ukucaciswa kwemibhobho kunye neemfuno zokusebenza kunye nomenzi wokuhambelana nokucwangciswa komatshini ofanelekileyo kunye nenkqubo yokuqengqeleka.
