Isishwankathelo seMveliso - Yintoni imbiza enkulu yeSlag?
A imbiza enkulu yeslag(idla ngokubizwa ngokuba yiiladle yeslag enzima, ibhakede ye-slag enomthamo omkhuluokanyeImbiza yokuguqula i-BOF slag) sisitya esikhulu sesinyithi esenzelwe ukuqokelela, ukuthutha, kunye nokukhupha inkunkuma enyibilikisiweyo kwiifeni zentsimbi ezisebenzisa amandla aphezulu. Ngokungafaniyo neembiza eziqhelekileyo ezisetyenziswa kwiimililo eziphakathi, iimbiza ezinkulu zenkunkuma zisebenzaizityalo zentsimbi ezidityanisiweyoapho abaguquli bezinto ezisetyenziswa ekuguquleni izinto bavelisa iitoni ezingama-200–350 zentsimbi ngobushushu ngabunye, bevelisa ubungakanani obukhulu obulinganayo benkunkuma enobunzima obuphakathi kweetoni ezingama-60 ukuya kwezingaphezulu kwe-100 ngembiza nganye.
Ezi mbiza zisebenza apha1,600°C – 1,700°Ckwaye zinyamezele ukothuka okukhulu kobushushu (ukusuka kwi-slag ebomvu-eshushu ukuya emoyeni ongqongileyo ngexesha lokulahla inkunkuma), impembelelo yoomatshini evela ekuphathweni kwe-crane, kunye nokubola kweekhemikhali okuvela kwizinto ezisisiseko ze-slag. Uyilo lwazo kufuneka lukwamkeleimithwalo enamandlangexesha lokuthambeka kunye nokumelana nokuqhekeka ixesha elide phantsi kwemijikelo enzima ephindaphindwayo.
Iimbiza ezinkulu zeWomic Steel ziveliswa kuphela kusetyenziswaukuphoswa okuhlanganisiweyo kwesiqwenga esinye, ukususa nayiphi na i-weld enokuba yindawo yokuqalisa iintanda. Yonke iyunithi yenzelweUhlalutyo lwezinto ezilinganiselweyo (i-FEA)ukulinganisela amandla, ubunzima, kunye nokumelana nokudinwa bubushushu.

Imibuzo Ebuzwa Rhoqo (FAQ) – Yonke into entsha equlethweyo
Q: Kutheni iimbiza ezinkulu ze-slag kufuneka zenziwe ngomatshini omnye endaweni yokudityaniswa?
A: Imithungo edityanisiweyo kwiimbiza ezinkulu ifumana umahluko omkhulu kuxinzelelo lobushushu (ngaphakathi ukuya kwi-ambient ngaphandle kwe-1,600°C). Ukungalingani kokwandiswa kobushushu kudala imingxunya yokudinwa kwiinzwane ze-weld kwimijikelo embalwa njenge-2,000. I-Integral casting isusa yonke imigca ye-weld, isasaza uxinzelelo ngokulinganayo ngesinyithi esifanayo.
Q: Uyivavanya njani imbiza ye-slag eyi-100 yeetoni ukuze ubone iziphene ezifihlakeleyo?
A: Sidibanisa uvavanyo lwe-ultrasonic oluzenzekelayo (AU) kunye ne-phased array ukuskena i-100% volume, kunye ne-thermography ngexesha lonyango lobushushu, kunye nokuhlolwa kwamasuntswana emagnethi kuzo zonke iindawo. Iindawo ze-trunnion zifumana i-time-of-flight diffraction eyongezelelweyo (TOFD) ukuze kufunyanwe ii-crack.
Q: Singayisebenzisa na imbiza yeslag efanayo kwinkonzo ye-BOF kunye ne-EAF?
A: Akukhuthazwa. I-BOF slag ithambile ngakumbi kodwa inamandla ngakumbi kwiikhemikhali; i-EAF slag ine-viscosity ephezulu kwaye ine-metallics. Siyila ii-engile zodonga lweembiza kunye nee-linings ngokukodwa kwinkqubo enye. Iimbiza zeenjongo ezimbini zihlala zingasebenzi kakuhle.
Q: Lingakanani ixesha eliqhelekileyo lokuhambisa imbiza yeslag enobunzima beetoni ezingama-70?
A: Iiveki ezingama-22–26 emva kokuvunywa komzobo wokugqibela. Oku kuquka ukwenza iipateni (iiveki ezi-4), ukuphoswa kunye nonyango lobushushu (iiveki ezi-6), i-NDT (iiveki ezi-2), kunye nokufakelwa/ukugqunywa (iiveki ezi-2). Iiodolo ezikhawulezayo zinokwenzeka ngepateni esele ikho.
Q: Ndingalindela imijikelo emingaphi ngaphambi kokulungiswa kokuqala?
A: Ngokusekelwe kwidatha yethu evela kwii-38 zeemililo ezidityanisiweyo, imijikelo ephakathi ngaphambi kokuba naluphi na uqhekeko lomphezulu olunokubonwa lukhona.Iibhayisekile ezingama-8,200. Ukugaya okuncinci kunokwandisa ubomi ukuya kwimijikelo eli-12,000. Ukuphinda kuqinisekiswe ngokupheleleyo kuyacetyiswa rhoqo emva kweminyaka eli-10 okanye imijikelo eli-15,000.
Q: Ngaba ungazibonelela iimbiza ze-slag ngokubona ngokuzenzekelayo i-slag okanye ukujonga ubushushu?
A: Ewe. Singadibanisa ii-thermocouples kwi-pot bottom (eneepokotho ezikhuselayo) size sifake i-mounting pad yezinzwa ze-radar slag level. Ii-wire channels ziyafakwa ukuze kuthintelwe iibrakethi zangaphandle.
Q: Yeyiphi i-diameter engaphezulu onokuyibumba?
A: Umatshini wethu wokwakha izinto ulungele ububanzi beembiza ukuya kuthi ga kwiimitha ezi-3.6 (ii-intshi ezili-142). Iimbiza ezinkulu zinokwenziwa ngokusebenzisa i-casting ehlukaniswe ngamacandelo kunye ne-welding, kodwa sicebisa kakhulu i-integral casting ukuze isebenze kakuhle.
Q: Ngaba ninika iwaranti ende kwiimbiza ezinkulu ze-slag?
A: Sinikezela ngewaranti yeenyanga ezili-18 / imijikelo engama-5,000 - nokuba yeyiphi na eza kuqala. Le yimigangatho ephindwe kabini kushishino. Isiqinisekiso esisekelwe ekusebenzeni ngokuzithandela sinokuxoxiswana ngaso kwiiodolo eziphindaphindwayo.
Q: Uqinisekisa njani amandla e-trunnion emva kwemijikelo eliqela?
A: Sicebisa i-UT ephathekayo ehlala kwindawo enye rhoqo kwiinyanga ezili-12. I-Womic inokubonelela ngesixhobo sokuhlola intsimi kunye noqeqesho. Ukuba kufunyenwe ukuguguleka kakhulu, ii-trunnion zinokugqunywa ngentsimbi eweld kwaye ziphinde zenziwe ngokutsha.
Q: Ngaba ungayila imbiza ye-slag ukuze ilingane nee-crane hooks zethu ezikhoyo ngaphandle kokutshintsha i-crane?
A: Ngokuqinisekileyo. Sifuna umzobo weprofayili yehoko yekreyini (kubandakanya ububanzi bokuvula ihoko, ubunzulu bomqala, kunye nomgama wokuvula). Sifanisa ijometri yetruniyoni ngokuchanekileyo nezixhobo zakho zokuphakamisa ezikhoyo.
