Isishwankathelo seMveliso – Kutheni iimbiza zeSlag eziphakathi zingumqolo weeMill ezininzi zeNsimbi

Iimbiza ze-slag eziphakathi(iitoni ezingama-20–50) zezona zitya zixhaphakileyo zokuphatha inkunkuma kwiindawo ezincinci ukuya kweziphakathi zokusika intsimbi, kwizityalo zentsimbi ezikhethekileyo, nakwiindawo zokusekwa. Zisebenza ngeentlobo ezahlukeneyo zeziko:

●I-EAF yeetoni ezingama-50–100(ukwenziwa kwentsimbi okuxhaphakileyo okusekwe kwiinkunkuma)

●Iifenishi ze-LF ladleyokucoca okwesibini

●Ii-converter ze-BOF ukuya kuthi ga kwiitoni ezili-120(ukwahlulwa kwe-slag)

●Izinyibilikisi ezingezizo iintsimbi(ubhedu, i-nickel, i-lead)

●Iindawo ezinkulu zokusekwakunye nee-induction furnitures ezingama-30–60 ton

Ngokungafaniyo neembiza ezincinci (5–15t) ezisetyenziswa rhoqo kwimisebenzi yeqela, okanye iimbiza ezinkulu (60–100t) kwiifektri ezinkulu ezidityanisiweyo, iimbiza eziphakathi zisebenza kwiukukhwela ibhayisekile okuphakathi kodwa okunamandla– ngesiqhelo ii-heat ezili-10–15 ngosuku, iintsuku ezi-5–6 ngeveki. Zifuna ibhalansiumthamo, ukuqina, kunye nexabiso.

Indlela eyintloko yokusilela kwiimbiza eziphakathi ayikokudinwa kobushushu (njengakwiimbiza ze-EAF) okanye ukukrala (njengakwiimbiza ze-BOF) - yiyoimpembelelo yoomatshini + ukothuka kobushushu kudityanisiweIimbiza eziphakathi zihlala zithuthwa phezu komgangatho orhabaxa, zithambeke ngeekhreyini ezingacwangciswanga kakuhle, kwaye ngamanye amaxesha zigcinwa ngaphandle, nto leyo ekhokelela ekupholeni okungalinganiyo.

I-Womic Steel iphucule uyilo lwethu lwembiza ye-slag ephakathi ukuze ijongane nale mingeni ithile:

●Ukumelana nempembelelo okwandisiweyo- umqolo otyebileyo kunye nokuqinisa ezantsi

●Ukunciphisa uxinzelelo loxinzelelo– ii-radii ezinkulu ze-fillet kuzo zonke iinguqu

●Isibonelelo sokugqwala kwendawo yokugcina izinto ngaphandle– ubukhulu bodonga obungaphezulu kwe-3mm kwiindawo zangaphandle

Imibuzo Ebuzwa Rhoqo (FAQ) – Iimbiza Eziphakathi Ze-Slag

Q: Yintoni umahluko phakathi kwembiza yeslag “ephakathi” kunye nembiza “enkulu”?
A: Ayingobukhulu nje kuphela. Iimbiza eziphakathi zenzelwe ukusetyenziswa rhoqo ngexesha lokujikeleza (10–15/ngosuku) kunye nokusetyenziswa ngokubanzi. Iimbiza ezinkulu (60+ t) zakhelwe iimatshini ezidityanisiweyo ezinemijikelo ecothayo kodwa zinokumelana okuphezulu kokurhubuluza. Sinemithetho eyahlukileyo yoyilo kudidi ngalunye.

Q: Ndingayisebenzisa imbiza yeslag ephakathi kwi-BOF slag?
A: Ewe, kwii-converter ze-BOF ukuya kuthi ga kwiitoni ezili-120. Nangona kunjalo, i-BOF slag ayinamatheli kakhulu kodwa inamandla ngakumbi kwiikhemikhali. Sicebisa i-ZG310-570 okanye i-GS-20Mn5 ukuze ihlale ixesha elide.

Q: Uyithintela njani ingozi ye-trunnion ngexesha lokuthuthwa?
A: Sifaka ii-cap zentsimbi ezisuswayo phezu kwee-trunnions size siqinise imbiza nge-chain lashing ngqo emzimbeni - kungekhona kwii-trunnions. Imiyalelo eneenkcukacha zokuphakamisa nokuthumela ifakiwe.

Q: Ngaba niyazibonelela nge-coating ye-slag enamathelayo kakhulu (umz., i-high-MgO)?
A: Ewe – sine-epoxy coating efakwe kwi-ceramic ekwaziyo ukumelana ne-1,200°C. Isetyenziswa ubukhulu obuyi-2mm kwaye ihlala iinyanga ezi-8–12. Ukuphinda ufake i-epoxy kungenziwa kwindawo leyo.

Q: Ithini iwaranti yakho yeembiza ze-slag eziphakathi?
A: Iinyanga ezingama-24 / imijikelo engama-5,000, nokuba yeyiphi na eza kuqala. Oku kuquka ukuqhekeka kodonga kunye nokungaphumeleli kwe-trunnion. Ukuguguleka kwengubo, ukusetyenziswa kakubi koomatshini, kunye nokusetyenziswa okungafanelekanga akubandakanyiwe.

Q: Ngaba ungabonelela ngeembiza ze-slag ngaphandle komatshini wokugaya (njengomphezulu wangaphakathi otyhidiweyo)?
A: Sicebisa kakhulu ukuba singakwenzi oko. Umatshini wokushicilela ubalulekile ekukhupheni inkunkuma. Nangona kunjalo, ukuba uyazamkela iindleko zokucoca eziphezulu, singakunika ngokwexabiso eliphantsi le-~12%.

Q: Ndingazigcina njani iimbiza ze-slag eziphakathi xa zingasetyenziswa?
A: Gcina kwiiplanga zomthi, ungagcini nje emhlabeni. Zigcine zigqunyiwe ukuze zingapholi imvula kwindawo enye. Jikelezisa iimbiza ezisetyenziswayo ukuze usasaze uxinzelelo lobushushu.

Q: Lingakanani ixesha eliqhelekileyo lokulungiselela i-odolo yembiza ye-slag ephakathi?
A: Kwimikhono eqhelekileyo (iitoni ezingama-20, 30, 40, 50) ene-ZG270-500 okanye i-ZG310-570, ixesha lokuqalisa liziintsuku ezingama-35–45. Kwizixhobo ezikhethekileyo okanye uvavanyo lwempembelelo, yongeza iintsuku ezili-10–15.
