IiNkcazelo zamalahle okuCoking: Isikhokelo esiBanzi

Esi sikhokelo sinika inkcazo eneenkcukacha ukupheka iinkcukacha zamalahle, egubungela iimpawu eziphambili, izicelo, kunye nezinto ezichaphazela umgangatho. Funda malunga neentlobo ezahlukeneyo zamalahle, imigangatho yehlabathi, kunye nendlela ezi nkcazo ezichaphazela ngayo amashishini ahlukeneyo. Siza kuphonononga imiba ebalulekileyo ye ukupheka amalahle emisela ukufaneleka kwayo kwizicelo ezahlukeneyo.

Ukuqonda iiPropati zeCoking Coal

Ukupheka amalahle, ekwabizwa ngokuba yi-metallurgical coal, luhlobo oluthile lwamalahle aneempawu ezizodwa ezibalulekileyo ekusebenziseni imveliso yentsimbi. Ngokungafaniyo nezinye iintlobo zamalahle, ukupheka amalahle ibonakala ngokukwazi kwayo ukungena kwinkqubo ebizwa ngokuba yi-coking, ukwenza i-coke structure eyomeleleyo kunye ne-porous xa ishushu ngokungabikho komoya. Le coke iyimfuneko ekunciphiseni intsimbi ekrwada kwiziko lokuqhushumba. Iipropati eziphambili ezimisela umgangatho we ukupheka amalahle ziquka:

Umxholo woMba oguquguqukayo

Izinto eziguquguqukayo zibhekiselele kumalungu amalahle athi abe ngumphunga xa kufudunyezwa. Umxholo osezantsi oguquguqukayo ubonisa ngokubanzi i-coke eyomeleleyo, iyimfuneko kwimisebenzi yesithando somlilo. Umcimbi ophezulu oguquguqukayo unokukhokelela kwisakhiwo se-coke esibuthathaka kunye nokunciphisa ukusebenza kwe-metallurgical.

Isiqulatho sothuthu

Isiqulatho sothuthu simele umbandela wezimbiwa ezingatshiyo kumalahle. Isiqulatho sothuthu oluphezulu sinciphisa ixabiso lokufudumeza kwamalahle kwaye sinokuchaphazela umgangatho wecoke eveliswayo. Isiqulatho sothuthu esisezantsi sikhethwa ngokubanzi.

Umxholo wesulfure

I-sulfure yinto engcolileyo ephawulekayo kumalahle, kwaye amanqanaba aphezulu e-sulfure angakhokelela ekungcoliseni kwendalo ngexesha lokuveliswa kwentsimbi. Umxholo wesulfure osezantsi uyimfuneko ekuthotyelweni kokusingqongileyo kunye nokunciphisa ukukhutshwa. Iiteknoloji ezahlukeneyo kunye neenkqubo ezikhoyo zokujongana ne-high-sulphur ukupheka amalahle, kodwa ukunciphisa isulfure kwasekuqaleni kulungile.

Isiqulatho seCarbon esisigxina

Ikhabhoni esisigxina yikhabhoni engaguqukiyo eseleyo emva kokususwa kwezinto eziguqukayo. Umxholo ophakamileyo wekhabhoni osisigxina unqweneleka ngokubanzi, njengoko uncedisa ngokuthe ngqo kumandla kunye nokuzinza kwe-coke. Isixa sekhabhoni esisigxina sihambelana kakhulu nexabiso le-calorific kunye nesivuno se-coke yamalahle.

Caking Index

Isalathisi se-caking silinganisa ukukwazi kwamalahle ukwenza ubunzima obuhambelanayo ngexesha lokupheka. Iindidi ze-coking ezahlukeneyo ziyafuneka ngokusekelwe kwiimfuno ezithile zesithando somlilo kunye neempawu ezifunwayo ze-coke. Isalathisi esinamandla se-caking sibonisa ukufaneleka kwamalahle kwimveliso ye-coke ephezulu.

ImiGangatho yeHlabathi kunye neNgcaciso ye-Coking Coal

Imibutho eyahlukeneyo yamazwe ngamazwe kunye namazwe aseke imigangatho kunye neenkcukacha ukupheka amalahle. Ezi nkcukacha zichaza uluhlu olwamkelekileyo lweepropati ezikhankanywe ngasentla, ukuqinisekisa umgangatho ongaguqukiyo kunye nokusebenza. Le migangatho ibalulekile ekurhwebeni nasekuqinisekiseni amalahle afanelekileyo kwimveliso yentsimbi. Imizekelo ibandakanya imigangatho ebekwe yi-ISO kunye ne-ASTM International. Ukubambelela kule migangatho kubalulekile kurhwebo lwamazwe ngamazwe kunye nomgangatho wemveliso ongaguqukiyo.

Impembelelo yeNgcaciso zamalahle eCoking kwimizi-mveliso

Iinkcukacha ze ukupheka amalahle ichaphazela ngokuthe ngqo ukusebenza kakuhle kweshishini lentsimbi kunye neendleko ezifanelekileyo. Umgangatho we-coke oveliswayo uchaphazela kakhulu inkqubo yonke yokunciphisa i-iron ore kunye nomgangatho wokugqibela wensimbi. Ukukhetha ukupheka amalahle kunye neenkcukacha ezichanekileyo zibalulekile ekuphuculeni ukusebenza kwesithando somlilo kunye nokuvelisa iimveliso zentsimbi ezikumgangatho ophezulu.

Ukukhetha amalahle okuCoking aLungileyo

Ukukhetha okufanelekileyo ukupheka amalahle ifuna ukuqwalaselwa ngononophelo kweenkcukacha zayo kunye neemfuno ezithile zesicelo esicetywayo. Izinto ezinjengodidi lwesithando somlilo, iipropati ezifunwayo ze-coke, kunye nemimiselo yokusingqongileyo zonke zinefuthe ekukhetheni ukupheka amalahle. Ukubonisana neengcali ze-metallurgical kunye nababoneleli kubalulekile ekukhetheni okulungileyo.

Itheyibhile: Uthelekiso lweePropati zeCoking Coal

Qaphela: Amaxabiso akwitheyibhile ayabonisa kwaye anokwahluka ngokuxhomekeke kuhlobo oluthile lwamalahle kunye nomthombo. Ngalo lonke ixesha ubhekisele kwiinkcukacha ezithile ezinikezelwe ngumthengisi.

Ngolwazi oluthe vetshe malunga nomgangatho ophezulu we-coke ye-metallurgical kunye neemveliso zamalahle, cinga ngokuhlola I-Inner Mongolia i-Xinxin Silicon Industry Co.,Ltd. Bangumnikezeli ohamba phambili kwishishini.

I-Disclaimer: Le ngcaciso yenzelwe iinjongo zemfundo kuphela kwaye akufanele ithathwe njengengcebiso yobungcali. Hlala udibana neengcali ezifanelekileyo kwizicelo ezithile kunye neemfuno.
