Iindaba

Kwindawo yokuvelisa eguqukayo, ishishini lentsimbi lilitye lesiseko leziseko zophuhliso zanamhlanje. Njengoko imfuno yentsimbi yehlabathi iqhubeka ikhula, abavelisi baya beguqukela ngakumbi kubuchwepheshe obutsha ukuze bandise ukusebenza kakuhle, banciphise iindleko kwaye baphucule umgangatho wemveliso. Phakathi kwezi nkqubela phambili, i-Continuous Casting Machine (CCM) ivele njengotshintsho olukhulu, iguqula inkqubo yokuvelisa intsimbi kwaye ibeka imigangatho emitsha kushishino.

Qondaumatshini wokuphosa oqhubekayo

Ukuphoswa okuqhubekayo yinkqubo eguqula ukuhamba okuqhubekayo kwesinyithi esinyibilikisiweyo sibe yimveliso yesinyithi esiqinileyo ngaphandle kwesidingo seendlela zemveli zokuphoswa kwe-ingot. Ii-casters eziqhubekayo zidlala indima ebalulekileyo kule nkqubo, ziphosa isinyithi esinyibilikisiweyo ngqo kwiimilo ezigqityiweyo ezifana neeslabs, iintyatyambo kunye neebhilethi. Le ndlela ayigcini nje ngokwenza imveliso ibe lula kodwa ikwanciphisa kakhulu ukusetyenziswa kwamandla kunye nenkunkuma yezinto.

Inkqubo yokuphosa eqhubekayo iqala ngokunyibilikisa izinto eziluhlaza kwisithando sombane okanye kwisiguquli seoksijini. Xa intsimbi ifikelele kubushushu obufunekayo kunye nokwakheka kwayo, igalelwa kwi-tundish, esebenza njengetanki yokubamba yokufaka intsimbi enyibilikisiweyo kwi-casting mold. I-mold idla ngokupholiswa ngamanzi, ivumela umaleko wangaphandle wentsimbi ukuba uqine ngelixa inxalenye yangaphakathi ihlala inyibilikile. Njengoko intsimbi iqina, isuswa rhoqo kwi-mold, yiyo loo nto ibizwa ngokuba yi-"continuous casting".

Iingenelo zomatshini wokuphosa oqhubekayo

Ukwaziswa kwee-casters eziqhubekayo kuzise iingenelo ezininzi kunye nokuveliswa kwentsimbi eguquliweyo:

1. Phucula ukusebenza kakuhle

Ukongeza, ukunciphisa ukudibana kwentsimbi enyibilikisiweyo nomoya kunokunciphisa umngcipheko wongcoliseko kwaye kuphucule umgangatho wemveliso ngakumbi.

3. Nciphisa inkunkuma yezinto eziphathekayo

Iindlela zokuphosa zemveli zihlala zibangela inkunkuma enkulu yezinto ezibonakalayo ngenxa yesidingo sokusika nokulungisa i-ingot. Kwelinye icala, oomatshini bokuphosa ngokuqhubekayo bavelisa iimilo ezikufutshane ne-net ezifuna ukugqitywa okuncinci. Ukunciphisa inkunkuma akunciphisi nje iindleko zemveliso kodwa kukwanegalelo kwizenzo zokuvelisa ezizinzileyo.

4. Nciphisa ukusetyenziswa kwamandla

Ukusebenza kakuhle kwamandla yingxaki ephambili kwimveliso yentsimbi, kwaye ii-casters eziqhubekayo zisombulula le ngxaki ngempumelelo. Ukuphoswa rhoqo kunciphisa ukusetyenziswa kwamandla ngokubanzi ngokuphelisa isidingo samanyathelo okucubungula aphakathi njengokuphinda kufudunyezwe kwaye kunyibilikiswe. Oku akunciphisi nje iindleko zokusebenza kodwa kuhambelana nemizamo yehlabathi yokunciphisa ukukhutshwa kwekhabhoni kwimveliso.

5. Ukuguquguquka kunye nokuguquguquka kwezinto

Ii-casters zanamhlanje eziqhubekayo zenzelwe ukwamkela uluhlu olubanzi lweendidi zentsimbi kunye nobukhulu beemveliso. Oku kuguquguquka kuvumela abavelisi ukuba baphendule ngokukhawuleza kwiimfuno zemarike ezitshintshayo kwaye benze ngokwezifiso iimveliso zabo. Nokuba bavelisa intsimbi enamandla aphezulu kwiimoto okanye ii-alloys ezikhethekileyo zokwakha, oomatshini bokuphosa abaqhubekayo bahlangabezana nayo yonke imfuneko.

Impembelelo kwishishini lesinyithi

Ukwaziswa kwe-constant caster kube nefuthe elikhulu kwishishini lesinyithi, kwatshintsha iindlela zokuvelisa kunye nokukhuthaza uphuhliso. Njengoko abavelisi besamkela obu buchwepheshe, kuye kwavela iindlela ezininzi eziphambili:

1. Ukuzenzekelayo kunye noKwenziwa kweDijithali
