Ukuphola kweMetal Casting

Ukugodola yimathiriyeli ebandayo ebekwe ngaphakathi komngxuma, umphezulu womgodi kunye nangaphakathi komngundo ukuze kukhawuleziswe isantya sokupholisa sasekhaya sokugalela. Ukugodola kusetyenziswe ngokudibeneyo nenkqubo yokungena kunye nenkqubo yokunyuka ukulawula ukulandelelana kokuqina kwee-castings ukufumana ukuphosa okufanelekileyo.

I-Chilled yohlulwe ibe yingqele yangaphakathi kunye ne-external ingqele. Ibhloko yentsimbi ekhenkcezayo ebekwe emngxunyeni kwaye inokunyibilika kwi-casting ibizwa ngokuba yingqele yangaphakathi; ngelixa ibhloko yentsimbi ebandayo ebekwe kumphezulu wepateni (okanye ibhokisi engundoqo) ibizwa ngokuba yingqele yangaphandle. I-chills yangaphakathi ekugqibeleni iya kuba yinxalenye ye-castings, ngoko kufuneka yenziwe ngezinto ezifanayo kunye nokuphosa. Iingqele zangaphandle zinokuphinda zisetyenziswe kwaye zisetyenziswe kwakhona.

 

Izinto zokuNqanda:

Izinto zeMetallic: intsimbi ephezulu yekhabhoni, intsimbi yekhabhoni ephakathi, intsimbi ekhandiweyo, ubhedu olutyhidiweyo, i-aluminiyam okanye izinto ezifanayo nezifunwayo.
Izinto ezingezizo iMetallic: isanti ye-zircon, igraphite, isanti ye-carbon, i-chrome magnesia, isanti ye-chrome, i-magnesia.

 

Imisebenzi ye-Chills:

1) Nciphisa ubungakanani bokunyuka kwaye ukwandise izinga elifanelekileyo. Uqheliselo lubonisile ukuba ngokusetyenziswa okufanelekileyo kweengqele kunye neteknoloji yokunyuka kwe-thermal insulation riser, ireyithi eqinisekisiweyo yokujulwa kwentsimbi yokugqibela ingaba phezulu kakhulu.
I-2) Ukubeka i-chills kwindawo efanelekileyo yokuphosa kunokuphucula umjelo wokutya. Inokuphucula umgangatho wangaphakathi wobunjani bokuphosa kunye nokubonelela ngekhwalithi ephezulu.
3) Ukusetyenziswa kokugodola ngokubambisana nenkqubo yokunyuka kunokunyusa umgama wokutya wokunyuka.
I-4) Ukuphelisa uxinzelelo lwe-thermal yendawo kunye nokuthintela ukuqhekeka. Ukwenziwa kwentsimbi enkulu, isanti yechromate okanye isanti ye-zircon enesiphumo esihle sokupholisa kufuneka isetyenziswe.
I-5) Ukubeka i-chills kunokukhawulezisa izinga lokuqiniswa kokuphosa, ukucokisa ukwakheka kweenkozo, kunye nokuphucula iimpawu zomatshini zokuphosa.
