Umbuzo: zeziphi ezona zinto zintle zokugquma kunye neenkqubo zokufaka izicelo zokuphoswa kwentsimbi enkulu kunye nokuphoswa kwentsimbi?

IMPENDULO: I-ASK iphuhlise utyatyazo oluluqilima oluluqilima oluneempawu eziphuculweyo zokuphelisa ukuncamatheliswa kwesanti kwicandelo elishinyeneyo lentsimbi kunye nentsimbi, kodwa ayifanelekanga kwintsimbi yemanganese efuna i-substrate ekhethekileyo yokulahla.

Ukongeza kumthamo opheleleyo wesinyithi, uxinzelelo lwentloko kunye nobushushu obuphezulu bokuphosa kunokukhokelela kwiimeko ezinzima kakhulu zokuphosa xa ugalela icandelo elikhulu, elikhulu (elingaphezulu kwe-150 ~ 200 mm) ukuphosa kunye nokuphosa.Ukulawula ezi ziphumo kunye nefuthe lazo ekungeneni kwesikhunta kufuna ukuqulunqwa okukodwa kwengubo enokuseka kwaye isebenze njengesithintelo kwi-mold / metal interface.

Ukuze ufumane indawo yokuphosa egudileyo kunye negudileyo kwisicelo esinjalo, ukhetho oluchanekileyo lwe-refractory coating lubaluleke kakhulu.Ipeyinti kufuneka yenze i-coating eyomeleleyo ngokwaneleyo ukukhusela isinyithi ekudibaneni nesanti.Ukufumana ukugquma okutyebileyo ngokwaneleyo ukufezekisa oku, kungafuneka iileya ezininzi zokwaleka.Ubushushu obuveliswa kukutsha phakathi kwemigangatho emibini kufuneka bukwazi ukumelana ngaphandle kogwebu, kwaye indawo epeyintiweyo yokubumba kufuneka yome kakuhle phambi kokuba isinyithi esinyibilikisiweyo sifakwe.

U-ASK uphuhlise iSOLITEC?I-ST 909 inokuhlangabezana nezi mfuno zibalulekileyo zokusebenza.

I-SOLITEC ST 909 yingubo yendalo yonke enokuthi igqitywe nge-flowcoating, i-spray coating, i-dip coating, i-brush coating, njl. ukugquma ukusuka eluhlaza okwesibhakabhaka xa umanzi ukuya kumthubi okhanyayo xa womile.

Xa usebenzisa i-multilayer coating, imfanelo "yokuguqulwa kombala" ibaluleke kakhulu.Ngaphezulu kwengubo yangaphambili, isambatho ngasinye esilandelayo siyabonakala.Kubalulekile ukuba uqaphele ukuba umbala wokuqala wesanti unokuba nefuthe elithile kumbala wokugqibela wengubo.Ngokuqhelekileyo, i-coating iya kubuyela eluhlaza okwesibhakabhaka ukuba amanzi akhona okanye aphinde afakwe kwi-core / cast.
