1. Isisombululo soNyango lobushushu
Inkcazo ngokubanzi yokulungiswa kokushisa kwesisombululo kukuba: ukufudumeza ukuphosa kwi-950 ° C - 1175 ° C kunye nokuyibeka emanzini, ioli okanye umoya emva kokugcinwa kobushushu ukutshabalalisa ngokupheleleyo i-carbides kwinsimbi engenasici ukuze ufumane isakhiwo sesigaba esisodwa. Ukukhethwa kweqondo lokushisa kwesisombululo kuxhomekeke kumxholo wekhabhoni kwintsimbi ephosiweyo. Okukhona uphezulu umxholo wekhabhoni, kokukhona ubushushu besisombululo esiluqilima bufunekayo.
Ukuze kuncitshiswe iqondo lobushushu umahluko phakathi komphezulu wokugalela intsimbi kunye nondoqo ngexesha lenkqubo zokufudumeza, indlela zokufudumeza unyango isisombululo austenitic steel stainless kufuneka preheated kwiqondo lobushushu eliphantsi kwaye ifudunyezwe ngokukhawuleza kwiqondo lobushushu isisombululo. Ixesha lokubamba kufuneka linyuke ngokuhambelanayo njengoko ubuninzi bodonga lokuphosa bukhula.
Indawo yokupholisa yonyango lwesisombululo ingamanzi, ioli okanye umoya, apho amanzi asetyenziswa kakhulu. Ukupholisa komoya kulungele kuphela ukuphoswa kwentsimbi ebhityileyo.

2. Uzinziso
I-Austenitic steel stainless inokumelana ne-corrosion ebalaseleyo emva konyango lwesisombululo. Nangona kunjalo, xa i-casting iphinda ifudunyezwa kwi-500 ° C-850 ° C okanye i-casting isebenza kolu luhlu lweqondo lokushisa, i-chromium carbide iya kuphinda iphinde ibuyele kumda we-austenite grain, ibangele ukubola komda weenkozo okanye i-weld cracking. Lo mcimbi ubizwa ngokuba yi-sensitization. Ukuze kuphuculwe i-intergranular corrosion resistance of such austenitic stainless steel castings, ngokuqhelekileyo kuyimfuneko yokongeza izinto ezixubileyo ezifana ne-titanium kunye ne-niobium. Emva kokunyanga isisombululo, phinda ufudumeze kwi-850 ° C - 930 ° C, uze upholise ngokukhawuleza. Ngale ndlela, i-carbides ye-titanium kunye ne-niobium iqala ukugqithiswa kwi-austenite, ngaloo ndlela ikhusela imvula ye-chromium carbide kunye nokuphucula ukuxhatshazwa komda wengqolowa yentsimbi engenasici.
