Imiba efuna ingqalelo xa usebenzisa iqondo lobushushu eliphezulu muffle eziko

1. Xa i-furnace ye-muffle ephezulu yokushisa isebenza, i-workpiece kufuneka ithathwe ngokucophelela ukuze ugweme ukutshisa ngenxa yokushisa okukhulu; nikela ingqalelo kumthamo womthwalo we-workpiece kwiziko ukuba ungabi mkhulu kunepleyiti ephantsi yomlilo.

2. Ekuqaleni kokusetyenziswa, umqhubi kufuneka aqale ahlole ukuba kukho iifayili zentsimbi kunye nezinye izinto ezishiyekileyo kwisithando somlilo esiphezulu. Ukuba zifunyenwe, kufuneka zicocwe ukuze zigweme isiphaluka esifutshane xa iifayili zentsimbi ziwa. .

3. Ubushushu kufuneka buphakanyiswe kwaye buthotywe rhoqo ngokweemfuno eziguqukayo ze-workpiece; ukwenzela ukuba kuqinisekiswe ukuba i-workpiece inokutshiswa ngokufanelekileyo kwisithando somlilo, musa ukuvula umnyango ngokungaqhelekanga ngexesha lokusebenza;

4. I-workpiece efakwe kwisithando somlilo kunye ne-thermocouple efakwe kwisithando somlilo akufanele ichukumise; i-furnace ye-muffle ephezulu kufuneka ihlolwe kwaye ilungiswe ngexesha.
