Amanqaku okuNikwa ingqalelo ekusebenziseni umatshini wokuFudumeza oRhoqo oPhezulu weSikhokelo soLoliwe esiCinywayo

Xa sisebenzisa i Isantya esiphezulu sokufakwa kumatshini wokufudumeza kunye nesixhobo somatshini wokucima ukucima iileyili zesikhokelo, kufuneka sinikele ingqalelo kwezi ngongoma zilandelayo:

a. Ukukhethwa kwesantya sokuhamba komatshini Phantsi kweemeko ezithile zezinye iiparameter zenkqubo, ukucotha isantya sokuhamba, kokukhona kuya kubanzima umaleko obukhuni, kodwa ukusebenza kwemveliso kuncitshisiwe. Ukuba isantya ezihamba icotha kakhulu, yobulukhuni kumphezulu kuya kuncitshiswa, ngoko ke isantya ihamba kufuneka ilawulwe ngaphakathi kuluhlu 1.2 ～ 3mm / s.

b. Ukukhetha ukucima ubushushu bokufudumeza sisitshixo. Obona bushushu bufanelekileyo bokufudumeza bokucima kufuneka bube ngaphezulu kweqondo lobushushu, kunye nendawo yokunyibilika ye-phosphorus eutectic engaphantsi kwe-957 ° C. Ngokubanzi, uluhlu lobushushu lwe-900-950 ° C lufanelekile.

c. Ukucima okuphakathi: Ngenxa yobuninzi begraphite kwi-iron cast, iqondo lokudlulisa ubushushu liyancitshiswa, kwaye kwangaxeshanye, ifuthe le-Si kunye ne-Mn element 1 linciphisa izinga lokupholisa elibalulekileyo. Ke ngoko, ubushushu obuphezulu bokushushubeza ubushushu bokucinywa kweentsimbi zentsimbi akufuneki ukuba kupholise amandla aphezulu okucima. Ngokubanzi, amanzi etephu afafazwa ukupholisa, kwaye uxinzelelo lwamanzi yi-0.1 ～ 0.15MPa.
