1. Khoom siv: ZG35---42:
2. Cov txheej txheem ua haujlwm
(1) Casting: Casting xyuas kom meej tias cov khoom tsis sib xws thiab tsis muaj pores thiab hlwv, thiab tom qab ntawd annealed.
(2) Thaum ntxhib tig qhov khoob ntawm lub tshuab dhos, tawm ntawm 2 ~ 3mm rau sab hauv txoj kab uas hla, thiab sab nraud txoj kab uas hla yog 6 ~ 7 hli me dua qhov loj me.
(3) Overlay welding: Preheat lub log tsav ua ntej mus rau qhov kub ntawm 200 degrees, ua kom sov li 1 mus rau 2 teev, thiab tom qab ntawd welded tawm ntawm qhov cub. Siv LG834 vuam hlau + HJ260D flux + SJ102 flux los vuam lub log thiab lub xub pwg kom ntseeg tau tias tsis muaj kab nrib pleb hauv txheej vuam. , slag inclusions thiab lwm yam tsis xws luag.
(4) Tom qab qhov chaw vuam, ua cov txheej txheem annealing nrog cov cua kub ntawm 850 ~ 860 degrees, tuav lub sij hawm ntawm 5 teev, thiab tom qab ntawd txias hauv qhov cub. Thaum lub log kub qis dua 300 degrees, nws tuaj yeem ua cua txias tawm ntawm qhov cub. (5) Sab hauv thiab sab nraud qhov ntev ntawm lub tsheb zoo yog raws li qhia hauv daim duab.
