Kev txhim kho kev ntsuas rau kev tawg ntawm ripper beams
1. Siv cov cuab yeej siv los txhuam qhov chaw vuam ua ntej vuam kom tshem tawm xeb, oxide nplai thiab lwm yam impurities ntawm qhov chaw;
2. Ua qhov chaw vuam;
3. Ua ntej vuam, preheat lub tes tsho iav nrog lub preheating kub ntawm 200 mus rau 250 degree thiab lub sij hawm preheating ntawm 45 feeb;
4. Txhawm rau kom ntseeg tau tias kev nkag mus, qhov tshwj xeeb vuam rau hauv qab vuam yog siab dua cov txheej txheem rau lwm cov txheej, siv vuam tam sim no ntawm 280A, vuam voltage ntawm 30V, thiab cua ntws ntawm 20L / min;
5. Rau peb txheej tom ntej, qhov vuam tam sim no yog 260A, qhov vuam voltage yog 28V, thiab cov cua ntws yog 20L / min;
6. Npog vuam tsis tas yuav tsum tau ua kom muaj kev nkag mus, thiab qhov vuam specification yuav tsum me dua, siv vuam tam sim no ntawm 240A, qhov hluav taws xob ntawm 24V, thiab cua ntws ntawm 20L / min;
7. Tom qab vuam, ua cov txheej txheem tom qab cua sov ntawm qhov vuam thiab qhov chaw muaj kev kub ntxhov (ze ntawm lub tes tsho sab) ntawm qhov kub ntawm li 200 degree rau 30 feeb.
