Qhov tseem ceeb ntawm kev siv cov cua kub cua sov:
Raws li kev txheeb xyuas ntawm "2013-2017 Tuam Tshoj Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Kev Lag Luam Kev Lag Luam Kev Pom Zoo thiab Kev Hloov Kho thiab Txhim Kho Kev Tshawb Fawb Tshaj Tawm", kev siv cov tshuab hluav taws xob hluav taws xob feem ntau yog hauv tsib yam nram qab no:
1. Kev kho cua sov: ib nrab lossis ib qho quenching, annealing, tempering thiab diathermy ntawm ntau yam hlau;
2. Kub sib sau: tag nrho daim forging, ib nrab forging, kub ntxhov siab, kub dov;
3. Welding: brazing ntawm ntau yam khoom hlau, vuam ntawm ntau yam cuab yeej, saw hniav, steel kav, tooj liab yeeb nkab vuam, thiab vuam ntawm tib yam sib txawv hlau;
4. Hlau smelting: (nqus) smelting, casting molding thiab evaporation txheej ntawm kub, nyiaj, tooj liab, hlau, txhuas thiab lwm yam hlau;
5. Lwm daim ntawv thov ntawm lub tshuab cua kub zaus: semiconductor ib leeg siv lead ua kev loj hlob, kub haum, lub raj mis lub qhov ncauj thaum tshav kub kub sealing, tshuaj txhuam hniav ntawm daim tawv nqaij kub sealing, hmoov txheej, hlau implantation yas.
