Lub luag haujlwm tseem ceeb thiab Scope ntawm daim ntawv thov rau Molten Iron Lim

Lub hom phiaj tseem ceeb ntawm kev siv cov ntxaij lim dej yog los ntxuav cov hlau molten, yog li txhim kho qhov zoo ntawm qhov kawg castings.

1. Lim thiab Purification: cuam tshuam zoo uas tsis yog- hlau impurities - xws li oxide inclusions, slag, thiab molding xuab zeb - muaj nyob rau hauv cov hlau molten, yog li txo qhov tsis xws luag hauv cov castings xws li slag inclusions thiab porosity.

2. Kev Txhim Kho Kev Ua Haujlwm: Los ntawm kev txo qis hauv cov hlau molten thiab refining cov qauv nplej, cov ntxaij lim dej txhim kho cov castings ' tensile lub zog, elongation, thiab tag nrho cov cuab yeej cuab tam, thaum tib lub sij hawm txo cov seem seem.

3. Siv tau Castings: Siv dav hauv kev tsim cov hlau cam khwb cia grey, cov hlau nplaum, thiab me me - nplai steel castings; lawv yog cov tshwj xeeb zoo - haum rau cov khoom uas yuav tsum tau nruj me ntsis hauv cov qauv zoo.
