④ Yuav ua li cas FeSiN thiab Si₃N₄ coj txawv txawv nyob rau hauv steelmaking ib puag ncig?
Hauv metallurgical systems, Ferrosilicon Nitride plays lub luag haujlwm tseem ceeb hauv kev hloov kho refractory microstructure. Thaum lub sijhawm ua haujlwm siab - kub, nws tso cov nitrogen thiab tsim cov Si₃N₄ txuas ntxiv rau theem hauv -situ, txhawb cov refractory matrix.
Tus cwj pwm no ua rau nws muaj txiaj ntsig zoo li arefractory yaig kuj additive, tshwj xeeb tshaj yog nyob rau hauv cov tshuab raug molten slag ntws thiab thermal cycling, xws li taphole av nplaum thiab cov kab khiav.
Silicon Nitride (Si₃N₄), txawm li cas los xij, yog tshuaj lom neeg ruaj khov tab sis tsis muaj zog hauv cov tshuaj tiv thaiv metallurgical. Nws tsis nquag koom nrog kev sib koom ua ke hauv cov refractories thiab tsis yooj yim rau kev faib khoom sib xws hauv cov khoom sib xyaw refractory.
Qhov no yog vim li casFeSiN refractory additive tsum khoomyog nyiam nyob rau hauv steel nroj tsuag, thaum Si₃N₄ tseem yog ib tug niche ceramic khoom.
⑤ Vim li cas Ferrosilicon Nitride siv dav dua li Silicon Nitride hauv steelmaking refractories?
Lub ntsiab yog vim li cas yog cov txheej txheem compatibility.
Ferrosilicon Nitride integrates ib txwm ua rau steelmaking refractory systems xws liFeSiN rau Al2O3-SiC-C refractorythiabblast furnace refractory bonding khoomcov qauv. Nws reacts thaum lub sijhawm ua haujlwm ntawm lub cub tawg thiab txhim kho ob qho tib si thermal shock thiab slag kuj.
