④ Yuav ua li cas FeSiN txhim kho thermal poob siab nyob rau hauv refractories?
Thermal shock tsis ua hauj lwm yog ib qho ntawm feem ntau ua rau refractory puas nyob rau hauv blast furnace ib puag ncig. Kev hloov pauv sai sai ua rau muaj kev ntxhov siab sab hauv vim tsis sib xws thermal expansion.
FeSiN txhim kho thermal poob siab los ntawm kev tsim nyob rau hauv -situ silicon nitride bonding theem thaum lub sij hawm siab - kub raug. Cov theem no ua raws li cov txheej txheem buffers uas faib cov thermal kev nyuaj siab ntau sib npaug ntawm cov refractory matrix.
Vim li ntawd,siab nitrogen ferrosilicon nitridetxo qhov tawg tawg thiab txhim kho cov txheej txheem kev ncaj ncees nyob rau hauv cyclic cua sov tej yam kev mob, tshwj xeeb tshaj yog nyob rau hauv taphole thiab khiav systems.
⑤ Vim li cas Ferrosilicon Nitride txhim kho slag corrosion kuj?
Slag corrosion tshwm sim thaum molten slag penetrates refractory pores thiab chemically reacts nrog cov qib sib txuas, ua rau cov txheej txheem degradation.
FeSiN txhim kho slag kuj los ntawm kev txo qhov qhib porosity thiab tsim cov tshuaj ruaj khov Si₃N₄ tes hauj lwm. Cov tes hauj lwm no ua raws li kev tiv thaiv kev tiv thaiv tawm tsam slag infiltration thiab txo cov tshuaj tiv thaiv kab mob.
Hauvferrosilicon nitride rau kub hlau khiavdaim ntaub ntawv, qhov no ua rau qeeb hnav tus nqi thiab txhim kho nto stability nyob rau hauv tas li slag ntws tej yam kev mob.
⑥ FeSiN ua li cas txhim kho siab - qhov kub thiab txias zog?
Bonding lub zog nyob rau hauv refractories nyob ntawm lub stability ntawm lub matrix nyob rau hauv tshav kub thiab load. Cov kab ke niaj hnub feem ntau tsis muaj zog vim yog theem decomposition ntawm qhov kub siab.
FeSiN pab txhawb rau siab -kub sib txuas los ntawm kev tsim cov theem nitride ruaj khov uas txhawb nqa cov ciam teb. Qhov no txhim kho kev thauj khoom- cov kabmob muaj peev xwm thiab tiv thaiv cov qauv kev sib tsoo hauv qhov cub tawg.
Qhov no mechanism yog tshwj xeeb tshaj yog tseem ceeb nyob rau hauvblast furnace refractory bonding khoomcov tshuab uas yuav tsum tau muaj lub neej ntev kev sib tw thiab kev ruaj ntseg tshuab.
