Spinel zvicherwa zvine pesvedzero yakakosha pane yakakwirira-tembiricha zvivakwa zve refractory zvinhu. Semuenzaniso, nekuda kweiyo diki yekupisa yekuwedzera coefficient ye spinel (α=8.9x10-*/℃ pa 100 ~ 900 ℃), spinel inoshandiswa sechinhu chinosunga (Kana inonzi cementing phase, matrix), magnesia-alumina zvidhinha ne periclase. sechikamu chikuru chekristaro, kana tembiricha ichichinja zvakanyanya, kushushikana kwemukati kunoitwa kudiki, uye zvidhinha hazvisi nyore kuputsa, saka kugadzikana kwekupisa kwezvidhinha kunogona kuvandudzwa (magnesia-alumina zvidhinha Kugadzikana kwekupisa kuri 50 ~ 150. nguva).
Pamusoro pezvo, nekuti spinel ine zvinhu zvakanaka senge kuomarara kwepamusoro, kugadzikana kwemakemikari zvimiro, uye yakakwira kunyungudika, uye inoshingirira mukuora nekunyungudika kwakasiyana pakupisa kwakanyanya, kuvapo kwemaminerari espinel muzvigadzirwa kwakavandudza Kupisa kwekushisa kwe. chigadzirwa.
Chikonzero chikuru nei kupisa-kupisa kunyorovesa tembiricha ye magnesia-alumina zvidhinha (pokutangira isiri pasi pe1550-1580 ℃) yakakwira kupfuura yezvidhinha zvemagnesia (pokutangira iri pazasi 1550 ℃) ndechekuti matrix maumbirwo akasiyana. .
Kupfupisa, spinels zvinhu zvakanakisa maererano nekunyunguduka, kuwedzera kwekupisa, kuoma, nezvimwewo, zvine chimiro chemakemikari chakagadzikana, kupikisa kwakasimba kune alkaline slag erosion, uye kushorwa nekunyungudutswa kwesimbi yakanyungudutswa. .
Junsheng yakakwira-kuchena magnesium-aluminium spinel system inoshandisa yakakwirira-kuchena alumina uye yakakwirira-kuchena magnesium oxide seyakagadzirwa zvinhu, uye inoputirwa pakupisa kwakanyanya. Zvinoenderana neakasiyana makemikari anoumbwa, akakamurwa kuita mamakisi matatu: SMA-66, SMA-78 uye SMA-90. Product Series.
Junsheng high-purity magnesia-aluminium spinel ine yakanyanya kuderera tsvina yemukati uye yakanakisa yepamusoro-tembiricha kuita. High-purity spinel inokodzera nzvimbo dzakagara dzakagadzirwa sezvidhinha zvinofema, zvidhinha zvechigaro, ladles, electric furnace top covers, refractory materials for rotary kilns, and refractory materials for smelting alloys. zvigadzirwa, pamwe ne spinel-ine maumbirwo seti.
Zvigadzirwa zvinogona kubatsira kunatsiridza iyo slag corrosion kuramba yezve refractory zvinhu, uye kugadzirisa dambudziko rekutsemuka kwezvinhu kunokonzerwa nekuwedzera magnesium mbishi zvinhu.
