Graphite crucible refractory tembiricha

Graphite ine huwandu hwakakura kwazvo hwekushandisa uye ndeimwe yemaminerari anoramba kutonhora kwakanyanya. Kufanana nema graphite crucibles, iwo akagadzirwa echisikigo graphite mbishi zvinhu uye anochengeta iwo ekutanga akanakisa zvimiro zvegraphite. Chii chinonzi refractory tembiricha ye graphite crucible?

Zvakanakira zve graphite crucible:

1. Fast heat conduction speed, high density, kuderedza kupera nguva, kuchengetedza simba, kugadzirwa kwepamusoro, uye kuchengetedza manpower.

2. Uniform chimiro, chaiyo strain resistance uye yakanaka kugadzikana kwemakemikari.

3. Kudzivirirwa kwezvakatipoteredza, kuponesa simba, corrosion resistance, acid uye alkali resistance, nezvimwewo.

Mufananidzo: Graphite crucible

Kufanana nemhangura yedu yesimbi yakajairwa, aluminium, goridhe, sirivheri, lead, zinc uye alloys, zvese zvinogona kunyungudutswa kuburikidza negirafu socket. Zvinogona kuonekwa kuti tembiricha iyo graphite crucible inogona kumira yakakwira kupfuura nzvimbo yekunyungudika kwesimbi idzi.

Kunyungudika kwegraphite i3850°C±50°, uye painofashaira i4250°C. Graphite chinhu chakachena kwazvo, shanduko yerudzi rwekristaro. Simba rayo rinowedzera nekuwedzera kwekushisa. Pa2000 ° C, kusimba kwegraphite kunowedzera kaviri. Kunyangwe kana ichipisa tembiricha yepamusoro-soro arc kupisa, kurasikirwa nehuremu kudiki kwazvo, uye iyo yekupisa yekuwedzera coefficient zvakare idiki kwazvo.

Yakakwira sei tembiricha yepamusoro yekupikisa kwegraphite crucible? Izvo zvakare zvinokwanisika kusvika 3000 madhigirii, asi mupepeti anokurudzira kuti tembiricha yako yekushandisa haifanire kudarika 1400 madhigirii, nekuti zviri nyore kuve oxidized uye kwete kusimba.
