The chikuru zvinoumba refractory zvinhu zvakadai zvidhinha zvinofema, zvidhinha zvemhino, uye zvinokandwa

Refractory zvinhu zvinoshandiswa zvakanyanya musimbi, makemikari tekinoroji, peturu uye petrochemical, kugadzira michina, kugadzirisa magetsi uye mamwe maindasitiri minda, iyo yakawanda yakawanda inoshandiswa muindasitiri yesimbi. Mumarairi esimbi nemavira ekunatsiridza muindasitiri yekugadzira simbi, zvinhu zvinoramba zvichishandiswa nevagadziri vesimbi zvinosanganisira zvidhinha zvinofema, zvidhinha zvidhinha, mavhavha echoto chemagetsi, zvinokandwa, jecha remvura, magnesia kabhoni zvidhinha, nezvimwewo. zvikamu zvikuru uye zvikamu zvakawedzerwa zvakasiyana zvakasiyana. Kubva pakuongorora kwemakemikari, zvinhu zvinoramba zvinoumbwa nemaminerari, akadai se corundum, mullite, magnesia, nezvimwewo. Izvo zvikamu zvikuru zvealumina uye magnesia.

(Mufananidzo) Corundum

Kana iri chikamu chikuru chezvinhu zvinoramba, ndicho chikamu chematrix chinoumba pfuma yerefractory, ndiyo nheyo yehutano hwezvinhu zvinoramba, uye inotarisa zvakananga zvinhu zvezvigadzirwa zvinoramba. Semuenzaniso, zvidhinha zvinofema zvinoda kugadzirwa nepamusoro-soro ore, uye zvino zvakaitwa kuburikidza nemaitiro akaoma uye anonzwisisika, kuitira kuti ave nechokwadi chokuti hupenyu hwezvidhinha zvinofema zvinoshandiswa nevagadziri vesimbi zvinogona kuzadzisa zvinodiwa. Izvo zvakakosha zvezvinhu zvinodzivirira zvinogona kuva oxides (aluminum oxide, magnesium oxide, nezvimwewo), kana zvinhu kana asiri-okisijeni makomisheni (kabhoni, silicon carbide, nezvimwewo).

Zvinoenderana nechimiro chezvikamu zvikuru, zvinhu zvinoramba zvinogona kukamurwa muzvikamu zvitatu: acidic, neutral, uye alkaline. Acid refractory zvinhu zvinonyanya zvinhu zvine acidic oxides sesilicon oxide. Chinhu chikuru chinonzi silicic acid kana aluminium silicate, iyo inoburitsa munyu pasi pekuita kwekushisa kwakanyanya uye alkali. Iyo huru yemakemikari zvinoumba alkaline refractories i magnesium oxide, calcium oxide, etc. Kazhinji refractory zvigadzirwa zvinosanganisira drainage jecha uye ladle masiraidhi. Neutral refractories inonyatso kabhoni uye chromium refractories. Mukuwedzera, high-aluminium refractories (alumina content yakakura kudarika 45%) ndeyekusarerekera refractories iyo inowanzova acidic, nepo chromium refractories inowanzova yakawanda alkaline. Zvezvinhu zvinoramba zvakarerekera kumberi, zvakajairika high-alumina refractory zvinhu zvinosanganisira zvidhinha zvinofema, zvidhinha zvidhinha, uye mavhavha echoto chemagetsi.

Kambani yedu ine makore gumi nemasere ekutsvagisa nekusimudzira, kugadzirwa uye kutengesa kwezvinhu zvinoramba zvakadai sezvidhinha zvinofema, zvidhinha zvidhinha, zvinokandwa, uye mafomula ane patented, dhizaini yakasarudzika, uye kuomesesa uye kwakamisikidzwa kuita kwega rega rega, kuitira kuti vagadziri vesimbi vagone kuzvishandisa. nerugare rwepfungwa nekunyaradzwa.
