Magnesium-carbon brick inogadzirwa zvinobudirira seimwe ye magnesium-carbon refractories pakati pemakore ekuma1960,; Magnesium-kabhoni zvidhinha zvakashandiswa zvakanyanya mukugadzira simbi saka yave kushandiswa kwechinyakare kwegraphite. Aluminium-kabhoni zvidhinha searuminiyamu-kabhoni refractory zvinhu inonyanya kushandiswa kuenderera mberi kukanda, chivharo chekudzivirira chesimbi yakatsetseka billet self-positioning pombi, yepasi pemvura nozzle uye mafuta tsime rinoputika dhiramu, etc. Crucible yakagadzirwa negraphite kugadzira uye inodzivirira moto cauldrons uye zvigadzirwa zvine hukama, zvakadai seyakajairwa crucible, curved mutsipa bhodhoro, plug uye nozzle, vane yakakwira moto kuramba, kuderera kwekuwedzera kwemafuta, kunyunguduka kwesimbi, nekupinzwa kwesimbi uye kukukurwa kwakagadzikana zvakare, kugadzikana kwakanaka kwekushisa kwekushisa uye yakanakisa kupisa kwekushisa pakupisa kwakanyanya. , Saka graphite uye zvigadzirwa zvayo zvine hukama zvinoshandiswa zvakanyanya mukugadzira simbi yakananga kunyungudika.
