Anfani

● Iyanrin alawọ ewe. Ailewu si ayika ni akawe pẹlu silica (silicosis) ati iyanrin zircon
● High refractoriness (＞1800°C)，can be used for casting various materials. There is also no need to use different sand type according to material.
● Iwọn atunṣe giga. Mejeeji Gbona ati isọdọtun ẹrọ. Nfunni igbesi aye iṣẹ to gun ati idinku lilo iyanrin.
● Ikojọpọ giga. Apẹrẹ iyipo seramiki sintered ti a fiwewe pẹlu awọn oka ti o ni irisi angula ngbanilaaye fun iyapa irọrun lati awọn ẹya simẹnti ati ilọsiwaju collapsibility ti o yọrisi ajẹku kekere ati ṣiṣe simẹnti.
● Ṣiṣan omi ti o dara julọ ati ṣiṣe kikun nitori jijẹ iyipo.
● Isalẹ Gbona Imugboroosi ati Imudara Ooru. Awọn iwọn simẹnti jẹ deede diẹ sii ati iṣiṣẹ kekere n pese iṣẹ mimu to dara julọ.
● Isalẹ olopobobo iwuwo. Bi iyanrin seramiki atọwọda jẹ nipa idaji bi ina bi iyanrin seramiki ti a dapọ (iyanrin bọọlu dudu), zircon ati chromite, o le tan jade ni iwọn meji awọn molds fun iwuwo ẹyọkan. O tun le ṣe ni irọrun ni irọrun, fifipamọ iṣẹ ati gbigbe awọn idiyele agbara. Bibẹẹkọ, akiyesi yẹ ki o fi fun iye afikun ohun elo.
● Nilo 40-50% kere resini.
● Awọn simẹnti ti wa ni bo pẹlu kekere tabi ko si.
● Le ṣee lo bi iyanrin kan.
● Iduroṣinṣin ipese. Agbara ọdọọdun 200,000 MT lati tọju iyara ati ipese iduroṣinṣin.
