    摘要： COMPACTED AND BURNED REFRACTORY BODY MADE FROM SIZEGRADED PARTICULATE BATCH MIXTURE OF CHEMICAL GRADE (TRANSVAAL) CHROMITE GRAIN WITH LOW-SILICA CONTENT, DEADBURNED MAGNESITE GRAIN, AND FUSED MAGNESIA-CHEMICAL GRADE CHROMITE GRAIN CONTAINING 53-58% MGO. CHROMITE GRAIN FORMS 10-35% OF BATCH AS -10+150 MESH PARTICLES. OTHER TWO GRAINS FORM THREE PARTICLE FRACTIONS: 3060% OF BATCH BEING COARSE -4+20 MESH, 0-30% OF BATCH BEING INTERMEDIATE -10+35 MESH, AND FINE MAGNESITE GRAIN IS AT LEAST 10% OF BATCH. THE TOTAL +28 MESH PARTICLES OF CHROMITE GRAIN AND MAGNESITE GRAIN CONSTITUTE 4 TO LESS THAN 50% OF BATCH. BODY BURNED AT ABOUT 1600* C. CHARACTERIZED BY MODULUS OF RUPTURE AT 1340*C. CONSISTENTLY ABOVE 1700 P.S.I. AND AS HIGH AS 2000 P.S.I. OR HIGHER.

    摘要： A permeable nozzle is made from MgO and MgO—Al2O3 spinel and has a nonservice backpressure of about 0.5-50 psi at gas flowrates of about 5-20 liters/minute. In one embodiment, the permeable nozzle comprises about 50%-80% of about a 20-48×100 mesh MgO, about 5%-20% of about a 325 mesh MgO and about 5%-40% of about a 48×200 mesh MgO—Al2O3 spinel. In another embodiment, the permeable nozzle comprises about 10%-20% of about a 20-48×100 mesh MgO, about 0%-10% of about a 325 mesh MgO, about 30%-60% of about a 28×48 mesh MgO—Al2O3 spinel, about 10%-40% of about a 48×200 mesh MgO—Al2O3 spinel, and about 10%-20% of about a 325 mesh MgO—Al2O3 spinel.

    摘要： Disclosed herein are a refractory material of high-purity electrofused magnesia clinker having good resistance to corrosion by slag, especially the slag with a high iron content, at high temperatures under an oxidative environment, and a burned or unburned refractory brick made of such refractory material of high corrosion resistance, which is superior in corrosion resistance as well as spalling resistance.The refractory material comprises more than 10 wt. % of electrofused magnesia clinker containing 98.0 to 99.8 wt. % of MgO, less than 0.05 wt. % of SiO.sub.2, and 0.1 to 2.0 wt. % of CaO. It may be in the form of burned or unburned or prepared unshaped refractories.
