ZrB2 with high temperature ( "3000 ° C) with iron characteristics and the same high conductivity, also has excellent resistance to molten metal and slag corrosion characteristics. To more effectively molten hot metal, usually ZrB2 as induction furnace refractory lining materials, But ZrB2 refractories high conductivity makes lining materials heating long time. Japan's Asahi Glass Ceramic Ltd staff through research additives on ZrB2 refractories corrosion resistance energy and the impact of the conductivity and found ZrB2 - ZrO2 material very promising. ZrB2 content with the increase in the ZrB2 refractories corrosion resistance performance has been enhanced. The experiment is the ZrB2 adding a certain amount of ZrO2 and a small amount of silica produced ZrB2 - ZrO2 castable Liu, in the hope of casting material has excellent corrosion resistance and low conductivity. Lining the chemical composition and characteristics of ZrB2 content 50%, 45% ZrO2 content, the other 5%. the volume density of 4.350 g/cm3, porosity of 8.2%, at room temperature flexural 6.6MPa. Lining material corrosion resistance through its capacity to put in a ton, with molten hot metal and slag RF induction furnace, melting-insulation - casting repeat testing after 50. Erosion requirements until the end of the experiment, the hot metal and slag are to be stable to melt, and lining temperature no higher non-normal. According to results available, lining material damage to the parts of the surface are smooth, the connection was not damaged. Section lining material microstructure revealed that only a small cracks exist, and no infiltration of hot metal materials. Lining material in the back, ZrB2 minor oxidation. This may be related to air the oxygen reaction. After 50 cycles erosion experiments, the material thickness of the depletion of 16 ~ reguirements. This data is about the thickness of magnesia refractories loss of 1 / 40. This new ZrB2 - zirconia material has excellent corrosion resistance properties, induction furnaces can be used as a refractory lining.
