Compact anti-erosion reinforced sintered zirconium oxide big brick and production process thereof
The present invention relates to a compact anti-erosion reinforced sintered zirconium oxide big brick and a production process thereof, wherein the big brick comprises 25-50% of zirconium oxide with a particle size of 5-3 mm, 15-34% of zirconium oxide with a particle size of 3-1 mm, 15-35% of zirconium oxide with a particle size of less than 1 mm, 5-18% of desilication zirconium with a particle size of less than 1 mm, 2-7% of industrial alumina with a particle size of less than 1 mm, 0.5-6% of MS97 magnesia with a particle size of less than 1 mm, 0-3% of magnesium oxide with a particle size of less than or equal to 0.088 mm, 0.05-0.1% of additional sodium ethylene polypropylene, and less than or equal to 0.5% of additional sodium hexametaphosphate. The process comprises casting, sintering and brining, wherein the casting comprises material preparing, material mixing, vibration casting and drying, the drying time is 3-5 h, the sintering temperature is 1600-1650 DEG C, the sintering time is 60-80 h, the thermal insulation time is 4-8 h, and the brining comprises preparing chromic chloride hexahydrate into a 10-30% chromium salt solution, and immersing a brick into the salt solution under a vacuum environment 2-5 times. According to the present invention, the product with the large size and the specific shape can be produced, and the good glass liquid corrosion resistance is provided.
