High-performance coating material for intermediate frequency furnace
The invention relates to a high-performance coating material for an intermediate frequency furnace, which comprises the following components in percentage by weight: 50 to 60 percent of fused white corundum particles, 20 to 35 percent of white corundum fine powder, 0 to 10 percent of aluminum oxide micro powder, 0 to 10 percent of clay, 0 to 8 percent of silicon micro powder, 0 to 3 percent of chromium oxide micro powder, 0 to 1 percent of plasticizer, 1 to 5 percent of composite additive, and 10 percent of an aluminum dihydrogen phosphate liquid binding agent which is additionally added; wherein the composite additive is composed of citric acid and oxalic acid. The composite additive composed of citric acid and oxalic acid is added, the pH value of the coating material is effectively adjusted, the shelf life of the coating material can be prolonged, the high-temperature strength of the coating material can be enhanced, and therefore the service life of the intermediate frequency furnace lining is prolonged.
本发明涉及一种中频炉用高性能涂抹料中频炉用高性能涂抹料，所述涂抹料的组分及重量百分比为：50％～60％的电熔白刚玉颗粒，20％～35％的白刚玉细粉，0～10％的氧化铝微粉，0～10％的粘土，0～8％的硅微粉，0～3％的氧化铬微粉，0～1％的增塑剂，1～5％的复合添加剂，外加10％的磷酸二氢铝液体结合剂；所述复合添加剂由柠檬酸和草酸组成。本发明通过添加由柠檬酸与草酸组成的复合添加剂，有效调节涂抹料的pH值，既可提高涂抹料的保质期，又能够增强涂抹料的高温强度，从而提高了中频炉炉衬的使用寿命。
