Problems solved by technology

[0006] The nano-catalyzed metal-ceramic combination non-burning and non-immersing environmentally friendly sliding board of the present invention is to add iron-containing nano-catalysts so that the non-burning sliding board passes through a relatively low temperature zone (600-700°C) during use. , the carbon source is coked into carbon nanotubes. Under the action of a catalyst, this kind of carbon nanotubes with high specific surface area and high reactivity can quickly react with metals to form a ceramic bonding phase, thereby solving the shortcoming of the low-temperature strength of the non-burning slide plate and reducing the slide plate. The sensitivity of the material to temperature improves the strength and reliability of the material

Abstract

The invention relates to a nano-scale catalytic metal-ceramic bonding firing-free bitumen-impregnation-free environment-friendly slide plate and a preparation method thereof. The invention relates to the firing-free bitumen-impregnation-free environment-friendly slide plate and the process thereof. The invention relates to the field of a refractory material. The material comprises the raw materials of 25-40% granular first-grade alumina, 15-25% of tabular corundum, 6-12% of mullite, 6-15% of silicon carbide fine powder, 0.5-1% of clay, 0.5-2% of magnesium boride, 6-10% of zircon sand, 2-5% of aluminum powder, 1-3% of carbon black, 0.5-1.5% of boron carbide, 3-10% of alumina micro-powder, 0.5-1.5% of aluminum fiber, 1-3% of nano-powder ferrosilicon, 1-3% of iron silicon nitride, and 4-6% of a composite resin binder. The process comprises the following steps: resin, polycarboxylic acid and nano-powder are mixed to prepare the composite resin binder; the granular materials are dry-mixed; premixed powder and the binder are added; and mix grinding, aging, molding, drying, strapping, grinding, shell-applying, and packaging are carried out. The process does not require a firing step, such that energy is saved; and bitumen impregnation is not required, such that pollution is avoided. When the slide plate is applied in a continuous-casting large ladle, the slide plate can be used for continuous sliding more than 4 times. The slide plate can also be used in converter slag stopping.
