High-toughness ferrosilicon alloy refractory product and preparation method thereof
The invention discloses a high-toughness ferrosilicon alloy refractory product and a preparation method thereof; raw materials are silicon carbide aggregate and co-grinding powder, a binding agent isadded, co-grinding, wet grinding are carried out and nitriding sintering is carried out at the temperature of 1420 DEG C or below to obtain the high-toughness ferrosilicon alloy refractory product, wherein the co-grinding powder is composed of silicon carbide fine powder and ferrosilicon powder according to the mass ratio of (0.9-1):1. Silicon carbide is used as a main raw material, and the softness of metal is utilized, so that the prepared product has certain toughness, the service life is prolonged, and the product is high in thermal conductivity and non-conductive and can also be used fora cooling wall and a bosh of a blast furnace. And meanwhile, due to the existence of the iron metal phase, the thermal conductivity is further improved.
一种高韧性硅铁合金耐火制品及其制备方法，原始料为碳化硅骨料和共磨粉，外加结合剂，通过共磨、湿碾，在1420℃以下温度氮化烧成而成，其中，共磨粉由质量比为0.9‑1：1的碳化硅细粉和硅铁粉组成。本发明使用了碳化硅为主原料，并利用金属的软性，使制得的制品具有一定的韧性，提高使用寿命，且高导热不导电，还能够用于高炉的冷却壁和炉腹上。同时，由于铁金属相的存在，更加提高了导热性。
