Environment-friendly refractory kiln furniture and preparation method thereof
The invention relates to environment-friendly refractory kiln furniture, which is prepared from the following raw materials: waste corundum bricks, waste cordierite-mullite kiln furniture clinker, Dehua kaolin, bauxite, dolomite, Dehua sericite and industrial alpha-alumina powder. According to the refractory kiln furniture prepared by the invention, waste corundum bricks, waste cordierite-mullite kiln furniture clinker, Dehua kaolin, bauxite, dolomite, Dehua sericite and industrial alpha-alumina powder are used as matrix materials to form a solid of the refractory kiln furniture material, the components of the raw materials are specifically limited to strictly control the chemical components of the raw materials, so that the prepared refractory kiln furniture is high in breaking strength at normal temperature, the refractoriness under load of 0.2 MPa can reach 1420 DEG C, the highest use temperature of the refractory kiln furniture is increased, the refractory kiln furniture is suitable for kilns with higher temperature requirements, and the practicability of the kiln furniture is improved; and the utilization rate of the waste corundum bricks reaches more than 30%, the waste of resources is reduced, and the production cost of kiln furniture materials is also reduced.
一种环保型耐火窑具,由以下原料组成:废旧刚玉砖、废旧堇青石‑莫来石窑具熟料、德化高岭土、铝矾土、白云石、德化绢云母、工业α‑氧化铝粉,本发明制备的耐火窑具以废旧刚玉砖、废旧堇青石‑莫来石窑具熟料、德化高岭土、铝矾土、白云石、德化绢云母、工业α‑氧化铝粉为基质材料组成本发明耐火窑具材料的固体物,并具体限定各原料的组分以对原料的化学组分进行严格的把控,使制得的耐火窑具常温抗折强度高、0.2MPa荷重软化温度可达到1420℃,提高耐火窑具的最高使用温度,以适用温度要求更高的窑炉,提高窑具的实用性;并且对废旧刚玉砖的利用率达到30%以上,减少了对资源的浪费,也降低了窑具材料的生产成本。
