Preparation method of environment-friendly ladle castable
The invention provides a preparation method of an environment-friendly ladle castable, and relates to the technical field of refractory materials. The preparation method of the environment-friendly ladle castable comprises the following steps: preparing aluminum silicon carbide carbon brick waste refractory, cleaning to remove impurities, crushing and screening, and removing iron by a magnet rod to obtain a raw material A; performing wheel milling on the raw material A to remove false particles and performing gravity screening to obtain a raw material B; preparing titanium-iron slag, vanadium-iron slag and reduced aluminum-chromium slag, and granulating by using a granulator; airing the particles to be half-dry, drying and cooling to obtain respective slag particles; heating and stirring the raw material B and the thermosetting phenolic resin, and sequentially adding the slag particles of the raw material B, the thermosetting phenolic resin and the slag particles to obtain the pretreated castable. According to the invention, the waste refractory material is reused in the preparation of the refractory material, so that the raw materials are reused, the resources are saved, the production cost is reduced, the environment-friendly preparation method is adopted, the environmental pollution is reduced, and the furnace slag is utilized to reinforce and improve partial performance of the iron ladle castable.
本发明提供一种环保型铁包浇注料的制备方法，涉及耐火材料技术领域。该环保型铁包浇注料的制备方法，包括以下步骤：准备铝碳化硅碳砖废旧耐材，清洗去除杂质，破碎筛选，磁铁棒去铁，即得到原料A；原料A轮碾去除假颗粒和重力筛分，得到原料B；准备钛铁渣、钒铁渣和还原铝铬渣，颗粒机制成颗粒；颗粒晾半干，干燥冷却，得到各自的炉渣颗粒；原料B和热固酚醛树脂加热搅拌，依次投入三者的炉渣颗粒，得到预处理浇注料。通过利用废旧耐火材料，将其重新应用到耐火材料的制备中，使其原料得到重复的利用，节约资源，降低生产成本，同时采用环保型的制备方法，降低环境污染，其次，利用炉渣加强和提高铁包浇注料的部分性能。
