Process for preparing special silicon carbide castable for incinerator
The invention discloses a process for preparing a special silicon carbide castable for an incinerator. The process comprises the following steps: S1, selecting materials: silicon powder, graphite powder and an inorganic adhesive; s2, mixing the raw materials: selecting high-purity silicon powder and graphite powder as raw materials, and screening and mixing the raw materials; s3, adding a binder: adding a proper amount of an inorganic binder into the mixed raw materials, and uniformly stirring to obtain a forming material; s4, forming: performing compression forming on the formed material, wherein an extrusion or compression forming mode is generally adopted; s5, drying: drying the formed material to remove moisture and organic matters in the material; the use amount of the graphite powder is increased, a special forming process is adopted, after forming, low-temperature drying and carbonization are performed, cracks of the product are effectively avoided, and the strength and heat resistance of the material can be improved through holding of the inert atmosphere.
本发明公开了一种制备焚烧炉专用碳化硅浇注料的工艺，包括如下步骤：S1材料的选取：硅粉、石墨粉和无机粘接剂；S2原材料的混合：选用高纯度的硅粉和石墨粉作为原材料，并进行筛分和混合；S3添加粘结剂：将适量的无机粘结剂加入混合好的原材料中，搅拌均匀得到成型材料；S4成型：将成型材料压制成形，通常采用挤出或压缩成型的方式；S5烘干：将成型后的材料进行烘干，以去除其中的水分和有机物；本发明增加石墨粉的用量，采用特殊成型工艺，在成型后，进行低温烘干后，再进行碳化，有效避免产品产生裂缝，并通过惰性气氛的加持，可以提高材料的强度和耐热性。
