Castable for RH furnace dip pipe
The invention relates to a castable for an RH furnace dip pipe. The castable is mainly composed of the following components in parts by mass: 55-75 parts of waste refractory material powder, 10-15 parts of secondary brown fused alumina, 10-15 parts of urea resin, 2-5 parts of polypropylene fiber, 2-5 parts of silicon oxide micro-powder, 1-3 parts of carbon fiber powder, 2-8 parts of activated aluminum oxide micro-powder, 4-12 parts of zirconium oxide fiber, 2-3 parts of borax and 1-2 parts of a high-temperature-resistant lubricant. The castable provided by the invention is special for the dippipe, can effectively prevent castable cracking caused by iron sheet deformation, and has the advantages of high toughness, good self-leveling performance and the like.
本发明涉及一种RH炉浸渍管用浇注料，主要由以质量份数计的以下成分组成：废弃耐火材料粉末55‑75份、二级棕刚玉10‑15份、脲醛树脂10‑15份、聚丙烯纤维2‑5份、氧化硅微粉2‑5份、碳纤维粉1‑3份、活性氧化铝微粉2‑8份、氧化锆纤维4‑12份、硼砂2‑3份、耐高温润滑剂1‑2份。本发明的浇注料为浸渍管专用，能够有效防止铁片变形造成的浇注料龟裂，具有韧性高、自流平性能好等优点。
