Dry material environment-friendly binding agent for continuous casting tundish
The invention relates to the field of binding agents, and provides a continuous casting tundish dry material environment-friendly binding agent which comprises the following raw materials: 0.1-0.5% of ether polycarboxylic acid ester, 20% of alumina micro powder, 3-6% of low-iron calcium aluminate cement, 0.1-0.5% of silicon dioxide, 1-5% of calcium oxide and 0.1-0.5% of calcium phosphate. When being used as a binding agent of a tundish dry material, the high-temperature-resistant binding agent not only reduces recarburization and hydrogen increase of molten steel, but also meets the requirement for smelting steel with low carbon content, does not generate pungent smells such as cresol and formaldehyde when being used at high temperature, and is free of pollution to the environment; compared with the prior art, the method has the advantages that the method is simple in process, good in corrosion resistance and easy to disintegrate, bonding strength and medium-temperature strength both meet demolding requirements, the problem that breaking strength and compression strength of dry materials are reduced during medium-temperature online baking is effectively avoided, breaking strength and compression strength after heat treatment are both remarkably improved, and the problem that lining strength is low after a glucose binding agent is demolded is effectively solved.
本发明涉及结合剂领域，提供一种连铸中间包干式料环保型结合剂，其原料组成为：醚基聚羧酸脂0.1‑0.5％，氧化铝微粉20％，低铁型铝酸钙水泥3‑6％，二氧化硅0.1‑0.5％，氧化钙1‑5％，磷酸钙0.1‑0.5％；本发明作为中间包干式料的结合剂时，不仅减少给钢水的增碳增氢，且满足冶炼碳含量较低的钢种需求，高温使用时不产生甲酚、甲醛等刺激性气味，对环境无污染；抗侵蚀性能良好、容易解体、结合强度和中温强度均满足脱模要求，有效避免了干式料中温在线烘烤时抗折强度和耐压强度下降的问题，热处理后的抗折强度、耐压强度均显著提高，有效解决了葡萄糖结合剂脱模后衬体强度偏低的问题。
