High-temperature-resistant and corrosion-resistant smelting furnace lining material and preparation process thereof
The invention discloses a high-temperature-resistant and corrosion-resistant smelting furnace lining material which is prepared from the following raw materials in percentage by weight: 55-60% of fused magnesite coarse particles, 30-35% of fused magnesite fine particles, 2-3% of crystalline flake graphite, 0.5-0.9% of nano carbon black, 1-2% of phenolic resin doped with transition metal elements and 1-3% of Al2O3-SiC powder, the transition metal element comprises at least one of Ti, Co, Ni, Fe or Cr. The performance of the smelting furnace lining material is superior to that of a furnace lining material which singly adopts crystalline flake graphite as a carbon source, the corrosion resistance and permeability of the smelting furnace lining material to oxidizing slag can be improved, and the oxidation resistance of the smelting furnace lining material is also improved to a certain extent.
本发明公开一种耐高温耐腐蚀的冶炼炉衬材料，由以下重量百分含量的原料制成：电熔镁砂粗颗粒55‑60％、电熔镁砂细颗粒30‑35％、鳞片石墨2‑3％、纳米炭黑0.5‑0.9％、掺杂有过渡金属元素的酚醛树脂1‑2％和Al2O3‑SiC粉体1‑3％,过渡金属元素包括Ti、Co、Ni、Fe或Cr中的至少一种。本发明的冶炼炉衬材料性能优于单独采用鳞片石墨为碳源的炉衬材料，能提高低炉衬材料对氧化性熔渣的抗侵蚀和渗透性能,对其抗氧化性能也有一定程度的改善。
