Steel ladle alumina-magnesia carbon brick produced by using waste alumina-magnesia carbon brick and preparation method of steel ladle alumina-magnesia carbon brick
The invention relates to a steel ladle alumina-magnesia carbon brick produced from waste alumina-magnesia carbon bricks and a preparation method of the steel ladle alumina-magnesia carbon brick, and relates to the technical field of steel ladle alumina-magnesia carbon brick processing. Comprising the following raw materials in parts by weight: 25-55 parts of brown fused alumina with the particle size of 0.074-5mm, 15-45 parts of a waste alumina-magnesia carbon brick reworked material with the particle size of 1-5mm, 3-5 parts of graphite with the particle size of 80-100 meshes, 0.5-2 parts of superfine graphite with the particle size of 800-1000 meshes, 1-3 parts of fused spinel fine powder with the particle size of 325 meshes, 9-11 parts of white corundum fine powder with the particle size of 325 meshes, 3-14 parts of mixed powder, 2-4 parts of a binding agent and 0.01-0.1 part of an additive. According to the invention, by adjusting the composition of the raw materials and the addition amount of the reclaimed material, and adding a certain amount of superfine graphite, resin admixture and mixed powder, slag permeation channels such as pores caused by the addition of the reclaimed material are reduced, and the erosion resistance and stripping resistance of the ladle alumina-magnesia carbon brick are improved.
本发明涉及一种用废铝镁碳砖生产的钢包铝镁碳砖及其制备方法，涉及钢包铝镁碳砖加工技术领域，包括如下重量份的原料：25～55份粒度为0.074‑5mm的棕刚玉、15～45份粒度为1‑5mm的废铝镁碳砖再生料、3～5份粒度为80‑100目的石墨、0.5～2份粒度为800‑1000目的超细石墨、1～3份粒度为325目的电熔尖晶石细粉、9～11份粒度为325目的白刚玉细粉、3～14份的混合粉、2～4份的结合剂、0.01～0.1份的外加剂。本发明通过调整原料组成及再生料加入量，加入一定量的超细石墨、树脂外加剂以及混合粉，减少因再生料加入导致的气孔等熔渣渗透通道，提高钢包铝镁碳砖抗侵蚀、抗剥落性能。
