Ladle slag line magnesia carbon brick produced by using waste magnesia carbon brick and preparation method thereof
The invention discloses a ladle slag line magnesia carbon brick produced from waste magnesia carbon bricks and a preparation method of the ladle slag line magnesia carbon brick, and relates to the technical field of magnesia-calcium bricks. Comprising the following raw materials in parts by weight: 15-45 parts of fused magnesite with the particle size of 1-5mm, 2-12 parts of macrocrystalline fused magnesite with the particle size of 0.074-1mm, 15-50 parts of a waste magnesia carbon brick reclaimed material with the particle size of 0-5mm, 9-13 parts of graphite with the particle size of 80-100 meshes, 0.5-3 parts of superfine graphite with the particle size of 800-1000 meshes, 0.5-3 parts of magnesium shield with the particle size of 0-1mm, 12-18 parts of mixed powder, 2-4 parts of a binding agent and 0.01-0.1 part of an additive. By adjusting the composition of the raw materials and the addition amount of the reclaimed material and adding a certain amount of magnesium shield, superfine graphite, resin admixture and mixed powder, air holes caused by addition of the reclaimed material are reduced, the slag adhering performance is improved, the steel slag erosion speed of the slag line magnesia carbon brick is reduced, and the steel ladle slag line brick with good performance is obtained while the reclaimed material is utilized to the maximum extent.
本发明公开一种用废镁碳砖生产的钢包渣线镁碳砖及其制备方法，涉及镁钙砖技术领域，包括如下重量份的原料：15～45份粒度为1‑5mm的电熔镁砂、2～12份粒度为0.074‑1mm的大结晶电熔镁砂、15～50份粒度为0‑5mm的废镁碳砖再生料、9～13份粒度为80‑100目的石墨、0.5～3份粒度为800‑1000目的超细石墨、0.5～3份粒度为0‑1mm的镁盾、12～18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，加入一定量的镁盾、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，提高挂渣性能，降低渣线镁碳砖钢渣侵蚀速度，旨在最大程度利用再生料的同时获得性能良好的钢包渣线砖。
