Process for smelting brown aluminum oxide through high-pressure dry powder ball pressing technology
The invention provides a process for smelting brown aluminum oxide through a high-pressure dry powder ball pressing technology. The process comprises the steps that S1, raw materials are prepared, wherein the raw materials are proportioned according to a certain proportion and fully mixed according to test results of raw material components and production requirements; s2, crushing: crushing the mixed raw material obtained in S1 into fine particles by using a Raymond mill; s3, ball pressing: pressing the raw materials crushed in S2 into pellets by using a high-pressure dry powder ball press; and S4, smelting, wherein the pressed raw material balls are directly put into an electric arc furnace to be smelted, and the operation instruction and method are kept unchanged compared with the prior art. The process comprises the following steps: mixing and crushing the raw materials according to a certain proportion according to production requirements, carrying out high-pressure dry powder ball pressing, and finally feeding into an electric arc furnace for smelting. A certain amount of water and a certain amount of a binder do not need to be added into the raw materials, furnace spraying accidents are avoided, raw material particles are fine, various components are evenly distributed, the reaction speed is high during smelting, and energy consumption and smelting time are remarkably reduced.
本发明提供一种高压干粉压球技术冶炼棕刚玉的工艺，该工艺包括：S1、原料制备：根据原料成分化验结果和生产要求按一定比例配比原料并充分混合；S2、粉碎：将S1得到的混合原料利用雷蒙磨粉碎为细颗粒；S3、压球：将S2粉碎后的原料用高压干粉压球机压制为球粒；S4、冶炼：压制好的原料球直接投入电弧炉中进行冶炼，操作规程和方法与现在技术保持不变。本发明将原料按生产要求以一定比例混合粉碎，进行高压干粉压球，最后送入电弧炉中进行冶炼的工艺。原料中无须加入一定量的水和粘结剂，避免了“喷炉”事故发生，原料颗粒细小，各种成分分布均匀，冶炼时反应速度快，显著降低了能耗和冶炼时间。
