Submerged arc furnace equipment for producing macrocrystalline fused magnesite

Abstract

The invention provides submerged arc furnace equipment for producing macrocrystalline fused magnesite. The submerged arc furnace equipment for producing the macrocrystalline fused magnesite comprisesa submerged arc furnace cylinder, a furnace cover system, a material input system, a broken electrode conveying system and a dust removal and material return system, the furnace cover system is arranged at an upper opening of the submerged arc furnace cylinder, and the material input system and the broken electrode conveying system are arranged on the furnace cover system. The furnace cover systemis provided with a dust removal pipeline, the dust removal pipeline is connected with a dust removal and material return system, and the dust removal and material return system can collect coarse particles in dust and timely return the coarse particles into a submerged arc furnace to be used again. According to the submerged arc furnace equipment for producing the macrocrystalline fused magnesite, by reasonably designing the systems, the systems are organically combined and matched, so that the production efficiency of the submerged arc furnace is improved, an environment-friendly productionenvironment is realized, the labor intensity of workers is reduced, accidents are effectively prevented, automatic treatment is realized, and the production cost of a manufacturer is reduced.

Description

technical field [0001] The invention relates to the field of manufacturing large-crystal fused magnesia, in particular to submerged arc furnace equipment for producing large-crystal fused magnesia. Background technique [0002] Large crystalline fused magnesia is mainly produced by melting light-burned magnesia powder in a submerged arc furnace. It has many advantages such as high purity, large crystal grains, compact structure, strong slag resistance, and good thermal shock stability. It is a high-grade It is an important raw material for the production of magnesia bricks, magnesia-carbon bricks and unshaped refractory materials. [0003] Three graphite electrodes are placed inside the submerged arc furnace, and the three graphite electrodes are respectively located at the corners of the triangle. A layer of crushed electrodes is added between the graphite electrodes to start the furnace and arc, and heat and melt the charge between the electrodes. During the production pr...
