Description

Technical Field

[0001] The utility model relates to the technical field of fused magnesia production equipment, in particular to a fused magnesia furnace. Background Art

[0002] Fused magnesia is made from natural magnesite or high-purity light-burned magnesium particles or concentrate powder purified by flotation of low-grade magnesite, and is smelted in a three-phase electric arc furnace.

[0003] For example, in the utility model patent with announcement number CN220418042U, an electric molten magnesia smelting equipment is disclosed. In view of the fact that the existing electric arc furnace does not have a reminder function when pouring materials, uninformed staff are easy to get close and cause burns, the following scheme is now proposed, which includes a U-shaped seat, and rotating columns are rotatably installed on the inner walls of both sides of the U-shaped seat, and one end of the two rotating columns is fixedly installed with the same furnace body, and a furnace cover is installed on the top of the furnace body. A plurality of electrodes are installed on the furnace cover, and the bottom ends of the electrodes extend into the furnace body.

A horizontal plate is fixedly installed on one side of the U-shaped seat, and an L-shaped plate is fixedly installed on the top of the horizontal plate. The utility model is convenient for pouring out the smelted material. When pouring out, the lifting plate can drive the striking block to continuously strike the metal plate, making a sound, which can play a reminder role;

[0004] However, the utility model needs to turn over the furnace body when unloading, and needs to be reloaded after unloading, which greatly reduces the efficiency of the furnace. Therefore, it is a technical problem that technical personnel in this field urgently need to solve to provide an electric fused magnesia furnace that is easy to load and unload.
