Technical Field

[0001] The utility model relates to the technical field of submerged arc furnace unloading, in particular to a submerged arc furnace unloading mechanism for high-titanium slag production. Background Art

[0002] Submerged arc furnace, also known as electric arc furnace, relies on the resistance heat generated by electric arc and current passing through the charge to heat and melt, and uses carbon as a reducing agent to reduce and smelt metal ores. It is mainly used to produce ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon-manganese alloy and other ferroalloys. It is an important equipment commonly used in the metallurgical industry. When smelting in a submerged arc furnace, the raw materials in the silo need to be added from the top of the submerged arc furnace to the furnace through the feed pipe.

[0003] When adding materials to an electric arc furnace, a large amount of high-titanium slag is generally added at the same time. This situation easily causes the accumulation of high-titanium slag, resulting in uneven heating of the electric arc furnace. In addition, the high-titanium slag in the silo is of different sizes. Therefore, when processing in an electric arc furnace, the reaction heating time is determined by the high-titanium slag with larger particles. The total processing time is longer and the efficiency is lower. Utility Model Content
