Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to hot charging and hot conveying equipment for a large silicon-manganese ore hot furnace. Background Art

[0002] Silicon manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. It is a ferroalloy with a wide range of uses and a large output. Silicon manganese alloys are refined and produced by using carbon to simultaneously reduce manganese oxide and silicon dioxide in manganese ore and silica in a submerged arc furnace. Silicon manganese alloy is mainly used as an intermediate material for deoxidizer and alloying agent in steel production, and is also the main raw material for the production of medium and low carbon ferromanganese. During the smelting process of silicon manganese ore in a hot furnace, hot charging and hot delivery equipment is needed to feed the heated raw materials into the submerged arc furnace to reduce the heat consumption of the submerged arc furnace itself and improve the reaction efficiency and stability. Existing hot charging and insulation devices are mostly box structures composed of multiple layers of insulation materials, which can only play a role in insulation. The raw materials need to be manually taken and placed in turn, and heat is easily lost in this process, affecting the smelting efficiency. Some rollers are used to assist in loading and unloading, but they still need to be manually clamped and extended into the box, which is not convenient enough, and the raw materials are prone to rolling down the edges to the outside when unloading.
