Water cooling framework of inner ring of furnace cover of silicon iron furnace

Abstract

The invention provides a water cooling framework of an inner ring of a furnace cover of a silicon iron furnace. The furnace cover of the silicon iron furnace comprises an inner ring and an outer ring,wherein the water cooling framework is welded in the inner ring, the water cooling framework is in a three-fork shape, an intersection point of the three-fork coincides with a circle center of the inner ring, and three supporting points of the water cooling framework are welded to the wall of the inner ring. According to the water cooling framework of the inner ring of the furnace cover of the silicon iron furnace, the service life is prolonged, a previous square pipeline is changed into a round stainless steel pipeline, so that the flowing state of circulating water in the pipeline is reduced when the circulating water enters the pipeline, and the phenomenon that the pipeline is corroded by adhesives generated at a high temperature is avoided; and the water cooling framework of the innerring of the furnace cover of the silicon iron furnace is formed by splicing the stainless steel pipes, so that weld joints of the pipeline formed by welding stainless steel plates are reduced, and the phenomenon that the production is affected due to furnace shutdown caused by weld cracking and water leakage is greatly avoided.

Description

technical field [0001] The invention belongs to the field of smelting equipment, and in particular relates to a water cooling structure of a ferrosilicon furnace. Background technique [0002] Ferrosilicon is an essential deoxidizer in the steelmaking industry, and it is also used as an alloy additive. It is widely used in the field of metallurgy. Using silica, steel, and coke as raw materials, ferrosilicon alloys are formed after high-temperature reduction at 1500-1800 degrees. The electric furnace used to smelt iron-silicon alloys is called ferrosilicon furnace. The circulating cooling water of the ferrosilicon furnace is supplied by the circulating water pump station. After entering the electric furnace cooling equipment, the cooling water naturally flows back to the cooling pool by using the drop. After natural cooling in the pool, the water is supplied to the front of the furnace by a pump. The cooling water of the entire electric furnace is an open circuit cycle. . ...

AI Technical Summary

Problems solved by technology

During the long-term actual use, it was found that since the pipes spliced ​​into the water-cooled skeleton are square pipes with many welds, the water-cooled skeleton will often be damaged due to scaling in the pipes and thermal ablation of the welds. It is time-consuming and labor-intensive to make the skeleton, which greatly affects the normal ferrosilicon production
