The main influencing factors of ferrosilicon furnace dust collector include: flue gas working condition (composition, temperature, moisture content, dust concentration, dew point value, sulfur content, etc.), dust properties (particle size, dust particle composition, adhesion, wettability, etc.), flue gas speed in the electric field, air leakage rate of dust collector, electrode hypertrophy, electrode operation, etc.

Traditional ferroalloy submerged arc furnaces generally use pre-baked carbon blocks and wide coarse joints to build the furnace lining, and adjust the primary current to control the depth of the electrode inserted into the furnace (that is, the load of the electric furnace). Take the main equipment of a company's 2*25.5MVA submerged arc furnace as an example. Its lining adopts semi-graphite charcoal brick fine-seam masonry technology, but the redness of the furnace bottom appeared three months after the furnace was opened. Through fine furnace anatomy and cause analysis, find out the solution to the problem.

Low-carbon ferrochrome, as a ferrochrome with low carbon content, is an important additive in steelmaking and casting. Usually, our common stainless steel and high-alloy ferritic steel are added with low carbon content in smelting. Carbon ferrochrome is smelted, and it can be said that low-carbon al
