Description

Technical field [0001] The invention relates to a short-flow ferroalloy smelting device. The device includes a radiation reduction furnace, a smelting material conveying system, a hot air conveying system, a fuel conveying system and an exhaust gas recovery system. The upper part of the radiation reduction furnace is provided with a hemispherical furnace roof. A spherical reflecting surface is set in the furnace roof. Background technique [0002] In the prior art, there are high energy consumption and high pollution problems in the iron and steel industry. The waste heat emission loss of the iron and steel industry accounts for about 38.5% of the total energy consumption, and the physical waste heat of various products accounts for 29-39% of the total energy consumption, of which coking waste gas Sensible heat, sensible heat of coke, sensible heat of sintering, sensible heat of sintering flue gas, and sensible heat of blast furnace gas account for a large proportion. The ironmak...
