Vertical heat exchange type alloy baking oven system

Abstract

The invention discloses a vertical heat exchange type alloy baking oven system which comprises a baking oven, hoppers and flatcars. Two tracks are parallelly arranged inside the baking oven, a plurality of burning nozzles are installed at the oven top of the baking oven, an air channel communicated with the baking oven is arranged under the baking oven, an induced air pipes are parallelly arranged in the air channel, and a plurality of air outlets are formed in the flatcars and are mutually communicated with the induced air pipes. The vertical heat exchange type alloy baking oven system remarkably improves the heat exchange efficiency, the temperature of baked alloy is uniform, and the baking effect is remarkable. In addition, the baking time is short, the gas and electric energy consumption is low and operation cost is low in the whole baking process, and the vertical heat exchange type alloy baking oven system has the advantages of being low in investment, reasonable in process and easy to operate, can well solve the problem of high achievement costs of lots of iron and steel enterprises at present and the problems of an efficient iron alloy baking process, produces better economic benefits and is easy to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of converter steelmaking equipment, and in particular relates to a vertical heat exchange type alloy baking furnace system. Background technique [0002] Alloy is an important raw material for steelmaking. The moisture content in the alloy directly affects the quality of molten steel and the tapping temperature. Therefore, the alloy material needs to be baked before it can be used. The role of alloy baking is to remove moisture. Reducing the hydrogen content of the steel type water, on the other hand, can reduce the cooling of molten steel during the process of adding molten steel and avoid increasing energy consumption. Therefore, the alloy baking process is very commonly used in the smelting process of steel. At present, most steelmaking enterprises use alloy baking furnaces for alloy baking. The working principle of alloy baking furnaces is that, according to actual production conditions, a certain temper...

AI Technical Summary

Problems solved by technology

The above-mentioned alloy baking furnace system is found in the actual use process, because the high-temperature gas enters the furnace from both sides of the furnace for heating, relying on the airflow on both sides to heat the alloy raw material, when the density of the alloy raw material is high , the high-temperature gas flow is inhibited by the alloy raw material, and the alloy cannot be completely or unable to be heated, so that the alloy raw material and the high-temperature gas cannot perform heat exchange normally, the high-temperature flue gas cannot flow, the temperature distribution is uneven, and the heat transfer efficiency is low. Baking The effect is not ideal, and in order to achieve the baking temperature of the alloy, a large amount of high-temperature gas needs to be introduced, which invisibly causes a lot of waste of gas and electric energy, which is unreasonable in terms of technology and economy.
