Internal-combustion high temperature furnace for ferro-coke pellets/lump ores

Abstract

The invention provides an internal-combustion high temperature furnace for ferro-coke pellets / lump ores, which is characterized in that: the high temperature furnace comprises a high temperature furnace body; the front end and the rear end of the high temperature furnace body are provided with a pre-heating furnace and a cooling system respectively; the rear end of the cooling system is provided with a discharging platform; the front end of the pre-heating furnace is provided with an upper loading platform and a lower loading platform positioned below the upper loading platform; the ends of the upper loading platform and the lower loading platform are provided with a vehicle pusher respectively; and the upper loading platform and the lower loading platform are connected with the discharging platform by running through the pre-heating furnace, the high temperature furnace body and a sliding guide rail for a charging carriage of the cooling system respectively. The internal-combustion high temperature furnace has the advantages of simple structure, rational heating, uniform furnace temperature, high heat efficiency and capability of effectively controlling the emission of harmful gas, low labour intensity and production cost reduction.

Description

technical field [0001] The invention relates to an internal combustion type iron coke pellet / lump ore high-temperature furnace, which belongs to the technical field of manufacturing equipment for smelting pellet / lump ore. Background technique [0002] The iron concentrate is oxidized and sintered into sinter or pellets before ironmaking in traditional blast furnaces. Generally, tunnel-type sintering furnaces or shaft-type roasting furnaces are used for roasting with open flames. Tunnel-type sintering furnace includes batching, mixing, distribution, and then sintering and product treatment. The disadvantages are that the production process and time are long, consume a lot of fuel, emit large amounts of harmful smoke, cause serious environmental pollution, and require large equipment investment and high cost. . The vertical roaster also has long processing time, low output, high energy consumption, a large amount of sulfur dioxide and carbon dioxide emissions, pollutes the en...

Problems solved by technology

Tunnel-type sintering furnace includes batching, mixing, distribution, and then sintering and product treatment. The disadvantages are that the production process and time are long, consume a lot of fuel, emit large amounts of harmful smoke, cause serious environmental pollution, and require large equipment investment and high cost.

The vertical roaster also has long processing time, low output, high energy consumption, a large amount of sulfur dioxide and carbon dioxide emissions, pollutes the environment, and a large amount of unformed tailings, which increases production costs
