Technical Field
The utility model belongs to the technical field of steel smelting, and particularly relates to a furnace cover device of a mixer furnace with baking and heat preservation functions.
Background
The mixer is an auxiliary steel-making device between a blast furnace and a converter, and is mainly used for adjusting and balancing the supply and demand of molten iron between the blast furnace and the converter and ensuring that the molten iron required by the converter is supplied uninterruptedly. The molten iron is stored in the mixer furnace and the components and the temperature of the molten iron are uniformly mixed, which is very beneficial to converter steelmaking. However, the use process of the mixer furnace has the following problems: firstly, the furnace lining needs to be replaced after being used for 12-24 months, and the newly replaced furnace lining can be used only after being baked to more than 1000 ℃ from normal temperature; secondly, the temperature of the molten iron stored in the mixer furnace is quickly reduced, so that the temperature of the molten iron entering the converter is low.
In the prior art, the blast furnace of the mixer furnace is generally arranged in the mixer furnace, so that flameout easily occurs in the process of drying the furnace by the blast furnace, the quality of a furnace lining is adversely affected, the production time is delayed, and more seriously, explosion is likely to occur due to the fact that the content of coal gas reaches a certain concentration in a hearth after flameout, and hidden dangers such as gas poisoning of surrounding personnel can be caused by the diffusion of the coal gas.
In the prior art, the hot metal of the mixer furnace is kept warm, and the modes of arranging a gas burner on the end wall of the mixer furnace for baking and arranging a furnace cover at a hot metal charging port for reducing the heat radiation loss are generally adopted. The gas burners arranged on the end wall of the metal mixer are easy to be impacted by the steel slag in the hearth and are easy to be blocked; if the iron feeding amount of the mixer is large and the distance between the liquid level of molten iron and the gas burner is low, the gas burner can be damaged; the furnace cover of the metal mixer only plays a role in reducing temperature loss caused by heat radiation of molten iron, the metal mixer cannot be baked for heat preservation, the temperature of the molten iron is improved, and the function is single.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a furnace cover device of a mixer furnace with baking and heat preservation functions, so as to solve the problems.
In order to achieve the purpose, the utility model adopts the technical scheme that:

In order to further realize the utility model, the heat storage box group comprises at least three heat storage boxes, and the heat storage boxes are radially arranged by taking the burner as the center. This structural design can improve the heat preservation effect of bell, reduces calorific loss.
In order to further realize the utility model, the burner is connected with the gas metal hose through threads. This connected mode can guarantee that the nozzle can follow and establish at the bell rotatory and go up and down to satisfy and adjust the different period temperature control of mixer baker and will reach the mixer stove and advance and toast the requirement under the different liquid level height after the iron, the flame height of nozzle can be adjusted along with the lift of heat accumulation be built by contract, can also realize quick assembly disassembly.
In order to further realize the utility model, the heat storage box group is connected with the air metal hose through threads. Make things convenient for heat accumulation case and air metal collapsible tube to dismantle fast.
In order to further realize the utility model, the burner adopts a gas high-speed burner. In order to prevent the flame of the burner from floating and the rigidity is insufficient during baking, the heat almost hardly reaches the bottom of the iron mixing furnace, so that the phenomena of overheating at the upper part and supercooling at the lower part are caused, a gas high-speed burner is selected, the outlet speed of combustion gas reaches more than 100 m/s, and the rapid temperature rise is ensured.
In order to further realize the utility model, the bottom end of the burner is arranged in the metal mixer.
In order to further realize the utility model, the gas regulating valve is arranged at a position close to the gas main pipe.
Compared with the prior art, the utility model has the beneficial effects that:
according to the utility model, the newly built mixer is baked through the high-speed burners arranged on the furnace cover, heat directly reaches the bottom of the mixer, and heat loss is reduced through the furnace cover, so that the heat efficiency is improved. Compared with the traditional mode, the method omits the special procedure and material for manufacturing the furnace baking tube, eliminates the phenomenon of easy flameout in the furnace baking process of the furnace baking tube, and avoids the hidden troubles of causing adverse effect on the quality of the furnace lining, possible explosion, personnel poisoning caused by gas diffusion and the like. The used coal gas is converter coal gas, blast furnace coal gas, coke oven coal gas or the mixed gas of several kinds of coal gas, and the coal gas regulating valve is arranged to facilitate the control of gas ventilation or gas closing during use and the regulation of flame during baking.
After the blast furnace mixer is put into operation, the blast furnace mixer replaces the gas burner arranged on the end wall of the blast furnace mixer to preserve heat of molten iron, omits the process and materials for arranging the gas burner on the end wall of the blast furnace mixer, eliminates the hidden danger of blockage and damage of the gas burner, is efficient and energy-saving, realizes the double functions of furnace baking and molten iron preservation, and is suitable for top-charging blast furnaces of 300 tons, 600 tons, 900 tons and 1300 tons.
