Description
Technical Field
The utility model relates to a field is smelted to the aluminothermic process, especially relates to ferrotitanium and smelts technical field, and specifically speaking is a smelting controlgear who adopts when ferrotitanium is smelted.
Background
The traditional ferrotitanium is mostly prepared from rutile and titanium concentrate as raw materials by an aluminothermic method and an electro-aluminothermic method. When the ferrotitanium is produced by using the aluminothermic method, the aluminum powder for reduction is the main material for smelting, and the granularity of the materials for production reaction is about 80 meshes. A large amount of smoke and dust are generated in the reaction during smelting and must be collected by an environment-friendly device, a dust hood is arranged on the reaction furnace during collection, and a feeding port during smelting is tightly attached to the dust hood. When smelting and feeding materials, more added reaction materials are sucked by a fan, particularly, aluminum powder with fine particles has light specific gravity and fine particle size, and brings loss to the reaction effect.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problems in the prior art and providing a smelting control device which is adopted when ferrotitanium is smelted.
The utility model aims at solving through the following technical scheme:
the utility model provides a smelt controlgear, is including setting up suction hood and corresponding tobacco pipe in smelting furnace top, its characterized in that: the dust hood in be equipped with the crossbeam, be equipped with the baffle of hanging in the smelting furnace top below the crossbeam, the baffle hangs on the crossbeam through the chain.
The cross beam is internally provided with a rotating shaft for fixing the chain, one end of the rotating shaft is connected to the driving end of the motor, and the motor drives the rotating shaft to rotate so as to regulate and control the hanging height of the baffle.
The motor is positioned on the outer side of the dust hood.
The beam is internally provided with a rotating seat for supporting the rotating shaft.
The baffle is positioned above the discharge hole of the feeding chute.
Compared with the prior art, the utility model has the following advantages:
the utility model utilizes the space in the smoke absorption hood on the smelting furnace to increase a baffle plate to change the flow direction of the wind speed during smoking, so that the smoke dust and the fine materials do not directly flow away and can participate in the reaction, and only the smoke dust after the reaction is upwards absorbed from the periphery of the baffle plate; and the baffle is located the top of the discharge gate of feeding chute, avoids the reaction material of adding to be absorbed by the fan.
The smelting control equipment of the utility model can reduce the aluminum distribution coefficient under the condition of not changing raw materials, the reaction heat is not changed, and the production process is safe and reliable; the prepared ferrotitanium series products have stable quality, high titanium grade, low sulfur and phosphorus level and moderate aluminum-silicon content, and completely meet the technical quality requirements of modern steel industry on ferrotitanium.

Wherein: 1-smelting furnace; 2-a dust hood; 3, a smoke pipe; 4, a cross beam; 5, a baffle plate; 6, a chain; 7-a rotating shaft; 8, a motor; 9-a rotating base; 10-feeding chute.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1: a smelting control device comprises a dust hood 2 arranged above a smelting furnace 1 and corresponding smoke pipes 3, wherein a cross beam 4 is arranged in the dust hood 2, a baffle plate 5 suspended above the smelting furnace 1 is arranged below the cross beam 4, and the baffle plate 5 is suspended on the cross beam 4 through a chain 6; the baffle 5 is used for changing the flow direction of the air speed during smoking, so that the smoke dust and the fine materials do not directly flow away and can participate in the reaction, and only the smoke dust after the reaction is upwards sucked away from the periphery of the baffle 5.
In order to adjust the hanging height of the baffle 5, a rotating shaft 7 for fixing the chain 6 is arranged in the beam 4, a rotating seat 9 for supporting the rotating shaft 7 is arranged in the beam 4, one end of the rotating shaft 7 is connected to the driving end of a motor 8, and the motor 8 is positioned on the outer side of the dust hood 2; the suspension height of the baffle 5 is adjusted and controlled by the rotation of the rotating shaft 7 driven by the motor 8.
In addition, the baffle 5 is positioned above the discharge hole of the charging chute 10, so that the added reaction materials are blocked by the baffle 5 and fall into the smelting furnace 1 to participate in reaction during smelting charging.
The utility model utilizes the space in the smoke absorption hood 2 on the smelting furnace 1 to increase a baffle 5 to change the flow direction of the wind speed during smoking, so that the smoke dust and the fine materials do not directly flow away and can participate in the reaction, and only the smoke dust after the reaction is upwards absorbed from the periphery of the baffle 5; and the baffle 5 is positioned above the discharge hole of the feeding chute 10, so that the added reaction materials are prevented from being sucked by a fan. The smelting control equipment can reduce the aluminum distribution coefficient under the condition of not changing raw materials, the reaction heat is not changed, and the production process is safe and reliable; the prepared ferrotitanium series products have stable quality, high titanium grade, low sulfur and phosphorus level and moderate aluminum-silicon content, and completely meet the technical quality requirements of modern steel industry on ferrotitanium.
The above embodiments are only for explaining the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby, and any modification made on the basis of the technical scheme according to the technical idea provided by the present invention all fall within the protection scope of the present invention; the technology not related to the utility model can be realized by the prior art.
