Abstract
The utility model relates to a stokehold heat preservation covering agent adds device belongs to blast furnace technical field. The hot-metal ladle furnace comprises a heat-preservation covering agent bin, wherein the heat-preservation covering agent bin is arranged above a furnace front platform, a chute is arranged below the furnace front platform, an outlet of the heat-preservation covering agent bin is connected with a chute, the chute is hinged to an outlet of the chute, and a hot-metal ladle is arranged below the chute; and the heat-preservation covering agent in the heat-preservation covering agent bin flows into the chute through the chute, and the chute is controlled to rotate around the hinge point, so that the heat-preservation covering agent is uniformly added to the surface of the molten iron in the molten iron tank. And a valve is arranged on the chute and used for adjusting the flow of the heat-preservation covering agent. The application not only reduces the usage amount of the heat-preservation covering agent, but also saves the cost; but also reduces the heat loss of the molten iron and the labor intensity of the stokehole workers.
Description
Technical Field
The utility model relates to a stokehold heat preservation covering agent adds device belongs to blast furnace technical field.
Background
From blast furnace tapping to converter steelmaking, the residence time of molten iron in the ladle is about 40-120min, and in order to prevent serious heat loss after the blast furnace molten iron ladle is filled with molten iron and prevent the molten iron ladle from smoking, a heat preservation covering agent needs to be added on the surface of the molten iron ladle. At present, the blast furnace stokehold adopts the manual work to all put in the heat preservation covering agent from putting in a hole bag, can lead to so that all put in a position from the heat preservation covering agent of eminence whereabouts, can't cover the hot metal bottle surface comprehensively, not only causes very big waste, and this kind of method heat preservation effect is poor moreover, and calorific loss is big, causes the steelmaking cost to rise, and the jar surface glues the iron slag, and the clearance difficulty still can produce a large amount of smoke and dust, polluted environment.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a stokehold heat preservation covering agent adds device is provided to above-mentioned prior art, not only reduces heat preservation agent use amount and practices thrift the cost, still reduces molten iron calorific loss, reduces the hot metal bottle and smokes, reduces stokehold worker intensity of labour.
The utility model provides a technical scheme that above-mentioned problem adopted does: a stokehole heat-preservation covering agent adding device comprises a heat-preservation covering agent bin, wherein the heat-preservation covering agent bin is arranged above a stokehole platform, a chute is arranged below the stokehole platform, an outlet of the heat-preservation covering agent bin is connected with a chute, the chute is hinged to an outlet of the chute, and a hot metal ladle is arranged below the chute; and the heat-preservation covering agent in the heat-preservation covering agent bin flows into the chute through the chute, and the chute is controlled to rotate around the hinge point, so that the heat-preservation covering agent is uniformly added to the surface of the molten iron in the molten iron tank.
And a valve is arranged on the elephant trunk and used for adjusting the flow of the heat-preservation covering agent.
Compared with the prior art, the utility model has the advantages of: a stokehole heat-preservation covering agent adding device enables heat-preservation covering agents to be uniformly added on the surface of molten iron by controlling the chute to rotate and tilt and adjusting the flow of the heat-preservation covering agents. The application not only reduces the usage amount of the heat-preservation covering agent, but also saves the cost; but also reduces the heat loss of molten iron and the labor intensity of stokehole workers.
Drawings
FIG. 1 is a schematic view of a stokehole heat-insulating covering agent adding device according to an embodiment of the present invention;
in the figure, 1 a heat-preservation covering agent bin, 2 a chute, 3 a stokehold platform, 4 a chute and 5 a hot metal ladle.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the stokehole heat-insulating covering agent adding device in the present embodiment includes a heat-insulating covering agent bin 1, the heat-insulating covering agent bin 1 is disposed above a stokehole platform 3, and a chute 4 is disposed below the stokehole platform 3. The outlet of the heat-preservation covering agent bin 1 is connected with the chute 2 which is vertically arranged, the chute 4 is hinged to the outlet of the chute 2, and the cylinder drives the chute 4 to rotate around the hinged point, so that the inclination angle of the chute 4 is changed. A hot metal ladle 5 filled with hot metal is arranged below the chute 4. The heat preservation covering agent in the heat preservation covering agent bin 1 flows to the chute 4 through the chute 2, the chute 4 rotates around a hinged point, and the inclination angle of the chute 4 is adjusted, so that the heat preservation covering agent is uniformly added to the surface of molten iron in the molten iron tank 5.
The chute 2 is provided with a valve for adjusting the flow of the heat preservation covering agent.
When the hot metal tank is full of hot metal and the heat-preservation covering agent needs to be added, a stokehold worker controls the feeding control system to enable the heat-preservation covering agent to be added to the chute through the heat-preservation agent covering bin along the chute, and the heat-preservation covering agent is uniformly added to the surface of the hot metal by controlling the chute to rotate and tilt and adjusting the flow of the heat-preservation covering agent. The application not only reduces the usage amount of the heat-preservation covering agent, but also saves the cost; but also reduces the heat loss of the molten iron and the labor intensity of the stokehole workers.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
