Abstract
The utility model discloses a roaster for a steel teeming ladle. The steel teeming ladle comprises a ladle body and a ladle cover (6), and the roaster mounted on the ladle cover (6) comprises a hoist (1), a support arm (2), an air pipe (3), a high-pressure fan (5), a high-speed temperature regulating burner (7) and an oil pipe (8). The high-speed temperature regulating burner (7) is mounted exactly in the middle of the ladle cover (6); the air pipe (3) and the oil pipe (8) are connected onto the high-speed temperature regulating burner (7); the air pipe (3) is connected with the high-pressure fan (5) through a regulating valve (4); the oil pipe (8) is connected with an oil pump through a regulating valve; the ladle cover (6) is connected to one end of the support arm (2); the other end of the support arm (2) is connected with a pulley; and the pulley is connected with the hoist (1) through a steel wire rope. The roaster is simple in structure, convenient in operation and capable of effectively reducing the temperature difference between the steel teeming ladle and molten steel, reducing tapping temperature, prolonging the service life of a furnace, increasing steel yield and reducing raw material consumption and cost of per ton of steel.
Description
Technical field
The utility model relates to the electric furnace tooling device, is specifically related to a kind of ladle roaster.
Background technology
As everyone knows, it is one of important step in the STEELMAKING PRODUCTION operation that the various ladles of new block, cold repair, drying, turnover and online production are toasted, and baking all has very big influence to tapping temperature, steel-making operating rate, furnace life etc.The ladle baking is between making steel and pouring into a mould between two main production processes, and the height of ladle baking temperature plays an important role to coordinating integral production, and the meaning that continuous pouring is produced is more great.
The heat-energy losses of molten steel is very big the molten steel running from steel making working procedure to the cast operation, wherein ladle accumulation of heat loss accounts for about half of molten steel heat-energy losses, the temperature when if the heat-energy losses that does not adopt ladle to toast to compensate molten steel guarantees pouring molten steel, certainly will will improve the tapping temperature of molten steel, but this can bring a series of problem.At first to improve tapping temperature, will increase the duration of heat, increase raw materials consumption, improve ton steel cost; Secondly, lining wear is speeded up, reduced furnace life.Therefore, improve the baking temperature of ladle, to reduce tapping temperature, improve body of heater life-span, increase output of steel, reduce raw materials consumption, reduce ton steel cost, guarantee all having great importance smoothly of continuous pouring.
Summary of the invention
The purpose of this utility model is: a kind of ladle roaster is provided, and this roaster is simple in structure, and is easy to operate, and programming rate is fast, and burner kinetic energy is big, and flame is long, the temperature height, and the burner life-span is long.
Technical solution of the present utility model is: ladle is made up of staving and bung, roaster is installed on bung, described roaster comprises hoist engine, support arm, airduct, high pressure positive blower, high velocity temperature adjusting burner and oil pipe, high velocity temperature adjusting burner is installed in middle at bung, connect airduct and oil pipe on the high velocity temperature adjusting burner, airduct connects high pressure positive blower through control valve, oil pipe connects oil pump through control valve, bung connects an end of support arm, the other end of support arm connects pulley, and pulley connects hoist engine through steel wire rope.
During work, after being extracted out by oil pump, fuel enters the high velocity temperature adjusting burner of roaster, combustion air enters high velocity temperature adjusting burner by high pressure positive blower through airduct, fuel mixes, finishes burning with combustion air at high velocity temperature adjusting burner, the hot flame gas that produces is sprayed by high velocity temperature adjusting burner, and high velocity temperature adjusting burner sprays hot flame gas speed greater than 100 meter per seconds, 200-1400 ℃ of outlet temperature adjustable range, strengthen gas circulation in the ladle, improve the uniformity of temperature in the ladle.
Defectives such as roaster of the present utility model is avoided tempering, taken off fire, noise is big, combustion gas kind bad adaptability, reach the best blending of combustion gas and combustion air, flame jet velocity height has improved efficiency of combustion, has reduced the generation of pollutant in the burning, discharging waste gas is lower than national environmental standard, can effectively reduce the temperature difference of ladle and molten steel, reduce tapping temperature, improve converter life, increase output of steel, reduce raw materials consumption and ton steel cost.

Fig. 1 is the utility model roaster frame structure schematic diagram.
Fig. 2 is the structural representation of bung.
Among the figure: 1, hoist engine; 2, support arm; 3, airduct; 4, control valve; 5, high pressure positive blower; 6, bung; 7, high velocity temperature adjusting burner; 8 oil pipes.
The specific embodiment
As shown in Figure 1, 2, ladle is made up of staving and bung 6, on bung 6, roaster is installed, described roaster comprises hoist engine 1, support arm 2, airduct 3, high pressure positive blower 5, high velocity temperature adjusting burner 7 and oil pipe 8, high velocity temperature adjusting burner 7 is installed in middle at bung 6, connect airduct 3 and oil pipe 8 on the high velocity temperature adjusting burner 7, airduct 3 connects high pressure positive blower 5 through control valve 4, oil pipe 8 connects oil pump through control valve, bung 6 connects an end of support arm 2, the other end of support arm 2 connects pulley, and pulley connects hoist engine 1 through steel wire rope.
During work, after being extracted out by oil pump, fuel enters the high velocity temperature adjusting burner 7 of roaster, combustion air enters high velocity temperature adjusting burner 7 by high pressure positive blower 5 through airduct 3, fuel mixes, finishes burning with combustion air at high velocity temperature adjusting burner 7, the hot flame gas that produces is by high velocity temperature adjusting burner 7 ejections, and high velocity temperature adjusting burner 7 sprays hot flame gas speed greater than 100 meter per seconds, 200-1400 ℃ of outlet temperature adjustable range, strengthen gas circulation in the ladle, improve the uniformity of temperature in the ladle.
