Abstract
A kind of novel passage for channel-type eddy-current heating tundish, belong to continuous casting technical field, its device comprises turbulence inhibitor, heat tunnel and heater, described turbulence inhibitor side is provided with opening, opening is connected to one end of heat tunnel, the other end of heat tunnel is connected to tundish, and described heater is arranged on outside heat tunnel.Passage of the present utility model is easy to original tundish to transform, and does not affect original tundish size and keeps long nozzle and the invariant position of tundish delivery port, and not being subject to the restriction of tundish original structure, does not affect the use of flow control device in original tundish; Passage length of the present utility model is longer than the passage length of existing tundish, and field trash is more easily adsorbed and is gathered in vias inner walls in the heating process of molten steel, and heating molten steel efficiency is higher.
Description
Technical field:
The utility model belongs to continuous casting technical field, is specifically related to a kind of novel passage for channel-type eddy-current heating tundish.
Background technology:
In casting process, there is heat loss in tundish to some extent, particularly at continuous casting, open water, ladle is changed and the period such as casting latter stage, inevitably causes larger temperature drop.Therefore seek the temperature drop of external heat source compensation Metal in Tundish, accurately control the best degree of superheat, stablely enter the great attention that crystallizer liquid steel temperature has caused people.
In recent years, along with the development of Technology of Tundish Metallurgy, plasma heating and channel-type eddy-current heating progressively become research emphasis.Plasma heating technology has starting the arc difficulty, noise radiation large, that produce has the shortcomings such as considerable influence to weak electricity system, and therefore Duo Jia steel mill has stopped using or abandoned this equipment both at home and abroad.
Compare with plasma heating, channel-type induction heating technique have the efficiency of heating surface high, pollution-free, simple to operate, be beneficial to foreign substance in molten steel floating in tundish, homogeneous heating and working environment safety coefficient compared with advantages of higher, original channel-type eddy-current heating tundish generally can be divided into single channel, binary channels and triple channel eddy-current heating tundish according to passage number.But, no matter adopting single channel, binary channels or triple channel, the use of channel-type eddy-current heating tundish will be carried out subversive transformation or abandon the original tundish of steel mill, and cost is huge, and heating effect is poor.
Utility model content:
The problem existing for solving existing channel-type induction heating technique, the utility model proposes a kind of be easy to transform on original tundish basis, novel passage for channel-type eddy-current heating tundish that the efficiency of heating surface is high.
For achieving the above object, the utility model by the following technical solutions: a kind of novel passage for channel-type eddy-current heating tundish, comprising: turbulence inhibitor, heat tunnel and heater;
Described turbulence inhibitor side is provided with opening, and opening is connected to one end of heat tunnel, and the other end of heat tunnel is connected to tundish, and described heater is arranged on outside heat tunnel.
Described heat tunnel is " U " type.
Described heater is electromagnetic heater, comprises iron core and coil, and described iron core is annular, is sleeved on heat tunnel, and described mounting coil is on iron core.
The utility model beneficial effect: passage of the present utility model is easy to original tundish to transform, do not affect original tundish size and keep long nozzle and the invariant position of tundish delivery port, and be not subject to the restriction of tundish original structure, do not affect the use of flow control device in original tundish; Passage length of the present utility model is longer than the passage length of existing tundish, and field trash is more easily adsorbed and is gathered in vias inner walls in the heating process of molten steel, and heating molten steel efficiency is higher.
Accompanying drawing explanation:
Fig. 1 is the structural representation of an embodiment of the present utility model;
Wherein: 1-tundish, 2-delivery port, 3-long nozzle, 4-iron core, 5-coil, 6-heat tunnel, 7-turbulence inhibitor.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of novel passage for channel-type eddy-current heating tundish, comprises turbulence inhibitor 7, heat tunnel 6 and heater;
Described turbulence inhibitor 7 sides are provided with opening, and opening is connected to one end of heat tunnel 6, and heat tunnel 6 is " U " type, and the other end is connected to tundish 1, and described heater is arranged on outside heat tunnel 6.
Described heater is electromagnetic heater, comprises iron core 4 and coil 5, and described iron core 4 is annular, is sleeved on heat tunnel 6, and described coil 5 is sleeved on iron core 4, and coil 5 is connected on high-frequency ac power.
During use, turbulence inhibitor 7 of the present utility model is arranged on to the below of long nozzle 3, molten steel flows down from long nozzle 3 in steel stove, while arriving turbulence inhibitor 7, its gravitional force is converted into kinetic energy, will flow into heat tunnel 6 from the opening part of turbulence inhibitor 7, at heat tunnel, be outside equipped with coil 5 and iron core 4, when needs compensate liquid steel temperature, coil 5 is passed into high-frequency alternating current, in molten steel, can produce induced-current and make its temperature increase, in steel flow, cross in the process of heat tunnel 6, also can realize removal of impurities process simultaneously.Temperature controlled processes can be realized by the electric current passing in artificial thermometric control coil at the scene, also can control to realize by automatic control equipment.Through the molten steel of heating, flow into tundish 1, and flow into crystallizer by delivery port 2, finally realize the coagulation forming of molten steel.
