Abstract
The invention relates to a channel type induction heater for a tundish, which is used for heating the tundish and comprises a transformer (1) and the tundish (2). The tundish (2) body comprises an injection chamber (201) and a distribution chamber (202) which are separated by a separation weir (204). The lower part of the separation weir (204) is provided with a channel (205); the bottom part of the distribution chamber (202) is provided with a plurality of water outlets (203); the bottom part of the injection chamber (201) is provided with a through hole (207); and a communicating tube (206) penetrates the injection chamber (201) through the through hole (207). The transformer (1) comprises an upper iron core (101), a lower iron core (102) and a coil (103), wherein the coil (103) is sleeved on the upper iron core (101) part in the communicating tube (206). The channel type induction heater for the tundish of the invention has the advantages of high heating efficiency, low noise and quick response.
Description
(1) technical field
The present invention relates to a kind of induction heater, especially relate to a kind of tundish channel type induction heater, be used for the heating of tundish.
(2) background technology
Along with the development of metallurgical casting technique, the casting of the constant temperature of low overheat plays an important role to improving slab quality; Thereby in casting cycle, the liquid steel temperature of how controlling in the tundish has become the key factor that the foundry goods quality is watered in influence.
The mode of plasma heating once was used as a kind of solution and used, but showed that the plasma heating technique has starting the arc difficulty, noise is big and shortcoming such as efficient is low by industrial practice.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of efficiency of heating surface height is provided, noise is low and responds fast tundish channel type induction heater.
The object of the present invention is achieved like this: described heater includes transformer and tundish; Described tundish main body includes by flood chamber and distributor chamber, described flood chamber and distributor chamber are by separating every the weir, describedly be provided with passage every the bottom, weir, described passage is communicated with flood chamber and distributor chamber, the bottom of described distributor chamber is provided with some delivery ports, described flood chamber bottom is provided with a through hole, has a connecting pipe to run through flood chamber through through hole;
Described transformer includes upper core, lower core, coil, and described upper core is formed a complete iron core loop through communicating pipe and lower core, and described coil is placed on the upper core part that is positioned at communicating pipe.
Tundish channel type induction heater of the present invention, between described coil and the upper core hold down gag is housed, described coil lower end is provided with several stopping means, and described upper core top is set with an air channel, the top in described air channel is provided with busbar, and described busbar links to each other with coil by lead.
During work:
The power frequency alternating current of introducing in the coil by busbar induces alternating magnetic field in iron core-closed, described alternating magnetic field generates electric current in the molten steel that tundish flows, and the Joule heat that utilizes this electric current to produce heats molten steel; In heating process,, make that molten steel and the interior molten steel of distributor chamber in the flood chamber forms thermal convection current through passage, thereby make the molten steel on both sides be heated more even because that the molten steel that is positioned at flood chamber is heated is more; Near passage, the effect owing to pinch effect makes molten steel be formed with and is beneficial to the upwelling of inclusion floating, thereby foreign material are adsorbed on the tundish bag wall, has guaranteed the degree of purity of molten steel simultaneously.
Also can be the present invention simultaneously and be equipped with air channel and blower fan with heat transmission, the blower fan mouth is sent into cooling air over against the air inlet in left side, air channel, wind is drawn wind by stainless steel tube after entering the air channel, thereby has realized the purpose to the cooling of the coil in the stainless steel tube.
The invention has the beneficial effects as follows:
(1) owing to utilize electromagnetic induction directly the molten steel in the tundish to be heated, empty calory loses, thereby efficiency of heating surface height; And, can not resemble the plasma heating owing to the collision of fierceness produces noise because of utilizing electromagnetic induction principle heating.
(2) in the process of electromagnetic induction heating, owing to directly electric energy is converted into heat energy, input power and molten steel add hotsync to carry out, thereby has the fast advantage of response.
(3) in heating process, near the passage, the effect owing to pinch effect makes molten steel be formed with and is beneficial to the upwelling of inclusion floating, thereby foreign material are adsorbed on the tundish bag wall, has guaranteed the degree of purity of molten steel.
(4) because the transformer core ring is designed to upper core and lower core combining structure, thereby dismounting is easy to maintenance.
