Abstract
A kind of directional electric arc heating device, be particularly useful for ladle or crucible, this device has the Graphite Electrodes that a consumption metal electrode that contacts with molten metal in the container and can the height above molten metal regulate at least, be characterized in that metal electrode is contained in the stationary installation that is arranged in the container top, the supporting arm of this electrode fixing device is provided with setting device.The electrode of this heating unit can be done horizontal or vertical motion, therefore repairs and changes simply, and be applicable to various exchangeable reservoir.
Description
It is a directional electric arc heating device that this invention relates to, and is particularly useful for ladle or crucible oven.
Generally speaking, when the metal electrode in this class smelting furnace was anode, Graphite Electrodes then was a negative electrode.
According to DE-OS3107454, crucible oven is to use direct current work.The negative electrode of this crucible oven is the arc electrodes of a job.Near the bottom of container, the metal electrode of metallic substance of the same race is housed.These electrodes are installed on the side facing to the container axis mid point.This side is to be built into by the refractory brick of being with conductive filler material.
Contacts electrode is installed in the side, and its advantage is that the position of liquid discharge orifice of bottom is unrestricted.Yet also there is its shortcoming this installation site, and promptly after the consumption of electrode that links together securely with container is intact, or when damaging, the work of the electrode that more renews is very complicated, and the expense costliness.
Task of the present invention will be created a kind of the sort of directional electric arc heating device of mentioning exactly when this paper begins.Its electrode can move on vertical and horizontal direction.Therefore, the repairing of electrode and more change jobs much simpler than existing structure.In addition, the electrode on the device of invention is applicable to various removable containers.
Rely on the of the present invention main and further feature of describing subsequently, solved task proposed by the invention.
According to structure of the present invention, be positioned at the movable electrode of container top, can regulate its depth of penetration according to production requirement.
Can easily contacts electrode and Graphite Electrodes be taken out from container, insert then in another container.Therefore, need not increase expense, just can quicken the process of this metallurgical process.
Owing to be direct cooling electrode in inside, so can prolong electrode life.The maximum heating load of contacts electrode, be with the contact surface of melt liquid on produce.So the present invention is being equipped with the heat protection with slag electrodes in contact lower end.
According to electrode installation method of the present invention, in fact reduced the yield of radiation of refractory materials.Because the consumption of electrode is less, reduced productive expense.This device also is applicable to vacuum method, and the method that adopts the protection gas-bearing formation.
The incidental sketch in back has been explained this invention in more detail.
Above following cupola well 1, Graphite Electrodes 2 and metallic contact electrode 3 are fixed together with the supporting arm 4 of integral body.Metal electrode in the example is a steel electrode.When setting device 6 regulates contacts electrode 3, Graphite Electrodes 2 is fixing by setting device 5.Setting device, such as on record DE-PS2125773 are a kind of helicitic texture devices.
Other, rather than in the structure of explanation here, the supporting arm of separate type can be set for Graphite Electrodes 2 and contacts electrode 3.
Supporting arm 4 is fixed together with the guidepost 7 of adjustable position.Thereby can regulate the height of two electrodes by hydro-cylinder 8.
When changing container, two electrodes can be improved, break away from original container then.
Electrode 2 should be adjusted to and make electric arc furnace keep stable status.
Contacts electrode 3 immerses in the molten metal.Setting device 6 is responsible for guaranteeing that electrode and molten metal 10 have enough contact surfaces.
By 11 positions of indicating slag blanket.
In example, contacts electrode 3 has an axial opening 12, and it can make electrode cool off (such as by cooling gas, as argon) rapidly.
This heater not only can use in the fixed location, also can be installed in a molten steel contracted affreightment Carry out work on the defeated car.
Claims (7)
