Abstract
The invention relates to a vacuum consumable electrode arc melting furnace, belongs to the vacuum melting industry, in particular to a vacuum furnace which melts titanium ingot through vacuum consumable electrode arc. The invention mainly comprises a water cooled double-wall furnace body, a water cooled electric pole, a vacuum-pumping system, a consumable electrode holding system, a water cooled crystallizer, an arc stabilizing coil, a copper crucible, a water cooling system, an electric control system, etc. Under a normal operation state, voltaic arc is divided into a cathode chamber, an arc stream chamber, and an anode region. Through the voltaic arc, consumable electrode is melted and dropped into the water cooled crystallizer under the condition of high temperature, low pressure and slag free of voltaic arc, thereby being condensed to form the ingot. When passing through the 5000K arc zone, the melt drop reacts a purifying reaction due to the action of volatilization, decomposition, chemical combination, etc., thereby achieving stable ingot casting and crystallization.
Description
Technical field
The invention belongs to the vacuum metling industry field, particularly a kind of vacuum furnace by vacuum self-consumption electrode arc melting titanium ingot.
Background technology
Titanium is a kind of active metal, under liquid condition and the reflection of oxygen, nitrogen hydrogen and carbon be quickish, therefore guaranteeing to have high vacuum degree and improve the purity of smelting in smelting process is problem anxious to be solved at present.
Summary of the invention
This equipment be with by the titanium smelted or titanium alloy as the consumable electrode negative electrode, be anode with the water jacketed copper crucible.The electrode that has melted enters crucible with the drop form, forms the molten bath, and the surface in molten bath is become liquid state all the time by arc heating, is subjected to forcing cooling around bottom and the crucible, produces crystallization from bottom to top, thereby reaches the purpose of solidifying ingot casting.
Embodiment
This equipment mainly contains compositions such as water-cooled double-walled furnace shell, water-cooled electric pole, pumped vacuum systems, consumable electrode grasping system, water mold, stabilising arc coil, copper crucible, water-cooling system and electric-control system.Under the situation of normal running, electric arc is divided into the cathodic region, arc column district and anode region.By electric arc, consumable electrode is in high arc temperature, low pressure and do not have under the slag condition, and fusing is dripped in water mold, is condensed into ingot.When molten drop passes through the 5000K arc region, because effects such as volatilization, decomposition, chemical combination purifying reaction take place, thereby reach the ingot casting crystallization-stable.
Claims (1)
1. the method for usefulness arc heating as negative electrode, is smelted the crystallization ingot casting with cold-crucible as anode with workpiece.
