Description

Technical Field

[0001] The utility model relates to the technical field of advanced manufacturing and automation, and particularly relates to a vacuum consumable electrode furnace. Background Technique

[0002] The vacuum consumable electrode arc furnace, abbreviated as the vacuum consumable furnace, is an electric furnace that uses an arc as a heat source to melt metals in a vacuum environment. It is mainly used for melting refractory metals and rare metals, especially widely used in the field of titanium and titanium alloy melting. The structure of the vacuum consumable electrode arc furnace includes a furnace body with an internal crucible. A sandwich-type cooling water chamber is arranged outside the crucible in the furnace body. A vacuum chamber housing is vertically arranged above the furnace body. A vacuum pumping system is connected outside the vacuum chamber housing. An electrode is sleeved inside the vacuum chamber housing and is vertically arranged opposite to the crucible. The electrode includes a transition electrode located above and a consumable electrode welded below the transition electrode. The upper part of the transition electrode is connected to a lifting main shaft. The upper part of the lifting main shaft can slidably pass through the vacuum chamber housing through a sliding seal structure. A lifting control system is also provided for controlling the lifting of the vacuum chamber housing and the lifting main shaft. Among them, the existing connection method between the electrode and the lifting main shaft is to butt through the end plane and then clamp and fix the electrode by the fixture on the lifting main shaft. The process of this vacuum consumable furnace is as follows: The metal to be remelted is first made into a consumable electrode, and is firmly welded concentrically with the transition electrode to form an electrode. The fixture on the lifting main shaft clamps the transition electrode. The consumable electrode is put into the furnace body crucible. The consumable furnace is sealed, and the vacuum is pumped to a fixed value. The lifting main shaft descends to send the consumable electrode to near the bottom of the crucible. A bottom pad and an arc starter are placed on the bottom of the crucible. Under no-load voltage, arc discharge is generated by the instantaneous contact between the consumable electrode and the arc starter, and then stable arc combustion is achieved, forming a certain amount of metal molten pool. After the arc is successfully started, it enters normal melting. During normal melting, the current, voltage, melting speed, and vacuum degree are reasonably controlled, and the gas and low-melting-point impurities in the metal can be removed.

[0003] Nowadays, some vacuum consumable furnaces have problems such as small power supply and small vacuum pump configuration, resulting in unsatisfactory melting effects. At the same time, the crucible is a key component in the vacuum consumable furnace, and there is also room for improvement in its design and use method. It is necessary to solve the problem that the ingot cannot be removed by improving the inner hole design of the crucible; at the same time, reduce the pre-tightening force between the crucible and the bottom pad, reduce deformation, and improve the ingot quality.
