Abstract

The invention provides a continuous blowing and casting furnace of oxygen-free copper ingots, which pertains to the technical field of manufacturing metal smelting and casting equipment. The furnace essentially comprises a furnace shell (3) which is externally coated with refractory bricks (1), a smelting furnace (4) and a deoxidation furnace (10) which are provided with an electric inductive heater (17) at the bottom and arranged in the furnace shell (3) in parallel, a bottom blowing chute (19) which is provided with gas permeable bricks (22) at the bottom and arranged between the smelting furnace (4) and the deoxidation furnace (10), a bottom blowing furnace end (11) which is provided with a casting gate (20) and bottom blowing bricks (12) at the bottom and connected with the deoxidation furnace (10), a diversion trench (21) which is distributed in an 'S' shape and arranged in the bottom blowing furnace end (11), a smelting furnace cover (5) arranged at the upper part of the smelting furnace (4) and a deoxidation furnace cover (9) which is provided with a vent (8) and arranged at the upper part of the deoxidation furnace (10), etc. The whole structure of the furnace has reasonable design, convenient operation, low cost, being stable and reliable and can effectively reduce the oxygen content and the casting cost of oxygen-free copper, thereby being easy to form mass production.

Description

technical field [0001] The invention relates to an oxygen-free copper ingot continuous blowing casting furnace, which belongs to the technical field of manufacturing metal smelting and casting equipment. Background technique [0002] The conductivity of pure copper is second only to silver, and its price is much lower than that of silver. Therefore, pure copper is widely used as a conductive material in the fields of electrical engineering and electronics after smelting, casting and processing. However, copper is easy to combine with oxygen at high temperature to form cuprous oxide. After solidification and crystallization, cuprous oxide is distributed at the grain boundary. The increase of oxygen content in copper reduces the conductivity of copper, which cannot reach more than 100% of pure copper. conductivity. The oxygen content in pure copper materials produced by conventional smelting and casting equipment is ≥ 50PPm, and with the development of electronics and commun...
