Embodiment Construction

[0008] As shown in the figure, the process flow of the phosphorus-free deoxidation method of the present invention is: 1. Heating the melting furnace: according to the process requirements, the furnace body is heated and baked at low pressure, and the high pressure is gradually increased according to the time period until the melting furnace melts into a groove 2. Then tilt the furnace body backward about 65°; 3. Add material to the melting furnace: add some corner material copper in an appropriate amount at the beginning. Add a deoxidizer, that is, high-purity graphite powder 10, and the thickness of the cover is 20-80mm, and then use a fixed jib crane to lift the cathode copper to the upper mouth of the melting furnace, and stay at the upper mouth of the furnace for about a few minutes. After the surface moisture is baked at a high temperature at the furnace mouth, it is slowly put into the melting furnace. In this step, the thickness of the high-purity graphite powder cover...

Abstract

The present invention discloses a phosphorus-free deoxygenation method for oxygen-free copper tube horizontal continuous casting furnace. Said method includes the following steps: heating melting furnace, adding material into melting furnace, making molten copper be flowed into heat-insulating furnace, heating heat-insulating furnace, finally casting. It is characterized by that after the material is added into the melting furnace, when the level surface temperature of molten copper is up to 250 mm to 350 mm, a high-purity graphite powder deoxygenation agent can be added into the level surface of molten copper; and after the heat-insulating furnace is heated, the deoxygenation agent also can be added into the level surface of said heat-insulating furnace and can be used for covering said level surface, at the same time the nitrogen gas can be continuously introduced into the melting furnace and heat-insulating furnace.

Description

technical field [0001] The invention relates to a phosphorus-free deoxidation method for an oxygen-free copper tube horizontal continuous casting furnace. Background technique [0002] In the prior art, when the horizontal continuous casting furnace is used to produce oxygen-free copper pipes, when the melting furnace and the holding furnace are continuously fed to the liquid level, the holding furnace is heated to supplement the heat, and phosphorus with a content of 14% is added in the process for deoxidation , in order to meet the requirements of oxygen-free copper. When the casting temperature is reached, the casting billet is pulled through the crystallizer. However, this product requires that the phosphorus content be less than 0.003, and the method of adding phosphorus for deoxidation cannot meet the standard of oxygen-free copper. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects, provide a phosphoru...
