Problems solved by technology

At present, the measurement of oxygen content in molten copper is only based on the experience of experienced technicians in the smelting process. There is no instrument that can accurately measure the oxygen content in molten copper. Errors will inevitably occur in this empirical estimation, which leads to smelting The output copper does not meet the required oxygen content requirements, resulting in a backlog and waste of unqualified copper

specific Embodiment approach 2

[0024] The process steps described in Example 2 and Example 1 are exactly the same, except for the following differences: take 30 grams of cobalt powder with a purity of 99.99%, and 3 grams of cobalt oxide powder with a purity of 99%, and put them in a jade vessel Mix and grind for 40 minutes, pour the ground mixed powder into the cobalt oxide tube, and keep compacting, the mixed powder accounts for 40% of the volume of the cobalt oxide tube; pour the cobalt powder into the upper half of the cobalt oxide tube, after compacting, Cobalt powder accounts for 60% of the volume of the cobalt oxide tube.

specific Embodiment approach 3

[0025] The process steps described in the present embodiment 3 are exactly the same as those in the embodiment 1, but there are the following differences: take 40 grams of cobalt powder with a purity of 99%, and 34 grams of cobalt oxide powder with a purity of 99%, and put them into a ceramic vessel Mix in medium and grind for 30 minutes. Pour the ground mixed powder into the cobalt oxide tube and keep compacting. The mixed powder accounts for 89% of the volume of the cobalt oxide tube. Pour the aluminum oxide powder into the upper half of the cobalt oxide tube. Finally, alumina powder accounts for 11% of the volume of the cobalt oxide tube.

Abstract

The making process of oxygen measuring sensor for copper liquid includes filling the mixture of Co powder and Co oxide in certain ratio inside the lower part of ceramic tube, filling alumina powder or Co powder inside the upper part of the ceramic tube, fixing iron wire in the center of the ceramic tube, sealing the mouth of the ceramic tube with high temperature glue and drying. The sensor may be used to measure the oxygen content in molten copper inside smelting furnace accurately, and this can raise the quality of smelted copper material greatly.

Description

technical field [0001] The invention relates to the technical field of measuring instruments in the metallurgical industry, in particular to a method for manufacturing an oxygen-fixing sensor for smelting copper liquid. Background technique [0002] Copper materials with different oxygen content have different application places. For example, oxygen-free copper cables are widely used in karaoke machines. During the copper smelting process, the oxygen content of the copper liquid can be controlled through the smelting process, but only under the premise of accurately measuring the oxygen content in the copper liquid, can the smelting process be effectively controlled to produce copper materials with different oxygen contents. At present, the measurement of oxygen content in molten copper is only based on the experience of experienced technicians in the smelting process. There is no instrument that can accurately measure the oxygen content in molten copper. Errors will inevita...
