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

Description

Technical field: [0001] The invention relates to the field of copper liquid corrosion-resistant materials, in particular to a preparation method for depositing a cermet composite coating on an austenitic stainless steel base material by using a plasma spraying technology. Background technique: [0002] In the copper alloy casting process, the measurement of the temperature of the copper liquid is extremely important. The temperature of the copper liquid is directly related to the quality of the casting. The performance of other materials puts forward higher requirements. For a long time, domestic copper processing enterprises have adopted a variety of temperature measurement methods, such as optical pyrometers and contact temperature measurement, but only the surface temperature is obtained. In addition, ceramic materials such as quartz high-temperature ceramics, corundum, and silicon carbide are also used for measurement. The thermocouple temperature measurement protection...
