Metering and monitoring method for high temperature melt displacement

Abstract

The invention provides a metering and monitoring method for high temperature melt displacement. The method includes the following steps: step one, installing a monitoring device, the monitoring deviceincluding a level gauge used for monitoring the liquid level height of high temperature melt in a runner and an alarm used for sounding an alarm; step two, obtaining the real-time discharge flow of the high temperature melt according to a unique expression so that the actual discharge of the high temperature melt can be obtained; and step three, judging whether to sound the alarm. Through the monitoring method, the effects the method are that the actual discharge of the high temperature melt can be monitored in real time, production metering data of the high temperature melt can be provided,and early warning can be realized by combining the actual discharge and preset discharge of the high temperature melt, so that the security of production can be enhanced.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a method for measuring and monitoring the displacement of a high-temperature melt. Background technique [0002] High-temperature melt is a typical intermediate product in the production process of the smelting industry. Taking the pyrometallurgical production of copper as an example, the mixed copper concentrate is smelted through matte making to obtain copper matte, and then the copper matte is sent to the converter for blowing. % above high-quality electrolytic copper. Since the operating temperature of the copper pyrometallurgy process is usually 1200°C or above, high-temperature melts such as copper matte, blister copper, and slag as intermediate products are usually discharged into copper / slag ladles, and then transported to the next process. During the melt discharge process, it is difficult to measure accurately with the flow measurement method under normal temperatu...

Problems solved by technology

Since the operating temperature of the copper pyrometallurgy process is usually 1200°C or above, high-temperature melts such as copper matte, blister copper, and slag as intermediate products are usually discharged into copper / slag ladles, and then transported to the next process. During the melt discharge process, it is difficult to measure accurately with the flow measurement method under normal temperature environment. The discharge volume is only estimated by the volume of the copper ladle / slag ladle, and the error is large. As a result, the current metallurgical industry generally lacks the measurement of intermediate products in the high-temperature smelting process method
