Application of electromagnetic flowmeter in flow measurement of metallurgical industry

In the metallurgical industry, electromagnetic flowmeters are commonly used for flow control of continuous casting steel, continuous rolling, and steelmaking electric furnace cooling water. The monitoring of the cooling water leakage of the blast furnace tuyere is to compare the flow at the inlet end and the outlet end of the tuyere. If there is a difference, the alarm is given, and the measurement is required to be accurate and reliable. In the process of copper and wet zinc smelting in the non-ferrous metals industry, electromagnetic flowmeters are often used to measure the flow of ore slurry.

The flow measurement results of the metallurgical industry are mostly used for process monitoring and control, and the accuracy requirements are not high, but the stability and reliability requirements are high.

Common applications are as follows:

Measure cooling water for all equipment in the production process

Acid flow in coking and sinter plants

Hot rolling process to measure steel cooling water flow

Water consumption of clean steel plate for cold rolled steel plate

Liquid (acid-base) flow rate of cold-rolled steel plate for cleaning steel plate

Measuring the flow rate of the liquid during the surface treatment

Utilities measure feedwater and wastewater discharge flow control and total control

The steel industry belongs to the industry with large application volume of electromagnetic flowmeters. Due to the implementation of national planning, it has promoted the merger and reorganization of steel enterprises in various places. The successive transformation projects have a large demand for electromagnetic flowmeters; the demand in the non-ferrous smelting industry is compared. Complex, at present, alumina production enterprises use electromagnetic flowmeters in large quantities, and have certain applications in wet copper smelting, zinc, etc. However, in precious metals such as gold smelting enterprises, the penetration rate of electromagnetic flowmeters is relatively low, pending Further promotion.
