Thermal gas mass flowmeters for steel production processes

Project Overview

The application of thermal gas mass flow meters in the steel production process is mainly reflected in the following aspects:

1. Protective gas and purge gas: In steel enterprises, nitrogen is often used as protection gas gas and purge gas. For example, in the slag splashing furnace protection technology, nitrogen is used as the injection gas, and it is also used as powder spraying conveying gas, instrument gas, retardant gas, etc.

2. Ladle blowing argon refining process: Argon gas is used to improve the quality of steel in steel production. In the ladle argon blowing refining process, argon gas is blown into the molten steel from the bottom of the ladle. By controlling the pressure and time of the argon blowing, the molten steel is boiled and refined to achieve uniform chemical composition and temperature of the molten steel, accelerate chemical reactions, and remove harmful gases and inclusions. for the purpose of purifying molten steel. In order to achieve precise control of this process, a thermal gas mass flow meter is used to accurately control the inlet flow of argon gas.

3. Application in high temperature and corrosive environments: Due to its high accuracy, fast response, high sensitivity and other characteristics, the thermal gas mass flow meter is particularly suitable for flow measurement of large pipe diameters and low flow rates. And can be used in high temperature occasions and corrosive environments.

In addition, with the development of the steel industry, the demand for thermal processing equipment increases, and gas mass flow controllers are increasingly used in the metallurgical industry.
