Ladle Applications

Steel Industry

The steel industry uses thermal sensors at many stages of production, from monitoring smelting and refining temperatures to cooling and annealing. Continuous temperature monitoring helps prevent overheating, improve energy efficiency, and maintain the desired properties of the steel products, such as hardness and tensile strength.

Preheated Application

Application

To measure the temperature of refractory vessels of Ladle. The Ladle is preheated before pouring the molten metal into it. Preheating of the ladle is essential as it helps to withstand the thermal shock of molten metal to the ladle and prevents its refractory linings of it from getting damaged. The ladle should be preheated to an optimum Temperature. If the ladle is cool, then the metal will explode from the sides of the vessel which hampers the safety and can be lethal. If the ladle is heated to a lower temperature refractory may crack. Very high-temperature heating of the ladle results in the decrease of the insulating properties of the refractories.

Process Temperature: 1500°C
Installation of the Pyrometer: At the top of the Ladle
Recommended Pyrometer: A450C FO PL

The Fibreoptic infrared thermometer is the most suitable product for this application. The pyrometer can view through the flames and can measure the temperature of the refractory directly. These sensors need very less maintenance and survive efficiently for many years.

A 450C FO PL

Temperature range : 600°C to 3200°C

Inside the Ladle

Application

To measure the molten steel temperature inside the Ladle.

After the preheating of the ladle, the molten metal is transferred to the Ladle. It is essential to know the temperature at this stage also.

Process Temperature: 1500°C
Recommended Pyrometer: A450C FO PL

A 450C FO PL

Temperature range : 600°C to 3200°C

Ladle Pouring

Application

Molten Metal String Temperature Measurement during Ladle Pouring into Tundish. Molten metal is poured from Ladle into Tundish to be used for other processes such as Casting etc. The temperature measurement is crucial for the homogenous quality to be maintained in further processes as well.
