Flame & Gas Detection in Steel Manufacturing
Maintain safe working conditions with reliable flame detection & gas detection products
Detect Dangerous Gases & Flames Before They Create Harmful Conditions
The risk of fire within the steel industry is very high, which is why flame detection and gas detection products are critical to ensuring safe working conditions. Production machines within steel manufacturing facilities are particularly vulnerable to fire. They contain oil or other flammable liquids and sediments, alongside hot components, and electric ignition sources. Rosemount™ 975 Flame Detectors can detect flames with fast speeds and high accuracy, even at long distances.
Additionally, some of the processes carried out in the furnaces of a steel mill create hydrogen sulfide gas as a byproduct. When combined with other airborne particles from smelting and steelmaking, this combination can create a potentially fatal situation for personnel at the mill. Gas monitoring devices like the Rosemount 936 Open Path Toxic Gas Detector can detect the presence of hydrogen sulfide gas before it reaches dangerous levels.
