Hot-blast Stove Refractory Temperature Detection

The hot-blast stove is an important equipment in the blast - furnace iron - making system, used to provide high - temperature hot air for the blast furnace. The refractory lining (refractories) of the hot - blast stove has to withstand high temperatures and thermal shocks for a long time, and is prone to problems such as cracks, local overheating, wear, and spalling. Detecting the temperature of the hot - blast stove refractories through an infrared thermal imager can achieve real - time monitoring and fault early - warning, ensuring the safe operation of the equipment and improving its operating efficiency.

Project Application

Rapid Location of Overheated Areas: During the operation of the hot - blast stove, an infrared thermal imager detected abnormal temperatures in the top area. Timely maintenance was carried out, thus avoiding local refractory failure caused by high temperatures.

Monitoring of Crack Propagation Trend: A steel plant used an infrared thermal imager to monitor the surface crack area of a hot - blast stove over a long period, grasped its propagation speed, and formulated a refractory replacement plan in advance.

Application effect

Detecting the temperature of the refractory materials in the hot - blast stove through an infrared thermal imager can comprehensively enhance the safety and reliability of the hot - blast stove, providing strong support for efficient production.
