BF Top Burden Viewing Thermal Imaging Camera — STV4900 Series

STV4900 Series

The BF top burden viewing camera helps steel plant operators monitor the blast furnace top burden surface in real time. It supports thermal imaging, temperature profile viewing, gas distribution observation and swing chute monitoring. Also, it uses nitrogen cooling and auto retraction support for high-temperature furnace conditions. As a result, operators get better visibility of critical BF top process behavior from a safer control location.

    Frequently Asked Questions

    STV4900 Series helps operators view the blast furnace top burden surface. It also supports gas distribution monitoring, swing chute observation and thermal profile viewing.
    A BF top burden viewing camera gives operators real-time visibility inside the top zone. As a result, teams can monitor burden behavior and process condition with better confidence.
    Yes. STV4900 supports thermal imaging and temperature profile monitoring across the burden surface.
    STV4900 uses nitrogen cooling. Therefore, it can support high-temperature BF top applications where camera protection is critical.
    STV4900 monitors the blast furnace top burden area. However, a tuyere camera monitors the tuyere zone, raceway behavior and PCI-related conditions.
    STV4900 is designed mainly for blast furnace top burden viewing. For general furnace, kiln or boiler viewing, HT-30 or HT-70 may be more suitable.
