Tapping Temperature Measurement in Cast Iron Foundry
Pilger mill in tube rolling mills - hot and cold pipe detection
Metal Foundry : cast iron / investment casting plants
- Special wavelength for molten metal temperature
- Auto hot spot tracker distinguish between molten metal and slag
- No alignment required as >3.5 lacs pixels working
- Wide temperature range : 900 to 2450°C
Challenges
Reduce power consumption due to overheating
Reduce casting rejection rate caused by infrequent interval temperature measurement from the thermocouple
Reduce consumable cost
Increase personnel safety as hazardous area to look actual process during melting.
Solution
Special spectral range for molten metal.
Ensure limited influence resulting from unknown or changing emissivity.
Auto HOT SPOT tracker penetrate from top of slag.
Advance water cool housing 315°C.
Analog/ USB 2.0 and Ethernet GgE/ Po

Challenge
- The increasing flexibility of production lines requires a high adaptability of sensors. Continually changing object geometries, different temperatures and very high radiation or surrounding temperatures are no rarity.
- In a pilger mill those rough conditions can be found, among others in the production of seemless steel pipes. The raw steel blocks, each weighing a few tons are heated up first in a round oven at a temperature of 1300 °C.
- After descaling of the surface, the steel block is prepunched in a hole press with a strength from a converted 2000 t. In the next sloping rolling mill the growing pipe rotates between two rollers that are positioned at an angle to each other. The punching is widened to the size of the mandrel diameter.

Solution
- The sensor that was installed at this application is the HMD OKA 2038.38 G with tube OL 19.
- The signal of the infrared sensors controls the movement of centering device and abutment. The point of view is restricted by the tube and prevents disturbances by steam in the cooling phase.
- An optimum adaptation to the operating conditions is given due to the adjustable response temperature. The HMD with self-learning response temperature (Auto-Teach function) is suited to continually changing conditions.
- The compact sensor with a stainless steel housing can withstand surrounding temperatures of up to 75° C. The use of a cooling jacket raises this up to 200° C.
- Alternatively sensors with fibre optic cables are available which permit an application at ambient temperatures up to 600° C without cooling.
Customer Benefits
- Maintenance-free
- High temperature stability
- Recognition of hot objects at big distances
- Self adjustment with Auto-Teach or step switch for the response temperature
