Furnace Tracker For Slab Reheat

Description

Built for the steel industry, the DATAPAQ Slab Reheat system monitors the temperature profile of the slab at different points throughout its thickness as it travels through the furnace.The system consists of one or two data loggers, which in operation are protected by a special low height "phased evaporation" insulation system. This is designed to keep the data logger at a stable operating temperature,while the temperature in the furnace environment may be in excess of 1300°C.

DATAPAQ's powerful, yet easy to use Insight analysis software allows a fast and accurate temperature analysis of the run, which can be made within minutes of the slab leaving the furnace.The software is designed specifically for furnace users and includes all the analysis screens necessary to give maximum information on the process. The data logger, thermal barrier and software are designed and manufactured by DATAPAQ to ensure the highest possible accuracy, compatibility and quality.

  • Designed to travel through the furnace with the steel slab, no need for trailing thermocouples
  • High accuracy data logger ±0.3°C
  • Starts automatically on entering the furnace by temperature or time trigger
  • Powerful Furnace Tracker Insight analysis software
  • Replaceable insulation
  • Low height system for low clearance furnaces
  • Easy to set up and use
  • High thermal capacity barrier able to cope with stoppages during the trial due to roll changes

Evaporative Thermal Barrier

The thermal barrier contains various layers of insulation which slow down the passage of heat and create a temperature gradient within the system. The first insulation layer consists of Alumina Fiber blanket which has a maximum operating temperature of 1600°C and protects the evaporative thermal barrier. Inside the thermal barrier water slowly boils off and creates an environment where the temperature does not exceed 100°C, the working temperature of the data loggers. The inner insulation layers contained in the evaporative water jacket are structured to significantly boost the thermal capacity of the overall system, ensuring optimum performance during the process. The evaporative thermal barrier features "floating plate" technology to minimize distortion at high temperatures. The e evaporative barrier TB4133 contains a smaller barrierTB4132 which is designed to accept twoTpaq21 data loggers,offering them maximum protection against internal condensation, also heat when removing loggers from barrier.
Capacity: 24 litres
Thermal Duration: 9 hours at 1200°C constant temperature

Insulation Cage

The complete system is housed in a high grade alloy cage which holds the outer Alumina Fiber blanket insulation in place and affords some mechanical protection if the slab discharges from the furnace on a ramp.
Dimensions (H xW x L): 300mm x 575mm x 687mm

Thermocouples

The thermocouples supplied with the system are mineral insulated type K to ANSI specification MC 96.1 (Special Limits of Error). They have a special high temperature outer sheath. Part Number: PA076? - where the ? denotes length in meters from 1 to 9 meters (e.g. PA0761 = 1 meter length)
