 A high-precision digital pyrometer that delivers reliable temperature readings

Combining LAND’s cutting-edge, non-contact SPOT+ technology with specialised software algorithms, the SPOT+ GS is a high-precision digital pyrometer that delivers reliable temperature readings for galvanized and galvannealed steel strip.

The pyrometer provides accurate temperature measurement needed for close monitoring of the coating process, enabling automated furnace management that in turn delivers tighter control of product quality. Continuous on-line temperature measurement with the SPOT+ GS allows process line control systems to quickly and efficiently accommodate changes in strip dimensions or coating weight during changeover between different customer orders.

Building on LAND’s extensive application expertise in the steel industry, the SPOT+ GS is designed specifically for temperature measurement in continuous galvanizing lines to help ensure production of high quality products demanded by world leading customers in the automotive industry.

UNIQUE PRE-SET ALGORITHMS
The GS algorithm is dedicated to galvanized or galvannealed surfaces. The GS+ algorithm extends functionality to include the molten zinc surface seen on exit from the zinc pot.

CLOSE CONTROL FOR LOWER COSTS
The automated management provided by the SPOT+ GS enables furnace optimisation, which reduces heating costs, maximises throughput, and avoids excessive over-reaction. It also helps prevent coating defects and reducing problems during subsequent forming operations.

INTEGRATION FOR AN OPTIMISED PROCESS
Combining a range of digital and analog outputs, the SPOT+ GS fully integrates with furnace controls, PLCs and control software, providing the measurements needed to optimise furnace performance. This enables reliable and repeatable operation, producing high-quality products with minimal defects.

POWERFUL SOFTWARE SUPPORT
SPOTPro software provides a single control point to configure, store and view data for multiple SPOT or SPOT+ pyrometers and SPOT Actuators. Giving a complete overview of all devices on your network, SPOTPro allows you to independently configure data logging at response times down to 1ms for each pyrometer and set automatic triggers for data storage.  Live and historical data analysis assist you to trend and diagnose process issues.

IMAGEPro software provides a single control point to configure, store and view data and images from multiple SPOT+ thermometers, or a combination of SPOT+ thermometers and thermal imagers. Each device can be independently controlled and data logging configured with automatic triggers for image and temperature data storage.  IMAGEPro advanced software functionality allows SPOT+ measurements to be used for live background temperature, emissivity or dirty-window compensation of combined thermal imaging systems, as well as for single-point temperature measurements with a visible light process view.

Advances in Non-Contact Temperature Measurement for Continuous Annealing and Galvanizing Lines

We introduce how advances in accurate non-contact temperature measurements for continuous annealing (CAL) and galvanizing (CGL) lines ensure required metal characteristics and surface conditions are achieved in steel production. We will then focus on the SPOT+ GS, an advanced non-contact infrared spot pyrometer specifically designed for continuous, highly accurate measurements of coated steel strip temperature during the galvanneal reaction.
