AMETEK Land

Combining AMETEK 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 AMETEK 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

With AMETEK Land’s SPOTViewer software, the operator can quickly connect, log and view data from a SPOT GS pyrometer. Viewing and analysis is fully configurable using the flexible user interface.

The application-specific Auto Pour Pyrometer System is designed to provide accurate liquid metal temperature readings in the liquid stream, the most direct measurement location.

Using a non-contact measurement that does not interrupt the casting process, Auto Pour delivers one accurate, repeatable value, measured, and calculated for each pouring. This data helps reduce operating costs while improving casting quality.

The system detects the start and end of the pouring process, monitoring and outputting these readings for further analysis and storage.

A product of AMETEK Land’s continued innovation in precision temperature measurements, the Auto Pour Pyrometer System is specifically designed to support automated processes in the foundry industry.

A PROVEN MEASUREMENT

The Auto Pour system uses a high precision, spot application pyrometer and operates at a wavelength selected to ensure minimal errors from variable emissivity and atmospheric absorption and provides pouring stream tracking with a special field of view.

IMPROVED ACCURACY

The multi-function Landmark Graphic MkII (Auto Pour) signal processor uses a graphical display for improved measurement accuracy, usability and multiple interface.

PROTECTIVE MOUNTING

The pyrometer is protected against the harsh foundry conditions by an air/water cooling jacket. This also contains an air purge unit for maintaining a clean lens and window during operation.

Auto Pour is AMETEK Land’s application-specific solution for measuring liquid metal temperature in the foundry.

At the end of the tap the levels of slag and steel rapidly reverse. Quick termination of the tap after the alarm has been triggered is necessary to prevent excessive levels of slag in the ladle.

SDS uses a high-resolution thermal imaging camera to detect the transition between steel and slag. The dedicated thermal imaging camera has been specifically designed to survive in the harsh operating conditions and utilizes a particular wavelength to reduce obscuration caused by smoke and fume. Data is presented to the operator in real time enabling them to make informed decisions about the tapping process and the system provides clear alarm notifications.

SUITABLE FOR A VARIETY OF APPLICATIONS

SDS is suitable for operators of secondary steel making vessels (e.g. EAF, BOF) including stainless steel and can also be used in other smelting operations Eg copper and platinum. The system can also be used to indicate freeboard height if required providing a wide field of view.

IMPROVED PRODUCT QUALITY

Using the SDS has been demonstrated to improve operator response time and consistency at the end of each tap. This typically results in a reduction in slag depths of up to 25% compared to traditional methods of stream monitoring.

REDUCED DOWNSTREAM PROCESSING COSTS

The cost of additional downstream processing time and materials can be a significant burden on an operating plant. By controlling slag carry-over this costly downstream processing can be reduced or eliminated, improving plant throughput, product quality and operating margins.

AUTOMATIC OPERATION

As the tap commences, the application dedicated software records a data log and produces a live graph for quality control. A stream tracking mechanism is included to ensure reliable operation in typical installation conditions. When slag appears, and exceeds an operator defined amount, an alarm is automatically triggered. The system is designed to ensure accurate, real-time detection of steel/slag independent of charge weight and without operator intervention.

The Slag Detection System is AMETEK Land’s definitive solution for monitoring and reducing slag carryover in steel production facilities. It is proven to reduce slag carryover, save money and improve operator safety.

Combustion atmospheres using dirty fuels require  a thermal imaging solution with advanced spectral filtering and high resolution to deliver clear live images from within a furnace, boiler or incinerator.

The MWIR-B-640 provides a continuous and clear view, even through heavy smoke and hot furnace atmospheres, which is not possible when using visual camera systems.

The MWIR-B-640 allows highly accurate and fully radiometric temperature measurement image data to be taken, stored, and trended over the lifetime of the furnace or boiler.

The advanced IMAGEPro thermal imaging and data processing software supports long term data trending and enables the early detection of leaks and temperature variations to help optimise processes.

Operators have a clear view of the critical areas within the furnace or boiler with more than 300,000 accurate point temperatures, measuring in the range of 300-1200 °C (572-2192 °F) and 500-1800 °C (932-3272 °F). Providing advanced digital communications via the IMAGEPro software, the performance of the furnace or boiler can be monitored to easily identify hot and cold areas and any uneven heating can be viewed in real-time from the safety of the control room.

The high-resolution image, combined with the wide-angle field of view (90°), allows multiple areas to be imaged and measured simultaneously.

The MWIR-B-640 uses proven thermal imaging technology to accurately and continuously profile the temperatures within the furnace or boiler providing improved data accuracy through automation and minimising risk to personnel by reducing the need for personnel to be in the hazardous area around the furnace or boiler.

MWIR-B-640 is ideal for applications in Steam methane reformers, reheat furnaces,  biomass boilers, coal boilers, cement (kiln furnaces), heat treatment and annealing furnaces.
