Slab/Billet reheat process

Slab reheating process

Whether heat treating primary or secondary steel, monitoring and controlling temperature is essential for the product's quality, process effectiveness, productivity, and yield.Through-process temperature monitoring in such heavy steel processing applications is not, as you might assume, the simplest of tasks, but Tempsens has created a variety of innovative, one-of-a-kind application-specific technical solutions using years of experience in such sectors. Many customers throughout the world rely on such robust, secure, and dependable solutions to confidently comprehend, regulate, enhance, and validate their steel heat treatment processes.

The slab reheating furnace operation is a complex physical and chemical process which involves combustion, heat exchange among furnace wall, flame, skid and steel slabs, slab movement, and slab internal heat conduction.

To meet this need, Tempsens provides a selection of temperature profiling solutions made especially for use in the heat treatment process and slab reheating process.

APPLICATION

The standard range of evaporative thermal barriers are designed for use up to a maximum operating temperature of 1000°C. Please contact us for details of solutions for higher temperatures.

• Slab reheat, billet reheat process.
• High temperature and duration heat treatment processes without quenching can be achieved.
• Steel slab reheating
  It is crucial to check the drop out temperature of steel slabs before rolling. A complete image of both surface and core temperatures can be obtained from temperature measurements from up to 10 thermocouples, which can then be used to calibrate furnace management software and optimise furnace settings.
• Steel billet reheating
  It is essential that temperatures are consistent along the whole length of the steel billet, both at the surface and at the core, because steel billets must be reheated before operations like piercing to make pipes, rolling to make beams, or extruding to make wire. Our Furnace Tracker Systems are made to be mounted on the end of a reduced billet and move with the object as it passes through the furnace. This system is designed to travel through limited widths so that it can measure and record actual process conditions.
