The high-speed annealing process removes stresses created during cold rolling & allows mechanical properties to be developed in advanced steel & tinplate strip by following pre-determined profiles.
Blanking lines are used to create shaped steel pieces ready for use in automotive and other fabrication applications. Inspection of the blank surface ensures defects are not introduced during this conversion process.
High-speed tandem cold rolling mills often connected to continuous pickle lines need a reliable, verifiable automated solution to ensure defects are not introduced throughout the process.
Steel is typically color-coated in a continuous process line where paint is applied by rollers which is subsequently cured in ovens before re-coiling. Surface inspection can ensure a smooth, coverage of this coating.
Any cutting of metal sheets has the potential to damage the edges. To detect any flaws created by cutting, accurate inspection of the entire surface, including the edges, is required.
Decarburization is a process used in the production of electrical or silicon steel to remove carbon content by annealing. Surface monitoring can detect and classify any defects introduced during this process.
Thin foils require cold rolling to reach the desired thickness and surface quality. They are more prone to surface damage than thicker metals, and so reliable monitoring is essential to the process.
Thin cold rolled steel is tinplated by immersing in electrolytic plating cells in a continuous process. The quality of the tin coating can be verified by accurate surface inspection.
This is a specialty steel customized to have specific magnetic properties, and is usually made in thin, cold-rolled strip stacked together to form a laminated core for electrical motors or transformers.
This process involves applying a protective zinc coating to steel in a continuous galvanizing line to prevent corrosion. In-line inspection can ensure coating is successful, which protects metal sheets from corrosion.
Slab steel is rolled at high temperature to reduce its thickness making it suitable for coiling, while making sure that the coiled plate or strip has a uniform thickness with consistent shape and surface quality.
Inspection of the finished product ensures that substandard product is not sent out to customers. Automated inspection systems are more precise than manual methods, and provide a record for later checking.
Pickling in acid tanks removes surface scale or oxide from the hot rolled steel making it suitable for cold rolling.. Monitoring surface condition after pickling can verify the success of this process.
Punching is used to create holes in steel sheets, which can create surface defects in the metal. The edges of the holes can be monitored by our edge inspection system.
These are key materials for construction and transport projects and often require a high standard of surface quality. An inspection system which can expertly monitor these multi-plane surfaces is essential.
Steel recoiling lines are designed to facilitate edge trimming and final inspection of metal strip. Our surface and edge monitoring systems are ideal for inspecting quality before the steel is recoiled.
Slitting coils can leave them prone to edge damage. AMETEK Surface Vision provides an advanced edge monitoring system, while also inspecting both sides of the slit metal strip.
The temper or skin pass mill is used to establish required mechanical properties and to improve the surface finish of the steel product by further cold rolling. This is often the final process before shipment.
Often used to prevent rust, this is the process of thinly coating steel sheets with tin to produce tinplate, which is primarily used to manufacture tin cans.
Edge trimming is intended to remove impurities and defects from the edge of the metal strips. AMETEK Surface Vision’s system monitors the metal edge to ensure defect removal.
