Temper Rolling:
a defining step in achieving steel quality

Flatness, surface finish and cleanliness for high-value applications.

Following annealing, the cold-rolled material is processed through the Temper Mill. This stage is essential for optimizing strip flatness and elongation while eliminating stretcher strain. It also enables the material to achieve the desired mechanical properties and surface finish.

Over the past decades, the growing demand for high-performance steels has driven temper mills toward increasingly stringent quality standards, with a strong focus on surface finish excellence, material cleanliness, and superior flatness.

Wet Temper Fluids – Kimya Technology

Operating conditions in the Temper Mill may vary considerably according to the technical requirements of the final product.

Kimya has a comprehensive line of products to cover any Client requirement. Kimya R&D Dept can also develop custom-made formulations to achieve the right compromise between conflicting requirements:

Address corrosion-related issues, even in environments with high humidity and salinity, enabling the overseas shipment of unoiled coils.

Reduce HSE impact by discontinuing use of Boron/Nitrites-containing products.

Improving strip cleanliness.

Strip lubrication to obtain significant elongations.

Performance Requirements

Wet Temper Fluids form water-based solutions that are applied at the mill entry section at concentrations ranging from 2-5%.

Several performance requirements are expected from a Wet Temper Fluid:

LUBRICITY

Sometimes physical and mechanical properties of the steel are achieved at the Temper Mill by taking high elongations.
Proper lubrication can be precisely tailored through custom adjustments in the Wet Temper fluid additive package.

DETERGENCY

Improve strip cleanliness and prevent dirt pick-up on the rolls.

CORROSION PROTECTION

Protection against corrosion in high-humidity and saline environments, as well as in the event of temper solution carryover.

COMPATIBILITY WITH PROTECTIVE OILS

No interference with the protective oil applied at the exit section.

HSE ASPECTS

Free of Boron, Nitrites and other toxic substances.

Advanced chemical solutions to optimize Temper Mill operations.
