Situation:

• During re-heating of material for the production of special long products and forged screws 1 to 2 % of oxide scale is formed.
• Scale causes defects at the surfaces.
• Scale causes damages of the forming tools (rolls, dies).

Solution:

• Selection of suitable coating ingredients for the production of coatings based on sol-gel technology
• Screening of different coating types in lab scale.
• Analysis of the interactions between coating and steel substrate.
• Industrial trials.

Operational benefit:

• Minimisation of scale formation at 1000 °C and reheating times of about 30 minutes of up to 30 % for the organic based pre-version.
• Implementation of the coating system into a system based on water and improvement of the efficiency of the coatings.
• Minimisation of scale formation at 1000 °C and reheating times of 60 minutes up to 100 % for the water-based system.
