Rolls (cold and hot mill rolls)

In its program, Production and Engineering Company ENCE GmbH highlights the most significant metallurgical equipment; this equipment complies with the highest international quality standards and may be offered to customers at competitive prices.

Technical Proposal

ENCE GmbH production and engineering company offers its customers various auxiliary metallurgical equipment and component parts necessary for repair and restoration of replacement parts and wear parts of rolling mills, hot dip galvanizing lines for steel coils, paint and polymer coating lines, automatic steel picking lines and sheet bending equipment.

The company ENCE GmbH offers a wide range of rolls for metallurgical plants where cold and hot steel and non-ferrous metal rolling is performed:

  • Cold rolling mill rolls
    • Solid-forged back-up rolls
    • Sleeved back-up rolls
    • Hot rolling mill working rolls
    • Cold rolling mill working rolls
  • Hot mill rolls
    • Solid-forged plate mill back-up rolls
    • Sleeved plate mill back-up rolls
    • Hot mill working rolls
    • Roll sleeves

ENCE GmbH production and engineering company delivers mill rolls from production facilities located in Korea. The parts are manufactured with high precision according to advanced technologies from high-quality wear-resistant materials ensuring high reliability and a long service life.

Temperature and production conditions are strictly observed during ingot forging. Bulk and surface hardening by radio frequency current and commercial frequency current is widely used. Roll steel is melted in electric arc furnaces. Machining production is equipped with modern facilities including programmed numerical control machines and high precision finishing machines.

Durability and wear resistance of rolls is systematically increased by means of:

  • searching for and applying new stronger materials;
  • perfecting manufacturing technology;
  • strictly complying with operating conditions by the user

High-alloy steel grades are used for manufacturing working and back-up rolls.

Rolls manufactured by the company ENCE GmbH are operated by many metallurgical and tube works of CIS countries.
