Egon Evertz KG is a global player in the technology and manufacture of copper moulds for the continuous casting process of steel. Our moulds are reliable and cost-efficient because of their long service life, highest standard of performance and 50 years of know-how and research, which we have put into engineering of top quality products.

Copper moulds play an important role in the continuous casting process. Their function is to receive the molten steel and guarantee a rapid heat transfer to the cooling water to enable quick solidification. The moulds must have excellent thermal conductivity and be resistant to thermal erosion and distortion.

Copper mould surface coatings

To extend the life of copper moulds a plating is required to coat the inside wall. The quality of the coating of the inside wall has a most significant role in determining a moulds service life. Over the years we have developed different coatings and improved continuously the quality and cost-efficiency of our continuous casting moulds.

Parallel coating

Prevents direct contact between the strand and the copper, controls thermal losses (in all cases, not dissipation) by varying the thickness of the coating and improves service life.

Multiple coating
Compensates hot spots, improve service life.

 

Partial parallel coating at the mould entrance or exit

Entrance: Reduces heat dissipation in the upper areas of the mould, prevents overlapping and improves service life.
Exit: Reduces heat dissipation at the mould end and improves service life.

Conical coating

Controls heat dissipation along the length of the mould, improves service life.

Depending on the requirements different coating processes and materials have to be applied, to receive an optimal result. Available coating materials are Ag, Ni, Cr, Mo, CrO, ZrO, Al₂O₃. The coating is applied  in a chemical, electrolytic or thermal process.

Continuous casting moulds - Shapes

We manufacture continuous casting mold tubes in copper and other commonly used copper alloys (Recommended materials are Sidex®, Cupragan® and Cupratherm®) . All types of cross sections, internal tapers and shapes which can be manufactured in our own planting facility. Examples:
