Copper mould tube coatings
One of the continuous casting machine components relevant for high quality of semi-finished metal casting products is a mould. The CC machine mould includes the mould tube / plate that contacts directly with liquid metal, steel body fixing the mould and cooling jacket for effective cooling of molten metal.
Copper mold tube / plate is the most critical and high wearing part of the mould. In contact with liquid metal the copper mould forms an ingot by cooling a thin shell of metal and forming a solid crust. By extracting of the still-solidifying ingot and continuous feeding of molten metal to the mould a continuous strand is formed, that format is determined by the mould shape.
The mould quality, especially its wear resistance and service life of contacting surfaces, determines the efficiency and shutdown times of continuous casting machine. The mould service life can be of 20 – 25 tsd. tons of steel.
We use hard chrome plating which provides efficient anti-wearing protec
tion on the interior surface of the mould tubes and increase the life of mould tubes.
The plating thickness recommended by CCM will be controlled in the best range. As
for the coating of copper mould plates, based on our years of experience, we are able
to provide Chrome coating, Ni-Cr coating, Ni-Fe coating and Ni-Co coating to meet
the demand of various customers both at home and abroad.
