The materials of copper mould plates should be the ones with good
tensile strength, fatigue strength, proper hardness, low elongation
and high heat conductivity coefficient. As a result, material
like CUAG
,CR-ZR-CU are widely accepted by
users of all countries.
Coatings:
Copper has lower hardness which leads to lower anti-abrasive
property. Therefore, the area at the lower part of the moulds,
where the stress increases drastically due to shells, will be
more severely worn. To increase the life time of copper moulds,
Uniform mould interior surface plating with suitable hardness is
needed. Most of the copper mould tubes for small size billet
casting are not used in any casting system where there are rigid
casting stream support, therefore they are very sensitiveto be
worn. We use hard chrome plating to increase the life of mould
tubes. The plating thickness 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 Cr coating, Ni-Cr
coating, Ni-Fe coating and Ni-Cr coating to meet the demand of
various customers both at home and abroad.
Notice:
1. Please use the
copper mould plate within one year.
2. Please store the
copper mould plate in someplace dry and well
ventilated
3. Keep the copper
mould plate away from acidic materials, especially the internal
coating surface.
4. Polish the external
surface of the copper mouldplatewith
sand paper if oxidized.
5. Pouring the molten
steel to the center of the copper
mouldplate
6. Avoid internal
surface scratch of the moulds caused by manual
operation.
