Method of producing electrocast belt

An electrocast belt production method by use of an electrocasting bath, the method comprising:

• a first step of producing a first set of electrocast belts having a required product quality without polishing a surface of any of the first set of electrocast belts in an electrocasting bath of a specific composition,
• wherein, in the first step, the first set of electrocast belts are produced without polishing a surface thereof, using an electrocasting bath which has been used in electrolysis with a cumulative amount of electricity of 0 kAh or more and less than 1,500 kAh, until the electrocasting bath has been used for a predetermined period whereby a produced electrocast belt fails to have the required product quality, and
• a second step of producing a second set of electrocast belts in the electrocasting bath which has been used for the predetermined period in the first step,
• wherein, in the second step, each of the electrocast belts of the second set of electrocast belts are produced with polishing a surface thereof, using the electrocasting bath which has been used in electrolysis in the first step with a cumulative amount of electricity of at least 1,500 kAh, so that each of the electrocast belts produced in the second step has the required product quality.
