METHOD FOR MAKING LITHOPLATE |
摘要 |
An improved method of making a lithoplate from a 5XXX type alloy which includes controlling the composition and casting practices to eliminate forming a pine tree metal structure in an ingot used for rolling a workpiece to be made into lithoplate. The method also includes homogenizing and hot rolling the ingot at a controlled initial temperature to produce a desired grain and metal microstructure in the sheet rolled from the ingot which is suited for providing a surface having substantially uniform and evenly distributed craters produced by an electrochemical method of graining. |
