On the lead method and continuous casting and rolling advantages and disadvantages

1, on the lead method: this production method for the electrolytic copper melted directly on the lead out of the copper tube, the advantages of this process for the production of copper tubes: low investment costs, low production costs, high yield, inexpensive. Disadvantages: loose pipe organization, not high pressure, only suitable for the production of small-size air-conditioning copper pipe.

2, continuous casting and rolling method: this production method for the melting of electrolytic copper directly after casting hollow copper billet, after the planetary rolling production of copper pipe, the advantages of this process for the production of copper pipe: low production costs, high production efficiency, the disadvantage is: the pipe due to the organization of the loose, do not tolerate high pressure, limited to the production of small-size air-conditioning copper pipe.
