1. The cast iron cooling wall with the high efficiency and the long service life and the pre-penetrating pipe is characterized by comprising a cast iron cooling wall body (1) and a pre-penetrating water pipe (2), wherein the pre-penetrating water pipe (2) comprises an outer layer steel pipe (21) cast into the cooling wall body (1) and an inner layer water pipe (22) pre-penetrated in the outer layer steel pipe (21), and the inner layer water pipe (22) is a seamless steel pipe, a copper pipe or a stainless steel pipe;

  • the outlet and the inlet of the pre-penetration water pipe (2) are both positioned outside the cooling wall body, so that the inner layer water pipe still keeps the normal cooling function after the outer layer steel pipe is damaged, and the service life of the cooling wall is prolonged;

    the outer surface of the outer layer steel pipe (21) is provided with a metal nano transition layer, the thickness of the metal nano transition layer is 5-50 μ

    m, and the metal nano transition layer comprises the following components in parts by mass;

    nano nickel;

    70-80 parts of nano copper;

    20-30 parts of nano boron;

    1-2 parts of nano silicon;

    1-2 parts of nano rare earth yttrium;

    0.05 to 0.1 portion.
