PURPOSE:The marking mold which can be obtained by reinforcing the plated layer around both the end parts of the short side of the mold by a metal and/or a metal- ceramic compound exceeding the regular hardness, and can be cast continuously more than 600 times without causing a depression at both the end parts of the short side of the mold. CONSTITUTION:The steel continuous production mold is manufactured by arranging the plating layer 2 of single layer or multilayers, which makes Ni and/or Co contain P and/or B, or does not make the foregoing contain the same, on the base 1 of copper or copper alloy. In this case, the layer 2 around both the end parts in which a depression of the short side of this mold is caused is reinforced with reinforcing material consisting of a metal and/or a metal-ceramic compound. Fe, Co, Ni, etc. are used as the aforesaid metal. The above reinforcement is performed by means of sinking the aforesaid material as a wire rod 3, or welding 4 the wire rod 3. Also, as far as the reinforcement material is concerned, the metal and/or the aforesaid compound whose micro Vickers' hardness (200g load, 30 seconds) is more than 500 are used. |
