たものが汎用されてきている。(Conventional technology) In recent years, in continuous casting, with the speeding up of operations and the development of online casting width changing technology, the performance required of continuous casting molds has become harsher, and the durability of copper molds has been reduced. In order to improve the performance, recently, copper molds with a Ni plating layer formed on the inner wall surface, and those with a Ni-P or Cr plating layer laminated on the Ni plating layer (for example, Japanese Patent Application Laid-Open No. 52-52828 ), or those whose surface has been treated by thermal spraying with a self-fluxing alloy are becoming widely used.

という問題があつた。(Problems to be Solved by the Invention) However, even if a continuous casting mold is formed with these protective films, if it is repeatedly used, the protective layer at the bottom of the mold will wear out due to the sliding of the solidified shell.
It is necessary to frequently repair worn surfaces of the mold. When repairing this mold, the casting equipment must first be stopped, the mold must be disassembled, and then reassembled after the mold is repaired. Disassembling and reassembling takes a lot of time, which reduces the operating rate of the casting equipment. There was a problem of bringing

れるという問題があつた。 Moreover, if the protective layer is made of plating,
Since local repair is not possible, all the plating layer remaining on the mold surface must be removed and a plating layer re-formed, and the thickness of the copper becomes thinner each time the mold is repaired, resulting in several repairs. There was a problem that it became unusable. Furthermore, in the case where the protective layer is made of a self-fluxing alloy, heat treatment must be performed each time it is repaired, which causes thermal deformation, which limits its repeated use.

適用することが不可能であつた。 On the other hand, it is conceivable to use a metal material other than a self-fluxing alloy as a material for forming the protective layer, such as chromium or cobalt, and to form a protective layer by spraying the powder onto the surface of the copper material using a plasma spraying method. Because the thermal sprayed metal coating has weak adhesion to the copper material, it has been impossible to apply it to continuous casting molds operated in continuous mode.

This was done for the purpose of making it possible to repair it.

る。(Means for Solving the Problems) The present invention, as a means for solving the above problems, involves interposing a porous material to bring the anode into contact with the inner wall surface of a copper mold. An electrolytic plating layer is formed by electrolytically plating the anode and the copper mold while continuously supplying an electrolytic plating solution to the surface of the copper mold, and moving the anode along the inner wall surface of the mold. The present invention also provides a method for surface treatment of a continuous casting mold, characterized in that a nickel and/or metal carbide composite material is thermally sprayed to form a gradual coating.

うにしたものである。(Function) The present invention basically includes the following steps in order to form a thermal spray coating made of a metal carbide composite material.
Prior to the formation of the thermal spray coating, metal such as nickel or copper is applied using the so-called brush plating method, which improves the adhesion between the thermal spray coating and the copper mold material, and at the same time improves the adhesion between the thermal spray coating and the copper mold material. Disadvantages of thermal spray coatings made of metal carbide composite materials include the inclusion of nickel in the inner layer of the coating to suppress the reaction with slag, and the fact that it is highly hard but brittle and prone to cracks due to thermal shock. It was designed to compensate for this.

前記問題を解決している。 However, in the ordinary electrolytic plating method, the use of a plating bath is unavoidable, and therefore the mold must be disassembled and reassembled. Therefore, in the method of the present invention, the inner wall surface of the copper mold is Electrolytic plating solution is continuously supplied to the abutting porous material through the anode to form a fluid plating bath layer between the inner wall surface of the mold and the anode, and electricity is applied between the anode and the mold to remove the plating solution. The above-mentioned problem is solved by adopting a method of electroplating while moving the porous material together with the anode along the inner wall surface of the mold.
なお、溶射法としては、簡便かつ小形の装置を
採用できるガスフレーム溶射法を使用するのが好

させ、耐用度を向上させている。 Furthermore, the content of nickel in the sprayed coating is increased stepwise or continuously from the surface to the inside.In other words, the metal carbide composite material increases as it moves from the mold surface to the surface of the sprayed coating. By increasing the content continuously or stepwise, thermal shock and interlayer peeling caused by differences in physical properties between each layer, which are defects in thermal sprayed coatings with a laminated structure, are alleviated, and the spreadability and adhesion of thermal sprayed coatings are improved. Improves strength and durability.

That is, when the graphite anode 4 is wrapped in a sponge-like porous material and attached to the stylus 5, the positive electrode of the power supply device 6 is connected to the anode 4 with the lead wire 9, and the negative electrode is connected to the mold 1. On the other hand, the nickel plating liquid is supplied from the pump 8 to the short side mold wall 3 via the anode 4 and the porous material, while the nickel plating liquid falling down along the mold wall is collected in the tray 7 and pumped again by the pump 8. so that it is supplied to the anode 4. At the same time, a DC voltage is applied from the power supply 6 between the anode 4 and the mold wall 3, and the anode 4 is moved along the mold wall surface manually or by a drive mechanism, so that the nickel in the plating liquid is transferred to the mold wall.
