Problems solved by technology

The thickness of the coating film should also be strictly controlled. If it is too thick, it will cool slowly, and it is easy to form pores, and the surface of the casting is also easy to wrinkle; if it is too thin, it is easy to crack, and the surface of the casting will have marks.

Embodiment Construction

[0018] Hereinafter, embodiments of the present invention will be described in detail. It should be noted that the technical features or combinations of technical features described in the following embodiments should not be regarded as isolated, and they can be combined and combined with each other to achieve better technical effects.

[0019] A method of using a mold release agent for copper anode plate casting, comprising the following steps:

[0020] Prepare a release agent emulsion. Mix water and release agent according to the mass liquid-solid ratio of 1.8 to 2.2:1, the water temperature is 65°C to 85°C, and stir evenly, and maintain a stable stirring state during use to prevent the release agent from settling. The release agent used is a composite release agent, and its composition is calculated by mass ratio, including 30% to 70% barium sulfate, 2.5% to 15% boron oxide, 20% to 45% silicon dioxide, 1% to 8 % calcium oxide and 1% to 7% aluminum oxide.

Abstract

The invention discloses a method for using a release agent for copper anode plate casting, comprising the following steps: preparing a release agent emulsion; spraying the release agent emulsion; and forming a release agent protective layer by the release agent emulsion ; The protective layer of the release agent is sintered to form a sintered layer of the release agent; the sintered layer of the release agent is separated from the anode plate. Through this method, the release agent can form a sintered layer of release agent on the surface of the copper mold, reduce the occurrence of adhesion between the copper mold and the anode plate, reduce the bubbling of pores on the surface of the anode plate, improve the quality of the anode plate, and protect the copper mold. Extend its service life.

Description

technical field [0001] The invention relates to a method for using a release agent for copper anode plate casting. Background technique [0002] In the casting process of anode copper in the current copper smelting process, the Outokumpu disc casting machine has been widely used, and the mold types used by the disc casting machine are divided into steel molds and copper molds, and steel molds will not occur during the production process. The phenomenon of anode plate sticking to the mold, but the copper production enterprise cannot complete the repair and processing after the steel mold is damaged, and must go to other related enterprises for processing, which delays the production progress and increases the production cost. After the copper mold is damaged, it can be cast by the manufacturer itself, which greatly improves the convenience of production. However, due to the sticking phenomenon of the copper mold and the cast anode copper plate, when using the copper mold, in ...
