preparation example Construction

[0040] The present invention also provides a preparation method of a composite release agent for copper anode casting, which is characterized in that it comprises the following steps:

[0041] Prepare the composition of the composite release agent according to the following mass ratio:

[0042] BaSO 4 30%~70%

[0043] B 2 o 3 2.5%~15%

[0044] SiO 2 20%~45%

[0045] Al 2 o 3 1%~7%

[0046] CaO 1%~8%

[0047] where BaSO 4 The particle size is 1000-1200 mesh, B 2 o 3 , SiO 2 、Al 2 o 3 , The particle size of CaO is 150-200 mesh;

[0048] Add it to the mixer and mix it evenly before packing into bags for later use;

[0049] When in use, the prepared powdery composite release agent and water are mixed at a certain temperature to form an emulsion and stirred evenly.

[0050] The temperature is 65-85°C, preferably 80°C.

[0051] The ratio is a liquid-solid ratio of 1.8-2.2:1.

[0052] The present invention will be further described below in conjunction with ex...

Embodiment 1

[0054] Using the composite release agent composed in Table 1, mix water and release agent according to the mass liquid-solid ratio of 1.8:1, the water temperature is 70°C, stir evenly, control the temperature of the copper mold on the disc casting machine at about 150°C, and then put the prepared A good release agent emulsion is connected to the spraying system to start the normal production order. When the copper mold on the casting machine is transferred to the spraying station of the spraying system, the console controls the direct spraying of the release agent emulsion. Each piece of copper The amount of emulsion sprayed on the mold surface is 2.23kg / m 2. When the copper mold sprayed with release agent arrives at the pouring station, the console controls copper water to pour into the copper mold. The casting temperature of copper water is 1180°C. When copper water is poured on the copper mold covered with release agent, the powder The release agent is sintered to form a s...

Embodiment 2

[0059] Using the compound release agent composed in Table 2, mix water and release agent according to the mass liquid-solid ratio of 2.2:1, the water temperature is 85°C, stir evenly, control the temperature of the copper mold on the disc casting machine at about 170°C, and then put the prepared A good release agent emulsion is connected to the spraying system to start the normal production order. When the copper mold on the casting machine is transferred to the spraying station of the spraying system, the console controls the direct spraying of the release agent emulsion. Each piece of copper The amount of emulsion sprayed on the mold surface is 1.98kg / m 2 . When the copper mold sprayed with release agent arrives at the pouring station, the console controls copper water to be poured into the copper mold. The casting temperature of copper water is 1240°C. When copper water is poured on the copper mold covered with release agent, the powder The release agent is sintered to for...

Abstract

The invention discloses a compound release agent for copper anode casting and a preparation method of the compound release agent for copper anode casting, belongs to the technical field of copper smelting and mainly solves the problems that common release agents for copper anode casting cannot form compact films with larger adhesive forces, copper molds are damaged due to the fact that the release agents are washed open easily by molten copper and the white plate rate is high due to the fact that the release agents cannot be separated easily when anode plates are placed in water to be cooled quickly. The compound release agent comprises barium sulfate and composition of oxides, wherein the barium sulfate is precipitated barium sulfate; the composition of oxides comprises B2O3, SiO2, Al2O3 and CaO, to be specific, in percentage by mass, 30%-70% of BaSO4, 2.5%-5% of the B2O3, 20%-45% of the SiO2, 1%-7% of the Al2O3 and 1%-8% of the CaO.

Description

technical field [0001] The invention relates to the technical field of copper smelting, in particular to a composite release agent for copper anode casting and a preparation method thereof. Background technique [0002] The current copper smelting process Riotokump disc casting machine has been widely used in copper anode casting. The types of molds used by Outokumpu disc casting machines are divided into steel molds and copper molds. During the production process, steel molds will not have the phenomenon of anode plate sticking, but copper manufacturers cannot complete repair and processing after steel molds are damaged. to other related enterprises for processing, delaying production progress and increasing production costs. After the copper mold is damaged, it can be cast by the production enterprise itself, which greatly improves the convenience of production. [0003] Due to the large temperature gradient between the copper water and the copper mold during casting, th...
