Generally, as shown in FIG. 3, in an OCC device, a graphite mold 1 is attached to the furnace wall 3 of a holding furnace 2 using refractory cement 4, the outlet of the mold 1 is supported by a fixing plate 5, and a A heater 6 is provided, and the mold 1 is heated by the heater 6 to a temperature higher than the melting point of the cast metal, for example, about 1200° C. in the case of copper, and the molten metal of the cast metal is supplied into the mold 1. In this way, the ingot drawn out from the outlet of the mold 1 is cooled with water, and the molten metal in contact with the ingot 10 within the mold 1 is continuously solidified. In the figure, 9 indicates a seal plate at the outlet of the mold 1.

Graphite molds have an inert surface, making them suitable for casting copper and copper alloys, but OCC equipment suffers from oxidative wear due to high temperatures, making it impossible to maintain its shape for long periods of time. In other words, since the mold is heated to approximately 1200°C by a heater, it is oxidized by the atmosphere, and the mold exit part becomes oxidized and worn out in a relatively short period of time, losing the supporting capacity of the fixed plate and becoming unstable, and further oxidized wear and tear occurs. If it continues, it will lose its role as a mold and become uncastable.

In view of this, as a result of various studies, the present invention prevents oxidation wear and tear of the mold and enables stable casting for a long time.
This is a developed OCC device in which the outlet of a graphite mold attached to the furnace wall is supported by a fixed plate, the mold is heated above the melting point of the cast metal, molten cast metal is supplied inside, and the ingot is pulled out from the mold. This casting device continuously solidifies the molten metal in contact with the ingot in the mold by water-cooling the mold, and is characterized by having an oxidation-resistant tube inserted and fixed over almost the entire length of the mold's outer surface.

The oxidation-resistant pipe 7 is placed over the outer peripheral surface of the mold 1 so as to slightly protrude toward the outlet side of the mold 1, and the gap between the mold 1 and the oxidation-resistant pipe 7 is filled with a joint material 8 made of fire-resistant cement, and then dried and fixed. . This is attached to the furnace wall 3 of the holding furnace 2 using refractory cement 4, and a fixing plate 5 is attached to the inner surface of the portion of the oxidation-resistant tube 7 that protrudes from the outlet of the mold 1 to support the mold 1.

のである。 In this way, the mold 1 is heated to a temperature higher than the melting point of the cast metal by the heating heater 6 provided around the mold 1,
The molten metal in contact with the ingot 10 in the mold 1 is solidified by supplying a molten metal to be cast into the mold 1 and cooling the ingot 10 drawn out from the outlet of the mold 1 with water.

Filled with joint material 8 and dried, it is attached to the furnace wall 3 of the holding furnace 2 with refractory cement 4, and a fixing plate 5 is attached to the inner surface of the oxidation-resistant pipe 7 recessed from the outlet of the mold 1. This supports the mold 1.

In the present invention, by inserting an oxidation-resistant tube, such as a ceramic tube, over almost the entire length of the outer peripheral surface of the mold, it is possible to block the atmosphere and greatly reduce the oxidative wear and tear of the graphite mold. Furthermore, by supporting the ceramic tube at the mold outlet, the mold can be reliably supported from beginning to end even if some oxidation damage occurs to the mold in the vicinity.

On the outer surface of a graphite mold with an outer diameter of 25 mm and a length of 200 mm,
A ceramic (Al 2 O 3 ) pipe with an inner diameter of 30 mm, an outer diameter of 37 mm, and a length of 200 mm was placed over the exit side of the mold with a protrusion of 5 mm, and the gap between the mold and the ceramic pipe was filled with refractory cement as a joint material, and then dried. Fixed. As shown in FIG. 1, this was attached to the furnace wall of a holding furnace with refractory cement, and a fixing plate was attached to the inner surface of the portion of the ceramic tube protruding from the mold outlet to support the mold.

耐えた。 In this way, molten oxygen-free copper at 1200℃ is supplied into the mold, and the ingot drawn out from the mold is cooled with water, and the molten metal that comes into contact with the ingot in the mold is continuously solidified to form a 5 mm diameter oxygen-free copper metal. Copper ingots were manufactured and the service life of the molds was investigated. As a result, the mold withstood continuous use for 50 hours.

造不能となつた。 For comparison, we used a mold of the same size and attached it to the furnace wall of a holding furnace as shown in Figure 3 without covering its outer circumferential surface with a ceramic tube. Continuous casting was carried out. As a result, the mold was severely worn, and it became impossible to cast after about 6 hours.
