方が予熱に有利である。(Construction and Effect of the Invention) The present invention will be explained below with reference to the drawings. FIG. 1 is a sectional view illustrating an embodiment of the present invention. In the figure, reference numeral 2 shows a state in which a metal container 1 containing molten slag 6 in a ladle lined with a refractory material is installed. The method for receiving the slag 6 into the metal container 1 is as follows:
The container 1 may be placed outside the ladle 2 to receive the slag, or it may be placed inside the ladle 2 to receive the slag directly. The metal container 1 is reinforced with reinforcing hardware 14,
It is set so as to be hooked onto the upper end of the ladle using a pot holder 13 as shown in FIGS. 1 and 2. When the metal container 1 is supported on the upper edge of the ladle 2 by the pot holder 13 in this way, a gap is formed between the bottom of the ladle 2 and the metal container 1, and the inside of the ladle is evenly dried and preheated. can. Also, when putting the metal container 1 in and out of the ladle 2,
It is convenient to carry out the work by hanging the hanging fitting 12 attached to the cutout hole 15 of the pot holder 13 shown in FIG. 2 on the hook of a crane or the like. It is advantageous for preheating to make the gap between the metal container 1 and the ladle refractory 4 as small as possible, and to make the shape follow the shape of the inner peripheral surface of the refractory 4 as much as possible.

めることができる。 In addition, the surface shape of the metal container 1 is as shown in FIG.
As shown in FIGS. 3 and 4, the bottom of the container 1 has a convex shape 16 toward the inner surface so that the surface area of the metal container 1 is as large as possible compared to the case where the surface of the metal container 1 is smooth. Increasing the heat transfer area to the bottom of the ladle, and making the container surfaces 5a and 5b uneven as shown in FIG. 3 improves heat transfer and shortens the drying preheating time.

る。 After the installation of the metal container 1 into the ladle 2 and the injection of the slag 6 are completed, a heat radiation prevention lid (hereinafter referred to as a heat insulation lid) is installed to prevent heat loss from the slag 6 due to radiation heat transfer and convection heat transfer to the upper part. Install 3. Thermal lid 3
is lined with a fireproof insulation material (e.g. ceramic fiber) that has low specific heat, low thermal conductivity, and low heat permeability (for example, ceramic fiber) as the inner lining material 7. The structure is such that the amount of heat dissipated is as small as possible. Furthermore, as shown in Fig. 1, by attaching a fan 8 to the insulation lid 3 to enhance the effect of convective heat transfer on the surface of the ladle lining refractory 4, it is possible to further speed up the drying preheating time. . 9 is an electric motor, 10 is a reduction gear, and 11 is a gear. In the above example, a method was described in which slag is injected into a metal container, placed in a container lined with refractory material, and used for drying and preheating the refractory lining, but the metal container is not used for further preheating. If so, a container for storing slag discharged from the furnace or
It can be used as a container for transporting slag.

更に上昇させることができる。(Example) The diameter of the metal container as shown in Figure 4 is 1800 mm at the top.
m/m, the lower part is 1600 m/m, the height is 2000 m/m, and after placing it in the ladle 2 in advance as shown in Figure 1,
Approximately 7 tons of high-temperature slag at ~1450℃ is placed in metal container 1.
was injected (slag depth from the bottom: 1600 m/m), and the heat insulating lid 3 was attached to the ladle mouth to perform preheating. Before the start of preheating, the metal container 1, the heat-insulating lid lining fireproof insulation material 7, and the ladle lining fireproof material 4 are all at room temperature. The mortar used as a joint material (200 m/m) was in a water-containing state. Figure 5 shows each part after the start of preheating (points a, b, and c shown in Figure 1)
The temperature change recorded over time is shown. Fifth
As can be seen from the figure, the temperature A of the outer surface of the metal container containing slag facing the refractory material lining the ladle is approximately max.
The temperature reached 800℃. Furthermore, the surface temperature B on the side of the metal container containing the slag of the refractory material lining the ladle rose to a maximum of 450°C, and decreased to approximately 200°C after 12 hours had passed.
The ladle outer surface iron skin temperature C is after 12 hours.
The temperature rose to a maximum of 130℃. As can be seen from the above results, it is possible to raise the temperature of the outer surface of the ladle to a maximum of 130℃ by preheating with one slag injection, and the moisture contained in the joint mortar of the refractory lining of the ladle can be completely removed. It was found that the ladle lining refractory 4 could be evenly dried and preheated. In the example, the results of one slag injection (7 tons) into a metal container were shown, but by repeating slag injection and discharge several times, it is possible to further increase the temperature of the refractory material lining the container.
