となる欠点がある。 In a converter factory, the molten steel tapped from the converter into the ladle takes a considerable amount of time to complete the next process (e.g. degassing and casting), so a large amount of heat is generated from the surface of the molten metal during this time. Dissipation occurs;
The loss of energy was enormous. Therefore,
In order to prevent this heat dissipation, a method has conventionally been used in which a powdered (or granular) heat insulating agent is sprinkled on the surface of the molten metal. However, when the heat insulating agent is spread manually, there is a drawback that it requires a great deal of labor and time. Therefore, for the purpose of mechanizing the injection of the heat insulating agent, a device described in Japanese Utility Model Publication No. 54-33923 and a device described in Japanese Patent Application Laid-Open No. 53-18429 have been devised. However, in the 1970s,
The device disclosed in Japanese Patent Publication No. 33923 has a configuration in which a turntable is rotated, and has the disadvantage that the equipment is large-scale. Furthermore, it is expensive because it requires a Hanon cone with a complicated shape. Furthermore, JP-A-53-
The device of Publication No. 18429 is equipped with a heat insulating agent dispersion hopper that is rotatable around the axis of a ladle, and a chute that supplies heat insulating agent to the hopper from the side. This configuration has the disadvantage that the structure is complicated, such as the positional relationship between the chute and the hopper and an interlocking mechanism, and the hopper requires an opening/closing device.

布量が自由に調整でき、至便である。 The embodiment of the present invention is constructed as described above, and when the heat insulating agent is supplied from the receiving port 12 while the input chute 8 is rotated, the heat insulating agent is transferred to the inclined guide path 14 and the vertical guide path 15. The molten metal is dropped through the lower end opening 16 and spread along the outer circumferential slope of the diffusion member 17 onto the surface of the molten metal in the ladle 6. At this time, the heat insulating agent is sprayed over an area corresponding to the radius of the ladle 6, but since the charging chute 8 is rotating, one rotation of the charging chute 8 spreads the heat insulating agent almost uniformly over the entire surface of the molten metal. Ru. In this way, a large amount of heat insulating agent can be sprayed almost uniformly over the entire surface of the molten metal by one rotation of the charging chute 8.
Spraying time can be shortened, heat dissipation of molten metal can be prevented,
Labor saving can be achieved. In addition, since the heat insulating agent is sprayed while rotating the input chute 8, the heat insulating agent passing through the inclined guide path 14 is accelerated by centrifugal force, collides with the diffusion member 17 with force, and is dispersed. , the diffusion effect is large. Furthermore, the dustproof cover 7 can prevent the heat insulating agent from scattering. Furthermore, the lower part of the input chute 8 is inclined outward in the radial direction,
Since the charging chute 8 itself is configured to be rotationally driven, the structure can be simplified and can be provided at low cost. Furthermore, since the device itself can be configured to be small and lightweight, there are fewer restrictions on installation space and installation costs can be reduced. Furthermore, by adjusting the position of the adjustment plate 20, the amount of heat insulating agent sprayed on the surface of the molten metal in the radial direction can be freely adjusted, which is very convenient.

It is said to be able to swing freely. When the heat insulating agent is added, it is moved above the ladle 6 and used, and when not in use, it is stored or left on standby as shown by the imaginary line. Further, a dustproof cover 7 may be provided as shown by the imaginary line.
