Abstract

PURPOSE:To cool blocks without using an intricate device and to prevent dropping of a cooling liquid into a slab by penetrating heat pipes into block casting molds, projecting the ends thereof and cooling the ends. CONSTITUTION:A suitable number of heat pipes 6 having high heat conductivity are penetrated into respective blocks 1 so as to intersect orthogonally with the moving direction and both ends of the pipes 6 are projected toward the outside of the blocks 1. Coolers 7 which cool both ends of the pipes 6 by a cooling liquid are further provided. If the cooling liquid is dropped successively from the coolers 7, both ends of th pipes 6 are successively cooled as the blocks 1 move. The blocks 1 are thus cooled from the inside. Cooling of not only both ends but one ends alone of the heat pipes is equally well.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a block type continuous casting apparatus.

[Prior Art] As shown in FIG. 1, a continuous slab casting apparatus is used to continuously move a block 1, which is a mold,
The molten metal 4 is supplied from the nozzle 3 of the tandice and 12 inserted between , 1 and solidified to form the slab 5 J:
Block-type continuous casting equipment is known. In such a continuous casting apparatus, it is necessary to cool the block 1, but conventionally, the block 1 has been directly cooled with a cooling liquid, so that the cooling liquid may fall onto the hot slab 5. It was dangerous and the coolant was not easy to seal.

[Object of the Invention] In view of the above-mentioned circumstances, it is an object of the present invention to cool a block without cutting a complicated device, and to solve problems such as sealing liquid falling onto the slab.

[Structure of the Invention] The block type continuous casting apparatus of the present invention has a heat pipe having high thermal conductivity penetrate through each block in a direction perpendicular to the moving direction, and both ends of the heat pipe are cooled on the outside of the block. It is designed to be cooled by liquid.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 2 and 3, an appropriate number of vibrators with high thermal conductivity are passed through each block 1 in the moving direction and the spinning direction of the slab 5. , a cooling device 7 is provided for projecting both ends of the heat vibro to the outside of the block 1 and cooling both ends of the heat vibro with a cooling liquid.

Note that the same reference numerals as in FIG. 1 indicate the same parts.

With this configuration, when the cooling liquid is allowed to flow down through the cooling device 7, both ends of the heat vibro are sequentially cooled by the movement of the block 1, and the block 1 is cooled from inside. Since the block 1 is cooled via the heat vibro, the cooling liquid does not directly come into contact with the block 1 and there is no fear of it falling onto the slab 5.

It should be noted that the present invention is not limited to the above-mentioned embodiments; for example, the number of heat vibros can be selected as appropriate;
P1 - The end of the vibro may be made longer and bent to increase the contact area with the cooling liquid, or it may be possible to cool only one end of the heat vibrator instead of both ends, and the thin ice Of course, various changes may be made without departing from the gist of the invention.

[Effects of the Invention] As explained above, according to the block type continuous casting apparatus of the present invention, by using a heat pipe, the block can be cooled without using a complicated device, and the cooling liquid does not fall onto the slab as in the conventional case. It can produce excellent effects such as eliminating the need to worry about
