Abstract

PURPOSE:To extend the life of belts and to improve productivity in a belt type continuous casting device by using perforated plates for the contact surfaces of the belt retaining blocks on both sides and supplying a lubricant thereby decreasing the frictional resistance with the belts and decreasing driving force. CONSTITUTION:Perforated plates 14 are used for the contact surfaces of retaining blocks 12 and the contact surfaces thereof with belts 2 are lubricated by the lubricating oil from passages 16 for the lubricating oil whereby the frictional resistance is decreased in the press contact part of the belts and water-cooled side blocks 9 of a belt type continuous casting and frame moving device which adjusts the position where the solidification of a molten metal is completed to a specified position. The driving force of the belts 2 and the frictional damage of the belts 2 are decreased and since the belts are operated for a longer time, productivity is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a belt-type continuous casting apparatus, and more particularly to the above-mentioned apparatus in which belt wear and belt driving power are reduced.

Conventional belt-type continuous casting equipment includes those shown in Figures 1 and 2.0 Figure 1 is a vertical cross-sectional view perpendicular to the long side of the slab, and Figure 2 is F-F of Figure 1. It is an arrow view.

In Figure 1.2, 1 is the slab, and 1' is the upper surface of the slab 1 (
Molten steel, i.e. meniscus), 2 is a belt (general K, 1
~2 mmt steel), 5 is a pulley driven by a belt of 2 tons, 5' is a pinch roll for drawing the slab 1, 4
6 is a nozzle that supplies the molten steel between the belts 2 and 4 of the 5Fi tanditsh, and 6 is the stone pressure adjustment between the belts 2 (there is molten steel 1' between the belts 20, so the # steel 1'
7 is a spray nozzle, 8 is cooling water sprayed from the nozzle 7 (pressure equivalent to the height of 9 is a fixed side block (which completely prevents the molten steel 1' from escaping in the lateral direction), 10 is a cooling block. A water passage (cools the side block 9 and indirectly cools the side block of the slab 1), and 11 is a holding block (fixed) for the belt 2.

The belt-type continuous casting device described above moves the belt 2 in the direction of the arrow in Figure 1 according to the amount of molten metal poured. However, such equipment has the following drawbacks.

(1) Since the presser block 11 does not move and is pressed against the two belts in a fixed groove, the belt 2 rubs against the presser block 11 and wears out.

(2) Also, due to this friction, the driving power of the belt 2 increases.

(3) The life of the belt 2 is shortened due to wear, and the frequency of replacement increases, resulting in poor productivity.

The present invention has been made in order to solve the above-mentioned drawbacks, and in a belt-type continuous casting machine, a perforated plate is provided at the top end of a presser block that presses the belt 1, and lubricant is supplied through this perforated plate. This article relates to a belt-type continuous casting machine that has many unique features.

FIG. 5 is a diagram showing an example of an embodiment of the apparatus of the present invention.

In Figure 5, 2, 7, 8.9 are 2°7.8 in Figures 1 and 2.
Same as 9.

In FIG. 5, the belt pressing portion of the presser block 12 is a perforated plate 14. This perforated plate 14 is fixed by a back plate 15 and an outer frame of the presser block 12.
A passage 16 for lubricant supply is provided.

The lubricant is conveyed through the passageway 16 to the perforated plate 14 and seeps through the perforated plate 14, wetting the surface of the belt 2. In this way, the lubricant is supplied between the belts 2 and 4Q' and the t-block 9, and by wetting the surface of the belt 2, the wear of the belt 2 is reduced and the driving force is also reduced.

Note that, as the above-mentioned porous plate 14, for example, sintered metal, porous ceramic, nonwoven fabric of glass fiber, etc. can be used.

Furthermore, it goes without saying that the device of the present invention can be applied not only to the device shown in FIG. 5 but also to devices in which the side block 9 moves in synchronization with the belt 2.
