Abstract

PURPOSE:To reduce an equipment cost and to uniformize a water supply by forming a water jacket with an outer cylinder and attachable and detachable inner cylinder and arranging the manihold for water supply to the outer cylinder and a spray nozzle to the inner cylinder. CONSTITUTION:A water jacket 20 is composed of an outer cylinder 2, upper part cover body 9 and flanged inner cylinder 8 and the outer cylinder 2 is taken to be of the structure usable as well for the dimension of a billet 5. In this case the manifold (m) for water supply is fitted to the outer cylinder 2 and plural spray nozzles 3 are arranged at the inside of the inner cylinder 8 as well. A cooling water (w) is projected to a mold main body 1 from the nozzle 3 via a water supply hole 6, vibration table 7 and manihold (w). At the time of changing the dimension of the billet 5 the inner cylinder 8 and mold 1 are changed with the necessary dimentional one. Owing to the inner cylinder 8 and mold 1 being exchangeable the equipment cost is reduced and the water supply of the cooling water (w) is uniformized by the formation of a water jacket 20.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a water jacket type spray cooling mold applied to continuous casting equipment.

[Conventional technology]

As shown in FIG. 4, the conventional spray cooling mold has a spray nozzle 4 inside an outer cylinder 42 that supports a mold 41.
Four or eight headers 44 to which No. 5 was attached were installed, and cooling water W was supplied to each header.

[Problem that the invention seeks to solve]

Incidentally, it is preferable that the continuous casting mold support device in the continuous casting equipment can be used in common when the dimensions of the slab to be cast are changed.

For example, the dimension of the slab (45 in Figure 4) is 120-mm to 1
When changing to 40-mouth, the mold body (41 in Figure 4)
), and the mold support device can be used in common.

However, with the conventional support device for spray molding as shown in FIG. 4, the entire support device had to be replaced for each slab size.

Furthermore, it is not possible to evenly supply cooling water to the spray nozzles 45 because of the presence of a large number (4 or 8) of water supply headers 44.

The present invention proposes a spray cooling mold that can reduce the number of parts to be replaced as much as possible even if the dimensions of the slab change, and can evenly distribute cooling water.

[Means for solving problems]

The present invention provides a spray cooling mold for cooling the outer surface of a continuous casting mold with spray water, in which an outer cylinder and an inner cylinder having a lid at the upper end are removably connected to form a water jacket, and The present invention relates to a quarter-jacket type spray cooling mold, characterized in that the cylinder is provided with a water supply manifold, a spray nozzle is attached inside the inner cylinder, and the upper end of the mold body is connected to the lid.

[Effect]

In the present invention, the mold support is composed of a double cylinder body consisting of an outer cylinder and an inner cylinder which are detachably connected, and cooling water is supplied to each spray nozzle from a water jacket constructed between these inner and outer cylinders. is distributed, so the distribution of cooling water is uniform.

In addition, a water supply manifold is attached to the outer cylinder,
It is commonly used even if the slab size changes.

On the other hand, the inner cylinder has the spray nozzle attached on the inside (ie, on the mold side), has a lid at the upper end, and is separated from the outer cylinder and replaced when changing the size of the slab.

The upper end of the mold body is connected to a lid provided at the upper end of the inner tube, and is replaced together with the inner tube when the inner tube is replaced.

In the present invention, the water supply manifold may be fixed to a mold vibration table, and the table may be provided with a cooling water supply hole, and the cooling water may be introduced into the water supply manifold through the table. good.

〔Example〕

FIG. 1 and FIG. 2 are views showing an embodiment of the mold of the present invention, and FIG. 11 shows the assembled state when the dimension of the slab 5 is A.
FIG. 2 shows the assembled condition when the size of the slab 5 is B.

1 and 2, cooling water W enters the manifold m from the water supply hole 6 via the vibration table 7, is sprayed from the spray nozzle 5 through the water jacket 20 onto the mold body 1, and passes through the outer surface of the mold 1 to the cast piece. 5 is being cooled.

The quarter jacket 20 described above is constructed by combining an outer cylinder 2, an inner cylinder 8 with a lower end flange, and an upper lid 9, and uniformly distributes cooling water to the spray nozzle 3.

The outer cylinder 2 has a structure that can be used in common even if the dimensions of the slab 5 change, and the inner cylinder 8 with a lower end 7 and a flange to which the spray nozzle S is attached can be replaced at the same time as the mold body 1. Thereby, when changing the dimensions of the slab 5, parts can be replaced on a per rider basis, and the work can be completed in a short time.

The procedure for this replacement is as shown in FIG. 3, where the inner cylinder 8, mold 1, etc. are lifted upward and replaced with mold 1, inner cylinder 8, etc. of the desired dimensions.

In Figs. 1 to 5, the mold body 1 is made of copper or gun metal, 10I is a gel for connecting the outer cylinder 2 and the inner cylinder 8 via the lid 9, and 10 is a disk. 12 to the inner cylinder 8. The disk 12 is used to attach the mold body 1 to the inner cylinder 8. 111
11. is an O/g for water sealing between the outer cylinder 2 and the inner cylinder 8; 1 is an O-ring for water sealing between the shield body 1 and the inner cylinder 8.

〔Effect of the invention〕

As shown in Figures 1 and 2, in the present invention, by dividing the mold support device into an inner cylinder and an outer cylinder, (1) When changing the dimensions of the slab, only the inner cylinder needs to be replaced, reducing the work time. In addition, even when casting slabs of various sizes, the number of mold support devices is small, and equipment costs can be reduced. This has the effect of equalizing the water supply.
