Abstract

PURPOSE:To prevent a nozzle for charging from being distorted or damaged by the effect of heat by disposing a partition member between the nozzle and a moving die and fixing the partition member so as not to move together with the moving die. CONSTITUTION:A molten steel 1 is fed into a cavity 5 through a nozzle 3 from a well 2 as a moving die 4 moves. The molten steel in the cavity 5 penetrates into the gap G1 between the die 4 and a partition member 6 and the gap G2 between the member 6 and the nozzle 3 but the nozzle 3 and the member 6 are fixed and have no relative speeds and therefore the sliding force according to the movemet of the die 4 does not act on the nozzle 3. The deep penetration of the molten steel into the gap G1 is obviated and the member 6 is not overheated to the extent of losing its strength as the contact length L between the member 6 and the die 4 is made larger than the contact length (l) between the nozzle 3 and the member 6.

SUMMARY OF THE INVENTION An object of the present invention is to provide a steel plate continuous hook JIL device in which the nozzle is not damaged in the seal formed between the nozzle for hot water supply and the movable type.

According to the present invention, there is a
A linoleum member is provided, and the partition member is fixed so as not to move with movement g+H.

If the movement is +g or more, the surface of the partition member may be rubbed, but the surface of the nozzle will not be rubbed.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

31m and 4 show an embodiment of the present invention, in which a partition member 6 made of, for example, copper is disposed between the nozzle 3 and the moving tanks 4, 4' so as to surround the outer periphery of the nozzle 3. Place the fl゛ cut i; +i 446 on the fixed member 7 placed near the Qm 1:VI eye 2 so that it does not move together with the movable molds 4 and 4' in the direction of the arrow l\, and divide it as necessary. Cooling holes 8 are provided in the fl-cutting member 6 for supplying cooling water so that the member 6 can be cooled.

The molten steel 1 is sent into the cavity 5 through the nozzle 3 while the movable mold 4.4' takes about 1 and a half hours to move. The molten steel in the cavity 5 penetrates into the gap G1 between the movable die 4.4' and the partition member 6 and the gap C9 between the nozzle member 6 and the nozzle 3, or enters the gap between the nozzle 3 and the partition member 6. has been identified and there is no parallel 4 speed, so the moving type 4
．． The sliding force accompanying the movement of 4' does not act on the nozzle 3. (Through the molten steel that has penetrated between the cutting member 6 and the movable molds 4, 4' or the solidified molten steel that has penetrated,
Alternatively, the movable type 4.4' directly exerts a sliding force on the partition member 6 when it moves, but the partition member 6 is made of copper, for example, and even if it is moved in, the nozzle commercial People (for example, Boron Eye ≧ Ride: zz), j: are not easily damaged.

Also, Shiri Nori i1 Roy 6 always moves with 4.4' (Mushi, -F: Ij) r/February male leader aL4! : Nozzle 3-
The molten steel is filled with a gap of 1 fil G even if the 1 h steel touches the 1 h steel, and the 1 11 of the previous month 6 comes in contact with the molten steel.
, the cutting member 6 does not go all the way inside, so fl, the cutting member 6
(Mayu 1:) Stone 1 to lose moxibustion will not be overheated. By supplying cooling water from the cooling holes 8, the t46 can be cooled extremely, and the 100-sunori part 6 will not lose its strength. For this reason, it is possible to apply crushed metal or ceramic glue to the adhesive part 4 and 6.

5 and 6 show other embodiments of the present invention, in which the cross-sectional shape of the nozzle 3 in the width direction is not rectangular, but has 71 members, and 11
Between the cutting member 6 and the nozzle 3, a large material 9 (for example, alumina fiber of high alumina quality if the nozzle 3 is made of holon nitride) that has a worse transmission rate than the nozzle 3 is placed. An example of a device in which the nozzle 3 is prevented from cooling. In order to prevent leakage, a larger number of moving burrs 4 than 1. fl!l] are arranged, and 11 tt of molten steel is also supported in the cavity 5 by the lower moving mold. 3 damage can be prevented.

In the drawings 3 to 6 showing embodiments of the present invention, the same reference numerals υ as shown in FIGS. 1 and 2 indicate the same elements.

In addition, in the embodiments of the present invention, the case where a block type is used as the mold has been explained, but it is also possible to use a partition member between the nozzle and the mold even in the case of a twin bell type 1 or a belt and wheel with an 8v joint. to use or be able to use, its rhyme,
It goes without saying that changes may be made to the present invention without departing from the gist of the present invention.

According to the continuous steel plate casting apparatus of the present invention, 1) a material is provided between the nozzle and the movable die, so that the sliding force of the movable die is not directly applied to the nozzle which is heated to high temperature; Because the nozzle is designed to
(The nozzle is not damaged by the movement of ν. Therefore, it is possible to solve the bottleneck in putting continuous casting into practical use.

111) υ) Buried 111 or 1), the high temperature strength of the nozzle pressurizer should be 1/1 suppressed for the static steel filler. Therefore,
7, Le Meat) No can be changed to Ih < Tegiru and cheap hl → person to 1.14 river.

11) +l+i4 for nozzle) V can be made thinner, so movement +1!7 makes it 72. It is possible to reduce the handling thickness that is involved, and it is possible to reduce the erosion of rays and loops.

1'v'l IIψ Since the nozzle part can be made of copper metal, the movable part of the f-tri-nori member has a movable type in the nozzle part, so it is strong against separate attacks that occur and cannot be damaged. It's fleeting.
