Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an easy-to-use construction of a new and improved finishing machine for nine continuous casting equipment equipped with a bottomless continuous casting mold for casting steel into metal 41. , IIL The present invention relates to a new method of manipulating a new dummy machine.

Generally speaking, according to the present invention, the 0/f-d- is provided with a swollen or enlarged bead-like O portion.

A lid that includes a bling element or section. Kazunaga input, the f-ring element is cast strand and sure or 7 ohm g in the direction of strand withdrawal! , form a knot, and this 7 ohm, the evening payment is a denominated parhead or casting strand) PO
By performing the tilting motion, it becomes possible to make sushi.
The parhead has a sealed end at its periphery 11.

To start up continuous casting equipment equipped with a bottomless continuous casting mold, i
Requires a construction bar with a T-par head. The diameter dieper head is suitable for use between the continuous casting machine and the hollow chamber, and is fixed in the hollow chamber with slight lateral play or wide clearance.゚Before starting the casting operation, - To prevent metal delayer out during noodle operation / (-d- to yP and casting
Seal the intermediary in the fight. Casting operation 011#1lllK
The metal poured into the hollow casting chamber 1w1i comes into contact with the cooled mold wall and the cooled /2-par head and solidifies. Shape 11 of cast metal t-muro V
A definite connection is formed between the protrusion and the casting strand, which connection makes it possible to pull the casting strand out of the cast iron with the aid of the dazzling.

Following the drive roll, the finisher is separated from the casting strand.

With this technology, 193γTo5J'J11 was approved US 1i41tNg 2.07 L644K Yoz ”
It is known to provide the final bar head with a force and f-ring element that can be inserted prior to the start of the S-building operation.

Knot releasably coupled to dieper head! The element has a metal casting at the beginning of the casting operation, so it is connected to the molten metal. Following the 5-separation cutting, the force VF9 remains as a mold in the hot strand and is therefore no longer possible for further injection operations. This of course incurs extra expense in terms of the work required for the rounding to obtain the force V delta volume and also for the rounding to insert the element into the construction bar vr. Generally, automatic removal is possible only at great expense in mechanical and control equipment.

A remarkable modification has been made by using a so-called permanent member head, which requires very little external force and requires only a small cost for the equipment due to its shape with the memebar expansion casting strand force and the pull. It can be automatically removed and used repeatedly in casting operations.

1971 1! US LI 1% Permit II approved on April 14th
No. 3,627,017 describes a permanent/f over 11' for continuous casting equipment equipped with a bottomless continuous casting shelter.

This permanent closing-bar yP is swollen and bead-shaped O
Power with parts F! Ring g! Continuous casting allows you to meet the basics and use it in many ways! IO Hollow is a secret drawing of the meaning of the building, which has a collection part in the y POllia piece, and the central part is Ikuhiro, and the mold wall is made of it! On the opposite side, the bead-like portion that constitutes the permanent zygote is supported. This multi-purpose metal element consists of a casting strand and a drawn meat to form a 7mm armor or a reliable assembly, and is removed by a tilting motion of the casting strand or a slanting movement to the final construction part. In addition, to the closing hole, an end is arranged on the circumference facing the injection side, and the sealed end is arranged in various ways according to the shape of the weld. .

In the case of continuous casting equipment for 2f and with a continuous strand guide, a continuous casting mold, and a support device for the screw in the expanding position, the i-meapard O structure with is sufficiently satisfactory for practical application. Things! For installations with large strands and billet, f-room or sheet par structures that require supporting devices in the secondary cooling area, or in fact without any strand guides and supporting devices, do not require permanent maintenance. When used, it is impossible to expand, and in areas where there is no support device and the holder cannot be expanded, it is possible that the predetermined holder may cause an undesirable gap in front of the sushi position. The appearance of any strand guide and support device and the curved shape of the strand guide typically increases the risk of linear misalignment in continuous casting equipment, including the HIRO Q-2 die.

Therefore, in view of the foregoing, a first object of the present invention is to solve the aforementioned drawbacks, and
It is an object of the present invention to provide a new and improved casting equipment which is not limited to the prior art structure.

The present invention and other specific objects relate to a new and improved permanent closure structure. # Suitable for use with structural wires, all strands or cutting shapes, the strand guide device is slightly bent, and does not cause any dislocation in the secondary cooling area without total heat, making it easy to use. It requires only a small amount of polishing, is inexpensive, can be sealed in the caster, and can be reliably removed from the cast iron at the sushi position.The present invention is also important! The objective is to create a new and improved member head structure KWI4 that allows for free initiation of casting operations even when the metal inflow into the hook is uncontrollable and the ferrous metal O flow corresponds to high injection rates.

Another important object of the present invention is to provide a complete construction of the improved device;
This is a novel method that allows the FF to be quickly and easily removed from the casting strand in a wide range of applications.

To carry out these and other objects of the invention, which will become readily apparent as the description proceeds, the present invention's final features include substantially 7. 7. The pulling part or the expansion element is arranged around the entire circumference of the body, with an exaggerated distance from the border that touches the sealed end of the do and laterally, and 7. A sealed end extending around the circumference is provided only in flat ends, as evidenced by the feature that the forming force, the printer part or element, gathers more than 1,000 yen into the closing part.

It is advantageous to use ζO/electronic paper for 7y-shaped cup portions or fins, plumes, slab shapes, or cross-section shapes that gather over the end pages. The strands are injected into the cast metal to prevent undesirable dislodgement in cooling areas without extended strand guides and support devices. Other advantages are provided by the VDO construction to the dowel perforation which extends the circumferentially of the sealing end in one go. In order to ensure that the final bar is not lost while the casting can be carried out in the next stock, the final bar is a device consisting of an outfeed roll table, which allows for reliable automatic casting expansion. I can make sushi. l! Automatic removal operation.

No extra equipment or expense is required; the force generated immediately after the start of the casting process, the shrinkage of the casting strand against the pudding element rapidly cools the unmaker, the coupling part, and the stiffening. let

As a result, the inflow of metal through the emergency stop after the start of the casting operation is not obstructed, and there are no problems such as starting the casting operation at a high casting speed in an uncontrolled casting system.

7. In carrying out the teachings of the present invention, the ring portion or element may have a different geometrical shape if it is possible to change the shape of the ring part or element to the dowel by performing a tilting or pivoting movement. One shot WJ4O that can be used with
An advantageous design is that if there is a 7f shape force, the pudding R section has a bay-shaped undercut surface K on one side! TS "t", on the opposite side substantially Kl111111m1mi [K, and the end WK
It is shaped by two divergent numbers 01111.

The solidification acceleration of the curved undercut coupling part, which has to substantially transmit the drawing-out force that starts the casting operation, can be improved if the undercarriage, the cut-off spring part, is provided with at least one cooling groove. It will be done. Due to the cooling fK, it is possible to clearly reduce the volume of metal between the unmaker, the toner, the printer part and the nearby casting part.

During the start of the casting operation, another device for rounding to prevent metal pre-heating is a dovecote with uncontrolled injection and exit, and a pigeonhole operating at high casting speed. , 1/1 of the size of the strand, which is located on the opposite side of the to, and is fixed in the same direction with the iim and the o space.
It is best to add 1[111 to 1B to 1/4].

In contrast to the rectangular cross-section of the cast strand, the hook OII layer is also preferably rectangular, and extends circumferentially to the footer surface, preferably with a uniform small space at the end. O Pigeon Cottage 7 Ivy OIJk1m and member can be easily moved from the PO end to the same shape. 7. It is necessary to select a pigeon coop with such a cross-sectional shape that the space between the base 011 and the circumferential sealing end is substantially uniform.

7. According to another 041 mold of the present invention, solidification is accelerated in the region of the circumferentially extending sealed end. The OmW area is soir*
o*wtos o to 80-preferably Hiro 70 to 8
0 - A stone intended to cover.

The slope or locking angle for removing the closing meeper head from the casting strand can be freely selected within a certain angle and can be accompanied by an effective fkf flow condition in the second cooling castle. For strands having a section without any strands or support devices in the secondary cooling zone, the present invention provides four
51 to 9C, preferably 60° to 90tJ incline or rotation angle, to provide for the transfer operation.

During the insertion of the sealing body during the casting operation 41, the pigeonhole to JIIWIA the casting operation of the KU-shifted strand can be advantageous if the sealing body O flat end face is arranged transversely to the casting strand OII moving wall. However, it is also possible to arrange the end face of the X1l-7, ri inclined to the longitudinal axis of the casting strand.

The tilting or swiveling motion is caused by the force between the meeper head and the casting strand threshold when the 0-order tilting or swiveling motion is supported by the 0-order tilting or swiveling motion during the start of the work. Gradually there is play between the part and the casting strand, the tally lance increases, and it is no longer possible to tilt or turn around the slanted end.
No movement is necessary, but if a tilted rotary movement is included in the removal operation 1, the present invention
The casting force during the horizontal cooling and bay-shape anchor, the door, the door, the opening, the opening, the opening, and the rotating movement of the shaft 1.
The f-ring part is also configured as an element 01 id device.

7. Place metal, force, and f-ring part of continuous casting equipment for Bay- or Fu-Aku II type strand. If the wire is inside the bay-strand guide device O, and the position of the closing meeper head, the casting strand, and the 011aO#F printer are directed to the point where they pass through the straightening machine, the casting form ■, and the joint part will change in flexibility. I am forced to do it.
