Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support and guide device for coin pieces for continuous casting equipment, and more particularly to a support and guide device for coin pieces in which guide rolls and the like can be easily replaced.

The mirror support and guide device of conventional continuous casting equipment consists of a section dedicated to casting sections, which is usually called a support roll section, and which is dedicated to each shape of coin coins directly under the mold, and a section for each casting section that is successively provided below the support roll section. It is formed by a guide roll section shared by the guide roller section.

The support roll part is replaced alone or at the same time as the mold when changing the casting cross-section of a coin, and the guide roll part is shared by each casting cross-section, so when changing the casting cross-section, the roll interval is adjusted to the dimensions that suit each casting cross-section. It is now possible to do so. The guide roll section is composed of a guide roll, a frame, a spacing adjustment device, etc., and in the case of loading and unloading in which these components are removed or attached to the outside of the strand for maintenance etc., various types of rearranging devices are used. Generally, this is done all at once.

However, although this exchange method is effective when the number of strands is small, such as continuous casting equipment for slabs, such as 2 strands or less, it is effective in the case of multi-strand equipment with 3 or more strands, such as continuous casting equipment for blooms and billets. However, the strand spacing is small and the lateral space is extremely limited, which causes various problems. An object of the present invention is to provide a mirror piece support and guide device having a configuration that allows easy and efficient maintenance of the guide roll part in such conventional continuous casting equipment, even in the case of multiple strands. It is in. This object of the invention is achieved by the invention as summarized below.

The gist of the present invention is that the kamaha support guide section is provided in the village in order to match the cross-sectional shape of the coins that are continuously drawn out from the mold, and that are arranged opposite to each other so as to guide the coins. In a coin support and guide device for continuous casting equipment in which the interval between the inner and outer rolls can be adjusted, the main frame constituting the frame of the kama piece support and guide device is fixed to a foundation or a building, and the coin support and guide member is fixed. A spacing adjustment device for adjusting the spacing between the inner and outer rolls is installed on the main frame, and the inner and outer rolls of the coin support guide member are respectively attached to the inner and outer roll racks, and the inner and outer roll racks are attached to the main frame. A coin support and guide device for continuous casting equipment, characterized in that a reference block for maintaining a reference roll interval is disposed so as to be able to be held between the inner and outer roll racks on which the inner and outer rolls are attached. .

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

The mold 1 and the support roll 2 are attached to a vibrating device 3, and are continuously subjected to vibration while the molten metal is injected into the mold and drawn out downwardly via the support roll 2. Mold 1 and support if the casting cross-section of the coin is changed. Rule 2 is to be replaced all at once. The guide roll section 4 is composed of an outer roll rack 5, an inner roll rack 6, a fixed frame 7, and a roll interval adjustment device 8.

A roll 11 is attached to an outer frame 9 via a bearing 10 to the outer roll rack 5, and a roll 14 is attached to an inner frame 12 via a bearing 13 to the inner roll rack 6. One side of the fixed frame 7 has a pin 15 and a bracket 1
6, and the other one is link 17, pins 18, 19
and are fixed to a foundation 21 via brackets 20, respectively. The roll spacing adjustment device 8 includes an adjustment screw 22
, a positioning mechanism consisting of a nut 23 and a drive device 24 for the adjusting screw 22, a block 25 protruding from the inner frame 12, a hook 26 for engaging the block 25, a beam 27, and a hydraulic or pneumatic cylinder 28. It is constituted by a mechanism for pulling up the inner roll rack 6. Outer roll rack 5 and inner roll rack being carried out and maintained from the strand.

- The Lurak 6 is carried into the strand and installed with a reference block 29 sandwiched between each as shown in FIG. 3, with the distance between the outer roll 11 and the inner roll 14 ensuring the installation reference value A. Carrying in and out of the strand is carried out from a space where the mold 1, support roller 2 and vibrating device 3 are removed as a unit. Brackets are provided on both the inner roll rack 6 and the outer roll rack 5, and the two brackets are tightened via a reference block 29 using means such as bolts. Further, the loading and unloading of both roll racks is carried out by hooks provided on the upper portions of both roll racks 5 and 6 by hooking wires or chains and using lifting means such as a crane. The outer roll rack 5 and inner roll rack 6 carried into the strand are fixed with the outer frame 9 as a reference side by iron-fitting the protrusion 30 of the outer frame 9 to the recess 31 provided in the fixed frame 7. Further, the inner frame 12 is placed on standby while being laterally guided by an information guide surface 32 provided inside the fixed frame 7. Next, the adjusting screw drive device 24 is driven to advance the adjusting screw 22 and apply it to the back surface of the inner frame 12. Furthermore, the beam 2 is connected by the cylinder 28.
7, engages the hook 26 with the block 25, and pulls the entire inner roll rack 6 toward the adjustment screw 22, thereby absorbing various errors in each mechanism of the adjustment screw 22 and the adjustment screw drive device 24, and reducing the gap. It has no structure. 22, if it has a roll interval feedback and instruction function, it is reset to the installation reference value A in this state.

According to this method, each time the roll rack is maintained or replaced, the indicated value will be reset and restarted from the reference value, so it will not be affected by cumulative errors due to repeated operations or deformation of equipment, etc. It becomes possible to specify accurate roll interval values. After setting the mounting reference value A in this way, remove the reference block 29 between the outer roll rack 5 and the inner roll rack 6, drive the adjusting screw device 24, operate the adjusting screw 22, and set the desired value. Set the roll spacing B to match the thickness of the casting cross section.

When removing the frame rack from the strand, it can be easily done by reversing the procedure for carrying it in.

According to the present invention, the interval adjustment device between the main frame and the coin support guide member is fixedly installed, and only the mirror support guide village including the roll rack that requires maintenance most frequently is made into a cartridge structure as described above, and can be easily carried in and out. We created a structure that allows for this.

- The roll rack can be replaced extremely easily and in a short time, and the roll rack can be maintained outside the strand, making it possible to perform highly accurate centering and maintenance work. Furthermore, as a secondary effect of the present invention, when replacing the roll rack, there is no need for special equipment down time, and the replacement of the roll rack can be completed during the mold change work time associated with changing the casting cross section. This makes it possible to greatly improve the operating rate of the equipment, and since high-precision centering adjustment can be easily carried out, it has a great effect on improving the quality of coin coins that are minted. can. In the description of the embodiments of the present invention, only the replacement of a guide roll-type roll rack has been described. It is obvious that the same effect can be achieved by a completely similar mechanism. In addition, in the above explanation, it was stated that the main frame and roll spacing adjustment device are fixed to the foundation or building, but this does not mean that they are permanently fixed, and that they can be removed and carried out if maintenance is required. Needless to say.
