Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device for simultaneously replacing a single mold or a mold/cooling device for multiple strands in a multi-strand continuous casting facility.

[Prior art and its problems]

In continuous casting equipment, molds are replaced when casting size is changed, molds are replaced with new molds due to mold wear, and troublesome molds are replaced with new molds. Conventional mold replacement involves hanging wire ropes using a crane on the casting floor. For example, the old mold was taken out for each strand and then a new mold was installed, and in the case of multiple strands, the time required to replace the mold was twice as long as the number of strands.

Therefore, in multi-strand continuous casting equipment, it takes a lot of time to change molds, which has a negative impact on productivity. Also, during the exchange time,
There was a problem with the overhead crane being used exclusively.

This idea was devised in view of these circumstances, and its purpose is to create a mold batch exchange device that can significantly shorten mold exchange time by exchanging multiple strand molds at the same time, and improve equipment operation rate. Our goal is to provide the following.

[Means for solving problems]

The mold batch exchange device according to this invention is a device for simultaneously exchanging a plurality of molds in a multi-strand continuous casting facility, and includes a horizontal support member that can be raised and lowered by a lifting device and that can extend over all the strands. and a plurality of sets of hook members, which are disposed corresponding to each strand and are attached to the horizontal support member so as to be tiltable in the vertical direction, and whose tips can be attached to and detached from the hanging fittings of each mold; It is equipped with a tilting device capable of individually tilting the hook members of each set, and this tilting device includes a nut member rotatably attached to the horizontal support member via a horizontal pin, and a nut member that is rotatably attached to the horizontal support member via a horizontal pin. Screw together, handle on top,
It is equipped with a rotation drive device such as a motor, and consists of a bolt member whose lower end is pivoted via a horizontal pin to a connecting member of a set of hook members, and only the hook member corresponding to the mold that needs to be replaced is the bolt member. The tip of the hook member, whose posture is maintained by the bolt member, is locked to the hanging fitting of the mold that needs to be replaced, and the horizontal support member is raised by the lifting device to lift the mold all at once. The mold is then removed at the same time, and the process is reversed when a new mold is installed.

〔Example〕

This invention will be explained below based on an illustrated embodiment.

As shown in FIGS. 1 and 2, the mold batch exchange device 1 according to the invention includes a horizontal support member 2 such as a box beam that can extend over the entire strand.
, a pair of tiltable hook members 3 disposed on the horizontal support member 2 corresponding to each strand, and a tilting device 4 for tilting the hook members 3.

The horizontal support member 2 has a pair of support brackets 6 having pins 5 erected at two locations in total, and can be raised and lowered by engaging the hooks 7 of a lifting device (not shown) such as an overhead traveling crane with the pins 5. ing.

The hook member 3 has its base end pivoted below the horizontal support member 2 and is freely tiltable in the vertical direction.
The tip portion 3A can be attached to and detached from the hanging fitting 8 of the mold M.

The tilting device 4 includes a nut member 9 rotatably attached to the horizontal support member 2 via a horizontal pin, a handle 10A at the upper end, a handle 10A at the upper end, and a pair of handles at the lower end 10B. It consists of a bolt member 10 pivotally attached to a connecting member 11 of a hook member 3 via a horizontal pin, and the hook member 3 is tilted by rotating the bolt member 10 with a handle 10A.

Note that a motor may be used instead of the handle 10A.

The mold M is of a type that is integrally equipped with a cooling device C, and is designed to be vibrated by a vibrating device 12 during casting.

The vibration generating device 12 includes a vibration generator 13, a parallel link mechanism 14, a support plate 15, etc., and the support flange 16 of the mold M and the support plate 15 are fixed to the fixing device 1
7 to connect.

In the above configuration, the following steps are taken to remove the old mold.

(i) Release the fixation device.

(ii) Positioning device 18 consisting of an engagement protrusion and an engagement groove
Release. Here, the mold M is supported by a casting bed (not shown).

(iii) In advance, only the hook member 3 corresponding to the mold that requires mold replacement is tilted downward by the rotation of the bolt member 10, the other hook members are raised and retracted, and the replacement device 1 is placed on the mold. Hanging: The hook member 3, whose posture is held horizontally by the bolt member 10, is hung on the hanging fitting 8 from the horizontal direction.

(iv) All molds are transported out at the same time using a lifting device.

Next, when incorporating a new mold, the steps (i) to (iv) above may be reversed.

[Effect of idea]

As mentioned above, according to this invention, hook members that can be tilted in the vertical direction are attached to the horizontal support member covering all the strands in correspondence with each strand,
Since this hook member is tilted by a tilting device consisting of a nut member, a bolt member, etc., the following effects are achieved.

(i) Multi-strand molds can be replaced simultaneously and in batches, and the replacement time is the same as the conventional replacement time for one mold, making it possible to significantly shorten the mold replacement time.

Therefore, it is possible to increase the operating rate of the continuous casting machine and improve productivity.

(ii) Overhead cranes, etc. will not be occupied for long periods of time.

(iii) Even if not all of the strands of the mold need to be replaced, only the mold for the required strands can be easily replaced by taking the hook in and out.

(iv) Since the hook member is tilted by a tilting device consisting of a bolt member or the like, the hook member can be easily engaged with a plurality of molds that need to be replaced simply by operating a lifting device such as a crane. In particular, since the posture of the hook member is regulated by the bolt member, it is easy to insert the hook into a narrow space at the upper end of the mold.

Also, attach a nut member to the horizontal support member,
Since the lower end of the bolt member is pinned, the lower end of the bolt member does not protrude near the mold engaging portion of the hook, making the engaging operation easy and reliable.
