Description

[Detailed Description of the Invention] This invention relates to an auxiliary tool for conveying a wide continuous cast slab from a soaking furnace to a blooming mill by using an existing ingot conveying roller table.

Due to the continuous casting of steel billets, if the slab widths to be cast are diverse, the casting capacity will be reduced. Therefore, in order to improve casting efficiency, the width range of the cast slab is limited and cast, and this is then subjected to blooming rolling. There is an increasing tendency to hot-roll after milling.

In other words, some of the continuously cast slabs are heated in a soaking furnace or heating furnace and then transferred to the blooming line, but some of the slabs are wider than the existing table rollers. It becomes impossible to transport by normal means (flat state).

This invention provides an auxiliary tool that allows the above-mentioned wide slab to stand up in the width direction and be transported on the existing ingot transport table rollers. I will explain based on this.

1 shows the auxiliary device of this invention, which has a certain spacing (determined according to the thickness of the slab).

) A pair of left and right support wall plate members 7, 7 facing each other with S apart.
The support wall board members 1 and 7 are connected and fixed at one end by a connecting member 3 and a stopper piece 5 interposed and fixed at the back of the slab insertion gap 4 formed by the support wall board members 7 and 7. The portion is open and the other end is formed into an open shape.

Note that the length of the supporting wall board member T is shorter than the slab length.

Further, the opposing support wall plate members 7, 7 have a support wall plate member 7 whose upper opening edge 6 is enlarged to facilitate easy insertion of the slab A into the slab insertion gap 4, and the supporting wall plate member 7, which supports both supports. Consisting of a horizontal substrate 8 fixed to the lower end of the wall plate member 7 so as to stably support it, and a reinforcing member 9 that integrates the horizontal substrate 8 and both supporting wall plate members T to maintain their rigidity and strength. has been done.

The auxiliary device of this invention has a structure as described above in the embodiment, and when transporting a slab using this device, first the slab A extracted from the soaking furnace or heating furnace is moved to a reversing frame using a strip crane. (not shown) and then lifted up again by a crane and inserted into the slab insertion gap 4 from the widening upper opening edge 6 of the auxiliary tool 1 placed on the roller table B. Then, the slab A is held upright in the width direction by the auxiliary tool 1.

By starting roller table B in this way, slab A
is conveyed together with the auxiliary tool 1 while standing up while being supported by the auxiliary tool 1.

In addition, it is transported to a predetermined position, for example, the front table of the rolling mill,
In this case of separating slab A and auxiliary tool 1, that is, to take out slab A, once the end of slab A is clamped and restrained by manipulator C, roller table B is reversely activated, and slab A is clamped by manipulator C. Therefore, only the auxiliary tool 1 is sent back and the slab can be taken out.

In addition, if a short slab that is shorter than the support wall board member 7 of the auxiliary tool 1 is completely accommodated within the slab insertion gap 4 of the auxiliary tool 1, the auxiliary tool 1 should be placed at the tip of the manipulator C. When the roller table A is further operated in the normal direction in the state of contact, only the slab A is fed and removed from the auxiliary tool 1, transferred to the manipulator C side, and held by the manipulator C.

The slab is pulled out by the manipulator C, turned over on the mill front table, and then supplied to the mill.

According to this invention, it is possible to transport wide slabs by using the existing ingot transport table, and thereby, it is possible to use the existing blooming mill to straighten the width of the slab and to widen the slab (by using the existing blooming mill. It is possible to perform blooming even on a slab wider than the conveying table without being constrained by the slab width.

The auxiliary tool 1 includes a pair of support wall plate members 7 that maintain the slab insertion gap 4 and hold the slab from left and right sides, and a horizontal plate 8 that stabilizes the pair of support wall plate members 7 on a table roller. This makes it easy to insert and support slabs, and it is also possible to transport slabs that are smaller in width than the transport table.Furthermore, this transport aid eliminates the need to change the casting width of continuous casting slabs in many different ways. It is possible to obtain significant effects such as improved efficiency in continuous casting.
