Description

[Detailed Description of the Invention] The present invention relates to a slab weighing machine for a continuous casting machine. In particular, a set of slab weighing machines is equipped with a scale (for example, a load cell) for measuring slabs with large dimensions, that is, heavy slabs, and a scale for weighing slabs with small dimensions, that is, lightweight slabs. The purpose is to enable selection and use of slabs depending on their size, and to improve the weighing accuracy of lightweight slabs with small dimensions.

Conventionally, a set of weighing machines is equipped with a plurality of weighing scales having the same capacity, which measure the slab loads of all slab dimensions. Generally, the weighing accuracy of a weighing machine is determined by the maximum slab load, and the weighing accuracy becomes significantly worse when weighing small slabs.

The present invention solves this problem by providing a load cell support frame that is supported up and down on a foundation in the slab discharge path of a continuous casting machine, and on the load cell support frame, the slab support part is mounted on a roller. A slab support frame that protrudes from the conveying surface is supported by a weight scale, and the scale is usually a load scale that receives the slab support frame, and a load cell support frame that is movably supported to carry a heavy load. It consists of a weighing scale for light loads that accepts a slab support frame in place of a heavy duty weighing scale.

Examples will be described below. Now, the slabs 1 and 13 are transported by a carry-out roller 11 and a roller drive device 12 provided on a transport table of a continuous casting machine. Heavy slab 1 or light slab 13 transported
is stopped at a predetermined position by an electrical signal. Two heavy load load cells 3 and two light load load cells 5 are provided on a load cell support frame 4 under a slab support frame 2 that directly supports the slab 1 or 13 on the conveyance table. Note that the load cell 5 for light loads is installed on the load cell support frame 4 via a load cell lifting device 6.

The slab support frame 2 has a structure that allows it to be raised and lowered selectively by a load cell lifting device 6 or by lifting and lowering the load cell support frame 4. A slab support frame guide 7 is used as a lifting guide device when the load cell lifting device 6 moves up and down. is provided. As devices for raising and lowering the load cell support frame 4, a lifting cylinder 9, a lifting link 8, and a load cell support frame guide 10 are provided.

Now, when weighing a heavy slab 1, as shown in FIG. 1, the load cell 5 for light loads is in the non-operating position, and the slab support frame 2 is supported by the load cell 3 for heavy loads. . The heavy slab 1 on the carry-out roller 11 is lifted by the load cell support frame 4 by the downward movement of the lifting cylinder 9, placed on the slab support frame 2, and weighed by the heavy load load cell 3.

When the weighing is completed, the load cell support frame 4 is lowered by pushing up the lifting cylinder 9, and the slab 1 is transferred onto the carry-out roller 11.

Next, when weighing a light slab 13, as shown in FIG. state. At this time, the load cell support frame 4 is raised until there is sufficient clearance so that no load is applied to the heavy load cell 3.

As described above, two or more sets of weighing scales with different capacities are installed in one set of slab weighing machines consisting of multiple weighing scales of a continuous casting machine, and it is possible to select and use a weighing scale according to the weight of the slab. As a result, it has become possible to further improve the weighing accuracy of small-sized slabs.

In addition, two or more sets of weighing scales having different capacities are provided in one set of weighing machines to enable selective weighing of heavy and light slabs, thereby saving space for installing the weighing equipment.
