Description

Hot rolled slab stacker {Amassing device for hot slab}

The present invention relates to a slab stacker for storing and storing slabs at a high temperature, and more specifically, the slab produced by continuous casting by laying the upper surface exposed to the slab yard (playing slab, hot rolled slab; hereinafter hot rolled slab) ) To be stacked and stored, and to prevent deformation of the stacked hot-rolled slab and to prevent foreign matter from adhering to it.

Hot-rolled slabs are manufactured by separating metal components from raw materials such as iron ore, and melted metal flows along passages and hardens in a certain shape. Usually, the hot rolled slab has a thickness of about 100 to 300 mm and is processed into a metal material through a post process such as rolling. do.

The hot rolled slabs are produced by continuously casting molten metal in a melting furnace, such as a furnace, and cutting them to a certain length, thereby producing a plurality of hot rolled slabs at the same time.

Therefore, in order to put into the post-processing process, such as rolling process, to wait for a certain time or to adjust the temperature to a suitable temperature for the post-processing, the place where the hot-rolled slab is stored in the slabyard and the conventional Slab yards are laid with blast furnace slug or sand on the ground to level the slabs.

However, the conventional slab yard where the slab is deposited as described above has a high temperature and the slab, which is a weight body, adheres directly to the ground and is piled up so that the surface facing the ground is subjected to strong pressure, and the slab is subjected to the high temperature heat of the slab. As the slug is melted and fixed or sand is penetrated into the soft slab, it is cumbersome and inconvenient to remove such foreign matters during input into the post process, and the slab yard is repeatedly piled up. Over time, the flatness of the slab yard will fall.

The slabs stacked on the slab yard having the flatness are bent along the ground of the yard, and the curved slabs cause malfunctions when transported to the unmanned cranes, and cause various problems such as poor entry when entering the subsequent process. There was a flaw done.

On the other hand, in order to solve the above problems, various kinds of slab supports have been proposed, but most of them are made of metal structures with table-type pedestals to accumulate the slabs, and the hot heat of the slabs is transmitted to the metal pedestals. As the pedestal is heated, the strength of the pedestal is weakened, which limits the quantity of slabs that are stacked. When the slabs are not deposited, the heated pedestal is cooled. At this time, bending or torsion occurs due to the difference in the cooling speed of each part. The hot rolled slabs stacked on the bent pedestals are bent together along the bends of the pedestals, and thus induce the bends of the slabs.

Therefore, although a number of slab stackers have been proposed as described above, it is preferable to apply them to the surface of the slab yard. However, as mentioned above, the flat surface of the slab yard surface should be frequently performed, and foreign substances adhered to the slab are removed. Many processes are added, such as the need to be done, which leads to an increase in manufacturing costs.

The present invention has been made to improve the above-described problems, and the upper surface has a flatness and prevents deformation due to heat to prevent bending of the stacked hot-rolled slab and to prevent contact with foreign matter to prevent it from sticking to the hot-rolled slab. The purpose is to propose a hot-rolled slab stockpile.

In order to achieve the above object, the present invention is filled with a filler of agitated refractory material is filled into the main body is formed of a metal material and formed in the main body is divided into a plurality of partitions therein formed from a lower plate protruding upwards This is achieved by means of a hot rolled slab loading zone which allows hot rolled slabs to accumulate on top of the filler material.

The present invention as described above is that the main body is deformed by the hot heat transmitted from the hot-rolled slab deposited on the heating by reinforcing the strength of the main body by a plurality of fasteners are installed in the main body is integrated with the hardened refractory in the body. It is possible to prevent and support the hot rolled slab of the weight body, and the hot rolled slab is deposited on the upper surface of the main body to prevent foreign matter from adhering to the hot rolled slab because it does not come into contact with blast furnace slug and sand. The upper surface can maintain the constant flatness at all times to prevent warpage of the hot rolled slab, thereby preventing equipment accidents such as unmanned crane transportation work and poor entry of subsequent processes.

In addition, it reduces the additional work processes such as the removal of foreign substances attached to the hot slab and minimizes the strain of the hot slab, thereby securing the safety of the continuous manufacturing process. Especially, the flat work of the slab yard is excluded. It has the effect of reducing the manufacturing cost.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, Figure 1 is a perspective view showing the internal configuration of the present invention, Figure 2 and Figure 3 is a longitudinal cross-sectional view of Figure 1 is shown.

That is, the slab stacker of the present invention is formed of a lower plate 101 and a side plate 102 to form a plurality of partition walls having different heights in a rectangular cylinder in which the upper portion is opened, thereby partitioning the inner space of the cylinder into a plurality of sections and each partition portion. The lower plate 101 is integrally formed with a "Y" type fixing stand 105 which protrudes upward, but the installation direction is formed to cross at a right angle with the adjacent fixing stand 105 to constitute the main body 1.

In the above, the partition wall mounted inside the main body 1 is as shown in Figs.

Compartment partition 103 and the support partition 104, the partition partition 103 is divided into a plurality of spaces for inserting the filler material 2 in the main body 1 and the support partition 104 is in the partitioned space portion The height is made low so as to communicate with the adjacent space portion through the upper portion of the support partition 104.

On the other hand, the filler (2), which is agitated by the refractory and the fixing pin (201), is introduced into the partitioned inner space in the main body (1), and the filler (2) is shorted by the partition partition (103) and extends beyond the support partition (104). It is formed integrally.

In addition, the fixing base 105 protruding upward from the lower plate 101 is formed in a “Y” shape, so that the refractory material injected into the space portion is cured in the form of wrapping the fixing base 105 to be integrated with the main body 1, and the filling material is injected. (2) prevents cracking of the filler 2 to be cured and reinforces the strength by inserting and stirring the fixing pin 201 formed by bending the metal wire in a zigzag.

The present invention is embedded in the slab stacker to be exposed to the slab Yarn so that the upper surface is exposed to the hot slab, the stacked hot slab is placed on the upper surface of the filling material of the refractory material filled inside the body of the hot slab The hot heat remaining in the main body is not transmitted to the main body so that the main body can support the weight of the hot slab, and the filler 2 of the refractory material is combined with the main body 1 by the stator 105 and the support partition 104. When the filler 2 is stirred, the fixing pin 201 is mixed and stirred to prevent cracking of the filler 2 and to reinforce the strength thereof.
