JPS5829171Y2 - Ingot pedestal in soaking furnace - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a pedestal for supporting an ingot that is placed upright on the hearth of a soaking furnace.

On the hearth of a soaking furnace in which the ingots are heat-treated, a pedestal is installed to maintain a predetermined space between the ingots and to support the ingots upright.

By the way, Fig. 1 shows the shape of a single pedestal that has been commonly used in the past, and when such a pedestal A is arranged as shown in Fig. 2, it is formed by opposing semicircular parts. The bottom of the ingot is inserted into the hole.

Therefore, there is a risk that a row of ingots may fall down due to slight movement of the pedestal A. Moreover, since the pedestal A is made of ordinary steel, it generates a large amount of scale and has a short service life.

There were also drawbacks such as poor passage of combustion gas.

The present invention has been devised for the purpose of providing a pedestal that can eliminate such drawbacks, and an embodiment thereof will be described below based on the drawings.

That is, FIG. 3 is a perspective view showing the stand unit 1 according to the present invention, which is used as a set of four units of the same shape.

The unit 1 is made of a heat-resistant, abrasion-resistant, and high-strength electrofused brick in which the composition of corundum (A1203) and mullite (3A1203.2SiO2) is adjusted to form a suitable structure, and is made of a predetermined thickness t. An arcuate wall portion 2 is formed by cutting one corner of a rectangle having a width l into an arcuate shape, and a sloped wall portion 4 extending from the upper edge of the arcuate wall portion 2 to the upper surface 3 is further formed.

Therefore, the pedestal unit 1 according to the present invention consists of horizontal front and back surfaces, vertical side surfaces, the arcuate wall portion 2 and the slope wall portion 4. When using this, as shown in FIG. The slope walls 4 of each unit 1 forming a set are arranged so as to correspond to the lower edge surface of the circular ingot, and the side surfaces of adjacent units 1 are brought into close contact with each other, so that the same-shaped sets are arranged regularly. A continuous arrangement is adopted.

As described above, the present invention is a single pedestal in which an arcuate wall part is formed at one corner of a rectangle having a predetermined thickness and width, and a sloped wall part continues from the arcuate wall part to the upper surface. wear,
It is molded from high-strength bricks, and compared to conventional products, it can withstand long-term use and does not produce scale. It is also stable and there is no risk of the ingots collapsing together, and the passage of combustion gas is prevented. Because it is in good condition and has a large heat capacity, it is possible to reduce fuel consumption and stable operation can be expected.
