In particular, the preheating zone is an area for preheating the charging slab 2, and preliminarily warms up before heating the charging slab 2 in the heating table using the internal heat heated by the first burner 5 of the charging stand. Let's do it.

However, in order to minimize the leakage of thermal energy, it is important to form the preheating zone of the furnace by using a fireproof material that can sufficiently withstand heat while insulating the walls and the ceiling forming the space. In the case of the preheat ceiling, the installation process is very cumbersome because the refractory materials must be installed in the heating furnace at the same time by using the curing method, and in the case of the curing method, the separate curing (drying) time is considerably delayed and the start of work is delayed. There is.

In addition, in the case of a preheating ceiling of a general heating furnace, the ceiling surface is formed flat, which lowers the preheating efficiency, and in order to increase the preheating efficiency, a fireproof material having better thermal insulation and radiation performance than the currently used fireproof materials is used. It should be, but there is a problem that leads to an increase in cost.

The present invention has been made to solve the above technical problem, it is possible to increase the radiant heat radiated into the preheater of the heating furnace to increase the preheating efficiency, improve the convenience of the operator to install the preheater ceiling of the heating furnace. It is an object of the present invention to provide an insulating block for preheating ceiling of a heating furnace and a preheating ceiling assembly of a heating furnace.

The insulating block for preheating ceiling of a heating furnace according to the present invention includes a hanger brick formed with a locking groove so as to be hooked to the upper ceiling of the preheating zone of the heating furnace, and a block portion cured with a refractory material to surround the lower end of the hanger brick, A protrusion projecting downward is formed at the lower end of the block so that the radiant heat radiated into the preheating zone of the heating furnace increases through the block.

Meanwhile, the preheating stand ceiling assembly of the heating furnace according to the present invention includes a plurality of mounting beams arranged in a plurality of rows in a horizontal direction on the ceiling of the preheating stand of the heating furnace, and the plurality of mounting beams are caught by the plurality of mounting beams.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a heat insulation block for preheating ceiling of a heating furnace and a preheating ceiling assembly of a heating furnace according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view showing the pre-heating ceiling of the heating furnace using the insulation block for preheating ceiling of the heating furnace according to the present invention, Figure 3 is a view showing the installation of the insulation block for preheating ceiling of the heating furnace of Figure 2 It is a partial cross section shown and FIG. 4 is a side view seen from the AA line direction of FIG.

The heating furnace includes a slab (slab) is charged in the interior of the furnace in the order of the furnace entrance, charging zone (precasting zone), heating zone (heating zone), soaking zone (saking zone) It is most preferable that the insulating block 100 for preheating ceiling of the heating furnace according to the present invention is installed on the ceiling of the preheating furnace of the heating furnace.

The preheating zone constitutes a space for preheating the charging slab before it is heated in full scale. The preheating ceiling must not only have excellent thermal insulation performance to prevent high heat from leaking out in order to effectively use high heat energy. This is because the spinning performance to radiate heat back into the preheating space should be excellent.

Heat insulation block 100 for the preheating ceiling of the heating furnace according to the present invention, as shown in Figure 2, as a single piece of heat insulating material constituting the upper ceiling of the preheating of the heating furnace, a plurality of insulating blocks 100 is a heating furnace The ceiling is formed by being arranged above the preheating zone.

As described above with reference to FIGS. 2 to 4, the insulating block 100 includes a hanger brick 110 having a locking groove 111 formed to be caught on an upper portion of a preheating zone of the heating furnace, and a lower end portion of the hanger brick 110. And a block portion 120 cured with a fireproof material so as to surround 110A. It is preferable that the refractory material be made of the same material as the material constituting the wall portion in the heating furnace space.

The block portion 120 is cured with a refractory material on the lower end portion 110A of the hanger brick 110 and manufactured before forming a preheating ceiling of the heating furnace. In order to manufacture the ceiling of a preheating furnace, a skeleton is formed by using steel structures such as steel beams, and then cured into a ceiling shape using a refractory material as a whole. Is a completely different way.

In the case of the insulating block 100 for the preheating ceiling of the heating furnace according to the present invention, the ceiling is made of the same refractory material as in the prior art, but the manufacturing method and the shape of the insulating block 100 are different. Such differences will be described later, but the manufacturing time can be greatly shortened in the manufacture of the preheating ceiling of the heating furnace, and the energy saving effect can be achieved by improving its performance in terms of the radiation efficiency of the preheating ceiling of the heating furnace. It leads.

Figure 5 is a perspective view showing a preferred embodiment of the insulating block for preheating ceiling of the heating furnace according to the present invention, Figures 6 to 8 is a cross-sectional view taken along the line BB of Figure 5, of the heating furnace according to the present invention A cross-sectional view showing various embodiments of a heat insulating block for preheat ceiling.

As shown in FIGS. 3 and 5, the hanger brick 110 is formed to have a substantially rectangular horizontal cross section to have four sides, and is formed in a rectangular parallelepiped shape formed up and down, and the lower end of the hanger brick 110. The block portion 120 cured at 110A is also formed to have a rectangular horizontal cross section to have four sides. In addition, the lower end of the block 120 is formed with a protrusion 120A protruding downward so that the bottom surface 110A of the hanger brick 110 is not exposed to the outside during curing.

More specifically, the lower end portion 110A of the hanger brick 110 is provided inside the block portion 120, and the diamond-shaped protrusion 120A protrudes downward from the lower end portion of the block portion 120 to be heated. In the preheating zone of the furnace, the energy saving effect of radiation is greatly increased.

This is because, as with the insulating block for the preheating ceiling of the heating furnace according to the present invention, the radial surface area is increased by about 7 to 11% by the projection 120A, compared to the case where the projection 120A is not present. Increasing the radiation surface area insulates the high heat inside the preheater formed by the burner of the preheater, and at the same time, the preheating efficiency is increased because the performance of spinning to the side of the slab which requires preheating to be used again is further improved. In addition, when the preheating efficiency is increased, the temperature inside the preheating zone can be kept lower than the conventional one, thereby saving energy.

On the other hand, according to the present invention, it is possible to maintain the preheating zone at a temperature of about 1,000 ℃, thereby preventing the block portion 120 from being separated from the hanger brick (110).

Specifically, as in the embodiment of the present invention, when the lower end portion 110A of the hanger brick 110 is not exposed to the heating furnace space and only the block portion 120 that is a fireproof material is exposed to the heating furnace space, a heating table or crack In an environment where the temperature inside the furnace is very high, air permeability between the cured block part 120 and the hanger brick 110 may be poor and separation of the block part 120 and the hanger brick 110 may occur. .

However, the insulating block 100 of the present invention is not only applied to fabricate the ceiling of the preheating stage in which the temperature is kept relatively low in the heating furnace, but also due to the increase in the preheating efficiency due to the increase in the radiation surface area of the preheating ceiling, It can be maintained at a temperature lower than the inside of the conventional preheating zone, there is an advantage that can prevent the separation phenomenon between the block portion 120 and the hanger brick 110.

2 is a shape in which the ceiling area is increased compared to the case where the lower end of the insulating block 100 is flat by the protrusion 120A protruding downward from the lower end of the block part 120 according to an exemplary embodiment of the present invention. Is shown. In general, the amount of radiant heat transfer is proportional to the area, and it is natural that the radiation performance is improved according to the increased area. Such a difference in radiation performance, when considering the unit cost of the fuel used compared to the same ceiling area can create an effect of reducing the cost of about one third compared to the case of the flat ceiling of the furnace.

Looking at the specific embodiment of the preheating ceiling insulation block 100 of the heating furnace according to the present invention with reference to Figures 6 to 8.
