Description

Kiln top hanging brick

[ technical field ] A method for producing a semiconductor device

The utility model relates to a kiln top hanging brick, in particular to a kiln top hanging brick which is fireproof and not easy to break and is suitable for a top brick of a kiln.

[ background of the utility model ]

In kilns for producing ceramic articles such as tiles, for example roller kilns, dome-shaped roofs are rarely used, since dome-shaped bricks are difficult and time-consuming to manufacture and assemble. Instead, the kiln top is formed by using general refractory bricks and then suspending the bricks in the air on an iron frame.

It is convenient and fast to hang the firebricks on the iron frame, and in order to facilitate hanging, the firebricks (adiabatic bricks) are usually lighter and make the structural strength thereof weaker. Therefore, the light refractory brick is affected and eroded by hot airflow in the kiln, and after being used for a period of time, the light refractory brick is easy to break without warning and fall off, and often falls off on a product to damage the product or falls off to break a fire baffle plate and the like. Such a problem causes the workers to be Colosseus in war even the broken refractory bricks are stuck in the kiln, causing the whole kiln to stop running, and the workers need to wait for the temperature of the kiln to be reduced so as to enter the kiln to clean the broken refractory bricks or damaged products, thus causing a small loss of productivity.

Therefore, how to improve the above-mentioned problems has been a goal of practitioners in the related art.

Referring to fig. 1 to 3, a kiln top hanging brick 1 according to a preferred embodiment of the present invention is provided, which comprises a body 10, a hanging member 20 and a plurality of wires 30, the technical contents of which are described in the following.

The body 10 may be made of various known refractory bricks, and is preferably porous, so that a plurality of pores are formed in the body 10 to reduce the heat conduction coefficient of the body 10, increase the heat preservation effect of the body 10, and prevent the heat energy in the kiln from losing. The porous body 10 may also be reduced in density to reduce weight. When the body 10 is manufactured, a plurality of polystyrene particles can be mixed into the slurry, and then the polystyrene particles are melted to leave air holes in the process of sintering and forming the slurry at high temperature. The body 10 may be a rectangular body (cuboid), or may be other shapes, such as a cylinder, a corner post, etc., depending on the actual application requirement. In addition, taking a rectangular body as an example, the length of the body 10 may be 250mm, the width may be 250mm, and the thickness may be 130 mm; the body 10 may also be formed by bonding or combining multiple parts.

The body 10 includes a top portion 11 and a bottom portion 12, the top portion 11 is located above the bottom portion 12, the top portion 11 is close to and includes the top surface of the body 10, and the bottom portion 12 is close to and includes the bottom surface of the body 10. The top 11 and the bottom 12 are only portions of the body 10 at different positions, and they may not be different or separated by structure or material.

The hanger 20 may be disposed on the top 11 of the body 10 for hanging or mounting the body 10 on an elevated iron stand (not shown). The hanger 20 may be a metal piece that is partially disposed in the top 11 of the body 10 (e.g., inserted into the top 11, clamped by the top 11, etc.) and partially disposed outside the top 11 (extending beyond the top of the body 10); the hanger 20 may also be longer and partially disposed in the bottom 12 of the body 10 (not shown). The hanger 20 has a through hole 21 so that an iron stand (not shown) passes through the hanger 20.

The way in which the hanger 20 is provided to the body 10 may be, for example: the body 10 may comprise two halves 10A and 10B (each having a thickness of 65mm), the halves 10A and 10B are formed by sintering at high temperature, and then the opposite surfaces 101 of the two halves 10A and 10B are formed with grooves 102 corresponding to the hangers 20; then, an adhesive material 10C (see fig. 2) such as refractory mortar is applied to the opposing surfaces 101 of the two halves 10A and 10B to bond and fix the two halves 10A and 10B together to form the body 10 (in other words, the body 10 may include the half 10A, the half 10B, and the adhesive material 10C); with the hanger 20 sandwiched between the two halves 10A, 10B and partially disposed in the recess 102 and contacting the opposing face 101 or the adhesive material 10C on the opposing face 101. Since the hanger 20 is assembled to the body 10 after the half portions 10A, 10B of the body 10 are sintered and formed, and is not inserted into the body 10 during the sintering and forming process, the hanger 20 is not subjected to a high temperature during the sintering and forming process.

The plurality of metal wires 30 may be disposed in the body 10 and extend from the top portion 11 to the bottom portion 12, thereby increasing structural strength between the top portion 11 and the bottom portion 12, i.e., increasing structural strength in a vertical direction (height direction) of the body 10. Thus, when the body 10 is subjected to high temperature, the bottom portion 12 is not easily separated from the top portion 11, and is not easily broken in the vertical direction. The plurality of metal wires 30 may be inserted into the paste when the paste of the body 10 is formed; after the slurry is cured, the metal wire 30 can be embedded in the body 10. Preferably, the plurality of wires 30 may extend obliquely from the top 11 to the bottom 12, rather than vertically, so that the structural strength of the body 10 in the horizontal direction can also be increased.

In the present embodiment, the plurality of metal lines 30 includes two metal lines, i.e., a first metal line 31 and a second metal line 32, and the first metal line 31 and the second metal line 32 are staggered (as shown in fig. 2, viewed in a horizontal direction). The first metal line 31 extends from one corner of the top portion 11 to one corner of the bottom portion 12, and the second metal line 32 extends from the other corner of the top portion 11 to the other corner of the bottom portion 12. The first metal line 31 and the second metal line 32 may be separated in the horizontal direction without contacting, or the first metal line 31 and the second metal line 32 may contact only at the crossing portion. Thus, the body 10 is less likely to be broken in the vertical direction when subjected to high temperatures.

The plurality of metal wires 30 may be high temperature resistant metal wires, such as nichrome wires or ferrochrome alloy wires, and the suitable metal or alloy may be selected according to the application requirement. In addition, the plurality of metal wires 30 may be rod-shaped or bar-shaped (with a circular or rectangular cross section), and may be bent, wavy, spiral or bifurcated (not shown), so as to increase the contact area and the bonding force between the metal wires 30 and the body 10.

Referring to fig. 4 to 7, a kiln top hanging brick 1 according to another preferred embodiment of the present invention is proposed, which is different from the above at least in that:

as shown in fig. 4, the first metal lines 31 and the second metal lines 32 do not necessarily need to be staggered (viewed in the horizontal direction), for example, they are arranged in a V shape; as shown in FIG. 5, the hanger 20 may have a hook 22 for hooking to a steel frame (not shown); as shown in FIG. 6, the hanger 20 may be integrally formed with the top 11 of the body 10, i.e., a portion of the top 11 acts as the hanger 20 and the iron stand passes directly through the aperture 21 in the top 11; as shown in FIG. 7, the hanger 20 is integrally formed with the top 11 of the body 10, and the hanger 20 itself is shaped to be supported by a hob (not shown), for example, the hanger 20 has two lugs and the hob is located below the lugs.

In conclusion, the kiln top hanging brick provided by the utility model has better structural strength, is not easy to break due to high temperature in the kiln, prolongs the service life of the kiln top hanging brick and reduces the loss of the production process. On the other hand, the kiln top hanging brick can have multiple pores, thereby having better fire resistance and lighter weight.
