INDUSTRIAL APPLICATION FIELD The present invention relates to linings for molten metal containers, etc., which are made by sandwiching a flexible and compressible refractory packing material between refractory members. BACKGROUND ART Conventionally, refractory mortar has been used between lining refractory members for lining molten metal containers and the like. Problems to be Solved by the Invention However, applying fireproof mortar is labor-intensive and takes a long time to dry and bond. The high temperature during use causes seizure between refractory members or seizure between metal and refractory members, so if some of the members are damaged during use, it is difficult to replace only the damaged members. Furthermore, the mortar portions of the joints of structures that are joined using refractory mortar have poor resistance to molten steel and slag, which often causes steel leakage accidents. In other words, the problems of joining using the conventional mortar method, as is well known to those skilled in the art, are as follows: (1) construction is difficult and workability is poor; (2) leakage occurs due to the corrosion resistance of refractory mortar and the occurrence of cracks. (3) Since refractory mortar with good airtightness (sinterability) is used, there is a lot of residual steel attached to the lining surface after use, making removal work complicated. Means for Solving the Problems The inventors of the present invention have successfully developed the present invention as a result of various studies to solve the above-mentioned problems.
The structure of the present invention is as specified in the claims, and in the present invention, a refractory packing having flexibility and shrinkability under pressure is provided between refractory members.
By using it in areas where conventional mortar is used,
It is extremely easy to assemble the mounting components, and there is no need for drying.
It is effective. As the fire-resistant packing material having flexibility and pressure shrinkability used in the present invention, for example,
100 weight of both inorganic refractory powder and inorganic fiber, both inorganic refractory powder and organic fiber, or the three of inorganic refractory powder, inorganic fiber, and organic fiber described in Publication No. 55-7514 3-50 parts by weight of a liquid binder, i.e., a synthetic resin emulsion or/and rubber latex, which is flexible after drying as a binder, is added as the main raw material. The fireproof board can be cut or molded according to the required joints. Alternatively, it is also possible to use a flexible fireproof sheet made by adding a foaming agent to the fireproof board composition and foaming it to provide compressibility under pressure. The fire-resistant packing used in the present invention can be used by sandwiching or fitting the above-mentioned materials as they are into the joint, but in order to improve workability, pressure-sensitive adhesive may be applied to the construction surface before use. be able to. For example, by lining the construction surface with a pressure-sensitive adhesive made of a mixture of fire-resistant material fine powder, an inorganic binder, and a synthetic resin or rubber-based adhesive, and pasting release paper, assembly workability can be further improved. Improved. The preferred conditions for the fire-resistant packing used in the present invention are as follows: (1) The thickness of the fire-resistant packing is preferably 2 to 20 mm. (2) The compressibility of the fire-resistant packing is determined by the installation pressure. (the pressure tightened by the fitting alloy of conventional bolts and nuts) and thermal stress.
80% is desirable. However, it can be selected as appropriate depending on the shape, size, material properties, and other operating conditions of the refractory at the site of use. Several specific examples of the present invention will be explained based on the accompanying drawings. However, the present invention is not limited to these specific examples, and changes and modifications within the gist of the present invention are included in the present invention. FIG. 1 is a sectional view showing an example in which the present invention is applied to a ladle, and is an example in which a refractory packing 2 is sandwiched between each refractory brick 1 to perform lining construction. is a permanent brick,

When constructing refractory brick linings for hot metal ladle, molten steel ladle, etc., a flexible and pressure-shrinkable refractory packing material with a predetermined thickness and the same shape as the refractory brick surface is sandwiched between the refractory bricks, thereby eliminating the need for conventional joint mortar. It is possible to save labor in furnace construction work, and it is also possible to uniformly absorb the thermal expansion of the refractory bricks, thereby preventing the refractory bricks from cracking or collapsing due to thermal stress. FIG. 2 is a cross-sectional view of the fire-resistant packing material 2 to which the pressure-sensitive adhesive 3 is applied, as described above.

Effects of the Invention With the structure of the present invention, the following effects can be achieved: (1) By using the packing used in the present invention in the conventional mortar-used portion, it is extremely easy to assemble the mounting member. (2) Does not require a drying process unlike conventional mortar. (3) There is no seizure between refractory members during use. (4) Uniform absorption of the thermal expansion of refractory bricks is possible. (5) It can prevent cracking and collapse of refractory bricks due to thermal stress.
