[Industrial Field of Application] The present invention relates to a powder material for flame spraying used for repairing furnaces, particularly coke ovens. [Prior Art] Currently, thermal spraying materials generally used for repairing coke ovens include SiO 2 -based refractory materials, Al 2 O 3 , Fe, etc., as described in Japanese Patent Publication No. 58-33189. Some contain 2 O 3 , CaO, MgO, Na 2 O, K 2 O, etc. After thermal spraying, this thermal spray material becomes glassy, which follows the expansion and contraction of the silica bricks that form the walls of the coke oven due to thermal changes when taking coke in and out, preventing cracks from forming. It has the characteristics of [Problem to be solved by the invention] However, during long-term use of such a glassy thermal spray body, glass crystallization progresses and the volume changes, so it is particularly difficult to spray over a wide area. When a body is formed, cracks occur and the brick is easily peeled off from the adhesive surface with the brick, resulting in a problem that satisfactory durability cannot be obtained. The problem to be solved by the present invention is to eliminate the disadvantage of short life due to crystallization when the high-silica sprayed material forming the above-mentioned glassy sprayed body is used for repairing a kiln. [Means for Solving the Problems] The present invention has been completed based on the basic concept that the occurrence of defects due to glassy crystallization can be eliminated by controlling the progress of crystallization. be. That is, as a result of investigating the relationship between the elapsed time immediately after spraying and the crystallization rate of the sprayed material obtained by spraying the sprayed material onto a silica brick wall maintained at 1000℃ using a flame spraying device, it was found that This is based on the knowledge that in the case of a thermally sprayed body with a crystallization rate of 60% or more, the repair body will not be adversely affected even by the subsequent progress of crystallization. Specifically, the thermal spray material of the present invention has SiO 2 93.9~
99.6% by weight, Al 2 O 3 1.5% by weight or less, CaO2.0% by weight
It is composed of 1.0% by weight or less of Fe 2 O 3 and 0.4 to 2% by weight of Na 2 O, and has the property of crystallizing immediately after thermal spraying. In the present invention, SiO 2 is blended to make the repaired body homogeneous with the lining brick of the kiln, and in order to obtain a crystallization rate of 60% or more,
93.9% by weight is required. However, if it exceeds 99.6% by weight, only a crystallization ratio of 60% or less can be obtained. Therefore, the blending amount of SiO 2 needs to be 93.9% by weight or more and 99.6% by weight or less. Al 2 O 3 and CaO are necessary in order to make the repaired body formed similar in composition to the silica bricks used as the lining of kilns. However, in the case of Al 2 O 3 1.5% by weight in the total formulation,
Moreover, in the case of CaO, if it exceeds 2.0% by weight, it tends to vitrify, resulting in the disadvantage that only a crystalline product with a crystallinity of 60% or less can be obtained immediately after thermal spraying. Further, Fe 2 O 3 needs to be 1.0% by weight or less in order to increase the crystallization rate of the sprayed body to 60% or more. Furthermore, although Na 2 O is essential for making the constructed body glassy, if it exceeds 2% by weight, the fire resistance of the sprayed body will be low and it will become too soft, causing problems during construction. If the content of 2 O is less than 0.4% by weight, the flame-sprayed material will have too high a fire resistance and will be difficult to work with, so it should be in the range of 0.4 to 2% by weight based on the total composition. The thermal spray material of the present invention may be used by mixing the above components and adjusting the particle size so that the total particle size is 0.21 mm or less. In addition, starting materials such as fused silica, silica sand, silicate ore, alumina, sodium silicate, and silica brick scraps may be prepared in any combination and heat treated to uniformly mix these raw material powders. Preferable for adjusting within the range. The above-mentioned heat treatment temperature needs to be 500° C. or higher in order to evaporate the crystallization water of the raw material powders and to bond and sinter the raw material powders together. however,
1000 to prevent Na 2 O from evaporating too much.
Must be less than ℃. For the above reasons, the heat treatment temperature is
It should be within the range of 500℃ or more and less than 1000℃. The present invention will be explained below with reference to Examples. [Example] A regular type of silica brick (115 x 230 x 60 mm) was placed in a furnace maintained at 1000°C, and a thermal spraying material having the chemical composition listed in Table 1 was sprayed onto each silica brick. Thermal spraying conditions are: LPG: 15Nm 3 /Hr, O 2 : 70N
m 3 /Hr, thermal spray powder amount: 50Kg/Hr, burner movement speed: 4m/min, burner and brick wall surface (115×
The distance between the two 230 mm surfaces was 300 mm, the spraying time was approximately 20 seconds, and the thickness of the sprayed layer per silica brick average surface was approximately 20 mm near the center. After spraying one type of sprayed material onto six regular silica bricks to form the above sprayed layer,
The first sheet was taken out of the furnace 1 minute after thermal spraying, the second sheet was taken out after 5 minutes after thermal spraying, and the third sheet was rapidly cooled after 10 minutes after thermal spraying, and the crystallization rate of the thermally sprayed bodies was measured.
The remaining three normal type sheets were transferred to a furnace at a higher temperature of 1300℃ within 1 hour after spraying, and changes in the sprayed material were examined after 1, 2, and 3 months, and cracks between the sprayed material and the bricks were investigated. The presence or absence of peeling was examined. The crystallization rate is measured from the area intensity ratio of X-rays and is expressed as the total amount of cristobalite and tridymite. Based on the test results shown in Table 1, an actual furnace test was conducted in an actual coke oven. The thermal spraying materials used were the results of tests No. 8, No. 9, and No. 10 in Table 1.
Peeling occurred in No. 8 in the first year, in No. 9 in the 6th month, and in No. 10 it remained in good condition even after one and a half years. The scope of the present invention is Nos. 1, 2, 4, and 10 to 12. In No. 1, the crystallization rate does not reach 60% or higher until 10 minutes have elapsed, but given that cracks do not appear even after 3 months, the crystallization rate of No. 1 does not reach 60% or higher immediately after thermal spraying. It can be said that it has

The thermal spraying material of the present invention has a crystallization rate of 60% immediately after thermal spraying.
Since the above thermal sprayed body is formed, even if thermal spraying is performed over a wide area, the volumetric shrinkage accompanying the transition from the glass phase to the crystalline phase is small, and cracks that may lead to peeling do not occur. In addition, since it is high in silica and highly crystalline, it exhibits almost the same thermal expansion as silica bricks used in coke ovens, etc., so it is resistant to repeated changes in heat due to the loading and unloading of coke, and does not cause adverse effects due to aging. Therefore, it is possible to obtain a thermal sprayed repair body that can withstand long-term use.
