〔産業上の利用分野〕
本発明は、内装又は外装用資材として使用される金属タ
イルを溶射によって製造する方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for producing metal tiles used as interior or exterior materials by thermal spraying.

陥が製品に生じ易いものであった。また、焼成のために
炉を使用するので、設備的な制約もあり、たとえば現場
で簡単に釉薬を施工することが困難であった。Traditional tiles are manufactured by applying a glaze to a base material and firing it in a furnace for a long time. Heating in this furnace
Cooling generates thermal stress in the base material, which tends to cause defects such as warping and deformation in the product. Furthermore, since a furnace is used for firing, there are equipment limitations, for example, making it difficult to easily apply glaze on site.
このような欠点を解消するものとして、本発明者等は、
溶射によってタイル基材の表面に釉薬層を焼き付ける方
法を開発し、これを特願昭６１−１４５０９０号として

変形等の欠陥が生じ難い。In order to eliminate such drawbacks, the present inventors
He developed a method of baking a glaze layer onto the surface of a tile base material by thermal spraying, and filed an application for this method as Japanese Patent Application No. 145090/1983. When using this method, the tile base material on which the glaze is baked is already fired. Since the firing temperature of the tile base material is higher than that of the glaze, even if the tile base material is sometimes heated during the glaze firing, defects such as warping and deformation are unlikely to occur in the base material.
溶射による場合、フレームがタイル基材の表面を部分的
に加熱しなから溶射が行われるため、タイル基材に温度
差が生じる。タイル基材が無機質又は耐火材を焼成した
ものであるとき、多少の温度差があっても、前述したよ
うに剛性が大きいため熱変形を起こすことが少ない。し
かし、この溶射法を金属製のタイル基材に適用すると、
その温度差によりタイル基材に反り、変形等が生じる。In the case of thermal spraying, thermal spraying is performed after the flame partially heats the surface of the tile base material, so a temperature difference occurs in the tile base material. When the tile base material is made of fired inorganic or refractory material, even if there is a slight temperature difference, thermal deformation is unlikely to occur because the tile base material has high rigidity as described above. However, when this thermal spraying method is applied to metal tile substrates,
The temperature difference causes warping, deformation, etc. in the tile base material.
その結果、得られた多数の溶射タイルを組み合わせて対
象物に貼り付けるとき、待にタイルの継目を揃えること
ができず、またタイルを貼った面に凹凸が生じることに
なる。As a result, when a large number of sprayed tiles are combined and pasted onto an object, the joints of the tiles cannot be aligned, and the surface to which the tiles are pasted becomes uneven.
そこで、本発明は、釉薬を溶射するときに受ける熱応力
を小さくし、熱変形の少ない金属タイルを製造すること
を目的とする。Therefore, an object of the present invention is to reduce the thermal stress received when thermally spraying a glaze, and to manufacture metal tiles with less thermal deformation.
本発明の金属タイルの製造方法は、その目的を達成する
ため、金属製のタイル基材に釉薬を溶射するに先立って
、溶射時に加熱される前記タイル基材の温度をＴ℃とす
るとき、前記タイル基材の全体を（Ｔ−２００＞℃以上
の温度に均一に予熱することを特徴とする。In order to achieve the object, the method for manufacturing a metal tile of the present invention includes, before spraying a glaze onto a metal tile base material, when the temperature of the tile base material heated during spraying is T°C. The method is characterized in that the entire tile base material is uniformly preheated to a temperature of (T-200>°C or higher).
金属製のタイル基材を予熱する方法としては、タイル基
材自体を抵抗体とした通電加熱、タイル基材の背面に配

用される。Methods for preheating metal tile base materials include electrical heating using the tile base material itself as a resistor, heating with a radiant heater placed on the back of the tile base, and radiation heating placed on the back of the tile base. Indirect heating, such as heating a heating plate with gas, is used.
以下、図面を参照しながら、実施例により本発明の特徴
を具体的に説明する。Hereinafter, the features of the present invention will be specifically explained using examples with reference to the drawings.
一第１実施例−
第１図は、通電加熱方式を採用した本発明の第１実施例
を説明する図である。1. First Embodiment - FIG. 1 is a diagram illustrating a first embodiment of the present invention which employs an electrical heating method.

で溶射バーナ５によって釉薬が溶射される。A metal tile base material 1 to be preheated is placed on a machine base 3 to which a fireproof heat insulating material 2 such as asbestos is attached. Conductive wires 4a and 4b for electrical heating are attached to both ends of the tile base material 1.
and energize the tile base material 1 through the conductive wires 4a and 4b. By this energization, the entire tile base material 1 is preheated uniformly. The preheated tile base material 1 is then thermally sprayed with glaze by a thermal spray burner 5.

基材１として一般に使用されている普通鋼を使用した。FIG. 2 is a graph showing the influence of the preheating temperature of the tile base material 1 preheated in this way on the deformation of the tile base material 1 caused by heating during thermal spraying. Note that common steel, which is commonly used, was used as the tile base material 1.
そして、電圧５０Ｖ。And the voltage is 50V.
電流２００ＯＡの条件でこのタイル基材Ｉに通電するこ
とにより、タイル基材ｌを均一に予熱した。このとき、
タイル基材１の温度分布は、最高温度部と最低温度部と
の温度差が２℃以下と僅かなものであった。このように
して予熱されたタイル基材１に対し、融点が８００℃の
釉薬を用い、これを温度８００〜１０００℃で溶射した
。また、釉薬が溶射された後のタイル基材１の変形量を
マノメータで測定した結果を第２図に示す。The tile base material I was uniformly preheated by applying electricity to the tile base material I under the condition of a current of 200 OA. At this time,
The temperature distribution of the tile base material 1 had a slight temperature difference of 2° C. or less between the highest temperature part and the lowest temperature part. A glaze having a melting point of 800°C was thermally sprayed onto the tile base material 1 thus preheated at a temperature of 800 to 1000°C. In addition, FIG. 2 shows the results of measuring the amount of deformation of the tile base material 1 after the glaze was thermally sprayed using a manometer.

タイル基材１を変形させる原因となる熱応力が軽減され
るためである。As is clear from Fig. 2, the temperature difference between the preheating temperature t and the temperature T (800°C) of the tile base material 1 during thermal spraying is 20°C.
When the temperature is 0° C. or lower, the amount of deformation of the obtained thermal sprayed tile is reduced. This is because as the temperature difference T-t decreases, the temperature deviation that occurs between each tile base material 1 during thermal spraying becomes smaller.
This is because the thermal stress that causes the tile base material 1 to deform is reduced.
これに対して、温度差Ｔ−ｔが２００℃を越えるように
なると、溶射時に大きな熱応力が発生し、タイル基材１
が大きく変形する。On the other hand, when the temperature difference T-t exceeds 200°C, large thermal stress occurs during thermal spraying, and the tile base material
is greatly deformed.

A tile base material 1 is placed on the tile base material 1, and heat generated by an electric heater 32 is radiated to the back surface of the tile base material 1. The shorter the distance from the electric heater 32 to the back surface of the tile base material 1, the better the heating efficiency. Furthermore, when a surface layer such as a stainless steel plate with high reflectivity is attached to the surface of the machine base 3 on which the electric heater 32 is arranged, an improvement in heating efficiency can be seen.

タイル基材Ｉを均一に予熱した。The coppillite tile base material 1 was made red hot by passing a current of 200 OA at a voltage of 50 V through a nichrome wire, and then the coppillite tile base material I was uniformly preheated through a stainless steel plate.
次いで、溶射バーナ５によって釉薬をタイル基材１に溶

It turned out to be effective.

is opened, and fuel gas and oxygen gas are blown into the space of the recess 41. The heat generated by combustion within the recess 41 is transmitted to the radiant heating plate 43, and the tile base material 1 is preheated via the radiant heating plate 43. Note that the combustion exhaust gas is disposed of outside via the exhaust pipe 44.

３としては、アルミナ質のセラッミクス板やステンレス
鋼板等が使用される。This indirect heating method was adopted because if the tile base material 1 is directly heated by a flame of combustion gas, local temperature rise of the tile base material 1 is unavoidable. That is, by burning the fuel gas from the gas blowing channel 42 in the recess 41 and transmitting the combustion heat to the radiant heating plate 43, it is possible to perform homogeneous heat transfer to the entire surface of the tile base material 1. can. As a result, the temperature difference in each part of the preheated tile base material 1 becomes small. This radiant heating plate 4
As the material 3, an alumina ceramic plate, a stainless steel plate, or the like is used.

る。In addition, in FIGS. 1 to 4, it is shown that the tile base material 1 is placed horizontally and preheated. However, it goes without saying that the present invention is not limited to this. For example, the tile substrate 1 can also be placed vertically and preheated by similar means. It is also possible to thermally spray the glaze at a relatively high temperature to the vertically arranged tile base material 1 to form a rhytid glaze layer on the surface of the tile base material 1.

る。As explained above, according to the present invention, the metal tile base material onto which the glaze is thermally sprayed is heated to a predetermined temperature or higher in advance so as to reduce the temperature difference that occurs in the tile base material during thermal spraying, and Each part of the base material is preheated uniformly. Therefore, the thermal stress generated in the tile base material during thermal spraying is reduced, and the occurrence of defects such as warping and deformation in the tile base material after the glaze is thermally sprayed is suppressed. In this way, according to the invention, metal tiles with excellent shape properties are produced.
