Field of the Invention The present invention relates to a method for constructing glass linings for glass-lined equipment made of stainless steel sheets or cast metals that can withstand severe conditions of use in the chemical industry, pharmaceutical industry, food industry, etc.

なされてきている。BACKGROUND OF THE INVENTION In order for the base material to firmly adhere to the base metal in glass lining firing, it must be a metal that can be oxidized. Since stainless steel metal is non-oxidizing, conventionally, stainless steel glass lining is pre-treated by chemically treating the stainless steel surface with acid or physically sandblasting to roughen it to improve the adhesion between it and the underlayment. Attempts have been made.

There is a large difference in the linear thermal expansion coefficient between the stainless steel base and the glass lining layer, and residual compressive stress due to the difference in cooling shrinkage after the firing process becomes large, causing shear stress to occur from the stainless steel base to the glass lining layer, which often causes the glass lining to peel off. .

見出し本発明を完成するに至った。[Means for Solving the Problems] In order to achieve the above-mentioned object, the present inventors conducted extensive research on the thermal spraying material, the thermal spray film thickness, and the glass lining layer thickness ratio, and as a result, the total glass lining thickness was determined to be 600 to 2500 μm. They found that by setting the ratio of the thermal spraying layer thickness to the glass lining layer thickness within the range of 1:10 to 200, a glass lining structure with excellent adhesion and glass lining releasability could be obtained, and the present invention was completed.

By thermal spraying the Fe-Cr alloy, the disadvantage of the glass layer peeling off due to the difference in cooling shrinkage between the glass lining layer and the metal after firing the glass lining layer is eliminated, and sufficient adhesion strength can be obtained.

Great anti-peeling effect. All glass lining thickness is JI
The thickness of the sprayed layer is 600 to 2500 μm determined by the S standard, and the thickness of the sprayed layer can be 10 to 250 μm, preferably 10 to 100 μm. If the sprayed layer is less than 10 μm, the residual stress relaxation effect will be poor, and if it exceeds 250 μm, there will be a disadvantage that gas will be released from the sprayed laminated structure during firing of the glass lining.

Furthermore, if the thickness of the thermal sprayed layer is too thick relative to the total glass lining thickness, such as less than 1:10, pores associated with the laminated structure in the thermal sprayed layer will become a problem, and glass will enter the pores in the thermal sprayed layer during the glass lining firing process. It cannot penetrate and remains as a void, which causes a decrease in the strength of the glass lining structure and has the disadvantage of causing the glass lining to peel off.

On each of the thin steel plates, the powder B powder shown in Table 1 was dry-sieved to a glass thickness of 0.3 mm using an 80-mesh sieve, and after baking at 840°C for 10 minutes, the apparatus shown in Figure 1 was applied.

After that, samples with no peeling were immersed in water at 15° C. for 15 minutes. After that, a cold test of ΔT85°C was carried out three times by immersing the glass in hot water of 100°C for 15 minutes, and the glass lining was left to stand for 1 day, and the presence or absence of peeling of the glass lining was examined.

With this ratio, there is no cracking in the glass lining layer.
The results showed very good results.

Castings have particularly large residual stress after firing and poor adhesion, resulting in peeling of the glass lining. There are problems that can easily cause problems. In Example 3, a study was conducted to examine the effect of the thermal spraying treatment of the present invention on a stainless steel casting base. The stainless steel casting sample is 30 mm of SCS-14 material equivalent to SUS-316.
From the dimensions of x35mm x 300mm to 30mm x 35m
Cut into 30mm x 30mm pieces and apply Ni and Cr metal spraying treatment to 30mm x 30mm.

ニング構造体を提供することができる。Effects of the Invention The glass lining construction method of the present invention involves thermally spraying a metal or alloy onto the surface of a stainless steel base material, and then heat-treating the glass lining. Since the ratio of the thermal spraying layer thickness to the glass lining layer thickness is within the range of 1:10 to 200,
A glass lining structure with excellent adhesion and glass lining releasability can be provided.
