Abstract
PURPOSE: To manufacture glass-lined material having very high corrosion resistance, by heating a frit coating layer from metal side of the material toward surface layer side.
CONSTITUTION: Muddy frit is applied to the inner and outer peripheral surface of a long sized pipe, and is preheated by a high frequency induction heating means to a temp. not higher than the melting temp. of the frit, and is then quickly heated to a temp. not lower than the melting temp. in order to calcine it. Hereby the frit layer is heated from the material side toward surface layer, so that the formation of pinholes and bubbles is prevented. For example, a frit coating layer 2 is formed on the inner and outer peripheral surfaces of the material metal 1. A pipe 3 is hung under a high frequency induction coil 4, having such an inner diameter that its inner surface makes a prescribed space with the outer surface of the pipe 3, and in such a position that the axial line of the heating coil 4 agrees with that of the pipe 3. An electric power supply E is put to work, and the pipe 3 is pulled up in the direction of (a) at a prescribed speed and is preheated by the coil 4a and is heated regularly by a coil 4b. Hereby generated water vapor and gas are released easily to the outside of the coating layer, hence lining layer of uniform quality is formed.
