Abstract (en)

[origin: JPH02130388A] PURPOSE: To measure the temperature of melt accurately by locating both an opening and a thermosensor below the mirror surface of the melt when the thermosensor provided with a protective coating part plunges into the wall part of a melting trough through the opening. CONSTITUTION: A protective pipe 3 is dispose directly above the opening of a capillary cast passage 2 in a melt trough 1 while plunging into the wall part thereof through an opening 8. A thermosensor 3 is separated, at most 2 mm, from the passage 2 or the inner wall of the tunnel type melt trough 1. Consequently, gravity acts in addition to the pressure of gaseous atmosphere at the time of casting process. Since a capillary casting passage is employed, a material melted by surface tension is prevented, by gas pressure, from entering through the passage 2 during a melting process. Since the forward end part of the thermosensor 3 plunges into the melt, temperature of the melt can be measured accurately.
