Abstract
A molten metal probe which is dipped into molten metal and thereafter pulled up therefrom and which is capable of preferably providing solidification temperature data of the molten metal and providing a solidified sample. A probe main body includes an introductory path facing a flow inlet formed at a side portion thereof, a communicating path and a sampling path branched respectively upwardly and downwardly from the introductory path, a temperature measuring chamber communicated with the communicating path extended upwardly, a sampling chamber communicated with the sampling path extended downwardly, and a temperature sensor facing the temperature measuring chamber.
Claims13
A molten metal probe which is dipped in molten metal and is thereafter pulled up therefrom comprising a probe main body (1), a flow inlet (3) provided at a side portion of said probe main body for flowing in the molten metal, a temperature measuring chamber (10) and a sampling chamber (25) separately provided in said probe main body for solidifying the molten metal flowed therein respectively, and a temperature sensor (22) arranged in said temperature measuring chamber (10);
- wherein
- runners branching upwardly and downwardly from an introductory path (8) opened to face the flow inlet (3) are provided, a sampling path (27) constituted by the downward runner is communicated with the sampling chamber (25) and a communicating path (9) constituted by the runner extended upwardly is communicated with an upper portion of the temperature measuring chamber (10).
A molten metal probe which is dipped in molten metal and is thereafter pulled up therefrom comprising a probe main body (1), a flow inlet (3) provided at a side portion of said probe main body for flowing in the molten metal, a temperature measuring chamber (10) and a sampling chamber (25) separately provided in said probe main body for solidifying the molten metal flowed therein respectively, and a temperature sensor (22) arranged in said temperature measuring chamber (10);
- further comprising:
- a plug (6) internally mounted to a front end portion of the probe main body and a unit body (7) internally mounted to the probe main body in a state in which the unit body (7) is connected to the plug;
- wherein
- the plug (6) and the unit body (7) are separately formed and are molded in blocks respectively by a collapsible fire resistant material;
- the unit body (7) includes an introductory path (8) opened to face the flow inlet (3), a communicating path (9) extended upwardly from the introductory path, the temperature measuring chamber (10) extended downwardly by being turned back from the communicating path, a guide path (11) extended downwardly from the introductory path (8) and a free space (13) formed by expanding a lower portion of the guide path and opened to a lower face of the unit body (7);
- the plug (6) includes a holding recess (18) opposed to the free space (13);
- and
- a sampling vessel (23) constituting the sampling chamber (25) provides a vessel main body (23a) made of metal with a guide pipe (26) extended therefrom and inserted into the guide path (11), an upper portion of the vessel main body (23a) is loosely inserted to the free space (13) and a lower portion of the vessel main body (23a) is fitted to the holding recess (18).
