曲りは先端部５ＩＩＢまでの部位で見ら九る。When this lance body is inserted into a measuring furnace, it is subjected to a large heat load and at the same time is subjected to a large amount of fII molten metal splashing and adhering. In conventional lances, the outer tube 1 of the measuring device body is melted by molten metal, and the cooling water inside f'L flows out, making it unusable and significantly shortening the life of the device. The lance body bends due to uneven heat load, making it impossible to mount the measuring instrument. I can't see it.

It is sufficient to increase the speed to 1 all/le or more than the normal 3 to 5 s/s+ect 6 s/see. Note that when the flow rate exceeds 1511/I@, the pressure loss increases in proportion to the square of the velocity.
When the temperature exceeds a/s@e, the pressure loss becomes so large that it is practically unusable. Furthermore, below 5''l/j@e, this is a region where conventional problems occur.

の結果最適と考えられてい友。Here, it is easy to think of increasing the amount of cooling water as one method, but since it increases the capacity of the entire cooling water equipment and the equipment cost increases, it is not practical, and it is not practical. A cooling water speed of 3 to 5 a/see is considered to be optimal after many actual operations.

る。Therefore, the inventors of the present invention have thought of increasing the cooling water speed more easily, that is, by reducing the area of the cooling water flow path up to the melted portion and the bent portion of the outer tube 1 of the main body.

Cooling water is flowing between the pipe 3 and the pipe 3.

キングである。Water supply and drainage to the lance are carried out via a flexible hose 5.6t for water supply and drainage connected to f'L7. Reference numeral 7 is a sling for replacing the main body, 8 and 9 are fittings to prevent water leakage from the main body and each of the flexible hoses 5 and 6, and 10 is a #1 foot device made of molten metal. The 7tll is a gland fitting that prevents water from leaking from the main unit.

後、排水用フレキシブルホース６へと流すものである。That is, the cooling water supplied by the flexible water supply hose 5 makes a U-turn at the tip A of the main body and flows into the drainage channel.
2, when entering the part where the flow path area is conventionally reduced from p 1- to 1, the flow velocity suddenly increases from 6 m/j@c to 15 s/s@e, and the outer tube l The inner surface of the drain is forcibly cooled, the heat from the outside is absorbed, and after cooling, the water is discharged to the flexible hose 6 for drainage.

を速くすることが可能となる。By the way, the attachment of the spiral plate 12 to the middle tube 2 in the present invention is as shown in FIG.
It is easy to install by welding, and this method allows the flow area between the inner diameter of the outer tube 1 and the outer diameter of the middle tube 2 to be smaller than the conventional flow path area. This makes it possible to increase the cooling water speed.

It has the extremely beneficial advantage of extending the service life.
