摘要： PURPOSE:To facilitate taking out of a solidified sample and to prevent the generation of cavities and pinholes in the solidified sample by forming a reducing path consisting of a cylindrical boss made of a nonmetallic material having small thermal conductivity to a partition wall between an inflow chamber and a sampling chamber. CONSTITUTION:A container 3 has the inflow chamber 6 facing an inflow port 4 opened to a side part and the sampling chamber 8 communicated with the chamber 6 via the reducing path 7 disposed below the inflow chamber. A barrier part 9 is projected to the molten metal flow passage from the inflow port 4 to the sampling chamber 8. The reducing path 7 is formed of the cylindrical boss 11 provided on the partition wall 10 which partitions the inflow chamber 6 and the sampling chamber 8. The tip of the boss 11 is positioned upper than the inside base of the port wall of a nozzle member 4a forming the inflow part 4. The excess molten metal in the inflow chamber 6 flows out of the inflow port 4 and the excess molten metal does not remain in the inflow chamber 6 if the container is pulled up after the molten metal is sampled. The molten metal is filled into the sampling chamber 8 and the reducing path 7 while said metal is slowly cooled if the boss 11 is formed of the nonmetallic material having the small thermal conductivity. The generation of the cavities and pinholes in the solidified sample is thus obviated.

摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus for sampling a molten metal specimen in a vacuum refining furnace which enables sampling of a specimen from molten metal under the boiling process and moreover, obtaining of a coagulation sample without blowhole while the operation of the vacuum refining furnace is continued. SOLUTION: In a specimen sampling method in which a specimen is trapped from molten metal under the boiling in a furnace kept in high vacuum and then, introduced into a sample chamber while being coagulated within the sample chamber, the molten metal specimen 4a trapped in the furnace is retained being molten in a standby chamber 4a by a specified time enough to settle down the boiling. During the retention in the chamber, a gas is bled out of the specimen 4a while a sample chamber decompressing process is performed for reducing the pressure in the sample chamber 14 within the furnace. Then, the specimen via the gas bleeding process is introduced into the sample chamber 14 subjected to the sample chamber decompressing process and worked to be coagulated in the sample chamber 14.

摘要： PURPOSE:To prevent the generation of defective points such as cavities and pinholes in a solidified sample by forming a part of a flow passage of a nonmetallic material having small thermal conductivity and delineating a sampling chamber by a nonmetallic material having small thermal conductivity and a chiller. CONSTITUTION:A container 3 has an inflow chamber 6 facing an inflow port 4 and the sampling chamber 8 which is disposed below said chamber and is communicated with the inflow chamber 6 via a reducing path 7. A barrier part 9 is projected to the proper point in the molten metal flow passage from the inflow port 4 to the sampling chamber 8. The reducing path 7 is formed of a cylindrical boss 11 provided to a partition wall 10 which partitions the inflow chamber 6 and the sampling chamber 8. This path and the inflow chamber 6 are formed of the nonmetallic material having the small thermal conductivity. The sampling chamber 8 is delineated by the bottom of the partition wall 10 consisting of the nonmetallic material and the recess 13a of the chiller 13 having the large heat conductivity. The molten metal flowing into the container collides against the barrier wall 9 and after the molten metal is stirred by the collision, the molten metal flows into the sampling chamber 8 and, therefore, the molten metal is homogeneously deoxidized. Since the molten metal advances into the sampling chamber 8 under slow cooling, the generation of the cavities and pinholes in the solidified sample is obviated.

摘要： PURPOSE:To prevent the deposition of a base metal in the connecting part of a sub- lance and the probe by constituting a gas generating means consisting of a material which generate a gas at the time of a high temp. on the outer peripheral surface of a connecting cylinder and solidifying a molten metal when the molten metal sticks. CONSTITUTION:The connecting cylinder 17 is constituted of the gas generating means 19 which consists of the material to generate the gas at the time of the high temp., a metal solidifying means 20 which consists of a metallic material to solidify the molten metal when the molten metal sticks, and a sealing means 40 which crushes the above-mentioned metallic material by the pressing force of a shoulder part 7 of the sub-lance and comes into tight contact with the shoulder part 7 of the sub-lance. The gas is generated from the gas generating means 19 of the connecting cylinder 17 when the probe 5 is inserted into a converter by the syb-lance 4. The fine particles M1 of the molten metal suspending (spitting) in the converter 2 are bounded and retreated from the outer periphery of the connecting cylinder 17 by the generation of this gas. The fine grains M1 of the molten metal are, therefore, prevented from sticking to the connecting cylinder 17.

摘要： PURPOSE:To adequately cool the sample flowing into a sample drawing vessel without loading a special cooling member into the vessel by discretely constituting the sample drawing vessel and block and precooling the sample flowing through the block into the vessel. CONSTITUTION:A sample drawing device 1 is inserted from the top end into a refining furnace and arrives at the inside of the molten steel, then a burnable sheet 23 burns away and the molten steel or the like flows into the block 2 through the inflow port 11 thereof so as to flow through a flow passage 12 into the sample drawing vessel 3. The molten steel or the like is procooled in the passage 12 and after foreign matter is removed therefrom, the molten steel fills the inside of the vessel 3 where the molten steel is quickly cooled and solidified to form the sample having the uniform quality. The molten steel or the like admitted therein through the port 11 in succession thereto is also solidified in the passage 12 and is united integrally with the solidified sample in the vessel 3 via a communicating part 12a. The solidified metal in the part 12a has a thin-walled shape and is easily breakable so that the sample can be easily disconnected from the solidified metal in the passage 12. On the other hand, a temp. sensor 22 is isolated via a partition wall 14 and is therefore protected against the impact and high heat of the molten steel.
