摘要： PURPOSE:To stably produce a cast ingot, which is difficult to develop surface defect, by uniformly flowing out lubricating oil from small gap extending to horizontal direction between outer circumferential face at front side part of the orifice plate and inner circumferential face of a mold onto the whole circumferential face of the ingot. CONSTITUTION:Annular lubricating oil passage 5 is arranged at the part of the mold 3 in contact with the orifice plate 2. The lubricating oil flowing through radial grooves 6 from the above passage 5 arrives to the outer circumferential face at the front side part of the orifice plate 2 facing to the mold and the course is converted to advancing direction of the casting ingot 9. After spreading the lubricating oil in the gap 7 between the inner circumferential face of the mold 3 and the outer surface of the orifice plate 2 almost uniformly, this is allowed to flow out on the outer surface of the casting ingot 9. As the outer surface of the ingot 9 is lubricated almost uniformly, the casting ingot without any roughening and burning on the casting surface can be produced.

摘要： PURPOSE:To smoothen casting by closing hermetically a recessed part arranged surrounding outlet of an orifice with a starting block, positioning the starting pin out of the outlet of the orifice and causing molten metal to flow into a mold. CONSTITUTION:The recessed part 8 surrounding the outlet of the orifice 7 at the mold 3 side of the orifice plate 2 arranged between molten metal discharging hole in a tundish 1 and the mold 3 is arranged, and by abutting the starting block 4 on the whole surface of the orifice plate 2, the recessed part is closed hermetically. After positioning the starting pin 5 at the position out of the orifice, the molten metal is allowed to flow in through the orifice 7 from the tundish 1 and successively, the starting block 4 is drawn out from the mold 3 together with the solidified molten metal. By this method, the casting can be stably and easily executed without developing any breakout.

摘要： PURPOSE:To leave exactly impurities on the inside wall of a container, and to obtain an extruded section by constituting so that the outside diameter of the tip part of a die block is smaller than the inside diameter of a billet loading hole of the container. CONSTITUTION:A stem 2 is extruded without installing a clean-out ring 4, and a section is extruded through a die block 3. The outside diameter of the tip part of the die block 3 is made smaller than the inside diameter of a billet loading hole of a container 1, and also the billet loading hole is expanded a little by an extruding pressure. Accordingly, a clearance is generated between the die block 3 and the inside wall of the container 1, and a billet skin part (a) is left in said clearance. Also, before loading the next billet B, a projecting edge part is formed by combining the clean-out ring 4 in the inside of a stepped part of the die block 3. The billet skin part (a) adhering to the inside wall surface of the container 1 is scraped and removed by this projecting edge part.

摘要： PURPOSE:To prevent bending downward of a tip part of an ingot by arranging a recessed part at the tip part of a starting block shielding a mold, fitting a starting pin at the base bottom part thereof and drawing out this together with the tip part of a solidified part. CONSTITUTION:Molten metal is introduced into the cooled mold 3 from a tundish 1 through an orifice plate 2 and filled up into the recessed part 6-1 of starting block 6. The molten metal is cooled and solidified to form the tip part of ingot 7 integrated with the starting pin 8. Successively, the starting block 6 is drawn out to start the casting. Since the recessed part 6-1 is formed at the rear end part of starting block 6 and the ingot is drawn out while surely supporting with the peripheral face thereof, the bending downward is not generated.

摘要： PURPOSE:To obtain a titled device that cleans the inner wall and eliminates cleaning process by providing a projected edge having elastic restoring force on the outer periphery of a die block and contracting it when extruding and bringing it close to the inner wall of a container when returning in indirect extrusion of a metallic billet. CONSTITUTION:An umbrella-shaped projected edge 4 having elastic restoring force is provided on the outer periphery of a die block 3. When indirectly extruding a billet B in the container 1, the projected edge 4 contracts and forms an outer layer (a) of the billet in the pipe. When returning, the projected edge 4 is opened and brought close to the inner wall of the container 1 and cleans the inner wall face. Accordingly, the succeeding billet B can be inserted to continue indirect extrusion.

摘要： PURPOSE:To precisely and quickly detect the breakout with a simple device by connecting each one end of plural ropes under stretching condition to a tension detecting instrument and detecting the breakout from the change in the tension in the rope caused by the falling molten metal. CONSTITUTION:When the molten metal 1 projecting from a mold 4 drops due to occurrence of the breakout, the molten metal is stuck to at least one piece of the rope in plural ropes 12, 12... set at the lower part, and this rope 12 is melted and cut. By this cutting, the detecting end part in the tension detecting instrument 13 connected to the one end of the cut rope 12 is displaced, and this displacing signal is transmitted to a control device 8. At the time of receiving this signal in the control device 8, comparison-operation is executed between the detected value and the set value, and after confirmation of the breakout, a control signal is transmitted to a molten metal shut-off device 7, and by working a cylinder, a tip shut-off part in the molten metal shut-off device 7 is dipped into a trough 2 to stop the flow of the molten metal 1.

摘要： PURPOSE:To continuously form the high quality ingot product by interposing an annular flow straightening means at the connecting part of an annular cooling water chamber in a mold and a cooling water injecting part opened to an inner peripheral face in the mold. CONSTITUTION:The mold 3 is fitted at the front face side of a tundish 1 through an orifice plate 2 to form this horizontal continuous casting device. The annular cooling water chamber 3-3 connected with a cooling water pouring hole 3-6, is provided on the inside of the mold 3. The cooling water injecting part 3-4 communicated with the cooling water chamber 3-3 and having tip opening part 3-5 opened as annular on the inner peripheral face in the mold 3 is provided. The annular flow straightening means 5 for feeding to the cooling water injecting part 3-4 by straightening the flow of cooling water in the cooling water chamber 3-3, is interposed at the connecting part of the cooling water chamber 3-3 and the cooling water injecting part 3-4. By this method, the whole peripheral surface of cast ingot can be uniformly cooled.
