摘要： PURPOSE:To improve the surface characteristic of a product and the production efficiency by disposing a sealing cover which covers an inlet side part and pouring spout for a molten metal and supplying an inert gas in a liquid state into the cover. CONSTITUTION:The sealing cover 8 is provided so as to cover the molten metal inlet side part and pouring spout 4 of a twin belt caster and a pipe to supply the inert gas in the liquid state to the inside thereof is disposed. The inert gas in the liquid state is dropped into the cover 8 from the supply pipe and the molten metal 5 is made to overflow from the spout 4 while belts 2, 2' of the twin belt caster are driven. The gas in the liquid state evaporates in the cover 8 and forms the inert gaseous atmosphere higher than the atm. pressure in the cover. The spacing between the belts 2, 2' and asbestos cloth is thereby thoroughly sealed and the oxidation of the molten metal is obviated. Since the gaseous atmosphere is gently formed, the surface characteristic of the product and the production efficiency are improved.

摘要： PURPOSE:To prevent penetration of a molten metal into the spacings between small blocks by providing feed rollers in the upperstream position in a pouring section and moving the small blocks to the downstream side at the circumferential speed slightly higher than the moving speed of the dam blocks. CONSTITUTION:A driving device 12 and bearings 14 are disposed on the stand 11 of construction arms 10 on the inlet side of a twin belt caster consisting of a pair of upper and lower endless belts and a pair of right and left dam blocks 4. A driving shaft 15 and a power transmission shaft 16 are coupled by a coupling 13 and dam block feed rollers 5 are provided to the top end of the shaft 16. An outer ring 17 and an inner ring 19 are coupled respectively via springs 21, spring seats 18 and spring guides 20. The rollers 5 are thus rotated at the circumferential speed slightly higher than the moving speed of the blocks 4 so that the blocks are moved to the downstream side in a way as to have no spacings between the small blocks 8. The penetration of a molten metal into the spacing between the small blocks is thus prevented.

SOLUTION: The guide roll is used for continuous casting for a steel, and its inside is water-cooled. The guide roll includes: one cooling hole 2 provided at the central part of a cross-sectional face so as to perform water passing along a shaft direction; and a plurality of cooling holes 3 uniformly provided so as to perform water passing along the shaft direction on almost the same circumference in the surface layer part of the cross-sectional surface. The plurality of the cooling holes 3 provided at the surface layer part are provided in a range to a depth of 50 mm from the surface of the roll. Into the cooling holes 3, cooling water is introduced from the edge part of the roll shaft on either side through the cooling hole 2 provided at the central part in the cross-sectional surface to the vicinity of the edge part of the roll shaft in the other cooling side. The ratio( Hw2/Hw1) of the heat transfer coefficient Hw2 of the plurality of cooling holes 3 in the surface layer part to the heat transfer coefficient Hw1 by the cooling hole in the central part, is controlled to 1.0 to 3.0. The improvement of cooling capacity and the elongation of the service life of the roll upon high speed casting can be achieved.

摘要： PROBLEM TO BE SOLVED: To provide a continuously hammering device for continuous casting of a cast piece having high durability for a long period of time having high durability capable of continuously hammering the cast piece in a transverse direction with prescribed impact energy at prescribed impact vibration frequencies and enabling continuous use for a long period of time even if the cast piece is subjected to large impact at high frequencies while being exposed to the radiation heat from the cast piece of a high temperature, scale, water, etc. SOLUTION: The continuous hammering device comprises: a hammering member 22 for hammering the cast piece 1; a compression springs 30 for biasing the hammering member toward the cast piece; a cam mechanism 32 which moves the hammering member in the direction in which the hammering member separates from the cast piece, thereby compressing the compression springs, and then allows the hammering member to move freely; and a main body 14 for supporting the hammering member, the compression springs, and the cam mechanism. In hammering operation, the cam mechanism 32 is separated from the hammering member 22 and allows the hammering member to accelerate freely. Thereby, the compression energy of the compression springs 30 is converted into kinetic energy of the hammering member 22, and the hammering member 22 collides with the cast piece 1, and thereby the predetermined hammering energy is applied to the cast piece.

摘要： PROBLEM TO BE SOLVED: To provide a continuous casting method by which the formation of oxide in molten metal and the absorption of oxygen and hydrogen by the molten metal are suppressed and a slab of high quality is produced.
SOLUTION: At the time when magnesium alloy molten metal is subjected to continuous casting, the surface of the molten metal 2 in a mold 4 is fed with a liquified inert gas. A protective cover 6 is arranged at an opening part in the upper part of the mold, or further, it is preferable that the feed of the liquified inert gas is performed at a flow rate of 5 to 15 N L/min since the contact between the molten metal and the air can be shielded more effectively.
