摘要： PURPOSE: To provide a mold of a continuous caster for thin slab, in which guide rolls below the mold are simple and so complicate operation as to open the guide rolls even at the time of passing through the tip part of the cast slab is unnecessary and the thin slab having good quality can be cast. CONSTITUTION: The mold is composed of one pair of long side mold walls 1, 1 and one pair of short side mold walls 2, 2, and the one pair of short side mold walls 2, 2 are mutually parallel and the one pair of long side mold walls 1, 1 give the taper gradually reduced toward the lower end of the mold M from the upper end of the mold M in the mutual interval. The thin cast slab can be cast at the lower end of the mold M while having the width inserting an immersion nozzle at the upper end of the mold M. Further, the rolling reduction in the following process is unnecessary and the possibility in which the thin cast slab can directly be cast is enlarged.

摘要： PURPOSE:To make the last solidified positions in flange parts and a web part the same position and to improve quality of a product by forcedly cooling the flange parts while a beam blank exists yet in the mold. CONSTITUTION:The flange forming parts 2 are forcedly cooled and the web forming part 3 is slowly cooled by flow rate control for cooling water in the mold 1. Further, the flange parts 5 in the beam blank goes out to the outer part faster than the web part 6 and directly and forcedly cooled with the water from the spray device 4 for cooling water. Therefore, each of the last solidified positions in the web part and the flange parts is made to the same position, and the whole beam blank can be held to the uniform temp. By this method, even the beam blank having the shape similar to that of the H beam steel of the finished product, can be produced with continuous casting while surely holding good quality.

摘要： PURPOSE:To prolong the life of a refractory product by transforming inert gas into plasma in a refractory container and circulating the inert gas in the refractory container as the inert gas is heated by the heat of the plasma gas. CONSTITUTION:The refractory container 1 is charged with the inert gas. Thereafter, the inert gas is formed by a plasma torch 5 inserted and fixed in the container 1 into plasma. This plasma gas is blown out of the tip of a cylindrical nozzle 6 enclosing the front range of the plasma torch 5 and the inert gas is sucked from the side range of the plasma torch 5 to the front range thereof. As the inert gas is heated by the heat of the plasma gas, the inert gas is circulated in the refractory container 1 and the inert gas is supplied and a portion of the circulating gas is exhausted from an exhaust port 4. In this way, preheating operation can be improved in efficiency, power can be saved and cost of equipment can be reduced.

摘要： PURPOSE:To moderate discharging flow and to prevent entraping of powder by communicating molten metal through plural branched passages and the branched passages at the downstream side through a communicating passage, joining and colliding the molten metal, reducing velocity energy and discharging. CONSTITUTION:The molten metal is introduced in the upper end of an immersion nozzle 1 from a tundish and branched into a first branched passage 1 and a second branched passage 12 and flowed down through each branched passages 11, 12. As the molten metal through the first branched passage 11 is joined so as to collide to the molten metal flowing down a second branched passage 12 through the communicating passage 16 formed at the lower end part of an inner cylinder 6 from the almost horizontal direction because the lower end of the branched passage 11 is closed. By this method, the molten metals flowed clown through the first branched passage 11 and the second branched passage 12 are acted so as to reduce mutual velocity energy. Therefore, a discharging flows from discharging holes 14, 15 are reduced and become gentle to prevent the entraping of the powder caused by stirring.

摘要： PURPOSE:To surely manufacture a beam blank having long web part by arranging a recessed groove as molten metal supplying hole at almost center of the web forming part in a mold and rolling this cast billet to the prescribed thickness while unsolidified part exists in shell inner part. CONSTITUTION:As the molten metal supplying holes C1, C2 are arranged at almost center of flange forming parts 2 and the web forming part 3, running of the molten metal is in good condition. As bulging part 3' developed in the recessed groove 4 at almost center of the web part 3' in the beam blank M, is rolled to the prescribed web thickness with rolling reduction roll 6 arranged just below the mold 1 under condition, which the unsolidified part exists, a continuous casting apparatus for producing the beam blank whose shape is similar to that of H-bear steel and I-beam steel while keeping good running of molten metal, i.e., good shape, can be obtd.

摘要： PURPOSE:To effectively cope with change of continuous casting of different kinds of steels or casting velocity by making the mold copper plate at inserting side of a rectangular mold adjustable toward opening direction at the lower end thereof together with a backup frame. CONSTITUTION:A U-shaped notching groove 15 is formed at back face of a long side frame 3 and back faces of upper frame 3V and lower frame 3L are connected with a hydraulic cylinder 16, and at the time of working the hydraulic cylinder 16, the lower frame 3L is swung with the notching groove 15 as center so as to change the taper. Thermocouple 17 is embedded so that the junction point is positioned in a long side copper plate 1, and the signal is processed with a controller 19 to change stroke of the hydraulic cylinder 16. As tapered rate of the long side wall in the mold in accordance with shrinkage of a cast slab can be changed according to the casting condition, this equipment can effectively cope with change of conditions and the high velocity casting is possible.

摘要： PURPOSE:To divert a single mold to twin molds and to considerably decrease spare molds by fitting a core frame provided with an intermediate copper plate into the space between a long side copper plate pair and short side copper plate pair which are positioned and fastened by the frame of the single mold and vertically clamping the same. CONSTITUTION:The single mold is constituted of the long side stationary frame 21, long side free frame 20 as well as the long side copper plate pair 18 and short side copper plate pair 2 positioned and fastened 19 to both short side frames 1. The intermediate frame 4 is fitted to the space between the long side copper plates 18 and the intermediate copper plates 3 are clamped by means of bolts 15, 28 and detaining bolts 5, 6 and by exerting an oil pressure to hydraulic chambers 11, 13. The single mold can be diverted to the twin mold of an optional width. The spare molds are thus considerably decreased and the cost of the mold is reduced.

摘要： PURPOSE: To provide a compressive roll device for a cast slab in a continuous caster for thin slab, in which the bulging, etc., is not developed during casting without developing fault and wave on the surface of the cast slab. CONSTITUTION: Each of the compressive rolls in the compressive roll device for cast slab, arranged just below a mold for thin slab is divided into three rolls at least a left roll 1, center roll 2 and a right roll 3. Three rolls are all the same outer diameter straight roll, and the center roll 2 is eccentrically supported to the left and the right rolls 1, 3 and the roll interval of the center roll 2 is made larger than the roll interval of the left and the right rolls 1, 3, and the eccentric quantities are large in the compressive roll near the mold and made smaller toward the compressive rolls far from the mold. By this constitution, the center bulging part of the cast slab is pressed in order. Then, since the circulating speed of each of the rolls 1, 2, 3 is not different, the surface of the cast slab is not damaged.
