摘要： PURPOSE:To prevent the development of crack in solidified shell by beforehand forming heat insulating film of casting powder on the surface of a belt with adhesive agent and executing continuous casting through the heat insulating film surface of the belt. CONSTITUTION:On the upper side of the belt 11 before coming to mold part 10, an adhesive agent coating device 1 and a power spread device 5 are arranged. At first, a coating roller 3 is rotated by following with the belt 11, and the adhesive agent C in a vessel 2 is coated on the surface of each belt 11. Successively, the casting powder P in a powder supplying device 6 is spread to the whole width of the belt 11 with a fixed quantity supplying machine 8 through a chute 9. When this heat insulating film surface of the belt 11 reaches in the mold 10, the molten metal R is supplied to the mold part 10, to execute the casting. As the film heat insulating layer having uniform thickness is formed between the belt 11 and the molten metal R, cooling is made to slow and after that, the film is detached with the pulley 13. By this method, the development of crack in the solidified shell is prevented.

摘要： PURPOSE:To freely change width of a cast slab by matching two sets of devices providing driving mechanism for running a link to form a side dam and independently shifting two sets of devices, respectively. CONSTITUTION:By protruding B unit toward center direction of the belt 30 by distance (a) at the time of casting A unit by the slab width W', as the side dam block 1b of the B unit comes in gap between belts 30 after half circular moving, the narrower slab 21 can be produced by (a). In the width changing, when boundary joining part of both blocks 1a, 1b comes to the horizontal direction, by protruding the B unit, both side blocks 1a, 1b forms the step difference (a) at the boundary joining part as mutually sliding. By repeatedly executing this motion with A and E units, the widely width change of the slab 21 can be executed.

摘要： PURPOSE:To prevent development of solidified phenomenon of molten metal between belts and outside wall of a nozzle and nozzle clogging phenomenon by arranging a refractory in gap between mold pouring metal surface at space between one pair of belts and a tundish. CONSTITUTION:The molten metal in a ladle 20 is introduced to a tundish nozzles 12, 12' through a tundish 13 and flowed out on surface of inclined plates 11, 11' from a notching part 12a, 12a' at lower end of the nozzles 12, 12'. This molten metal flowed out is flowed out is flowed against the refractory plate 10 on the inclined plates 11, 11' while spreading the molten metal to layer-state toward width direction of a slab on the inclined plates 11, 11'. After being brought into contact with the refractory plate 10, the molten metal is dropped along both surface thereof and introduced to the pouring surface. The flow of the molten metal along both surface of the refractory plate 10 becomes laminar flow, and uniform pouring of the molten metal is executed to the width direction of the pouring surface 8. Further, as the refractory surface 10 is submerged into the pouring surface 8 at some depth, the casting preventing spattering of the molten metal is executed.

摘要： PURPOSE:To reduce an equipment cost and to uniformize a water supply by forming a water jacket with an outer cylinder and attachable and detachable inner cylinder and arranging the manihold for water supply to the outer cylinder and a spray nozzle to the inner cylinder. CONSTITUTION:A water jacket 20 is composed of an outer cylinder 2, upper part cover body 9 and flanged inner cylinder 8 and the outer cylinder 2 is taken to be of the structure usable as well for the dimension of a billet 5. In this case the manifold (m) for water supply is fitted to the outer cylinder 2 and plural spray nozzles 3 are arranged at the inside of the inner cylinder 8 as well. A cooling water (w) is projected to a mold main body 1 from the nozzle 3 via a water supply hole 6, vibration table 7 and manihold (w). At the time of changing the dimension of the billet 5 the inner cylinder 8 and mold 1 are changed with the necessary dimentional one. Owing to the inner cylinder 8 and mold 1 being exchangeable the equipment cost is reduced and the water supply of the cooling water (w) is uniformized by the formation of a water jacket 20.

摘要： PURPOSE:To treat cooling water for a continuous casting equipment to remove completely scales generated by carbonic ion and bicarbonic ion by adding an acid in the cooling water and evaporating carbonic acid gas generated thereby directly from the cooling system. CONSTITUTION:An acid 10 such as sulfuric acid, etc., is added to a supplying water flown in 5 by an acid pouring pump P4 through an acid pouring line 11 and a mixing vessel 12, and adjusted 13 to be 7.0 pH of the water in a cooling vessel 3. By this operation, the supplying water with 6.9 pH and 20.0 ppm of M alkalinity becomes to 6.3 pH and 3.6 ppm M alkalinity at a sampling position SM1 and a corresponding part for 16.4 ppm of M alkalinity changes to the carbonic acid gas. Next, the supplying water is flowed into the vessel 2 and mixed together with the returned circulating water from the mold, and then it is cooled and removed as the carbonic acid at a cooling tower 4 and flowed P3 into the mold 1. As result of this treatment, the scales attached in the mold are decreased to about half of them in case of adding the conventional dispersion agent into the cooling water.

摘要： PURPOSE:To improve the cooling effect and life of a mold plate for continuous casting formed by providing cut grooves to a steel plate joined to a copper alloy until the copper alloy on the base is exposed by welding individually seats for bolts to the upper parts of the cut grooves. CONSTITUTION:The mold is formed by joining a mold plate 1 and a reinforcing plate 2 and cooling water paths 3 are cut to the plate 2. The open parts of the cooling water depth 3 are made into closed pipelines and a supporting plate 4 is fastened to the mold plate M in order to support the plate M. The bolt seats 7 made of the same materials as the material of the plate 2 are welded to the paths 3 and ribs 6 provided between the paths 3. The plate 4 and the plate 2 are fastened by means of bolts 5. The sectional area of the cooling water paths 3 and the effective area of the cooling surface are thus made approximately uniform in the longitudinal direction of the mold, by which the mold having the excellent cooling effect and the long life is thus obtd.
