摘要： PURPOSE:To obtain a good cast ingot of uniform quality by controlling the velocity of the molten metal to be supplied to a cooled mold, and acting electromagnetic repulsive force upon the molten metal thereby forming a well part of a stable shape on the cooled mold. CONSTITUTION:Molten metal 10 is supplied from a furnace 1 via a trough 6 into a well part 14 from a nozzle 8 while the rate of supply is being controlled by a stopper 7. This nozzle 8 is properly immersed in the part 14, so as to flow the molten metal at the rate as gently as possible into the part 14. In the part 14, the shape is maintained simply by the pinching force generated by an electromagnetic coil 13, and said shape is controlled by controlling induction force distributions by the shapes of the coil or suitably selected shielding materials. On the other hand, the molten metal supplied into a cooled mold 9 forms a thin solidification shell by the heat deprived of from the mold walls. Next, a cast ingot 17 is drawn from the bottom part of the mold 9 by a cylinder 20, and cooling water 18 is sprayed to the ingot 17 to apply quick cooling effect down to its inside, whereby the ingot of superior internal quality is obtained.

摘要： PURPOSE:To prevent the inflow of cooling water in the cylindrical part of a cylindrical metallic member and to prevent bumping by disposing said member on the outside circumference in the upper part of a bottom metal, forming the top edge of said cylindrical body to an annular shape and fusing the same to a casting material abutted on the bottom metal. CONSTITUTION:In a vertical type continuous casting device, a cylidrical metallic foil 5 is put on the bottom metal 2 to be inserted into a mold 1 so as to enclose the outside circumference in the upper part of said metal, and the top end part of the foil 5 is folded to the top edge surface side of the metal 2. A material of a melting point slightly lower than that of molten metal M is used for the foil 5. When molten metal is charged through a nozzle 4 in this state, the foil 5 in the circumferential edge part of the metal 2 solidifies together with the metal M after the foil is once fused to the metal M. Thereafter the metal 2 is moved downward at a prescribed speed, and as the ingot is pulled, the cylindrical part of the foil 5 is taken up upward by the shrinkage on solidifition of the ingot to form a wall for preventing the inflow of the cooling water ejecting through the hole 1a of the mold 1 in the space S between the ingot and the top surface of the metal 2, whereby bumping is prevented.

摘要： PURPOSE:To make possible the controlling of outputs without disturbing later processes by changing the timings of programs according to conditions during progression of program controlling. CONSTITUTION:A standby command is fixed like the solid line in the figure by assuming that the current cooling water flow (y) is not changed. X is defined as drawing length of a cast ingot. If at this time the coordinates after (Xn+1, Yn+1) are fixed, the danger of process stray run occurs at the moment when the standby is released; therefore, the inclination of the graph after the command release beta must be held fixed or the coordinates of Xn+1, Xn+2-must beforehand be moved by the extent having stood by. Since the standby extent is DELTAX, the new coordinates are changed to (Xn+DELTAX, Yn), (Xn+1+DELTAX, Yn+1)-, hence, the cooling water flow (y) is again controlled along the prelimited program, thus the abrupt output fluctuations are averted.

摘要： PURPOSE:To improve magnetic characteristics of extrusion product of sendust alloy, by the heat treatment including high-temp. purification annealing, super-lattice formation of hot extruded sendust alloy. CONSTITUTION:Cast sendust alloy composed of 5-12% Si, 3-8% Al, the balance being Fe, is extruded at an extrusion temp. 1,000-1,290 deg.C, at an extruding ratio . The extruded material is reheated and kept at a temp. not lower than 1,000 deg.C for 1 hour or longer in order to conduct high-temp. purification annealing, then it is cooled slowly at a cooling rate not higher than 100 deg.C/hr so as to promote the formation of super-lattice. Or it is kept in a temp. region 750-600 deg.C for 1 hour or longer after cooled slowly or in the course of cooling so as to conduct transformation annealing for low-temp. super-lattice formation. Or it is cooled slowly after the low-temp. super-lattice formation annealing while applying magnetic field in a direction parallel to the extrusion direction of the material to be extruded. Hereby the magnetic characteristics of sendust alloy is remarkably improved by use of the fact that the anisotropy of the magnetic characteristics is brought about because of the anisotropy caused is sendust alloy by hot extrusion.
