摘要： A fluid control system for selectively self-adjusting mill reduction force or inter-working roll distance or roll gap comprising a variable discharging plunger pump having one port connected to a hydraulic cylinder adapted to apply pressure on working rolls in a mill and the other port connected to a fluid supply source. A servo valve is provided for deflecting deflection means in one or the other direction to control the discharge direction and discharge amount of said pump. In order to detect an existing value of mill reduction force, a fluid pressure detector is provided for electrically detecting fluid pressure in a fluid passage adapted to be connected to said hydraulic cylinder. A detector is provided for producing an electrical signal in response to the position of the ram of the cylinder. The servo valve operates in response to a result of a comparison between signals from the above-mentioned detectors and a reference value and thereby fluid is controlled so that the fluid may be in a predetermined direction and a predetermined amount so as to self-adjust mill reduction force or inter-working roll distance.

摘要： A degassing apparatus (12) for a metal mold (11) comprises a valve body and a bypass. The valve body (24) is slidably provided between an end of a vent groove communicating with a metal mold cavity (14) and a valve opening/closing portion before an exhaust hole. When a molten metal flowing from the cavity acts on a surface of the valve body, the valve body moves toward the exhaust hole and blocks a path toward the exhaust hole. The bypass (26) bypasses a valve head (24b) of the valve body from the vent groove and guides gas to the exhaust hole. The valve head of the valve body has a substantially head-cutting conical outer shape projecting in the direction of the vent groove (15). The vent groove has a gas vent path (25) extending from a top portion to the vicinity of the base of the valve head along an outer surface of the valve head. An end portion of the gas vent path corresponding to the base of the valve head communicates with a start portion of the bypass which bypasses the valve head.

摘要： PURPOSE:To increase a pressurizing force acting on a molten metal in a cavity and to improve a squeeze casting effect by filling the cavity with the molten metal by a casting operation and also reducing the hydraulic pressure in a chamber at a movable disk side of cylinders in the state of continuing die clamping movement. CONSTITUTION:At first, in the state of relatively retreating a liner stem 13 to a movable die 12 by operating the hydraulic pressure to the chamber 9a at the movable disk 7 side of the cylinders 9 between the movable disk 7 and the movable die 12, the movable disk 7 is advanced and the movable die 12 and the liner stem 13 are advanced at the same time to execute the die clamping movement. In this state, the movable disk 7 is perfectly pressed to a fixed die 3 to execute the normal die clamping, and the die clamping force is transferred to the fixed die 3 from the movable disk 7 through the movable die 12. Successively, at the time of decreasing the hydraulic pressure in the chamber 9a at the movable disk 7 side of the cylinder 9 in the state of continuing the die clamping movement while filling up the cavity 14 with molten metal by the injecting operation, the die clamping force from the movable disk 7 is transferred to the liner stem 13, and the liner stem 13 is advanced and the pressurizing force is increased.

摘要： PURPOSE:To manufacture the desired casting product without mixing oxide by inserting and holding wire net, etc., in inner wall part of inlet hole of a runner and supplying molten metal in a die in the case of casting by using the die arranged with the specific shape of the runner in insert hole of a casting sleeve. CONSTITUTION:A dish type attaching brim of the metal net 15 is pushed to the inner wall part 13a of the inlet hole of runner from lower part and held with friction force with this inner wall part 13a. After clamping both dies 2, 4 of upper and lower parts, the molten metal 11 is poured into the casing sleeve 9, and the sleeve 9 is inserted into inner hole in a fixed sleeve 18 and joined. Successively, a plunger tip 10 is advanced under vacuum sucking condition with a gas exhausting device communicating with upper part of cavity 8 to cast the molten metal into the cavity 8. Then, the metal net 15 does not pass the oxide in the molten metal and the oxide can be removed. By this method, the molten metal passed through the metal net is clean and the desired strength of the tensile strength is obtd.

摘要： PURPOSE:To improve quality of cast product and productivity by melting billet corresponding to the casting quantity for one time in a vessel to form molten metal and next, pouring this molten metal into a mold to execute casting. CONSTITUTION:A cavity 7 is formed with dies 5, 6 and also a rotating table 16 is arranged at lower part of a fixed disk 3, and a sleeve table 14 is arranged at the position apart from 180 deg.. A shift cylinder 25 approaches/separates an injection cylinder 22 to/from a fixed sleeve 10 through ascent/descent of a piston rod 26. The billet 28 corresponding to the casting quantity for one time is supplied in the sleeve 22, which is set at outer part position, is melted under vacuum with an electron gun 29. Next, the rotating table 16 is turned at 180 deg. and the injection cylinder 19 is ascended, and the molten metal is injected into the cavity 7 through a plunger 23 and a tir 24. By this method, as development of oxide and impurity in the molten metal is prevented, the quality of the product and the productivity are improved.

摘要： PURPOSE:To considerably decrease dissipation of dusts into the atmosphere and improve dust collection efficiency by directing the notch or opening of each dust precipitating electrode to the direction opposing to the gas flow, and capturing the dusts which are rescattered by hammering impact into their inside surfaces. CONSTITUTION:A dust precipitating electrode 1 is so constituted that a notch 2 is directed over the entire length of the pipe toward the direction where dusts pass, like a half split pipe. The particles scattered by hammering flow to the dust precipitating electrodes 1 of the lower positions and stick thereon. These are divided largely to the particles b1 sticking on the outside surface of the half-split pipes and the particles b2 sticking on their inside surfaces. The greater part thereof are the particles b2. Even if the dust particles stuck on the inside surfaces receive the force in the gas flow direction by the subsequent hammering, they are blocked by the pipe walls of the dust precipitating electrodes, and are further prevented from going toward the dust precipitating electrodes of the lower positions, thus they fall by gravity along the pipe walls. In this way, the greater part of the dust pariticles are prevented from going toward the dust precipitating electrodes of the next positions.
