Patent JP-H03183721-A (JP)
Title: Calcium treatment of molten steel
Inventor: KAWACHI YUJI
IPC: B22D1/00
Filed: 1989-12-12
Abstract: PURPOSE:To suppress the formation of CaS so as to reform the Al2O3 in a molten steel to a compd. with CaO of a low m.p. and to prevent the closing of the small-sized nozzle of a continuous casting device by adding Ca at a specific ratio according to the content of C in the molten steel of the raw material to the molten steel at the time of producing blooms and billets of small sectional areas as blank materials for steel bars and wires by continuous casting. CONSTITUTION:The molten steel contg. <0.100wt.% Al and <0.150wt.% S is poured from an immersion nozzle having a small inside diameter into the continuous casting mold of a small sectional area at the time of producing the blooms and billets of the small sectional areas as the blank materials for the steel bars and wires by continuous casting. The nozzle is clogged by sticking of the Al2O3 as the nonmetallic inclusion in the molten steel sticks to the immersion nozzle and the continuous casting operation stops in this case. The Ca is added to the molten steel under the conditions expressed by equation according to the content of the C in the molten steel in order to prevent such stop. The Al2O3 of the high m.p. is thereby converted to 12CaO.7Al2O3 of a low m.p. while the formation of the CaS is suppressed, by which the sticking of the Al2O3 to the inside surface of the small-diameter immersion nozzle is prevented and the instability of the continuous casting operation by the clogging of the nozzle is eliminated.

Abstract: PURPOSE:To detect the lubricant quantity of an oil feeder from the outside without stopping an elevator by providing a detector detecting the liquid level with the electric output corresponding to the lubricant liquid level of the oil feeder feeding a lubricant to guide rails and a display device of the lubricant quantity corresponding to the electric output. CONSTITUTION:When the liquid level of a lubricant 7 in the oil tank 81 of an oil feeder 8 is at the upper limit position, it is the electric balance position, no output voltage is generated, and an indicator lamp 112 is not lighted. As the lubricant 7 is consumed and the liquid level in the oil tank 81 is lowered, the electrostatic capacity between electrodes 91, 92 is changed to generate the output voltage, and the indicator lamp 112 is lighted. When the output voltage is gradually increased and the brightness of the indicator lamp 112 is increased to the preset limit and exceeds the limit, such an abnormality occurs as the burnout of the indicator lamp 12, a current flows in a detecting relay 113 to operate it, contacts are excited, and an indicator lamp 115 is lighted to report the abnormality. The quantity of the lubricant 7 is judged by the brightness of the indicator lamp 112, and the abnormality of the lubricant quantity can be confirmed by the lighting of the other indicator lamp 115.

Title: Method of deaerating thermoplastic synthetic resin melt within wide viscous range and extruder
Inventor: HANSU FUOTSUBE
IPC: B29C48/76
Filed: 1988-12-23
Abstract: PURPOSE: To ensure the optimum partial filling of screw flights and the max. extrusion quantity of a degassing extruder by controlling the melt filling degree of screw flights by a pressure gradient and feeding a melt in a degassing stage by the almost same transport capacity. CONSTITUTION: When pressures at points PE3, PE4 are measured and the corresponding pressure gradient is generated by a control unit 25, the control unit 25 acts on a control slider 38 newly to start operation so as to make a free cross-sectional area slightly large. Even in this case, by generating the pressure gradient perfectly regardless of the viscosity of a melt, in its turn, the flow index thereof, the uniform filling height and length of screw flights in a section 35 are achieved. In order to obtain the optimum filling degree or length in such a case that the filling degree of the screw flights of a degassing means is too small, the number of rotations of a melt pump 49 is lowered by the control unit 25 through an adjusting device 51 and a drive motor 50.  Screw flights are filled until the pressure gradient calculated by this method becomes the optimum filling degree and length.

The set value correcting means 4 compares the amount (e) of consumable energy for one hour, which is set by the energy consumption setting means 8, with the energy consumption estimating value E and when e>E, the set value correcting means 4 outputs the value of TS to a controller 2. When e<E, TS it risen by 1 deg.C upon heating and Ts is reduced by 1 deg.C upon heating while said operations are repeated until E becomes smaller than (e) and the value of TS when E becomes lower than (e) is outputted into the controller 2.
