Title: Operating method for continuous casting machine
Inventor: KAZAMA HISAO
IPC: B22D11/12
Filed: 1981-04-10
Abstract: PURPOSE:To suppress the generation of cracks, to improve the quality of ingots and to stabilize operation in vertical type continuous casting by bringing dummy bar pinch rolls into contact with the ingot with weak pressurizing forces. CONSTITUTION:In the operation of a vertical type continuous casting machine, the cylinder pressure on the ingot pressing side of oil hydraulic cylinders is changed over to low pressure according to ingot sizes or the like, at the point of the time when the ingot 3 drawn from the inside of a mold 2 arrives at the positions of dummy bar pinch rolls 5, 5'. Thereby, the weak pressurizing forces of the extent of not compressing the ingot 3 bring the rolls 5, 5' into contact with the ingot and hold these. According to this method. the roll 5, 5' can play the role of guide rollers and therefore the ingot 3 is prevented from bending and cambering and also the ingot 3 is prevented from disengaging from the head part of the dummy bar. Hence, it is possible to suppress the bulging of the ingot and to suppress its cracking considerably.

IPC: H01F1/08
Filed: 1985-03-20
Abstract: PURPOSE:To contrive improvement in the squareness of a demagnetization curve by a method wherein the pulverized alloy of specific composition is heat- treated under the specific conditions. CONSTITUTION:The alloy, shown by the general formula R(T, M)z, consisting of the mixture R of one or two or more kinds of rare-earth metals, the transition metal T mainly composed of Fe and Co, and the metalloid element M mainly composed of B, is used. Said alloy is pulverized into the grains of 5-100mum in diameter, a heat treatment is performed in a hydrogen or inert gas atmosphere or in a vacuum at the temperature range of 300-1,100 deg.C; it is cooled, fixed with an organic polymer and the like, and a magnet is formed. The mechanical distortion of the fine powder generated in the pulverizing process can not be removed at the heat treatment temperature of less than 300 deg.C, and when said temperature exceeds 1,100 deg.C, the individual powder is fused and adhered one another. Therefore, it is desirable that the heat treatment is performed at 300-1,100 deg.C. By performing the above-mentioned treatment, the mechanical distortion is removed, and the squareness of demagnetization curve can be improved remarkably.

Title: Method for controlling surface position of roll in continuous casting
Inventor: OOKUBO NAOTAKE
IPC: B22D11/16
Filed: 1980-04-24
Abstract: PURPOSE: To prevent center cracking or the like and improve quality by measuring the forces in the ingot thickness direction exerted upon ingot holding rolls, or the change state of the surface position thereby controlling cooling intensity.  
     CONSTITUTION: The diameters of rolls 2, 3 fluctuate and the output signals of load cells 4, 5 fluctuate in accordance with the thermal expansion or shrinkage during pouring period. In the case of making constant-pressure controlling, the output of the load cells 5 is not the one that follows up the change in the roll diameter and therefore it is necessary to measure the surface position of the roll with noncontact displacement meters (for example, vortex type displacement meters) 9, 10. In this way, the change state of the diameters of the rolls 2, 3 are measured and based on the measured values, the control valves of water supply pipes 8, 8', 11, 11' are controlled to regulate the flow rates of the cooling water to be flowed into the rolls 2, 3, whereby the rates of thermal expansion or contraction of the rolls per se are controlled and the roll diameters is adjusted to desired values.
