Title: Improving method of solidified structure of casting surface
Inventor: SAEKI TAKESHI
IPC: B22D7/00
Filed: 1979-07-09
Abstract: PURPOSE: To form dense solidified structure in the surface layer by applying predetermined high-frequency oscillations until molten metal is solidified to a predetermined thickness.  
     CONSTITUTION: High-frequency oscillations of 5W50kHz are applied to solidifying metal until the finely grained solidified shell in its surface layer becomes 5W30mm thick. For example, molten steel 1 of 0.15% C, 0.20% Si, 0.80% Mn, 0.020% P, 0.020% S, 0.020% Al and Fe for the remainder is put in a mold 2 of 100mm× 1,200mm×800mm and is continuously cast at a 0.9m/min drawing speed. High-frequency oscillations of 18kHz frequency are applied to the mole 2 at 50kW output by a high-frequency oscillator 4 via a horn 5 and an oscillation transmitting plate 6. (5kW/face×2 faces=10kW on the mold wall faces adjacent to the short side of 100mm of the ingot, 20kW/face×2 faces=4CkW on the long side of 120mm side of the ingot, total 50kW). Thereby, the fine free crystal portions are obtained from the surface down to a depth of 15mm and the solidified structure of the casting surfaces is improved.

Abstract: PURPOSE:To obtain a high density image by the short-time irradiation with light by providing a light absorbing heating layer wherein a light absorbing heating material is dispersed in a binder to the single surface of a support and providing a colorant layer containing a sublimable dye to the opposite surface thereof. CONSTITUTION:A light absorbing heating layer 2 wherein a light absorbing heating material is dispersed in a binder is formed to the single surface of a support 1 and a colorant layer 3 containing a sublimable dye is formed to the opposite surface thereof. Both surfaces of the light absorbing heating layer 2 are in contact with the support 1 and the atmosphere but, since the heat conductivity from the light absorbing heating layer 2 is larger on the side of the support 1 as compared with the side of the atmosphere, the greater part of the heat energy generated in the light absorbing heating layer 2 is conducted and transferred through the support 1 to reach the colorant layer 3 and the sublimable dye contained in the colorant layer 3 is instantaneously melted, sublimed and scattered to be adsorbed by or to penetrate in image receiving paper 6 to be transferred thereto and image recording is performed. At this time, the scattered substance of the light absorbing heating material and binder contained in the light absorbing heating layer 2 is not adhered to the image receiving paper 7 because of the presence of the support 1 and a recording image is not contaminated.
