Title: Method of identifying molten steel and slag in molten steel channel
Inventor: KURITA SUMIHIKO
IPC: C21C5/46
Filed: 1979-05-23
Abstract: PURPOSE:To make the molten slag and oxide film on the surface identifiable from the molten steel by dipping a light-transmittable, heat-resistant and molten-steel- resistant ceramic rod into the molten steel flow and taking out the radiation energy of the surface by the rod. CONSTITUTION:At the time of tilting a refining furnace or ladle 1 and letting molten steel 3 flow out, a rod 4 of ceramics having molten steel resistance and light transmittance such as sapphire is dipped in the molten steel flow 7 and the radiation energy of the molten steel flow 7 is led into a radiation energy measuring device 5 through the ceramic rod 4. While the molten steel flow 7 is molten steel, a stopper 6 does not actuate and when the molten steel flow 7 changes to molten slag flow, the stopper 6 is actuated by the difference of the radiation energy possessed by the molten steel and molten slag to let the molten steel flow out together with the molten steel, whereby their mixing is automatically prevented.

Title: Blooming method for rough shaped billet
Inventor: HASEGAWA MASAHIKO
IPC: B21B1/02
Filed: 1979-05-28
Abstract: PURPOSE:To obtain the rough shaped billet with good quality and shape, by applying the thickness reduction to the top in the longitudinal direction of the square ingot more strongly than to the bottom, in order to make disproportionate the thickness of the billet. CONSTITUTION:In the first rolling stage for rolling the calibered square ingot into the square rough shaped billet, the surface flaw in the top of the rough shaped billet can be prevented by increasing the total rolling reduction. Besides, the crops on both tips of the billet become large if the total rolling reduction is large, and the yield declines. Hence, a strong thickness reduction is given to the top of the ingot, and a thickness reduction milder than the top is given to the bottom of ingot. That is, the disproportionately thick calibered rough shaped billet, in which the thickness is disproportionate along the longitude of the calibered rough shaped billet, is prepared. For example, the thickness hT at the top and the thickness hB at the bottom are specified to be hT<hB. By taking this billet as the starting material for rolling the rough shaped billet for manufacturing the shape, the material property and the shape of tips are improved.

Abstract: PURPOSE:To execute quenching while reducing the development of oxidized scale by dipping a steel material being held both the end parts with electrodes into water, conducting the electric current from both the electrodes to heat the steel material, holding at a prescribed temp. with pulse oscillation of conductive current and successively cooling with water. CONSTITUTION:In the condition of clamping both ends of a pipe-like steel material 1 by the electrodes 3, 3 the steel material is dipped into a vessel 4 incorporating hydrogen as liquid for cooling 2, and by conducting the current from both the electrodes 3, 3, the steel material is heated to the necessary quenching temp. by the resistant heat of the steel material 1. After raising the temp., the pulse oscillation of the conductive current is executed to keep the temp. of the steel material 1, and after the pulse treatment is continued for a time during which the carbide in the steel material sufficiently comes to solid solution, the conduction of current is stopped. Thereafter, immediately, water 2 is stirred to rapidly cool and quench the steel material 1. As the content of oxygen in the water is extremely low, the oxidized scale developed on the steel material surface is slight, compared with the quenching in the air, and the quenching is uniformly executed in good thermal efficiency.
