Title: Multiple point straightening bending type continuous casting machine
Inventor: UMEZAWA KAZUMASA
IPC: B22D11/128
Filed: 1987-05-21
Abstract: PURPOSE:To prevent development of diagonal crack in a cast slab by making recessed crown roll of cast slab straightening rolls at outside of bending in straightening zone and forming the straightening rolls at inside of bending as projected crown. CONSTITUTION:In multiple point straightening Bending type continuous casting machine, the roll 8i at outside and the roll 7i at inside of bending at No. (i) in the straightening zone 3 are formed as the recessed crown roll and the projected crown roll having 8i and 7i crown rates operated based on the prescribed equation, respectively. By this method, in the bending straightening process of the cast slab 11 (straightening zone 3), as restriction by the straightening rolls 7i, 8i are remarkably relaxed, it is prevented that development of strain is concentrated to the short side corner part at inside of the bending. Therefore, as the development of the strain is ideally dispersed, the development of the diagonal crack in the cast slab is surely prevented.

Title: Continuous casting method
Inventor: UCHIMURA MITSUO
IPC: B22D11/20
Filed: 1990-05-15
Abstract: PURPOSE:To stably achieve segregation improving effect under light rolling reduction by measuring the rolling reduction quantities at two or more positions of a cast slab with free rolling reduction roll at the end stage of solidification, deriving the rolling reduction quantity calculating equations for each roll and controlling roll gap and the rolling reduction force so as to make the rolling reduction quantity suitable. CONSTITUTION:By using the measured rolling reduction, (a) and (m) are decided with the equation 1 and the rolling reduction to each roll is controlled so as to become the suitable quantity based on the equations 4, 5. By using (a) and (m) calculated with the equations 1, 2, 3 after measuring and time ti, which this cast slab needs to shift from the mold meniscus to the (i)th rolling reduction roll, the rolling reduction to each roll can be quantified. The suitable rolling reduction can be obtd. by controlling the rolling reduction force and roll radius, and in the case the rolling reduction is too much, by inserting a spacer at between bearings in roll interval to limit the rolling reduction, the rolling reduction to each roll can be made to suitable, too. By this method, a steel having uniform quality without any internal crack and segregation can be stably obtd.

Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent the abrupt boiling and the nitrogen pick-up at the initial reducing period and to restrain the erosion of refractory in an immersion tube by specifying the range of a bottom-blown Ar flow rate during charging Al for reduction under a specific vacuum degree, thereafter, returning to atmospheric pressure, ascending a vessel and at the same time, regulating the bottom- blow Ar flow rate to the specific range. SOLUTION: An immersion tube 3 is dipped into molten steel 2 having >=5% Cr in a ladle 1 and decarburize-refining is executed by blowing oxygen while supplying Ar gas from a porous plug 4. After stopping the oxygen-blowing, degassing treatment is executed and further, the Al 5 for reduction is charged from the upper part of solid slag 6 and thermite reaction is developed to reduction-recover Cr2 O3 produced during oxygen-blowing. Therein, the bottom- blow Ar flow rate during charging the Al 5 for reduction, is regulated to the range of 0.1-3 Nl/min.t and the vacuum degree is regulated to low degree of <=400 Torr. Thereafter, the pressure is returned to the atmosphere and the vessel 3 providing the immersion tube at the lower part is ascended and at the same time, the bottom-blown Ar flow rate is regulated to the range of 5-10 Nl/min.t.

Abstract: PURPOSE:To always obtain cooling efficiency while refrigerant exists in effective quantity to cool an element by providing a cooling fan for cooling an inner vapor layer, bellows elongated state detecting means in a bellows vessel, and operating the fan when the bellows elongated state is detected by the detecting means. CONSTITUTION:A bellows vessel 10 which can be elongated or contracted with high thermal conductivity and has a cover 11 around an integrated circuit element 1 to be mounted on a printed board 1 is sealed and mounted, and an element 2 is dipped in refrigerant A filled in the vessel 10. A vapor layer cooling fan 12 is mounted outside the vessel 10. Accordingly, when the pressure of the vapor layer is raised and cooling efficiency is lowered, pressure rise is limited by the elongation of the vessel 10. In this case, the fan 12 is driven by detecting means 13, 14 to cool the layer via the vessel 10. Thus, the vessel 10 is returned to its contracted state of low vapor pressure. In this manner, high cooling efficiency is maintained with the refrigerant to immerse and cool the element.
