Title: Method for continuously casting molten steel
Inventor: KONDO KATSUMI
IPC: B22D11/108
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To improve the quality of a steel product and the yield by making powders having the characteristics desirable for preventing longitudinal crack on a cast slab, for preventing internal defect in the cast slab and for preventing breakout, and selectively using them for casting. SOLUTION: In the granular powder for preventing the longitudinal crack on the cast slab, having 0.8-1.5 basicity and 1100-1250 deg.C solidified temp., the granular powder for preventing the internal defect in the cast slab, having 3.5-4.5 poise (at 1300 deg.C) viscosity and the hollow powder for preventing the breakout, forming these powder to the hollow shape, the powder having one or more characteristics is separately made and selectively used at the time of casting. Since the longitudinal crack is affected by heat conduction quantity, the heat conductive quantity so as not to cause the longitudinal crack, is controlled with the powder flowing down into the gap between the inner wall of the mold and the molten steel. Since the interval defect in the cast slab is caused by the entrapment of the powder, the powder having a viscosity characteristic of difficult-to-entrap, is used.  Since the break-out is caused by insufficiently flowing of the powder into the gap between the inner wall of the mold and the molten steel, the powder having the characteristic of easy-to-flow in, is used.

Filed: 1994-01-18
Abstract: PURPOSE:To reverse a garbage container held in lashed state by interlocking the motion thereof with the expanding and contracting motion of a lift cylinder, without any need of fitting an actuator for the operation of a lashing means to secure the container to a holding seat. CONSTITUTION:A clamp member 52 turns upward as well, together with a joint member 53, due to the expansion of a lift cylinder 6, thereby clamping the upper end section A1 of a garbage container A. When the lift cylinder 6 is further expanded, a holding seat 4 turns upward and the container A is lifted upward with the member 52 and a holding piece 51. As a result of this turning motion, a stopper 55 is inserted in and coupled to the insertion hole of the holding seat 4, due to the energizing force of a spring. Also, the clamp member 52 firmly holds the upper end section A1 of the container A in cooperation with the holding piece 51, as a result of the insertion and coupling of the stopper 55 to the insertion hole, thereby prohibiting a turning motion in a clamp releasing direction. When the lift cylinder 6 is further expanded from that state, the seat 4 is reversed and garbage therein is delivered to a garbage discharge box 1 via a discharge opening 11.
