Definitions
- the present invention relates to a continuous metal structure, particularly a vertical continuous structure.
- the present invention relates to a method of manufacturing a continuous field piece that can reduce the depth of a simulation mark and obtain a piece with less segregation of a mark valley.
- the present invention significantly reduces segregation at the oscillation mark valleys on the surface of a piece, as well as high cycle conditions, even in a low cycle with a small life frequency f, and has a stable structure. It is an object of the present invention to provide a method for extracting a connecting piece that enables the drawing. Disclosure of the invention
- the present invention relates to a positive strip and a negative strip while vibrating in a vertical direction a mold for a vertical continuous structure having two pairs of cylindrical walls forming a structure. At least one pair of ⁇ -shaped walls is moved away from the solidified shell at one time in each time period within the time zone, and the ⁇ -shaped walls are moved away from the solidified shell during other time periods. That repeats during continuous production This is the construction method.
- a positive strip having no negative strip time zone while vibrating in a vertical direction a vertical continuous manufacturing die formed by forming a manufacturing space by two pairs of die walls. At least one pair of ⁇ -shaped walls is moved away from the solidified shell at one time in each of the ⁇ -shaped rising and falling zones, and the other ⁇ -shaped rising and falling time zones.
- a series of operations for bringing the ⁇ -shaped wall away from the solidification shell into close proximity can be repeated during continuous production.
- FIG. 1 is a graph showing a temporal change of a vertical vibration velocity and a horizontal displacement of a rectangular wall according to an embodiment of the present invention.
- FIG. 2 is a graph showing the time-dependent changes in the vertical vibration velocity of the ⁇ type and the horizontal displacement of the ⁇ type wall according to another embodiment of the present invention.
- FIG. 3 is a schematic perspective view showing a ⁇ -shaped horizontal moving device used for carrying out the present invention.
- FIG. 4 is a schematic diagram showing an oscillation mark and a segregation layer.
- FIG. 5 is a graph showing a conventional type I vibration waveform and a type III retraction and forward timing.
- FIG. 6 is a schematic diagram between the ⁇ -shaped wall and the solidified sur. BEST MODE FOR CARRYING OUT THE INVENTION
- the mold powder 10 on the molten steel 11 flows sufficiently between the mold wall 9 and the solidification shell 12 to reduce the frictional force between the rust mold wall 9 and the solidification shell.
- Y indicates the direction of pulling out one piece.
- the frictional force acting on the initial type solidified shell in the type II mask portion is Considering the frictional force between the mold and the solidified shell, the shear force of the mold powder between the mold and the solidified shell can be calculated by the following equation.
- V Relative velocity between the ⁇ type wall and the solidification shell
- the friction force F acting on the solidified shell decreases when the distance X between the ⁇ type and the solidified shell is increased. That is, according to the present invention, the tensile force and the compressive force acting on the shell of the meniscus portion in the early stage of solidification can be greatly reduced, and as a result, the continuity of the solidified shell is maintained, so that the oscillation mark depth is shallow. In other words, the probability that a prayer is formed in the Mark Valley is smaller than in the conventional technology.
- the effects described above are not largely affected by the waveform of vertical vibration waveform ⁇ ⁇ , which causes the wall of the mold to move forward and backward (close and open) in the horizontal direction (hereinafter referred to as horizontal vibration).
- the longitudinal vibration shown in Fig. 1 is a sinusoidal wave, and the horizontal vibration is a trapezoidal wave.
- the amplitude of the horizontal vibration is desirably within 1 mm in order to prevent the risk of the molten metal to enter the gap between the rectangular corners and to cause a restraint break.
- a short side 2 of a rectangular shape is fixed to a long side 1 of a rectangular shape through a panel 3 for a short side clamp.
- the method of doing it is taken.
- the opening and closing of the short-side clamp hydraulic cylinder 4 is provided in the hydraulic circuit. Therefore, in the present invention, the opening and closing of the short-side clamp hydraulic cylinder 4 is also provided in the hydraulic circuit.
- the ⁇ -shaped movement is performed.
- 7 indicates a hydraulic motor
- 8 indicates a hydraulic tank. If a gap is left between the long side of the mold and the short side of the mold during fabrication, molten steel will enter the gap and cause trouble. easy. Therefore, the retraction amount of type ⁇ shall be within lmm.
- the conventional longitudinal vibration (sign wave) and the case of the vibration wave shown in FIGS. 5 (a) and (b) shown in Japanese Patent Application Laid-Open No. 2-290656 are disclosed. A survey was also conducted. Fig.
- Fig. 5 (a) shows the case where the vibration of type III moves the type wall backward during the negative strip period
- Fig. 5 (b) shows the type when the type III descends. This is the case where is retracted.
- Vibration conditions Oscillation Remarks Horizontal vibration conditions Thickness Occurrence rate
- Table 1 shows the results of the above slab comparison between Examples 1 and 2 and the conventional method. Table 1 shows that, according to the present invention, as compared with the conventional method, the incidence of occurrence of the prayer in the oscillation valley due to the thickness is significantly reduced and almost completely eliminated. I understand. Industrial applicability
- the wall of the mold is opened and closed horizontally with respect to the solidification elbow in accordance with the timing of the longitudinal vibration of the mold (forward and backward).
