- BEST MODE FOR CARRYING OUT THE INVENTION In the mold used in the continuous fabrication of the pellets of the present invention, one or more lateral grooves or a concave portion composed of many dimples is formed on the inner surface of the mold within 200 mm from the lowermost position of the meniscus force. Since they are provided substantially evenly, a gap is forcibly formed between the billet and the mold. Since the inner surface of the mold is tapered so as to gradually decrease downward, the eccentricity of the billet in the mold is prevented, and the heat flux is reduced substantially evenly.
- the heat flux from the molten metal to the ⁇ -type is the largest.
- the magnitude of this heat flux mainly depends on the air gap between the solidification seal and the mold, and the relationship is shown in Fig. 2.
- Fig. 1 (a) is a graph showing the relationship between the heat flux deviation between the billet planes and the rhombic deformation
- Fig. 1 (b) is a diagram showing the rhombic deformation of the billet.
- the means to reduce the heat flux deviation are as follows. Eagya-up portion of the above suitable depth in the lower portion of the look through evenly by the set Keru this (the recess), the magnitude of the heat flux, for example, reduced to 4 million kcalZm 2 hr or al 3,000,000 kcalZn ⁇ hr. (2) Further, the gap between the billet and the mold is reduced by adjusting the mold taper to an appropriate value (for example, the average air gap deviation d, from 20 m). There is a method to reduce the heat flux deviation between the faces of the billet by using the means 1) and 2). Cooled. For this reason, a billet with few defects is manufactured even when manufactured at a high speed (for example, 3.4 m / min).
- the heat flux deviation can be sufficiently reduced by the gentle cooling effect of the artificial air gap (recess), but when the eccentricity of the piece is large, but since the heat flux deviation cannot be reduced, it is preferable to appropriately set the mold taper in the practice of the present invention.
- the slow cooling effect of the air gap in the groove is as shown in FIG. 3 according to the area ratio of the recess and the depth of the groove.
- About 2 to 84% of the concave area ratio is effective in preventing the rhombus deformation. If the area ratio of the recess is smaller than 2%, the heat flux increases, and the temperature deviation of the inner surface of the mold increases as in the conventional technology. If it exceeds 84%, the portion where the solidified seal contacts the mold is increased. And the wear on the inner surface of the mold increases, and the life of the mold decreases.
- the degree of slow cooling is approximately constant at a depth of 0.1 to 0.2 min or more. There is no practical effect even if the depth is increased.
- the shrinkage profile of the solidified shell conventionally has a complicated curve shape in response to a sudden change in heat flux, whereas c) As shown in the figure, it can be approximated to a simple linear shape.
- the gap (air gap) between the shell and the ⁇ type is reduced.
- the inner surface of the ⁇ -type can easily be inserted between the billet and the ⁇ -type.
- the gap between the pieces can be reduced, and the eccentricity of the piece (billette) can be reduced.
- one or more lateral grooves or a large number of dimples forming the concave portion are formed within a range of 200 mm from the lowest position of the meniscus which moves up and down in a normal operation state, this portion is formed.
- a solidified shell is formed, and the molten metal and the concave portion come into contact with each other through the solidified shell.
- the insertion of the molten metal is eliminated, and a sufficiently large groove or a dimple having a sufficiently large diameter than the conventional concave portion can be formed. it can. This also eliminates clogging due to carbon powder as a lubricant.
- the actual operation data is shown in Fig.
- the present invention is of course applicable to powder manufacturing using powder as a lubricant.
- a lateral groove (slit) having an average air gap (recess) depth of 20 tm or more is formed on the inner surface of the mold. .
- the rhombus deformation angle becomes 3 degrees or more. If the depth of the lateral groove is 0.1 mm or more, the heat flux will be stable and the rhombus deformation angle will be 1 degree or less. Therefore, it is preferable to operate in this state.
- the width (W) of the lateral groove is set as in the above equation (1). If the width is 3 or less, carbon powder as a lubricant is clogged in the lateral groove in the steady operation as described above. As a result, the lateral groove disappears, and the diamond deformation angle becomes 3 degrees or more as shown in Fig. 8, resulting in a defective product.
- FIG. 9 (a) is an explanatory diagram of a rectangular oscillation
- FIG. 9 (b) is a diagram illustrating an oscillation. In these figures, because the ⁇ -type 10 is oscillated up and down, the portion of the lateral groove 11 goes up and down, and the width (X) at which the lateral groove is always formed is (W-2a) Becomes.
- the transverse groove 11 formed on the inner surface of the mold 10 is wide, the solidified seal 13 is pushed into the groove by the molten metal 12 that is filled inside the solidified seal 13 and the product It will cause defects. Further, as is clear from FIG. 8, when the value obtained by subtracting the double oscillation stroke (a) exceeds l Oirnn, the rhombus deformation angle becomes 3 degrees or more, and the above (1) If it is determined as in the formula, a billet with a rhombus deformation angle of 3 degrees or less can be continuously formed. In the case of the round and circular ⁇ shapes, the roundness deformation corresponds to 3% or less.
- the average concave depth is 20 mm or less on the inner surface of the ⁇ shape within a range of 200 mm from the lowermost position of the meniscus in a steady operation state.
- the diameter D forms a large number of dimples satisfying the above formula (2), and the numerical limitation is also for the same reason as described above.
- the concave portion is formed by a vertical groove
- the vertical groove is continuously formed in the inner surface of the ⁇ shape in the direction of travel of the solidified shell
- the solidified shell pressed by the molten metal is continuously inserted.
- longitudinal grooves are transferred to the surface of the billet, and as a result, the surface properties of the piece are remarkably impaired, and the billet is susceptible to product defects such as surface cracks or cracks during rolling.
