この発明は連続鋳造において溶鋼等の溶融金属を鋳型に
対して供給するための給湯方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot water supply method for supplying molten metal such as molten steel to a mold in continuous casting.
周知のように連続鋳造法は、鋳型に供給した溶融金属例
えば溶鋼を冷却しつつ連続的に引抜いて鋳片を得る方法
であって、小止りが高く、また多量生産に好適であり、
さらには安価で清浄な鋳片を生産できるので、最近では
鋳造方法の主流となっている。As is well known, the continuous casting method is a method of obtaining slabs by continuously drawing molten metal, such as molten steel, supplied to a mold while cooling it, and has a high stoppage rate and is suitable for mass production.
Furthermore, since it is inexpensive and can produce clean slabs, it has become the mainstream casting method recently.
ところで連続鋳造法におけるタンディツシュから鋳型へ
の給湯の良否は、鋳片の品質や安定操業に大きく影響す
るが、従来では鋳型の上方にタンディツシュを配置し、
溶鋼を自重で鋳型に対して流下させるとともに、タンデ
ィツシュに設けたスライディングノズルによって流量を
制御しているため、以下に述べるような種々の問題があ
った。By the way, the quality of the supply of hot water from the tundish to the mold in the continuous casting method greatly affects the quality of slabs and stable operation, but in the past, the tundish was placed above the mold.
Since the molten steel is caused to flow down into the mold by its own weight and the flow rate is controlled by a sliding nozzle provided in the tundish, there are various problems as described below.
すなわち注入流量制御用スライディングノズルは、その
構造上わずかなりとも隙間を有しているために、注入流

ために、密閉装置を用いることが考えられるが、注入流
を大気から単に遮蔽しただけでは、流量制御を行なえな
くなるなど、未だ解決すべき問題が多々あるのが実情で
ある。That is, since the sliding nozzle for controlling the injection flow rate has at least a slight gap due to its structure, there is a problem in that the atmosphere enters the injection flow through the gap, resulting in oxidation of the molten steel. In order to solve these problems, a method of sealing the injection flow with an inert gas has been considered, but there are many technical problems that need to be solved, and this method has not yet been put into practical use. It is also possible to use a sealing device to prevent oxidation of the injected flow, but the reality is that there are still many problems that need to be resolved, such as simply shielding the injected flow from the atmosphere, making it impossible to control the flow rate. be.
また従来では、鋳型の上方に配置したタンディツシュか

注入流の線速度は、流路断面積を絞ることにより遅くな

その結果鋳片の介在物となって鋳片の品質低下を招来す
るおそれがあった。In addition, in the past, since hot water was supplied to the mold from a tundish placed above the mold, the height from the bath surface in the mold to the bath surface in the tundish was high, and as a result, the linear velocity of the injection flow was considerably high. Become. Conventionally, the cross-sectional area of the flow path was narrowed down using a sliding nozzle in order to match the flow rate of the slab to the feeder tube, and at the same time the cross-sectional area of the immersion nozzle was set to be considerably smaller than the cross-sectional area of the mold. The linear velocity of is not slowed down by narrowing the cross-sectional area of the flow path, so when molten steel with a high linear velocity hits the solidified shell in the mold, that part of the solidified shell melts and a so-called breakout occurs. There was a risk that this would occur. In addition, because the linear velocity of the injection flow is high, the molten steel flow rate is particularly
~ If the flow rate exceeds 2.5 tons/min, the jet from the immersion nozzle entrains mold powder and scum and penetrates deeply into the mold, causing these mold powder and scum to not float to the surface of the mold. is captured in a solidified shell,
As a result, there was a risk that inclusions would form in the slab, leading to deterioration in the quality of the slab.

良を惹起する場合がある。Furthermore, in order to prevent nozzle blockage due to molten steel adhesion near the upper end of the immersion nozzle, inert gas may be blown in using a gas sleeve nozzle, porous nozzle, or gas blowing nozzle. However, in that case, if the linear velocity of the injection flow is high, the inert gas blown into the mold will float to the surface after flowing into the mold with the injection flow, and the meniscus in the mold will be disturbed, resulting in surface defects on the slab. may cause.
さらにまた、注入流を通常の場合とは逆に２．０トン／

が発生するおそれがあった。Furthermore, the injection flow was changed to 2.0 tons/contrary to the normal case.
When casting at a slow linear speed of about 1 minute or less,
In particular, when performing continuous casting of aluminum quilt steel, the conventional method requires reducing the cross-sectional area of the immersion nozzle, which may cause 3-8 F203 to adhere and accumulate inside the immersion nozzle, causing nozzle blockage. Therefore, for example, when continuous casting of a plurality of strands is performed, there is a risk that if any of the discharge ports of the immersion nozzle becomes clogged, a drift of the molten steel will occur, resulting in a breakout.
これに加え、鋳込み速度を速くした場合、従来の方法で
は注入流の線速度が更に速くなるので、上述した問題が
更に顕著になり、鋳込み速度を速くするにも限度があっ
た。In addition, when the casting speed is increased, the linear velocity of the injection flow becomes even faster in the conventional method, so the above-mentioned problem becomes even more pronounced, and there is a limit to how fast the casting speed can be increased.

くすることにより遅くすることができる。Next, a hot water supply method of the present invention using the above-mentioned device will be explained. First, each end of the preheated communicating tube 7 is inserted into the inside of the tundish 1 and the mold 2, respectively, as shown in FIG. 12 and packing ring 13.
Keep sealed as shown. In this state, the molten steel 6 is supplied from the steel drawer 3 to the tundish 1 through the flow rate control device 4 and the long nozzle 5, and the molten steel 6 is fed into the tundish 1.
When the molten steel 6 is filled with molten steel, the ends of the communicating tube 7 are immersed in the molten steel 6, and both ends of the communicating tube 7 are eventually sealed. Therefore, the inside of the communication pipe 7 is vacuum-suctioned by the vacuum bag [10] and, for example, OK! When the pressure is reduced to about +/cIIr, the molten steel 6 in the tundish 1 is sucked up into the communication pipe 7. The pressure inside the communication pipe 7 increases by sucking up the molten steel 6, so after confirming with the pressure gauge 11 that the communication pipe 7 is filled with the molten steel 6, the free end side of the seal plate 12 is suspended. Tetsu I! When the pipe 15 is cut, the end of the communication pipe 7 opens, and the molten steel 6 can flow into the mold 2 according to the siphon principle. As a result of the inflow of the melt 146, the height of the bath surface in the mold 2 is 1
When the bath level in the mold 2 becomes equal to the height, the pressure is balanced, and the flow of the molten steel 6 into the mold 2 stops.When the bath level in the mold 2 decreases as the slab is subsequently pulled out, the pressure balance is changed. Molten steel 6 is supplied into the mold 2 from the tundish 1 via the communication pipe 7 for crumbling. In that case, the inflow linear velocity of the molten steel 6 is:
Since the difference between the bath surface height in the tundish 1 and the bath surface height in the mold 2 is very small, the linear velocity is extremely slow and can be further slowed down by increasing the cross-sectional area of the communicating pipe 7. Even when the speed is increased, the linear velocity of the molten steel flow relative to the mold 2 can be slowed down by making the communication pipe 7 thicker as necessary.

すなわち上記の方法では、鋳片を引き抜くに伴ってその
引き抜き量に応じた量の溶鋼６が鋳型２内に自動的に流

速度によって溶１４流の線速度を決定することになる。That is, in the above method, as the slab is pulled out, an amount of molten steel 6 corresponding to the amount of the pulled slab automatically flows into the mold 2. In other words, the flow line of the molten steel 6 is adjusted depending on the withdrawal speed of the slab. This will determine the speed.

を極めて遅くすることができる。In addition, in the above method, since the difference between the molten steel level in the tundish 1 and the molten steel level in the mold 2 is small, the linear velocity of the molten steel flow is slow, and the cross-sectional area of the communication pipe 7, that is, the molten steel flow path Since the cross-sectional area of the molten metal can be enlarged as necessary, the linear velocity of the molten vA flow can be made extremely low even when the casting speed is increased.

止することができる。As is clear from the above description, according to the hot water supply method of the present invention, a tundish and a mold are arranged adjacent to each other at approximately the same height, and a communicating tube with one end immersed in the molten metal in the tundish is used. By sealing the end, inserting the sealed other end into the mold, and reducing the pressure by vacuum suction inside the communicating tube, the molten metal in the tundish is drawn up and filled into the communicating tube, and then the communicating tube is filled with molten metal. By opening the end of the pre-delivery pipe on the mold side, the molten metal in the tundish is supplied into the mold via the pipe according to the siphon principle, so that as the slab is pulled out, the amount of the drawn slab changes. A proportional flow of molten metal into the mold eliminates the need for a flow control device between the tundish and the mold, thus keeping the injection flow into the mold completely sealed from the atmosphere and preventing its oxidation. In addition, the linear velocity of the injection flow can be reduced to about the drawing speed of the slab by expanding the cross-sectional area of the communication pipe, that is, the flow path cross-sectional area of the injection flow, as necessary. Therefore, it is possible to prevent breakouts and deterioration in slab quality due to the inclusion of mold powder and scum.

行ない得なかった高速度での連続鋳造が可能になる。Furthermore, according to the hot water supply method of the present invention, even if the cross-sectional area of the injection stream is expanded, more molten metal than necessary will not flow into the mold. Even when the casting speed is increased, the linear velocity of the injection flow can be maintained at a low speed. Therefore, according to the hot water supply method of the present invention, continuous casting can be performed at a high speed that has not been possible in the past.
