As a continuous casting machine for hot rolling slabs to reduce their thickness, as disclosed in Japanese Patent Application Laid-Open No. 18201/1983, a continuous casting machine is installed at an appropriate position between the insulation zone of the continuous machine and the cutter outlet. It is known that a heating device is provided at the end of the slab to reduce the amount of heat input. Also, as disclosed in JP-A No. 60-54247, twin belts are used to prevent deflection, and as disclosed in JP-A-60-83747, two drums are used. There are methods that use rotating molds to produce high-temperature slabs and roll them directly without reheating. Are known.

However, in actual continuous casting operations, it is often necessary to reduce the casting speed not only at the start and end of casting but also due to various operating conditions in the next process. Therefore, since the length of the casting section is constant, there is a problem that the temperature of the slab inevitably decreases in such a case.

As the slab 15 moves in the direction, the slab 15 descends, and when it reaches the position of the belt guide roller 11 at the maximum casting speed, the molten metal 12 solidifies to the center inside the slab 15. If the molten steel is not solidified at the center of the inside of the slab 15 even after the guide roller 11, a large static pressure is acting on the inside of the slab 15, and the slab 15 will bulge due to this static pressure. It is designed to. Therefore, the hottest slab 15 is obtained at the maximum speed. The slab 15 after casting is bent by bending rollers 16, re-bent by straightening rollers 17, and then rolled to a predetermined product thickness by a rolling mill (not shown) in the next step.

A mold release agent 18 is applied before contacting the mold. Rapeseed oil, silicone oil, carbon-based soot, or the like is used as the mold release agent 18. The mold release agent 18 is mixed with N 2 and Ar gas, and the atomized state is pumped from the header pipe 19 through the nozzle 20. The mold release agent layer 24 is formed by spraying onto the belt 1 with a pressure of 22. The thickness of the mold release agent layer 24 is adjusted by adjusting the variable discharge pump 22 based on commands from the control panel 23 to control the amount of mold release agent.

め、それ自体が熱抵抗大であり熱移動を抑制す
る。 Next, the operation of this embodiment will be explained. Among the mold release agents 18 interposed between the mold wall surface and the solidified shell surface of the slab 15, especially oil-based agents are generally decomposed into fine particles by the high temperature action of the slab 15 and adhered to the mold wall surface. Therefore, an air film corresponding to the thickness of the initially applied mold release agent is present between the mold wall surface and the solidified shell surface, resulting in thermal resistance. Furthermore, since the molten powder is mainly composed of SiO 2 , CaO 3 , Al 2 O 3 and the like, it itself has high thermal resistance and suppresses heat transfer.
離型剤の厚みをｓ、空気膜あるいはパウダの熱
伝導率をλとすれば、熱移動係数はＫ＝λ／ｓと
なる。空気膜が形成される離型剤では、
λ＝0.03Kcal／mhr℃であるから、離型剤の厚
みを10μｍ程度にとれば、
Ｋ＝3000Kcal／m2hr℃となる。 If the thickness of the mold release agent is s, and the thermal conductivity of the air film or powder is λ, then the heat transfer coefficient is K=λ/s. For a mold release agent that forms an air film, λ = 0.03 Kcal/mhr°C, so if the thickness of the mold release agent is set to about 10 μm, K = 3000 Kcal/m 2 hr°C.
パウダでは概略λ＝0.1Kcal／mhr℃であるか
ら、この厚みを33μｍにすれば、
Ｋ＝3000Kcal／m2hr℃となる。 For powder, λ = approximately 0.1 Kcal/mhr°C, so if this thickness is set to 33 μm, K = 3000 Kcal/m 2 hr°C.
すなわち、熱移動係数Ｋは離型剤厚みに比例し
て変化する。一方鋳型での鋳片凝固区間Ｌは一定
であるから、鋳造速度ｖに反比例して鋳型内での
冷却時間ｔが決まる。すなわちｔ＝Ｌ／ｖとな

型剤の厚みを大の方向に調整してゆき、鋳型内の
鋳片が冷えすぎないようにし、常時高温の鋳片を
製造することを可能にするものである。 That is, the heat transfer coefficient K changes in proportion to the thickness of the mold release agent. On the other hand, since the slab solidification interval L in the mold is constant, the cooling time t in the mold is determined in inverse proportion to the casting speed v. That is, t=L/v. The longer the cooling time t, the colder the slab becomes, so in this case, the heat transfer coefficient K is made smaller. In other words, it can be seen that it is sufficient to increase the thickness s of the mold release agent. For the above reasons, cooling of solidification heat in a mold with a fixed cooling length is based on casting at the highest speed, and as the speed becomes slower, the thickness of the mold release agent is adjusted to increase. This prevents the slab in the mold from getting too cold, making it possible to produce slabs that are constantly hot.

加熱することなく直接圧延することが可能であ
る。 For example, in the continuous casting machine shown in Fig. 1, the thickness of the slab 15 to be cast is 20 to 50 mm, and the plate width is 700 to 1600 mm.
mm, and the maximum casting speed is generally 10 to 20 m/min. The mold cooling length is 3000 to 4000 mm. When casting at such high speeds, the temperature of the slab at the exit side of the mold is approximately 1150°C at the maximum casting speed when casting steel materials.
With conventional manufacturing methods, the casting speed is 50% of the maximum
When the speed decreased, the slab temperature decreased by about 200°C, but by adjusting the thickness of the mold release agent layer 24 according to this example, the slab temperature was almost the same as that at the maximum speed, and there was no need to reheat it. In other words, the temperature required for hot rolling is 1000℃ at the entrance of the rolling mill, and the temperature required for hot rolling is 150℃, which is the temperature of the slab that is 1150℃ at the mold exit as shown in Figure 1. ℃, so it is possible to roll directly without reheating.

る。 FIG. 2 shows a second embodiment in which a mold release agent is applied using a roll coater method. In this method, the mold release agent 18 contained in the tank 25 is rotated in the direction of arrow B.
Belt 1a is passed through a pair of coater rolls 26 and 27.
In this method, a mold release agent layer 24 is formed by coating the upper surface of the mold release agent layer 24. In this case, the thickness of the mold release agent layer 24 is adjusted by adjusting the rotational speed of the coater rolls 26 and 27.

い。 Each of the above-mentioned embodiments has been explained using a twin-belt type continuous casting machine.
It can also be applied when using a twin-drum type continuous casting machine as shown in Publication No. 83747, and has the same effect. In this case, the thickness of the mold release agent layer formed on the drum surface may be adjusted by adjusting the mold release speed. In addition, in the case of a fixed mold, the amount of mold release agent powder to be supplied is adjusted. However, in the case of the fixed mold method, the thickness of the slab to be cast is relatively thick, and since the slab is mainly cooled by spray cooling after leaving the mold, the thickness of the mold release agent layer is Controlling the holding temperature by adjustment has little effect.

As described above, according to the present invention, when producing high-temperature slabs using a continuous casting machine, the thickness of the release agent layer is adjusted in almost inverse proportion to the casting speed, so that the casting speed is reduced. Also, the temperature of the slab on the exit side of the mold can be maintained at a high temperature.
