专利汇可以提供Apparatus for cooling a continuous casting mould专利检索，专利查询，专利分析的服务。并且The invention relates to an apparatus for cooling a continuous casting mould, comprising a cooling water supply conduit, an emergency cooling water supply conduit and a cooling water return conduit, all three conduits being joined to an overhead container which for its greatest part is filled with boiler feed water. At the upper part of said overhead container a space filled with a pressurized fluid is provided forming an elastic pressure cushion to protect the overhead container and all conduits from corrosion and boiler scale.，下面是Apparatus for cooling a continuous casting mould专利的具体信息内容。

权利要求

1. An apparatus for cooling a continuous casting mould comprising a casting mould a closed container, the container being positioned above the casting mould and being at least partially filled with cooling water, a pressurized inert gas in the container forming an elastic pressure cushion above the cooling water, a first supply conduit from the container to the casting mould, a return conduit from the casting mould to the container, pump means for supplying the cooling water in the container to the casting mould and returning the water from the casting mould to the container, flow regulating means for providing a predetermined amount of water to the casting mould, temperature regulating means for maintaining the temperature of the water in the casting mould at a predetermined temperature, a second supply conduit from the container to the casting mould, and valve means connected to the second supply conduit and adapted to be opened only when the pump fails, the container, conduits, and casting mould being sealed from the atmosphere forming a primary and emergency closed cooling circulation system.

2. The apparatus set forth in claim 1 further comprising a tank and a connecting conduit, the tank at least partially filled with water, having a water supply conduit and a water level regulating means, and the connecting conduit in communication with the water in the tank and the inert gas in the closed container.

3. The apparatus set forth in claim 1 wherein the inert gas is nitrogen.

4. The apparatus set forth in claim 1, wherein the pressure cushion is adjustable to a pressure of 0.3 to 0.4 atmospheres gauge.

5. The apparatus set forth in claim 1, wherein in said closed container, a cylindrical vessel is provided which is closed at its lower end by a bottom and open at its upper end, and the return conduit ends in the vicinity of said bottom within said cylindrical vessel.

6. The apparatus set forth in claim 1, wherein the second supply conduit is branched off the closed container and joined to the continuous casting mould at sites having a level difference between each other of at least 5 m.

7. The apparatus set forth in claim 1, wherein the inert gas is connected via a connecting conduit to a water tank and each of said closed container and said water tank is provided with a level regulating means and a water supply conduit with a level regulating valve.

8. The apparatus set forth in claim 1, wherein a heat exchanger is provided in the first supply conduit.
