Definitions
- the invention relates to a device for lateral Guiding a casting strand with a rotatably mounted Roller body by a cone-shaped roller holder is worn.
- Such devices are in Continuous casting machines for lateral guidance of the Metal strands used.
- the reel body rolls in direct contact with the hot strand on this from.
- the roller body and all with elements connected to it are strongly heated. So is the typical operating temperature in known Guide devices up to 500 ° C.
- Guide devices are known from practice.
- the advantage of the known guide devices consists in their simplicity and the associated minor Manufacturing costs. Because of this, they have been around for a long time and in large numbers at continuous casting plants used.
- a disadvantage of the known guide rollers is however, that to be repeated at short intervals Relubrication of the plain bearing at high maintenance costs leads.
- a device for guidance of a casting strand known with a gear wheel driven lowering roller is equipped.
- the Lowering roller and the gear wheel are each on one End of a shaft attached in the area of each end an open warehouse is stored.
- To cool the Shaft and the lowering roller becomes a coolant through a bore formed in the shaft in a cavity passed, which is formed inside the lowering roller.
- Shaft coolant that gets into the cavity there by the heat given off by the guided strand heated so much that it begins to evaporate.
- Which Forming steam reaches a through a cover plate Nozzle opening, through which it remains vaporous or in the form of a stranded one Liquid jet escapes into the environment.
- the nozzle opening works like a pressure relief valve, which the Coolant leaks from the lowering roller Enclosed space once the pressure is inside this space due to the warming of the Shaft coolant associated volume increase of Coolant has risen so much that heated Coolant is pressed out of the nozzle.
- the object of the invention is a Guide device of the type mentioned create a longer with less maintenance Has life expectancy.
- roller body in one piece train with the roll holder.
- optimal material pairings be advantageous to design the roller body in such a way that it can be plugged onto the end section.
- the roller body at least has a space through which the coolant can flow is. This space should advantageously be coaxial extend to the end portion.
- the invention is based on a Exemplary embodiment drawing closer explained.
- the only figure shows one on one Continuous casting machine used guide device in Cut.
- the guide device 1 has a housing 2, the Wall 3 surrounds an interior 4. On the inside of the Wall 3 is formed in the middle of a circumferential paragraph 5 whose shoulders each have a spherical roller bearing 6.7 "For life lubrication" is supported.
- a pin-shaped Roll holder 8 stored with his one End section 8a freely from one on the upper end face 2a of the housing 2 protrudes opening, while its other end portion 8b comes out of an opening the lower end face 2b of the housing 2 is guided.
- the Openings on the upper and lower end faces 2a, 2b of the Housing 2 are each one by one Shaft seal 9.10 bearing cover 11.12 opposite acting on the housing from the outside Dirt sealed.
- a roller body 13 On the first end portion 8a of the roll holder 8 a roller body 13 is attached.
- the room 14 has a larger diameter than the outer diameter of the end portion 8a of the Roll holder 8 by one on the lower end face 13b of the roller body 13 formed through the opening Room 14 into one in the upper end face 13a molded opening of the roller body 13 is guided.
- room 14 is through Sealed roller holder 8 adjacent O-rings 15, which in in the edges of the openings of the roller body 13 trained ring grooves.
- the opening of the top The end face 13a of the roller body 13 is additionally tight closed by a lid 16.
- the roller body 8 has two bores 8c, 8d which from the lower end of the lower end portion 8b to extend approximately to the tip of the end portion 8a.
- Each of the bores 8c, 8d is radial over itself extending connection bore 8e or 8f with the space 14 of the roller body 13 connected, the Connecting hole 8e between the first hole 8c in Region of the tip of the end section 8a is arranged, while the connecting hole 8f between the second Bore 8d and the space 14 of the lower end face 13b of the Roll body 13 is assigned.
- the holes 8c, 8d are in a manner known per se with a fixed arrangement Coolant supply line Z and one Coolant discharge line A via a rotationally decoupled Two-way rotary joint connected like them is described for example in DE-OS 2 315 865.
- the coolant flows through the coolant supply line Z in the hole 8c and passes through the connecting hole 8e into room 14. From here it flows over the Connecting hole 8f in the hole 8d and from there in the coolant discharge line A.
- the corresponding one Flow path S is through the dashed line in the Figure indicated.
