Abstract
The utility model designs a front roller way device of a tension reducing mill of seamless steel pipes and a front roller way device of a sizing mill and comprises a roller way base, a lifting device of a roller way, a roller way bracket and way roller devices, wherein the lifting device of the roller way is installed between the roller way base and the roller way bracket; a plurality of way roller devices are equidistantly installed on the roller way bracket; a roller on each of the way roller devices is driven to rotate by an independent motor. The utility model is characterized in that an extending bracket is installed in front of the roller way bracket; a power-free driven guiding roller device is arranged in front of the extending bracket; the extending bracket position behind the guiding roller device is provided with a descaling device. The descaling device and the tension reducing mill of seamless steel pipes and a front roller way device of a sizing mill are integrally designed and manufactured. The utility model has the advantages of easy adjustment, easy positioning, convenient installation and good guiding quality; besides, the utility model solves the problem that a crude pipe after descaling sideslips, when entering the tension reducing mill or the sizing mill and the front roller way device.
Description
Technical field
The utility model belongs to seamless steel pipe production, relates to the front roller-way device that reaches seamless steel pipe stretch-reducing mill or sizing mill particularly.
Background technology
At present, in smelter seamless steel pipe rolling production equipment, stretch-reducing mill and sizing mill are the crucial finishing equipments of seamless steel pipe rolling production.The hollow forging that tandem rolling tube machine shuts out behind the descaling device high-pressure water descaling, is carried hollow forging and import stretch-reducing mill or sizing mill by the front roller-way device again.Existing descaling device is independent the installation before the front roller-way device, and with front roller-way Unit Installation onrelevant.Therefore, Installation and Debugging at equipment, and the hollow forging that usually takes place in the steel pipe's production after the de-scaling is entering stretch-reducing mill or sizing mill, and preliminary roller deviation phenomenon when leading duct device, so that hollow forging can not enter the finishing of carrying out tube reducing and sizing in stretch-reducing mill or the sizing mill smoothly, and influences seamless steel tube production.
Summary of the invention
The deficiency that the purpose of this utility model exists at above prior art, project organization are simply compact, easily install and adjust and the location, and guidance quality is good, reliable operation, the seamless steel pipe stretch-reducing mill of band descaling device or the front roller-way device of sizing mill.
The technical solution of the utility model is achieved in that
The front roller-way device of seamless steel pipe stretch-reducing mill or sizing mill, comprise the roller-way base, the roller-lifting device, the roller-way support, the road roller arrangement, the roller-lifting device is loaded on the roller-way base between roller bed frame, has several road roller arrangements to be loaded on equally spacedly on the roller-way support, and the roller that is driven on it by an independent electric motors on each road roller arrangement rotates; It is characterized in that: an extension support is installed before the roller-way support, and a unpowered guide reel device is equipped with in the front of extending support, the extension support place dress descaling device behind the guide reel device.
The seamless steel pipe stretch-reducing mill of the utility model design or the front roller-way device of sizing mill compared with prior art, comparatively outstanding substantive distinguishing features and technological progress are: it will be with the global design of front roller-way device and the manufacturing of descaling device and seamless steel pipe stretch-reducing mill or sizing mill.Easily adjust and the location, easy for installation, guidance quality is good, has solved the hollow forging that occurs in after the de-scaling and has entered stretch-reducing mill or sizing mill, and the problem of preliminary roller deviation phenomenon when leading duct device.
Description of drawings
