Failure null transition device for hot-rolling finishing mill

Abstract

The invention belongs to the auxiliary facility of production equipment in metallurgical industry and particularly relates to a failure null transition device for a hot-rolling finishing mill. The transition device comprises an upper mandrel and a lower mandrel, and is characterized in that the upper mandrel is arranged above the lower mandrel; a roller sleeve is respectively sheathed on the uppermandrel and the lower mandrel; the spindle noses of the upper mandrel and the lower mandrel are respectively arranged on a bearing; the bearings are both arranged on bearing pedestals; the bearing pedestal which is provided with the upper mandrel is fixedly installed on a bracket; the bearing pedestal which is provided with the lower mandrel is fixedly arranged on a support; the bracket is fixedly installed on the bearing pedestal which is provided with the lower mandrel, and the upper end of the upper bearing pedestal is provided with an adjusting instrument. When a roll-broken or shaft-broken failure happens to any one mill which runs in a hot-rolling production line, by replacing the mill with failure by the transition device, the roller of the mill with failure can be replaced, and only a few hours are needed for the stopping, dismantling and installation process so as to resume production and transitionally transport strip steel from one mill to the next mill when the mill with failure in running is in a null state.

Description

Technical field: [0001] The invention belongs to the auxiliary facilities of the production equipment in the metallurgical industry, and in particular relates to a transition device for the failure of a hot continuous rolling finishing mill. Background technique: [0002] In the hot rolling production line, there are generally several finishing mills running at the same time. In the continuous production process of hot continuous rolling, if one of the rolling mills in operation breaks a roll or a broken shaft, it will cause a production accident of stacked rolling or stacked steel, and it takes about a week to stop production for maintenance. Invention content: [0003] The invention provides a transitional device for failure of hot continuous rolling finishing mill, the purpose of which is to replace the faulty rolling mill and transfer the strip steel from the previous rolling mill to the subsequent rolling mill when a rolling mill breaks down or a shaft breaks down.
