Large section steel billet girder type heating furnace bottom stepping device

Abstract

The invention relates to a large section steel billet girder type heating furnace bottom stepping device which is characterized by consisting of a translation framework, an elevating framework, translation rolling wheels, elevating rolling wheels, inclined guide rail seats, translation and elevating framework lateral positioning guide wheel groups, elevating drive devices, and translation drive devices, wherein the translation rolling wheels and the elevating rolling wheels are arranged on an installation face of the elevating framework, the center lines of the translation rolling wheels and the center lines of the elevating rolling wheels are superposed and a lead hammer is suspended above the floor, the vertical direction running distance of each of the translation framework and the elevating framework is 220 mm, and the horizontal direction running distance of the translation framework ranges between 0 to 350 mm. The large section steel billet girder type heating furnace bottom stepping device solves the problem that a large section steel billet, particularly a phi600 round steel billet which is 12 meters in length, is an excessive steel load to be heated in a stepping girder type heating furnace. The large section steel billet girder type heating furnace bottom stepping device is characterized by large rigidity, simple and compact transmission structure, convenience of manufacture and installation, convenience of maintenance and overhaul, and the like. The large section steel billet girder type heating furnace bottom stepping device is also advantaged by small number of moving parts, good interchangeability, small number of spare part kinds, and greatly reduced daily point inspection and maintenance and overhaul work.

Description

technical field [0001] The invention belongs to production process equipment in the field of hot rolling and heat treatment, and relates to a walking mechanical facility for a steel billet with a diameter of 600 round and 12 meters in size for a beam-type heating furnace, in particular to a walking device for a furnace bottom of a large-section billet beam-type heating furnace. Background technique [0002] Recently, the demand for alloy steel, bearing steel, and large-diameter thick-walled alloy steel pipes in the domestic and international markets has been increasing, especially the demand for large-section alloy steel and bearing steel. Improve business performance and profitability. At present, domestic enterprises generally reduce the length of large-section billets, or shorten the length of heating furnaces, to solve the problem of excessive steel loading in heating furnaces in hot rolling workshops, and at the same time configure multiple heating furnaces to meet the ...

AI Technical Summary

Problems solved by technology

[0003] The present invention overcomes the above-mentioned defects, and aims to solve the problem of large-section steel billets, especially 12-meter-long Φ600 round steel billets, in the walking beam heating furnace for heating through steel, and realizes that the construction of a heating furnace can meet the rolling requirements. According to the line rolling rhythm and production capacity requirements, while saving land, reducing labor force, reducing maintenance burden and reducing operating costs, it can also improve the investment and social benefits of the enterprise, and provide a large-section billet beam heating furnace bottom walking device
