Embodiment Construction
[0029] The embodiment of the present application provides an online repair method for the lower track of the rotary annealing furnace, which solves the technical problems in the prior art that the maintenance of the ring furnace trolley track is difficult, costly, and complicated to operate; it achieves simplified adjustment operations and improved The technical effect of adjusting efficiency and reducing cost and labor intensity.
[0030] In order to solve the above technical problems, the general idea of the technical solution provided by the embodiment of the present application is as follows:
[0031] By completing the maintenance and adjustment of defective tracks one by one in the gap of the supporting rollers under the track, the adjustment operation is greatly simplified and the efficiency is improved.
[0032] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompany...

The invention belongs to the technical field of annular furnace equipment and discloses an online restoration method for a lower track of a rotary type annealing furnace. The online restoration method for the lower track of the rotary type annealing furnace comprises the steps that a supporting roller set located below the track is leveled, and the vertexes of all supporting rollers are made to be located in the same plane; the track face heights of all long tracks and all short tracks forming the track are measured; the long tracks and the short tracks with the track face heights exceeding the error range relative to the reference height error are screened out and serve as to-be-adjusted tracks; one supporting roller in the supporting roller set below the track is dismantled, and a track adjusting space is formed; a trolley of the rotary type annealing furnace is driven to move, and the to-be-adjusted tracks which are screened out are moved to the track adjusting space; the track face heights of the to-be-adjusted tracks are adjusted; and when adjustment of all the to-be-adjusted tracks is completed, the dismantled supporting roller is installed. The method can conveniently and fast maintain and adjust the track below the annular furnace.
Description
technical field [0001] The invention relates to the technical field of annular furnace equipment, in particular to an online repair method for the lower track of a rotary annealing furnace. Background technique [0002] Annular furnaces, as conventional equipment in the iron and steel field, are widely used in steelmaking production lines, and usually have a load of more than 3,000 tons or even 5,000 tons, which creates continuous pressure on the lower trolley rails. [0003] Due to the continuous pressure of continuous production, the track is forced to deform, and there is a fault in the connection between the long and short tracks to form a height difference, which seriously affects the operation and control accuracy of the trolley, making it unable to run stably and reliably. Oriented silicon steel coils are annealed at high temperature in an annular furnace, and the operation of the rotary trolley is unstable, which brings a series of problems to the stability of orient...
