Embodiment 1

[0038] see now figure 1 , figure 1 It is a schematic diagram of the central line positioning control of the embodiment of the present invention. As shown in the figure, the centerline 1 is parallel to the centerline 2 of the unit.

[0039] The method for controlling the installation accuracy of the centralized transmission roller table of the oriented silicon steel annealing furnace of the present invention is characterized in that it comprises the following steps:

[0040] a. Centerline positioning control

[0041] Before the installation of the annealing furnace, along the length direction of the annealing furnace, set an auxiliary center line support at every 30m intervals at the position close to the furnace shell on the transmission side of the furnace, and run through the entire annealing furnace; The deviation caused by the swaying of the wire is too long.

[0042] b. Centralized transmission roller table adjustment control

[0043] figure 2 It is a schematic dia...

Abstract

A control method of installation precision of a centralized transmission roller table of an oriented silicon steel annealing furnace is disclosed; and the control method is characterized by comprising the following steps: a) positioning control of a center line, b), adjusting control of the centralized transmission roller table, c), control for preventing roller constraint, d) checking control of a furnace roller flange and e) inspection of installation effect of the centralized transmission roller table. The control method of the installation precision of the centralized transmission roller table of the oriented silicon steel annealing furnace has the advantages that: the step of adjusting control is reasonable in design and simple to operate, the installation construction time is shortened, the installation precision of the roller table of the furnace body can be effectively improved, the run deviation of product running can be within 10mm, and the method passes thermal state production examine, has no blocking phenomenon, greatly extends the use and the maintenance cycle of the roller table, can ensure the control of the run deviation of strip steels, and can fully meet the use requirements of production.

Description

technical field [0001] The invention relates to a method for controlling the installation accuracy of a roller table, in particular to a method for controlling the installation accuracy of a centralized drive roller table for an oriented silicon steel annealing furnace. Background technique [0002] The continuous decarburization annealing unit for oriented silicon steel is a modern production line, and its final product is oriented silicon steel, which is widely used in the electrical field. The horizontal annealing furnace is 345m long, 3m high, 2.8m wide, and has 232 roller tables, with an average of 1.5m per roller. Road, mainly installed on the 8.5m platform. The installation of annealing furnace is characterized by long installation period, many construction procedures, heavy installation workload and large labor input. The furnace body equipment of the annealing furnace is basically supplied in spare parts, the on-site assembly workload is large, and the installation...
