Abstract
The invention discloses a method for accurately positioning a charging basket for roller-hearth continuous annealing furnaces, which belongs to a charging basket positioning method. The method is implemented as follows: an encoder is additionally arranged on a driven roller of a roller way at the heating section of a roller-hearth continuous annealing furnace, and achieves length counting and positioning functions and is arranged on the driven roller of the roller way, and the moving length L1 of the charging basket is calculated according to the number of rotating circles of a roller wheel and the perimeter of the roller wheel; and a high-speed counting module is additionally arranged in a PLC (programmable logic controller) configuration, in a program, the actual distance from the previous-area purging position to the next-area purging position is set as L2, when a condition that L1 is equal to L2 is satisfied, the roller way drives a motor to stop running, and the positioning of the charging basket is completed. After the charging basket runs to a positioning position, the charging basket automatically stops, thereby achieving the purpose of completely purging protective gas. The method for accurately positioning a charging basket for the roller-hearth continuous annealing furnaces disclosed by the invention has the characteristics of no lampblack interference, high stability and capability of increasing the quality of products, and therefore, the method has good popularization and application values.
Description
Technical field
Patent of the present invention and a kind of charging basket localization method, especially a kind of roller-hearth continuous annealing furnace charging basket accurate positioning method.
Background technology
copper pipe uses roller-hearth continuous annealing furnace to anneal in finished products workshop section usually, copper pipe is transferred to FX by positioning control system and heats in charging basket, annealing and cooling, what traditional charging basket positioning control system material adopted is the correlation type grating, shading light electric switch when charging basket is delivered to the position location by roller-way, this signal is transferred to the roller-way drive-motor by PLC and realizes charging basket location, it is larger that the heating zone copper pipe purges the flue gas that causes, easily blocking the correlation type grating and producing flase operation causes charging basket to stop in advance, charging basket location is inaccurate causes the purge position location inaccurate, purge unsuccessfully, cause copper pipe off quality.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to provide a kind of roller-hearth continuous annealing furnace charging basket accurate positioning method for above-mentioned deficiency of the prior art, and this roller-hearth continuous annealing furnace charging basket accurate positioning method has characteristics such as improving the quality of products, be not subjected to oil smoke interference, high stability.
Patent of the present invention solves the technical scheme that its technical problem adopts: increase encoder on roller-hearth continuous annealing furnace heating zone roller-way driven roll, encoder is realized the long positioning function of note, be installed on the roller-way driven roll, the distance L 1 that the number of turns of rotating according to running roller and the circumference calculating charging basket of running roller move, increase high speed counting module in the PLC configuration, on setting in program, a regional purge position is to the actual range L2 of next regional purge position, when the L1=L2 condition satisfies, the roller-way drive-motor is out of service, and charging basket is located and completed.Automatically stop after making charging basket run to the position location, thereby reach the purpose that purges fully of shielding gas.
Compared to the prior art a kind of roller-hearth continuous annealing furnace charging basket accurate positioning method of the present invention has following outstanding beneficial effect: improve the quality of products, be not subjected to the characteristics such as oil smoke interference, high stability.
Embodiment
A kind of roller-hearth continuous annealing furnace charging basket accurate positioning method of the present invention is described in detail below.
a kind of roller-hearth continuous annealing furnace charging basket accurate positioning method of the present invention, its technical parameter requires: increase encoder on roller-hearth continuous annealing furnace heating zone roller-way driven roll, encoder is realized the long positioning function of note, be installed on the roller-way driven roll, the distance L 1 that the number of turns of rotating according to running roller and the circumference calculating charging basket of running roller move, increase high speed counting module in the PLC configuration, on setting in program, a regional purge position is to the actual range L2 of next regional purge position, when the L1=L2 condition satisfies, the roller-way drive-motor is out of service, complete the charging basket location.Automatically stop after making charging basket run to the position location, thereby reach the purpose that purges fully of shielding gas.
For guaranteeing the reliability of encoder and grating positioning, be provided with the prerun time T according to the time of charging basket actual motion in program, adopt the note long number value of encoder to determine signal for locating before T arrives, avoided like this oil smoke signal to cause the location too early to the interference of grating.Adopt grating signal to determine signal for locating after T arrives, avoided loosening grade of encoder coupling to cause the excessively slow problem in location.This method is carried out test of many times at our factory, has found optimum controling method.At present, apply in production practice.
Except the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
