Problems solved by technology
Due to the slippage of the billet when traveling on the roller table, the wear of the roller table, the inconsistent speed of the encoder roller / non-encoder roller, etc., the accuracy of this method is poor, especially the longer it is put into use, the lower the accuracy, and it cannot meet the increasing length of the industry. , centering requirements

Embodiment Construction
[0026] Such as figure 1 As shown, the inner width of the furnace is set to W, the distance between the metal detector 1 and the center line of the furnace is set to L1, the distance between the laser range finder 2 and the center line of the furnace is set to L2; The detector 1 and the laser range finder 2 are connected with the signal processing and control system; it is characterized in that the laser range finder 2 is set at the center line extension of the left end of the furnace feed roller table at a distance from the furnace feed roller table. On the line, the detection surface of the laser range finder 2 is opposite to the moving direction of the billet head end.
[0027] When the metal detector 1 scans the head of the billet 3, the length between the first end of the billet and the laser range finder 2 is Ld1, the signal processing and control system obtains the rising edge signal sent by the metal detector 1, and records the laser range finder 2 The measured length ...

The invention relates to a steel blank length-measurement positioning system, which belongs to the field of a steel bank entering furnace system, and comprises an end part detector, a distance detector and a signal processing and control system, wherein the end part detector is arranged at the outer side of an entering furnace roller way, and the end part detector and the distance detector are respectively connected with the signal processing and control system. The steel blank length-measurement positioning system is characterized in that the distance detector and the entering furnace rollerway are arranged at either the left end or the right end of the entering furnace roller way at intervals and are positioned on the extending line of the center line of the corresponding end of the entering furnace roller passage. The steel blank length-measurement positioning system can be used for precisely measuring the steel blank length and completing the steel blank entering furnace aligning, so the centering arrangement of steel blanks in a furnace in the furnace width direction is ensured, the load of a support component in the furnace is uniform, the distances from both ends of the steel blanks to the furnace walls of the two sides are identical, the accidents such as deflection wall collision and the like can be reduced to the maximum degree, the adopted equipment is simple, the use range is wide, the steel blank length-measurement positioning system is applicable to the new building or reformation of various heat treatment furnaces and steel milling heating furnaces with precise steel blank length-measurement and aligned entering furnace requirements, the investment is low, the construction period is short, and the equipment maintenance is simple.
Description
technical field [0001] The invention relates to a billet charging system, in particular to a control system for measuring, positioning and centering a billet in front of various continuous steel rolling heating furnaces and heat treatment furnaces. Background technique [0002] For various steel rolling heating furnaces and heat treatment furnaces in steel plants, especially continuous steel rolling heating furnaces and heat treatment furnaces, it is usually necessary to arrange the steel billets in the center along the furnace width direction in the furnace, so that the load of the supporting members in the furnace is even. The distance between the furnace walls on both sides is equal to minimize accidents such as running off and hitting the wall. At the same time, in order to calculate the production capacity of the heating furnace, it is necessary to accurately measure the length of the billet. In order to achieve this goal, it is necessary to complete the length measure...
