Abstract

The invention provides a steel rolling heating furnace charging blank length measurement alarm method and device. The method comprises the steps that a furnace blank steel feeding signal is obtained;according to the furnace blank steel feeding signal, a metal detector and an encoder are controlled to operate, and output results including a first distance actual measurement value and a second distance measurement value of a furnace blank are obtained; a first distance set value is obtained; a first error value is calculated according to the first distance actual measurement value and the firstdistance set value; a second error value is calculated according to the second distance measurement value of the furnace blank, the first distance set value and the first error value; a total error value is obtained according to the first error value and the second error value; an error setting threshold is obtained; and the alarm information is obtained according to the total error value and theerror setting threshold. The technical problems that a method used in the prior art is large in measurement value error, false alarm is likely to be generated, and the production rhythm is influencedare solved. The technical effects that the length detection result is more accurate, the accuracy of alarm information is ensured, and the false alarm rate is effectively reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of detection and control of the length of billets entering a furnace in a steel rolling heating furnace, in particular to a method and device for measuring and alarming the length of billets entering a furnace in a steel rolling heating furnace. Background technique [0002] The heating furnace billet used in the rolling workshop will basically have length inspection and control. After the design of the heating furnace is completed, the furnace length, width, height and other data have been determined. Therefore, there are strict control requirements for the length of the furnace billet. If If the billet is too long, it will not only scratch the furnace wall, but also when it is in the furnace for a long time, due to the design of the movable beam and the fixed beam in the furnace (their position and the movable area are fixed), one or both ends of the billet will be too long. If the billet is bent, it will ...
