Abstract
The invention discloses a method for controlling a safety protection device of a walking beam of a heating furnace. The safety protection device is arranged at the tapping position of the heating furnace and provided with a steel billet detector (2) which is connected with a control system of the heating furnace. The control system is provided with a computer input and output device. By the adoption of the technical scheme, according to the safety interlock technology of the walking beam of the heating furnace, a tapping heat detector or a laser detector is utilized, or another detector is additionally arranged, 'steel gain' and 'steel loss' signals are detected through tapping heat detection, safety of the walking beam of the heating furnace is guaranteed, and the problem that two-stage control needs to be developed in most heating furnaces is solved.
Description
Technical field
The invention belongs to the technical field of metallurgical industry production equipment.Specifically, the present invention relates to a kind of heating furnace step rate safety guard and control method thereof.
Background technology
In the prior art, large-scale walking beam furnace adopts overhang roll technology to take on steel, often due to overhang roll deposit steel or due to extremely cause tapping stop, cause hanging arm roll to store steel billet, make upper while once moving, when step rate advances, steel billet is hit in beam butt, causes water beam pad block in high temperature furnace to come off, and forms the serious accident stopping production.
Summary of the invention
The invention provides a kind of heating furnace step rate safety guard and control method thereof, its objective is the safety that guarantees heating furnace step rate.
To achieve these goals, the technical scheme that the present invention takes is:
Heating furnace step rate safety guard of the present invention, in the position of coming out of the stove of heating furnace, arranges steel billet detector, and described steel billet detector is connected with the control system of heating furnace; Described control system is provided with input output device of computer.
Described steel billet detector adopts laser detector.
Described input output device of computer is the interactive display device of touch-screen.
In order to realize the goal of the invention identical with technique scheme, the control method that the present invention also provides above-described heating furnace step rate safety guard to adopt, its technical scheme is:
Walk a direct circulation at every turn, all give tacit consent to a steel billet and be put into discharging cantilever;
If steel billet detector " come out of the stove heat inspection " does not detect " steel " and " mistake steel " signal, think that this steel billet still on discharging cantilever, forbids next time " wanting steel " and direct circulation, computer display apparatus ejects points out:
" after please steel billet on discharging cantilever being come out of the stove, again ' want steel ', or be confirmed to be ' empty step pitch in batches ' ";
If steel billet detector " come out of the stove heat inspection " detects discharging cantilever, there is steel billet, on computer display apparatus, click after " having steel ", by operating personnel manually after tapping, then carry out " wanting steel "; Otherwise, forbid " wanting steel ";
If worker clicks " empty step pitch in batches ", can start direct circulation.
The present invention adopts the safety interlocking technology of the heating furnace step rate of technique scheme, the heat inspection (or laser detector) that utilization is come out of the stove, an or newly-increased detector, by " heat of coming out of the stove inspection ", " obtaining steel " and " mistake steel " signal detected, guarantee the safety of heating furnace step rate, solved most of heating furnace and need to develop the difficult problem that secondary is controlled.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, be labeled as:
1, steel billet in stove, 2, steel billet detector.
The specific embodiment
Contrast accompanying drawing below, the description by embodiment, is described in further detail the specific embodiment of the present invention, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present invention, technical scheme.
Structure of the present invention as shown in Figure 1, is a kind of heating furnace step rate safety guard, relates to the resist technology of the safety interlocking of heating furnace step rate.
In order to solve the problem of prior art existence and to overcome its defect, realize the goal of the invention of the safety that guarantees heating furnace step rate, the technical scheme that the present invention takes is:
As shown in Figure 1, heating furnace step rate safety guard of the present invention, in the position of coming out of the stove of heating furnace, arranges steel billet detector 2, and described steel billet detector 2 is connected with the control system of heating furnace; Described control system is provided with input output device of computer.
The heat that utilization of the present invention is come out of the stove is examined (or laser detector) or is increased one newly, by " heat of coming out of the stove inspection ", steel and mistake steel signal detected to obtain, by come out of the stove detection and step rate, in conjunction with guaranteeing step rate safety, solved the difficult problem that most of heating furnace need to be developed secondary.
Described steel billet detector 2 adopts laser detector.
When existing above overhang roll due to abnormal steel billet, avoid step rate misoperation and workman's maloperation, and produce pernicious production accident.Greatly improved heating furnace step rate security performance.
Described input output device of computer is the interactive display device of touch-screen.
Walk a direct circulation at every turn, all give tacit consent to a steel billet and be put into discharging cantilever, as " heat of coming out of the stove inspection " do not detect to obtain steel and mistake steel signal, think that this steel billet is still at overhang roll, forbid wanting steel and direct circulation next time, display device ejects prompting " medicine steel again after please overhang roll steel billet being come out of the stove, or be confirmed to be empty step pitch in batches "
If overhang roll has steel billet, on display device, click and have after steel, after manually being tapped by worker, then row is wanted steel.Otherwise forbid wanting steel.If worker clicks " empty step pitch in batches ", can direct circulation.
In order to realize the goal of the invention identical with technique scheme, the control method that the present invention also provides above-described heating furnace step rate safety guard to adopt, its technical scheme is:
Walk a direct circulation at every turn, all give tacit consent to a steel billet and be put into discharging cantilever;
If steel billet detector 2 " come out of the stove heat inspection " does not detect " steel " and " mistake steel " signal, think that this steel billet still on discharging cantilever, forbids next time " wanting steel " and direct circulation, computer display apparatus ejects points out:
" after please steel billet on discharging cantilever being come out of the stove, again ' want steel ', or be confirmed to be ' empty step pitch in batches ' ";
If steel billet detector 2 " come out of the stove heat inspection " detects discharging cantilever, there is steel billet, on computer display apparatus, click after " having steel ", by operating personnel manually after tapping, then carry out " wanting steel "; Otherwise, forbid " wanting steel ";
If worker clicks " empty step pitch in batches ", can start direct circulation.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
