Problems solved by technology
Therefore, in the process of research on walking beam control methods and control equipment development, it is impossible to have a real walking beam system as the control object to conduct experiments to test the control effect; in the process of project implementation, often due to tight schedules and heavy tasks, The debugging time that can be given is extremely short, coupled with the differences in design capacity, production process, etc., it is difficult to obtain a very satisfactory control effect for each walking beam with different parameters
At present, the control of walking beams in China still adopts an open-loop method, and production is often interrupted due to the inability to guarantee control accuracy.

Embodiment Construction
[0057] Such as figure 1 As shown, the walking beam is composed of a fixed beam 3 and a movable beam 2. The fixed beam 3 supports the billet 1, and the movable beam 2 can lift the billet 1 forward. The movable beam 2 and the horizontal frame 4 are combined together. 2 When it rises to the level of the fixed beam 3, it touches and holds up the billet 1.
[0058] When the moving beam 2 is running, it has a process of ascending, descending, forwarding and retreating. Although the structure of these process mathematical models is basically the same, there are certain differences in parameters due to the asymmetry of the hydraulic cylinder. The ascending, descending, forward and backward movement of the moving beam is realized by a double-wheel inclined track stepping mechanism, such as image 3 Shown. The walking beam system consists of several sets of double-wheel ramp type stepping mechanisms, which are composed of a lifting ramp seat 10, a lifting frame 6, and double rollers 7. T...

The invention relates to a walking beam system simulator of a steel billet heating furnace. The walking beam system simulator comprises a mobile beam ascending process stimulator, a mobile beam descending process stimulator, a mobile beam forward travel process simulator and a mobile beam backward travel process stimulator, the circuits of above four process stimulators are same to each other, each of the four process stimulators comprise a resistor R1, one end of the resistor R1 is connected with a control signal for controlling a mobile beam to ascend, the other end of the resistor R1 is connected with the inverted input end of a first amplifier A1, and the output end of the first amplifier A1 is connected with the inverted input end of a third amplifier A3 through a resistor R5; and the output end of a tenth amplifier A10 outputs a walking beam ascending / descending / forward travel / backward travel displacement signal. The invention also discloses a stimulation method of the walking beam system simulator of the steel billet heating furnace. The walking beam system stimulator and the simulation method thereof create conditions for walking beam control method research, control device development and the debugging before control device installation, substantially shorten the onsite debugging time of the walking beam, and greatly reduce the engineering enforcement cost.
Description
Technical field [0001] The invention relates to the technical field of walking beam type billet heating furnace control, in particular to a walking beam system simulator of a billet heating furnace and a simulation method thereof. Background technique [0002] Steel is the food of the industry, and the billet heating furnace is an important equipment in the production of steel. The walking beam is the core component of the walking billet heating furnace. It is composed of a fixed beam and a moving beam. Among them, the moving beam moves upward, forward, downward, and backward to move the billet forward step by step during the heating process in the furnace. transport. The moving speed of the moving beam must not only ensure the rhythm of production, but also ensure that the steel billet is lightly supported to avoid damage to the moving beam and the fixed beam due to collisions. Therefore, the moving beam must be controlled to accurately follow the set speed curve. [0003] The ...
