Problems solved by technology

[0005] From the above analysis, it can be seen that this compensation method can eliminate the cumulative error well only when the error between the actual displacement value and the process value is small, and with the increase of the step distance, the error between the set value of the next step distance and the process value The amount will gradually accumulate to a large amount, and because the walking beam is controlled by a large inertia (large inertia refers to the large load when the walking beam supports the steel, because the load is large, the inertia when the walking beam stops is large), once the actual displacement If the error between the value and the process value is too large, the step distance will be confused, and the billet in the furnace will be unevenly distributed, which will affect the accuracy of the billet on the roller table and the temperature of the furnace.

Embodiment Construction

[0020] see Figure 1 to Figure 4 , a walking beam control method for a regenerative walking heating furnace, comprising the following steps:

[0021] 1) Set the standard step distance D and the allowable maximum error value △Dmax of the walking beam in the walking beam control system of the heating furnace, and subtract the standard step distance D from the allowable maximum error value △Dmax to obtain the initial translational step distance of the walking beam The set value is D 0 . The centerline distance of the charging and discharging of the heating furnace in the practical application of the present invention is 16500mm. The standard step distance D of the walking beam is 250 mm, and the maximum allowable error value ΔDmax is 8 mm.

[0022] 2) Put the steel billet on the fixed beam, start the walking beam, and detect the translation distance of the walking beam through the translation sensor at the same time. Then follow the initial translation step set value D 0 Tra...

Abstract

The invention discloses a walking beam control method for a regenerative walking heating furnace. The invention relates to the field of walking beam control for a regenerative walking heating furnace. The distance is basically constant, the steel billet in the furnace is uniformly distributed and heated, and the steel billet can accurately walk on the roller table of the furnace.

Description

technical field [0001] The invention relates to the field of walking beam control for a regenerative walking heating furnace, in particular to a walking beam control method for a regenerative walking heating furnace. Background technique [0002] The regenerative walking heating furnace is used in the rolling mill. The main equipment of the regenerative walking heating furnace is the stepping mechanism, which is mainly composed of a fixed beam, a walking beam, a lifting cylinder, a translation cylinder and a driving mechanism. Composition of hydraulic system. The rise and fall of the walking beam are driven by the lifting cylinder along the slope of the lifting guide plate, and the forward and backward are driven by the translation cylinder. The walking heating furnace completes the heating of the billet through the cyclic actions of the walking beam's ascent (supporting the billet from the fixed beam), advancing (the billet moves forward), descending (the billet falls on t...
