Abstract
The invention relates to a continuous casting device for producing slabs made of steel, comprising a mold and a downstream strand guide having racks with lower and upper frames, on which guide rollers are provided, the jaw width of which can be continuously adjusted by means of the adjusting elements connecting the frames. Cylinders are provided as the adjusting elements, which are controlled by shift valves. To this end, the advantages of position-controlled cylinders as adjusting elements are to be used, however the costs are to be lower. The invention therefore provides that the valves are configured as quick-acting valves, or that the valves are equipped with a controller enabling a quick switching process.
Description
Technical field
The present invention relates to a kind of casting apparatus that is used to make the slab of steel, its have crystallizer and after the strand-guiding device that connects, described strand-guiding device has the support that comprises underframe and upper frame, on described upper frame and underframe, be provided with each deflector roll, their A/F can infinitely be regulated by the regulating element that said frame is connected, hydraulic cylinder wherein is set as regulating element, described hydraulic cylinder is controlled by switch valve (Schaltventile).
The invention still further relates to a kind of method that is used to operate described casting apparatus in addition.
Background technology
By the known a kind of casting apparatus that is used to make the slab of steel of EP 980 295 B1, its have crystallizer and after the strand-guiding device that connects, described strand-guiding device has the support that comprises underframe and upper frame, be provided with each deflector roll on described upper frame and underframe, their A/F can infinitely be regulated by the regulating element that connects said frame.Be provided with detector for displacement measuring and pressure sensor at this, they survey the adjusting power of regulating element, and can obtain the A/F of deflector roll by them.Be provided with vibrator in addition, regulating element can be excited into vibration with this vibrator.In practice, be referred to as the CyberLink fan-shaped section in this employed fan-shaped section.Generally, vibration is described by the preset value of many discontinuous datum marks of each vibration period, and datum mark has sine-shaped distribution, and is forced to move so that adjusting position.
The information relevant with process that adopts this device to obtain determining is as the position of liquid core end.
At the regulon of this employed adjusting position than expensive, thereby people propose, and replace above-mentioned regulon by the cylinder by switch valve control.This scheme is cheap, yet shortcoming is also arranged, and promptly favourable vibrator no longer can be realized in known manner.
Summary of the invention
So the objective of the invention is to, constitute the casting apparatus of the described type of beginning like this, make therefore can make full use of the advantage of the cylinder of adjusting position that cost is less but then as regulating element.
This purpose realizes by following measure according to the present invention, that is: valve is designed to acceleration switching valve or valve has the control device that can realize fast handover procedures.
According to another structure, valve should have and is used for the interface of setting pressure sensor alternatively.
Propose in addition:
By switch valve fast back and forth switch in short measuring intervals of TIME (times in several seconds), make upper frame place oscillating movement so that can analyze displacement signal and force signal in known manner subsequently.No longer consider sinusoidal motion as known up to now at this, but consider because fuzzy (verschliffene) triangular motion of the inertia of system.This precision and not influence of reliability to analyzing.
2. valve has the interface that is used for the setting pressure measurement mechanism, thus device for pressure measurement or provide from the beginning or valve can easily install additional under the situation of " upgrading ".
Research to the measuring transducer on existing CyberLink fan-shaped section with switch valve technology shows, under the situation of using the nozzle bigger than general (1.8-2.0mm rather than 1.3-1.5mm) commonly used, accessible deformation velocity be arranged on the continuous casting billet hull shape shape pace of change of nature according to the croop property of material cast and be in at the identical order of magnitude of original C yberLink fan-shaped section, make it possible to analyze.
Has not been conclusive in the not necessarily sine-shaped situation of motion that forms under the situation of control when considering analytical method (hysteresis, phase transition process, the motion of liquid pool face).
Cylinder position in the middle of during measuring does not keep constant situation to take in by short as far as possible Measuring Time in case of necessity.
Can transship monitoring by working pressure measuring transducer optionally.
Even applying pressure measuring transducer not, replace lagging behind when the casting horizontal signal is associated with the upper frame vibration-or during phase shift analysis, the ways and means that is proposed is also pointed out a kind of mode that is used for enforcement " CyberLink-miscellaneous function ".
(electronics) device that additionally is used for the acceleration switch process can be favourable.
In addition, it also can be favourable the air blast be used for improving heat loss through convection being installed in the valve zone.
