Description
Technical Field
The invention belongs to the field of continuous casting in the metallurgical industry, and particularly relates to a narrow-side taper control method for an electric width adjusting device of a crystallizer.
Background
The crystallizer, the most critical equipment in a continuous casting machine, is a metallurgical reactor which cools molten steel to a fixed size and has a certain billet shell thickness. The width adjusting device is used for adjusting the width and the taper of narrow edges at two sides of the crystallizer, and is used for meeting the requirement of switching different slab width specifications in the continuous casting process of a continuous casting machine. The method is realized by moving an upper screw rod and a lower screw rod 3 of narrow edges at two sides of a crystallizer. As shown in the following figure 1, the transmission device uses four sets of alternating current servo motors and speed reducers 2 to respectively push a screw rod 3, so that two narrow sides of the crystallizer move to change the width and the taper of the crystallizer.
The cross-sectional size of the mold is determined according to the nominal cross-sectional size of the cold cast slab and considering the shrinkage of the cast slab during solidification. In order to reduce the gap between the narrow-side blank shell and the narrow-side copper plate 4 of the crystallizer, improve the heat-conducting property of the copper plate 4 of the crystallizer to accelerate the growth of the blank shell and to make the wide and narrow sides of the crystallizer cool uniformly, the design of the crystallizer needs to adopt a taper, i.e. the section of the lower opening is slightly smaller than that of the upper opening, as shown in fig. 1.
The taper control in the width adjusting process of the crystallizer is to calculate the taper of the narrow side according to the encoder data on the motor 1 and the proportional relation of the similar triangle. After the crystallizer is subjected to thermal state width adjustment for many times, the taper measured by the encoder of the motor 1 deviates from the actual taper due to the existence of equipment gaps at the connection positions of the worm gear speed reducer and the pin shaft in the mechanical transmission mechanism. After each pouring, the measured taper has deviation, and when the deviation is serious, an accident will occur to cause steel leakage.
