Description

Technical Field

[0001] The utility model relates to a wireless control device, in particular to a wireless control device for centering a dummy bar of a continuous casting machine. Background Art

[0002] In the continuous casting workshop, the dummy rod needs to be sent into the crystallizer before the continuous casting machine starts pouring, and then the dummy rod guides the initially formed billet in the crystallizer to move downward when pouring starts. If the dummy rod is not aligned with the center line of the casting strand when it is sent into the crystallizer before pouring starts, the dummy head may hit the lower mouth of the crystallizer, which may damage the equipment and increase the pouring preparation time, affecting the operation rate of the continuous casting machine; in addition, even if the dummy rod can enter the crystallizer in a non-centered state, it will guide the billet to deviate when pouring starts, which may result in the billet deviating seriously in the roller area and falling off the roller, or the side of the billet will always rub against other equipment, affecting the surface quality of the billet.

[0003] The smooth centering of the dummy rod is very important for the normal production of the continuous casting machine. In the current production, the centering action includes the rise and fall of the storage car, the forward and backward movement of the storage roller, and the forward and backward movement of the centering cylinder. Through the above actions, the position of the dummy rod on the storage car is adjusted to be centered with the crystallizer entrance. The whole centering process requires the cooperation of two people, one of whom checks the situation on site and directs the other person to control the equipment in the operating room through the intercom. During the work, it was found that since the operating room could not directly see the on-site situation, this centering method was not only inefficient, but also easy to cause inaccurate centering position. In addition, if the command is not clear or deviation occurs, it may also cause damage to equipment and personnel safety issues. Utility Model Content

[0004] In order to solve the above deficiencies in the prior art, the utility model aims to provide a wireless control device for centering the dummy bar of a continuous casting machine, so that one person can complete the dummy bar alignment of the prior art.
