Abstract

The invention discloses an ingot guiding method of a continuous casting machine. In the ingot guiding method of the continuous casting machine, the structure of an ingot guiding rod is optimized, andmeanwhile, the working mode of a withdrawal and straightening unit is improved, so that the walking stability of the ingot guiding rod in ingot guidance is improved, and the fluctuation of molten steel is reduced. The invention further provides a set of chain type ingot guiding rod of the continuous casting machine and a set of continuous casting machine system; in the chain type ingot guiding rodof the continuous casting machine, the ingot guiding rod is lengthened, and meanwhile, a spring plate is additionally provided, so that the walking stability in ingot guidance can be improved; the continuous casting machine system uses the chain type ingot guiding rod of the continuous casting machine; and the ingot production quality is improved. Through lengthening of the designed length of theingot guiding rod, each withdrawal and straightening unit synchronously applies pressure to the ingot guiding rod, so that the interference on walking of the ingot guiding rod during pressing of a pressing roller on the withdrawal and straightening unit in the ingot guiding process is reduced; and the process settings are changed, and the hot blank pressure is converted beforehand, so that the stress condition of the ingot guiding rod is improved, and the operation stability is improved.

Description

technical field [0001] The present invention relates to the technical field of casting systems, and more specifically relates to a continuous casting machine dummy method, a continuous casting machine chain dummy bar and a continuous casting machine system. Background technique [0002] The dummy bar is one of the important devices for continuous casting and steelmaking, which plays a key role in pulling the molten steel from the crystallizer to the tension leveler. [0003] At present, there are two types of dummy bars: chain dummy bars and rigid dummy bars. Due to the large length and size of the rigid dummy bar, there are many inconveniences in use and storage, so it is gradually eliminated. The chain dummy bar is widely used in various continuous casting machines due to its structural characteristics. The chain-type dummy bar is composed of dozens of chain links. Because of its simple structure, small storage space, low investment cost, and fast construction period, it...
