Problems solved by technology

The former method is too single. Due to the complex situation in the crystallizer, various factors often have cross-effects. A single study of a certain factor has little guiding significance for on-site production.
The test casting machine simulates the production experiment method. T

Abstract

A steel liquid solidification simulator in a continuous casting crystallizer comprises a machine seat, a steel furnace, a crystallizer, a throwing motor, a vibration motor, a cooling water channel and a data acquisition system. Two lead screws are arranged on the machine seat, one ends of the lead screws are perpendicular to the plane of the machine seat, and the other ends of the lead screws areconnected with a motor driving device. A lifting bracket is arranged on the lead screws. The steel furnace is arranged on the machine seat. Both the throwing motor and the vibration motor are arranged on the lifting bracket, the crystallizer is driven by the vibration motor to vertically vibrate, the throwing motor drives a throwing board, and the throwing board is located below the crystallizer.By simulating practical production process of continuous casting, the steel liquid solidification simulator in the continuous casting crystallizer measures heat flux change curves at meniscus positions in the crystallizer under different continuous casting process parameters, obtains a steel liquid solidification shell with characteristics of practical casting blank, and achieves research on initial solidification performance of steel liquid in the crystallizer and influence of the continuous casting process parameters on steel liquid initial solidification performance, and is convenient to operate, low in test cost and suitable for serving as a device for laboratory to research various process conditions of the continuous casting crystallizer.

Description

technical field [0001] The invention discloses a solidification simulation device for molten steel in a continuous casting crystallizer, which belongs to the technical field of continuous casting of iron and steel. Background technique [0002] The mold is the place where molten steel initially solidifies. Various quality defects of the slab, such as deep vibration marks, wrinkles, transverse cracks, etc., and even breakouts, originate at the meniscus of the mold. However, there are many factors affecting the initial solidification behavior of molten steel at the meniscus, and they interfere with each other. It is almost impossible to independently study the influence of a single factor on the initial solidification behavior. Continuous casting vibration marks are very common and difficult to overcome technical problems in modern steel continuous casting production. Slab vibration marks usually cause surface cracks, and serious steel breakout accidents occur. At the same tim...
