Accident swing groove device

Abstract

The invention comprises an accident swing groove device, comprising a straight punched groove and one or more groups of flow guide grooves, wherein the straight punched groove comprises an adapting part internally arranged on the bottom of the groove body of the straight punched groove, and a backflow part; the backflow part is a cube comprising an upper plane which is parallel to the plane of the bottom of the groove body; the adapting part is a cube comprising an inclined plane which is inclined relative to the plane of the bottom of the groove body, connected with the top of the groove body of the straight punched groove via the straight line of the highest point of the inclined plane, and connected with the upper plane of the backflow part via the straight line of the lowest point of the inclined plane; and the flow guide groove is an integrated structure which is divided into two parts, namely, a first flow guide groove and a second flow guide groove. According to the invention, the spattering of molten steel can be reduced, and the safety factor of the use of the accident swing groove device can be increased; the overall structure is formed by connecting a plurality of sections, and simple and convenient in detachment and connection steps; and a spare flow guide groove can be replaced on line during production and use processes, without influence on the production progress.

Description

technical field [0001] The invention relates to an accident slot swinging device, which is especially suitable for the accident slot swinging device in the iron and steel smelting and continuous casting process. Background technique [0002] Continuous casting, that is, after the molten steel produced by the converter is refined in the refining furnace, the molten steel needs to be cast into billets of different types and specifications. The continuous casting process is to transport the ladle containing the refined molten steel to the rotary table. After the rotary table is rotated to the pouring position, the molten steel is poured into the tundish, and the tundish distributes the molten steel to each mold by the nozzle. The mold makes the casting Forming and rapidly solidifying the crystallization, the tension leveler and the crystallization vibration device work together to pull out the casting in the crystallizer, after cooling and electromagnetic stirring, it is cut in...

AI Technical Summary

Problems solved by technology

During the actual use of the accident swing device, molten steel directly hits the bottom of the swing tank, causing serious splashing of molten steel and affecting the safety of operators

The accident trough device is made by the integral casting method. If the internal refractory material is damaged during production and use, it is usually replaced completely, which causes waste of resources to a certain extent, and it is difficult to repair or replace online, posing safety hazards
