Problems solved by technology

[0003] In the process of quick change of the tundish, the quick change connector of the tundish is used to connect the old and new molten steel. In the prior art, the quick change connector of the tundish is usually hoisted to the target position to insert the connector Molten steel in the mold, but this method is prone to large errors, so that the depth of the connecting piece inserted into the molten steel in the mold is not enough

Abstract

The embodiment of the invention provides a tundish quick-change connecting piece, a using method thereof and a pouring stopping, tundish changing and pouring starting process, and relates to the fieldof continuous casting production processes. The tundish quick-change connecting piece is of a frame structure, wherein the frame structure is made of a steel cooling material and comprises a frame upper part and a frame lower part which are connected, and the frame upper part and the frame lower part are connected through a middle hoop. At least two opposite sides of the middle hoop are providedwith supporting parts extending outwards in the transverse direction, and the supporting parts are used for supporting a blank shell in a crystallizer. The using method of the tundish quick-change connecting piece comprises the steps that the tundish quick-change connecting piece is arranged in the crystallizer, the supporting parts are supported on the blank shell formed in the crystallizer, andthe frame upper part is exposed above the blank shell. The tundish quick-change connecting piece is inserted into the crystallizer by enough depth, new molten steel can be fully solidified, and the quick-change success rate is increased.

Description

technical field [0001] The application relates to the field of continuous casting production technology, in particular, to a quick-change connector for a tundish, a method for using it, and a process for changing the tundish and starting the casting process. Background technique [0002] Tundish quick change means that during the continuous casting pouring process, when the working time of the tundish meets the requirements of the technical regulations, or when other steel pouring conditions change, the tundish pouring is interrupted in a short time, a new tundish is quickly replaced, and then casting continues. [0003] In the process of quick change of the tundish, the quick change connector of the tundish is used to connect the old and new molten steel. In the prior art, the quick change connector of the tundish is usually hoisted to the target position to insert the connector The molten steel of the mold, but this method is prone to large errors, so that the depth of the...
