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

Embodiments of the present application provide a quick-change connector for a tundish, a method for using the same, and a process for changing the tundish and starting the pouring process, which relate to the field of continuous casting production technology. The quick-change connector of the tundish is a frame structure, and the material of the frame structure is steel refrigerant, which includes a connected frame upper part and a frame lower part, and the frame upper part and the frame lower part are connected by an intermediate hoop. At least opposite sides of the middle hoop have support portions extending outward in the transverse direction, the support portions are used to support the shell in the crystallizer. The method for using the tundish quick-change connector includes: placing the tundish quick-change connector in the crystallizer, and making the support part support on the blank shell formed in the crystallizer, and the upper part of the frame is exposed above the blank shell. It can ensure that the quick-change connector of the tundish is inserted into the crystallizer to a sufficient depth, ensures that the new molten steel can be fully solidified, and improves the success rate of quick change.

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...
