Embodiment 1

[0025] The technical scheme adopted by the present invention is, according to the installation position and size of the tundish slag retaining wall 7, two inserts 1 are made of heat-resistant cast steel, and they are symmetrically welded on the side of the dry material working lining construction film 2, when When the dry material working lining construction film 2 constructs the tundish working lining 3, the inlay piece 1 welded on the dry material working lining construction film 2 will form a two-fold structure at the position where the tundish working lining 3 is installed with the slag retaining wall 7. two grooves, and the two sides of the tundish slag retaining wall 7 are embedded in the two grooves.

[0026] The present invention provides a continuous casting tundish slag retaining wall insert 1, which is characterized in that the cross section of the insert 1 is trapezoidal, and L is the length of the insert 1, that is, the length H of the tundish slag retaining wall 7...

Embodiment 2

[0036] Others are the same as embodiment 1, the difference is:

[0037] The length L of the mosaic 1 is 950 mm, the width m is 160 mm, the thickness n is 40 mm, and the inclination a is 80°.

Abstract

The invention relates to slag wall inserts of a continuous casting tundish and an embedded installing method thereof. The slag wall inserts of the continuous casting tundish are mainly characterized in that heat-resisting cast steel is used to produce two inserts according to the installing position and size of the slag wall of the tundish; the two inserts are symmetrically welded on the side surface of a dry material working lining construction membrane; when the dry material working lining construction membrane constructs a tundish working lining, the inserts welded on the dry material working lining construction membrane form two grooves at the positions on the tundish working lining for installing the slag wall, and the two side edges of the tundish slag wall are embedded into the twogrooves. The slag wall inserts and the embedded installing method disclosed by the invention are adopted for installing the tundish slag wall, the method is simple, the tundish slag wall is positioned accurately, the technical problem of easy collapsing of a long-service-life tundish slag wall is solved fundamentally, production accidents and quality accidents are avoided, and the service lives of the continuous casting tundish and the slag wall are prolonged.

Description

technical field [0001] The invention relates to a continuous casting tundish slag retaining wall insert and an embedded installation method thereof, belonging to the technical field of iron and steel metallurgy continuous casting tundish flow field optimization. Background technique [0002] At home and abroad, in order to improve the molten steel flow field in the continuous casting tundish, prolong the residence time of molten steel in the tundish, and promote the floating and discharge of inclusions, a flow control device is installed in the continuous casting tundish, generally by the upper slag stop The wall and the slag retaining dam at the lower part are used in combination to achieve better flow control effect. At present, with the large-scale and high-efficiency of continuous casting machines, the dry-type vibrating material working lining of continuous casting tundish has been rapidly popularized and applied. There are defects or deficiencies in the installation m...
