Problems solved by technology

The cost of integral brick-laying ladles is too high; while integral pouring ladles are not resistant to erosion during the refining process, especially the contact area between the upper slag line and the ladle is eroded too quickly, the service life is low, and it is easy to cause ladle shifting accidents. Great security risk

Embodiment Construction

[0036] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples and accompanying drawings. This embodiment is only used to explain the present invention, and does not constitute a limitation to the protection scope of the present invention.

[0037] Such as figure 1 An embodiment of the ladle composite masonry method and the composite masonry ladle is shown.

[0038] A ladle composite masonry method, comprising the steps of:

[0039] Step 1. Clean the ladle, place the nozzle seat brick and the breathable brick;

[0040] Step 2. Cast the spinel castable, vibrate and degas, level it to the height of the bottom of the ladle, and dry it naturally for 72 hours;

[0041] Step 3, put in the tire, and wrap a layer of plastic film on the tire;

[0042] Step 4. The spinel castable is poured to the height of the masonry slag line brick, and dried naturally for 72 hours;

[0043] Step 5...

Abstract

The invention discloses a steel ladle composite building method and a compositely-built steel ladle. The compositely-built steel ladle comprises a work layer and a top sealing material; the inner side wall and the outer side wall of the work layer and the inner side wall and the outer side wall of the top sealing material are unfolded to be in an annular fan shape; the diameter of the upper end of the top sealing material is larger than the diameter of the upper end of the work layer; annular-fan-shaped slag line bricks are connected to the inner side of the upper end of the work layer; an annular-fan-shaped packing layer is connected to the outer side of the upper end of the work layer; the slag line bricks are flush with the upper end of the packing layer; and the top sealing material is connected to the upper ends of the slag line bricks and the upper end of the packing layer. Steel ladle building is conducted through a slag line magnesia carbon brick and alumina-magnesia spinel castable composite technology, the steel ladle has the advantages of both long service life and low cost, and the requirements for the safety and economical efficiency in the steel ladle refining process are met.

Description

technical field [0001] The invention relates to a matching equipment for a refining furnace and a manufacturing method thereof, and is especially suitable for a molten steel receiving container and a manufacturing method thereof, specifically a ladle composite masonry method and a composite masonry ladle. Background technique [0002] With the extensive use of LF furnace refining methods, the safety and cost of ladles have become the primary concerns. The cost of integral brick-laying ladles is too high; while integral pouring ladles are not resistant to erosion during the refining process, especially the contact area between the upper slag line and the ladle is eroded too quickly, the service life is low, and it is easy to cause ladle shifting accidents. Great security risk. [0003] In order to solve the problems of high cost and low service life of ladles for LF refining, and give full play to the advantages of both brick-laying ladles and integral casting ladles, the co...
