Transition brick for joint part of slag line and wall of ladle

Abstract

The invention discloses a transition brick for a joint part of a slag line and a wall of a ladle. a, when a slag line brick consists of the following raw materials in part by weight: 69 to 86 parts of MgO and 13 to 18 parts of C, and a wall brick of the ladle consists of the following raw materials in part by weight: 50 to 74 parts of Al2O3, 5 to 20 parts of MgO and 0 to 12 parts of C, the transition brick consists of the following raw materials in part by weight: 30 to 40 parts of Al2O3, 30 to 45 parts of MgO and 13 to 15 parts of C; b, when the slag line brick consists of the following raw materials in part by weight: 69 to 86 parts of MgO and 13 to 18 parts of C, and the wall brick of the ladle consists of the following raw materials in part by weight: 60 to 65 parts of MgO and 0 to 10parts of C, the transition brick consists of the following raw materials in part by weight: 69 to 75 parts of MgO and 10 to 12 parts of C; and c, when the slag line brick consists of the following raw materials in part by weight: 69 to 75 parts of MgO and 14 to 18 parts of C, and the wall brick of the ladle consists of the following raw materials in part by weight: 60 to 68 parts of Al2O3 and 6 to 18 parts of MgO, the transition brick consists of the following raw materials in part by weight: 30 to 40 parts of Al2O3, 30 to 45 parts of MgO and 8 to 10 parts of C.

Description

technical field [0001] The invention relates to a steel ladle inner lining, in particular to a transition brick used for the ladle slag line and the ladle wall junction. Background technique [0002] The ladle is a special equipment used to receive and pour molten steel from the steelmaking furnace. Due to the large difference or incompatibility of the refractory bricks used in the slag line working layer of the ladle lining and the cladding wall working layer, the connection between the slag line working layer and the cladding wall working layer will be corroded in advance during use , which not only shortens the service life of the ladle, but also increases the work load of digging or subsidizing the ladle, and also increases the material consumption of a single ladle of the ladle. Contents of the invention [0003] The purpose of the present invention is to provide a transition brick with long service life for the junction of ladle slag line and cladding wall. [0004...
