Abstract
Provided is an accessory type integrally-poured permanent lining structure for the wall of a steel ladle. A heat insulation layer is arranged on the side wall of the inner wall of the steel ladle. The accessory type integrally-poured permanent lining structure is characterized in that a weld crater integrally-poured permanent layer is poured on the portion, below a slag line, of the heat insulation layer on the side wall of the inner wall of the steel ladle and is a high-alumina castable layer, an integrally-poured permanent layer is poured on the portion, above a slag line, of the heat insulation layer on the side wall and is a magnesium and chrome castable layer, a weld crater work layer is poured on the surface of the weld crater integrally-poured permanent layer, and a slag line work layer is constructed on the surface of the integrally-poured permanent layer on the portion, above the slag line, of the heat insulation layer on the side wall. According to the accessory type integrally-poured permanent lining structure, an original integral common high-alumina integrally-poured permanent layer arranged on the portion, above and below the slag line, of the inner side wall of the steel ladle is improved and different refractories are adopted above and below the slag line, namely, the weld crater integrally-poured permanent layer below the slag line is the high-alumina castable layer, and the integrally-poured permanent layer above the slag line is the magnesium and chrome castable layer. Through the improvement, the breakout accidents of the slag line of the steel ladle are reduced.
Description
Technical field
The utility model belongs to the refractory material application, particularly a kind of material formula steel ladle permanent liner structure of joining.
Background technology
The converter ladle comprises electric furnace ladle wall monolithic castable casting and constructing, what adopt is common high alumina permanent layer monolithic castable, as shown in Figure 1, ladle 100 inwall sidewalls are cast with heat-insulation layer 10, the integrated poured permanent layer 20 of common high alumina, and integrated poured permanent layer 20 surfaces of the sidewall that described slag line is upper and lower are slag line working lining 30, molten pool working layer 40 respectively.
After integrated poured, common high alumina permanent layer castable globality and can meet instructions for use service life under safety condition, but high alumina permanent layer castable limits because of material property own, not anti-slag and molten steel corrode, in the ladle operation process, the slag line brick is weakest link, when often occurring that slag line brick melting loss is too fast or abnormal service life occurring, the direct leakage of slag lining permanent layer, bring very large potential safety hazard to scene.
Summary of the invention
The purpose of this utility model is to provide a kind of integrated poured steel ladle permanent liner of material formula structure of joining, can improve ladle running security performance, make ladle slag line occur that melting loss is too fast or occur when abnormal, the high alumina castable used at present can't be kept out the erosion of molten steel, and magnesium chromium permanent layer castable can be kept out 1～2 slag line molten steel impact, can guarantee like this safe operation of ladle.
For achieving the above object, the technical solution of the utility model is:
A kind of integrated poured steel ladle permanent liner of material formula structure of joining, establish heat-insulation layer on the ladle inner wall sidewall; It is characterized in that, the following ladle inner wall sidewall heat-insulation layer upper of corresponding slag line has the integrated poured permanent layer in molten bath, and it is the high alumina castable layer; The above sidewall heat-insulation layer upper of slag line has integrated poured permanent layer, and it is the magnesium chromium matter cast bed of material; Described molten bath also is cast with molten pool working layer on integrated poured permanent layer surface; Also built the slag line working lining by laying bricks or stones on integrated poured permanent layer surface on sidewall heat-insulation layer more than described slag line.
The beneficial effects of the utility model:
The utility model adopts respectively different anti-materials for the whole integrated poured permanent layer of common high alumina is improved to slag line up and down up and down by original ladle inner wall sidewall slag line, and the following integrated poured permanent layer in molten bath of corresponding slag line is the high alumina castable layer; The above integrated poured permanent layer of slag line is the magnesium chromium matter cast bed of material; Having reduced ladle slag line bleed-out accident by above-mentioned improvement occurs.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing ladle wall.
The structural representation that Fig. 2 is the utility model embodiment.
The specific embodiment
Referring to Fig. 2, a kind of integrated poured steel ladle permanent liner of material formula structure of joining of the present utility model, establish heat-insulation layer 1 on the ladle inner wall sidewall; Following ladle inner wall sidewall heat-insulation layer 1 upper of corresponding slag line has the integrated poured permanent layer 2 in molten bath, and it is the high alumina castable layer; Above sidewall heat-insulation layer 1 upper of slag line has integrated poured permanent layer 3, and it is the magnesium chromium matter cast bed of material; Described molten bath also is cast with molten pool working layer 4 on integrated poured permanent layer 2 surfaces; Also built slag line working lining 5 by laying bricks or stones on integrated poured permanent layer 3 surfaces on sidewall heat-insulation layer 1 more than described slag line.
After the utility model embodiment, the ladle slag line position occurs that leakage steel situation reduces greatly, eliminates the leakage of slag lining ladle substantially.Ladle running security performance improves greatly, on the bag wall permanent layer that this kind of method also may extend into the converter ladle is integrated poured.
