Description

Steel ladle edge prefabricated section and steel ladle edge structure
Technical field
The utility model is related to steelmaking equipment technical fields, and in particular to a kind of steel ladle edge prefabricated section and steel ladle edge knot Structure.
Background technology
Steel-making ladle substantially mostly adds metal platen to carry out closed side using packet along brick cooperation castable refractory at present Method, or add metal platen to carry out closed method using castable refractory, both building methods have used castable refractory And metal platen, effect are exactly to compress lower part slag line magnesia carbon brick.
All there are the disadvantages such as the castable porosity is high, intensity is low in above two mode, and connect with ladle shell it is insecure, this Sample can cause steel ladle edge slagging serious, to cause large area mechanical failure in scarfing cinder, or even damage, cause it is unplanned under Line not only influences to make steel whole rhythm, but also increases the amount of labour, time-intensive, expensive.
The damage of steel ladle edge can substantially be summarized as at 2 points:Material selection is improper to be caused easily to ooze slag, dry slag, slagging, is made At the Focal drug-block of scarfing cinder;Structure design is unreasonable to cause closure undesirable, and high temperature resistance is poor, and high temperature is caused to damage.
It is well known that ladle during access molten steel, refining, scarfing cinder can the long-term very high molten steel of Contact Temperature, this Sample metal platen can be burnt out by molten steel, and the service life is relatively low, not have the effect compressed for a long time;Castable is due to its specific construction party Formula leads to that its porosity is higher, intensity is relatively low, and slag infiltrates can penetrate into inside stomata for a long time during ladle use, slag Volume change necessarily leads to the structure change of castable refractory during multiple hot and cold alternation, since such castable thermally expands Much smaller than the volume expansion of slag, in addition castable structural strength is low, it will ultimately result in castable and peel off and disintegrate;Slag penetrates into resistance to It in the stomata of fiery castable, easily causes packet along surface slagging, is generally cleared up by the way of hook slag, will often wrap in this way along hook It is bad to cause mechanical damage, cause ladle to shift to an earlier date offline repair, not only affects the turnover rhythm of ladle, but also cause to ladle liner brick Damage, increases maintenance cost;Since castable will add water in construction, so building the ladle of completion by laying bricks or stones before being taken into use The baking by small fire, moderate heat to big fire is had to, not only reduced the turnover rhythm of ladle in this way but also increases the input of ladle; In addition, traditional steel ladle edge must be removed when replacing slag line magnesia carbon brick, slag line magnesia carbon brick builds steel ladle edge by laying bricks or stones again after the completion of building by laying bricks or stones, Not only increase material and cost of labor in this way, but also increases the turn around time of ladle.
Utility model content
It is not easily to fall off that the purpose of this utility model is to provide castables, and cleaning is not easily damaged when repairing, and reduces production Period and production it is raw this, steel ladle edge prefabricated section with long service life, packet are along structure and building method, to solve above-mentioned background skill Traditional ladle service life is short in art, cleaning maintenance cycle length, easily damaged, of high cost, the low technical problem of efficiency.
