Description
Technical field
The utility model belongs to converter taphole refractory part field, relates in particular to a kind of coverter pig magnesia-alumina-carbon brick.
Background technology
The converter taphole life-span is one of important technical indicator of converter steelmaking.Due to the direct erosion and the violent scour that frequently stand high-temperature molten steel and hyperoxia voltinism slag, the effect of rapid heat cycle causes tap hole very easily to destroy in addition.The length in its life-span directly has influence on converter smelting cycle, STEELMAKING PRODUCTION rate and pushing off the slag effect, and then affects steel quality.
At present, the structure of converter taphole is nearly all to be formed by segmentation brick cup, filler, sectional pipe brick masonry both at home and abroad, particularly the converter tapping port part is laid bricks, often suffer washing away of high temperature melting steel, life-span is very short generally at 40～60 heats, therefore need to during stove labour, repeatedly repair even and change, making it cost increases.In addition, converter taphole adopts the technological line of segmentation brick cup, filler and sectional pipe brick to exist complicated operation, and inefficiency, to the certain restriction of production cycle existence of converter.
The utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, stable, and long service life is easy for installation, the coverter pig magnesia-alumina-carbon brick of high efficiency.
For solving the problems of the technologies described above, the utility model is to realize like this.
The coverter pig magnesia-alumina-carbon brick, it comprises whole magnalium carbon pipe brick and whole magnalium carbon brick cup; The inner chamber of described whole magnalium carbon pipe brick and whole magnalium carbon brick cup is cylindrical hole; The lower surface of described whole magnalium carbon pipe brick is provided with annular notch; Corresponding annular notch position, the upper surface of described whole magnalium carbon brick cup is provided with annular projection; Described whole magnalium carbon brick cup is through the fixedly clamping of annular notch of annular projection and whole magnalium carbon pipe brick.
As a kind of preferred version, the utility model is provided with fitting recess on described whole magnalium carbon brick cup.
The utility model is simple in structure, high efficiency.The utility model is the design of docking with whole carbon-free brick cup port by the whole carbon-free pipe brick port of employing, its installation process is convenient, reduced the frequency and labour intensity that tap hole refractory brick is repaired, alleviated the erosion of molten steel high temperature oxidation and mechanical erosion and destroyed, obviously extend work-ing life.In addition, the utility model adopts the annular notch fixedly clamping design of whole magnalium carbon brick cup through annular projection and whole magnalium carbon pipe brick, makes protective refractory system monolithic stability.The utility model is provided with fitting recess on described whole magnalium carbon brick cup, and this obviously improves the transport efficacy of converter refractory brick.
