Description
Technical field
The invention belongs to smelting molten steel running gate system equipment, particularly a kind of slide gate nozzle formula steel ladle by stuffing sand drainage molten steel, opens in the process of watering in cast, carries out stuffing sand separation and recovery, obtains the sliding nozzle device of purifying of steel.
Background technology
At present, in continuous-cast blank and die casting production line production process, due to the cast of slide gate nozzle formula steel ladle open water time, unsintered stuffing sand flows into cast passage, pollutes molten steel, have impact on the cleanliness factor of molten steel.The stuffing sand flowed into, can produce nonmetal inclusion at interiors of products and surface, the quality problems such as local reaction point composition is inconsistent, have had a strong impact on quality requirement and the serviceability of product.And stuffing sand once uses, cause and produce waste.
Summary of the invention
The object of the invention is to unwrap Problems existing in the process of watering for above slide gate nozzle formula molten steel and a kind of structure of designing is simple, easy to operate, and by stuffing sand separation and recovery, a kind of sliding nozzle device of purifying of steel can be obtained.
For achieving the above object, the present invention by the following technical programs:
Improved a sliding nozzle device for Cleanliness of Molten Steel by separation and recovery stuffing sand, comprise refractory brick seat, be arranged with filling pipe end in refractory brick seat, filling pipe end lower end is provided with the upper slide be fixed on bottom brick seat, and upper slide is provided with the steel outlet hole corresponding with filling pipe end; Upper slide lower slide is provided with lower skateboard, described lower skateboard communicates with steel outlet hole and is provided with two through holes: quicksand hole and steel outlet hole, distance between holes is greater than the steel outlet hole of upper slide, to having recycling can below quicksand hole, in recycling can and quicksand hole is built with stuffing sand, be the remaining space of recycling can stuffing sand except stuffing sand in recycling can, recycling can is identical with the stuffing sand amount joining ladle with the remaining space of stuffing sand; The lower end of steel outlet hole is fixed with the corresponding lower mouth of a river.
Further, upper slide is provided with choked flow side plate.
Further, asbestos board is provided with bottom described recycling can; The neck of tank is drilled with some tiny steam vents.
Operation principle of the present invention and beneficial effect show:
Lower skateboard lengthens, and increases a quicksand hole, becomes diplopore from single hole; A recycling can is filled, for reclaiming stuffing sand below quicksand hole.Filling pipe end and upper slide are fixed on by mechanism member and wrap the end; Lower skateboard and the lower mouth of a river are the mouth of a river under the disjunctor of integral type,
Be fixed on together in slip planker.
Recycling can is the heat-resisting steel structural member with snap joint, connects fast with slip planker.The neck of tank is drilled with some tiny steam vents, tank inner bottom part places one block of soft asbestos board, play the effect of getting tank compensator or trimmer pressure, the steel flow port that recycling can capacity should meet filling pipe end and upper slide causes internal orifice dimension to become large and maximum stuffing sand addition before scrapping due to washing away and corroding of molten steel.
The determination of yield: untapped lower skateboard quicksand hole is placed on recycling can, preheated stuffing sand is filled it up with recycling can and quicksand hole (also can control the height added as required) from quicksand hole, this total amount is yield.Before tapping, then the stuffing sand in yield is added in ladle, remainingly stay in tank, load onto recycling can.Open when watering, under disjunctor, the mouth of a river is under the dragging of slip planker, and make lower skateboard quicksand hole and upper slide steel outlet hole UNICOM, unsintered stuffing sand flows into recycling can rapidly; Instantaneous, under slip planker drags disjunctor, the mouth of a river is to lower skateboard steel outlet hole and upper slide steel outlet hole UNICOM, and automatic casting obtains clean molten steel.
