Abstract
The invention belongs to the technical field of refractory containers, and particularly relates to a tundish with destructively replaceable striking plates. The tundish with the destructively replaceable striking plates comprises a steel shell, a fiber felt layer, a permanent casting layer and a paint layer, wherein the fiber felt layer is arranged in the steel shell; the permanent casting layer is arranged in the fiber felt layer; the paint layer is arranged on the surface of the permanent casting layer; a plurality of invasive water openings and the striking plates are arranged in the tundish with the destructively replaceable striking plates; a protecting plate and a slag blocking wall are arranged above each striking plate, and are in opposite arrangement; each slag blocking wall is positioned between each striking plate and the corresponding invasive water opening; each striking plate comprises a seat body and a plate core arranged in the seat body. On the basis of the existing tundish, the striking plates are further improved; on one hand, the streamline structure of the striking plates is added; the service life is prolonged; a modular thought of the striking plates is also provided; the striking plates can realize the modular integral replacement. The replacement is convenient; the operation is convenient and fast; the production efficiency is improved.
Description
Technical field
The invention belongs to refractory container technical field and in particular to a kind of shock plate can damage type change tundish.
Background technology
Tundish is the refractory material containers used in mini-mill steelmaking, accepts first to pour, from ladle, the steel getting off
Water, is then assigned in each crystallizer by middle water containing opening again.Tundish is the intermediate link of STEELMAKING PRODUCTION flow process, and
It is the connecting points being turned to continuous operation by intermittently operated.Tundish is improve output of steel and quality important as metallurgical reaction
One ring.
With Tapping Temperature of Bof raising, when the application of various ladle refining techniques, and middle continuous cast crystallizer number are with even pouring
Between continuous improvement, the pressure that middle ladle-lining is subject to constantly increases, and working environment becomes more severe.Effect in view of middle bag
(decompression, current stabilization, go to be mingled with, store and shunt molten steel) is it is necessary to centering ladle-lining is optimized design, reasonable selection fire proofed wood
Material.
Middle bag refractory material typically by heat-insulation layer, permanent layer and working lining, impact zone and slag blocking wall position, mouth of a river flow control
System forms.In wrap face also have in clad, using integral ladle cover.In conjunction with steel mill production technology, features, will first at present
The tundish metallurgy achievement in research entered wraps face in being applied to, intend, using new design, new material and integrated masonry, reaching energy-conservation fall
Consumption, the purpose increased economic efficiency.
Existing tundish has following structure: 1) heat-insulation layer: thickness is the aluminosilicate property fiber felt of 20mm；2) permanent
Layer: side wall and bottom adopt the high alumina castable of bulk density >=2.45g/cm3；3) working lining: side wall and bottom adopt magnesium
Calcareous middle coating material；Containment wall slag lining thickness suitably thickeies 20mm.4) impact zone: using corundum shock plate；5) slag blocking wall
And backplate: using magnesia precoated plate
Existing tundish has a characteristic that 1) in bag permanent layer castable, its intensity is high, good integrity；2) new
Slag blocking wall prefabricated section, has shunting action evenly and slag corrosion resistance ability；3) in, bag corundum shock plate is set using new
Meter, more reasonable by steel face, and can prevent molten steel from splashing, production security is greatly improved；4) adopt magnalium point around pocket block
, it is easy to construct, resistance to slag corrosion is good for spar ramming mass；5) novel environment-friendly joint filler, can be tight by sealing between the mouth of a river and brick cup
Real and more environmentally friendly；6) clad in entirety, three pieces little original middle clads are integrated into an entirety, are more convenient to install, and use
Life-span is substantially improved.
Content of the invention
For solve the deficiencies in the prior art, the invention provides a kind of shock plate can damage type change tundish.
A kind of shock plate can the tundish changed of damage type, the fibre felt layer including box hat, being arranged in described box hat, set
Put in the permanent LIFT of described fiber felt in the layer and be arranged on the described dope layer forever pouring layer surface, described shock plate
Multiple invasive nozzles and shock plate can be provided with the tundish of damage type replacing, be respectively provided with above described shock plate
Backplate and slag blocking wall, described backplate and described slag blocking wall is had to be oppositely arranged, described slag blocking wall is located at described shock plate and described invades
Enter between the formula mouth of a river, described shock plate includes pedestal and the plate core being arranged in described pedestal.
Further, described plate core includes the matrix of cuboid and the impact body of semielliptical shape.
Further, described matrix and described impact body by integral forming.
Further, it is provided with thread groove in described matrix.
Further, it is provided with pocket block around described invasive nozzle.
Further, the upper surface of described pedestal is that domatic, domatic angle is 20 °～45 °.
The present invention, on the basis of existing tundish, has carried out further improvement to shock plate, on the one hand increased
The streamlined configuration of shock plate, increased service life, additionally provides the thinking that impact board modular is changed, can be to shock plate
Carry out the replacing of the modular of part.It is convenient to change, and simple operation improves production efficiency.
