Abstract
The utility model provides an air brick core for ladle, including air brick A, the bell mouth has been seted up on air brick A, and be provided with air brick B in the bell mouth, air brick B stretches into that the interval sets up the formation air chamber between one end and the air brick A in the air brick A, it forms the flame retardant coating to scribble the fire clay on air brick B's the conical surface, the fire -resistant mud layer outside is gone up the cover and is equipped with the steel bushing that surrounds the air brick B conical surface, air brick B keeps away from one of air chamber and serves and install metal attachment, metal attachment fixes on the steel bushing, and be connected with the tail pipe on the metal attachment. The utility model discloses air brick core skin does not use steel bushing and fire clay, can strengthen the security of air brick, and can reduce its manufacturing cost.
Description
Technical field
This utility model relates to fire resisting material field, especially relates to a kind of ladle air brick core.
Background technology
In iron and steel metallurgical industry, molten steel enters after ladle, by being blown into noble gas in molten steel, reaches uniform molten steel temperature and chemical composition, promotion inclusion floating or controls the purpose of inclusion morphology, is the commonly used technology of modern metallurgy industry. The method realizing these means at present is to install air brick at ladle bottom, has the advantages such as mixing effect is good, simple to operate, with low cost, and therefore air brick has become as the modern requisite functionalization ventilated element of metallurgy industry.
The metal tail pipe etc. that air brick is generally comprised air brick core, wraps up the steel bushing of air brick core, fills the fire clay in gap between air brick core and steel bushing, is connected with steel bushing by metal cover board. In the use procedure of air brick, at high temperature easily there is the situation of softening in steel bushing, then can be melted close to molten steel part; No matter the relative refractory material of fire clay between steel bushing and air brick core is corrosion resistance or refractoriness, all relatively poor, under the bump of high-temperature molten steel and the corrosion function of slag, easily occur that air brick chamotte mortar joint oozes steel, light then fusing air brick core metal cover plate, metal tail pipe etc., heavy then cause that air brick core issues in the crunch of molten steel and give birth to heavy, and there is bleed-out accident, cause heavy losses.
Utility model content
The purpose of this utility model is for solving under the bump of high-temperature molten steel and the corrosion function of slag, easily occur that air brick chamotte mortar joint oozes steel, light then fusing air brick core metal cover plate, metal tail pipe etc., heavy then cause air brick core the crunch of molten steel issue give birth to heavy, and there is bleed-out accident, the problem causing heavy losses, it is provided that a kind of ladle air brick core.
This utility model is the deficiency solving above-mentioned technical problem, be the technical scheme is that
A kind of ladle air brick core, including air brick A, air brick A offers bellmouth, and be provided with in bellmouth air brick B, air brick B stretch into the one end in air brick A and between air brick A interval formation air chamber is set, the conical surface of air brick B scribbles fire clay formed flame retardant coating, the steel bushing surrounding the air brick B conical surface it is arranged with on outside fire-resistant mud layer, air brick B is away from being provided with metal cover board on one end of air chamber, metal cover board is fixed on steel bushing, and is connected to tail pipe on metal cover board.
Described tail pipe is welded on metal cover board.
The lateral surface of described steel bushing scribbles fire clay.
Described ladle air brick core, including air brick A, has an air brick B at air brick A afterbody inner chamber, and its air brick B is made up of the chamotte between air brick refractory material, steel bushing, steel bushing and air brick refractory material, metal cover board and metal tail pipe; The size of air brick A, B, breathable manner etc. are not limited by this utility model;
Described ladle air brick core, does not use steel bushing and fire clay around air brick;
, there is air chamber at air brick B and air brick A cross section contact position in described ladle air brick core.
The beneficial effects of the utility model are:
(1) this utility model air brick core outer layer does not use steel bushing and fire clay, it is possible to strengthens the safety of air brick, and can reduce its production cost;
(2) use of the present utility model is in extensive range, and its embodiment is not by the restriction of air brick material and breathable manner;
(3) this utility model can be used as overall brick, it is possible to as split brick, the suitability is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Graphical indicia: 1, air brick A, 2, air brick B, 3, air chamber, 4, metal cover board, 5, fire clay, 6, steel bushing.
Detailed description of the invention
Shown in Fig. 1, detailed description of the invention is as follows:
A kind of ladle air brick core, including air brick A1, air brick A1 offers bellmouth, and in bellmouth, it is provided with air brick B2, air brick B2 stretch into the one end in air brick A1 and between air brick A1 interval arrange formation air chamber 3, the conical surface of air brick B2 scribbles fire clay 5 and forms flame retardant coating, the steel bushing 6 surrounding the air brick B2 conical surface it is arranged with on outside fire-resistant mud layer, air brick B2 is provided with metal cover board 4 on the one end away from air chamber 3, metal cover board 4 is fixed on steel bushing 6, and is connected to tail pipe on metal cover board 4.
Described tail pipe is welded on metal cover board 4.
The lateral surface of described steel bushing 6 scribbles fire clay 5.
In conjunction with Fig. 1 one ladle air brick core, including steel bushing, fire clay etc. used by air brick A, air brick B, air chamber and air brick B, there is air chamber between air brick A and air brick B, in air brick B, be embedded with secure ID.
First air brick B is produced, after its conical surface is smeared fire clay, installation steel bushing, use metal cover board metal tail pipe is connected with steel bushing, can before molding air brick A just air brick B be assembled into mould, its air chamber place place combustible, combustible is fixed banding Organic substance, and be uniformly distributed, then carry out moulding by casting, after burning till, namely welding tail pipe, metal cover board make this utility model, and its combustible can reserve air chamber after burning.
Or smear fire clay in air brick B steel bushing topcoating, after its conical surface is smeared fire clay, installation steel bushing, metal cover board is used to be connected with steel bushing by metal tail pipe, fire clay is smeared at its steel bushing outer wall, it is assembled into the air brick A being prefabricated into, having air chamber between air brick B and air brick A, namely welding tail pipe makes this utility model.
In the use procedure of ladle, along with the increase of access times, the height of air brick A declines, and when using to plenum section, air brick B exposes, and for safety, air brick can be stopped using.
Technical scheme cited by this utility model and embodiment non-limiting, be equal to the technical scheme cited by this utility model and embodiment or effect same approach be all in the scope that this utility model is protected.
