Description
Technical field
The invention belongs to technical field of refractory materials, and in particular to a kind of modified form steel-making air blowing refractory component.
Background technique
Now widely used steel-making air blowing refractory component mainly has two kinds of structure types.One of which is slit knot
Structure mainly uses pre-buried fine linear Plastic eutectic, by vibration or mechanical pressing, in 200-300 DEG C of drying process
In, pre-buried fine linear Plastic eutectic fusing forms micro-channel.The air blowing element of slit structure the disadvantage is that: steel
Water penetration hinders being blown into for gas into slit, and the bubble in addition blown out attacks the surface of brick in retaliation, seriously washes away brick body surface.
Second is disperse structure, using vibration moulding, makes the porosity in 25-35% or so, a kind of integral dispersion structure is formed, with true
Gas is protected to pass through.The shortcomings that disperse formula structure is, since the size of stomata is not easy to control, to will cause Air permenbility unevenness, blow not
Easy to control, in addition under the action of thermal shock and rapid heat cycle, surface texture is easily destroyed, and structure becomes loose, in molten steel and
Peeling is generated under the washing away of air-flow.These are unfavorable for the popularization for making steel concise new process.
The patent No. thus: CN201420107546.2 discloses " steel-making air blowing refractory component ", and bottom is equipped with air inlet pipe
Conical steel shell, fire resisting gas permeable center seat and fire resisting breathe freely plate or combinations thereof, the fire resisting gas permeable center seat and fire resisting
Ventilative plate or combinations thereof is sequentially connected, through refractory clay setting in the conical steel shell, the fire resisting gas permeable center
Seat is set to conical steel shell bottom and linking corresponding with air inlet pipe, and ventilative plate of the fire resisting or combinations thereof lower end is correspondingly connected with
The fire resisting gas permeable center seat.But program chamber volume is smaller, not can guarantee the flow and percent of pass of gas, influences to blow
Efficiency.
Summary of the invention
The purpose of the present invention is to provide a kind of modified form steel-making air blowing refractory components, it is intended to solve existing steel-making with blowing
The problem of chamber volume of gas refractory component is smaller, not can guarantee the flow and percent of pass of gas, influences air blowing efficiency.
To achieve the above object, a kind of modified form steel-making of the invention is adopted the following technical scheme that with air blowing refractory component
Air inlet pipe including conical steel shell He its bottom is provided with refractory clay, fire resisting gas permeable center seat and resistance in conical steel shell
The bottom of the ventilative plate of fire, the cone steel shell is provided with chassis, and chassis is connect with air inlet pipe, and setting is fluted on the inside of chassis
Gas chamber is formed with fire resisting gas permeable center seat.
The groove be it is along the circumferential direction uniformly distributed multiple petal, each petal forms a gas chamber, adjacent petal it
Between be equipped with reinforcing rib.
The groove is made on chassis using one time punching molded.
Single head or multi-head spiral groove are provided at the respective slot of the fire resisting gas permeable center seat bottom surface.
The fire resisting gas permeable center seat top surface corresponds to and is provided with concentric circles annular groove at the ventilative plate of fire resisting.
The chassis is welded by reinforced pipe and air inlet pipe, is reinforced pipe diameter and is greater than air inlet pipe diameter.
The beneficial effects of the present invention are: air blowing refractory component of the invention, on the basis of existing technology, by chassis
Upper setting petal connected in star, increases the volume of gas chamber between fire resisting gas permeable center seat and chassis, in the premise for guaranteeing structural strength
Under improve the flow and percent of pass lifted；Increase a major diameter reinforced pipe between chassis and air inlet pipe simultaneously, ensure that
The connection structure intensity on chassis and air inlet pipe is prevented from carrying and be fallen off in use process.
