Abstract
A kind of ventilative brick structure of disperse; it is to carry out structure optimization on the basis of currently traditional disperse air brick; technical characteristic is to paste two pieces of ceramic protection boards through high temperature firing in the surrounding of former disperse ventilation block or two sides of opposition; to play the role of being effectively protected disperse ventilation block, it is effective and avoids being broken and reducing the risk that molten steel is washed away and is lost.
Description
Technical field
The utility model relates to the Argon air bricks of Refractory for Ladle field, especially refinement outside-furnace.
Background technique
Refinement outside-furnace technique is the most key one of the process of Ferrous Metallurgy, and key position is bottom blowing ar system,
Core element is BOTTOM ARGON BLOWING air brick.
Steel ladle bottom argon blowing air brick is generally made of ventilating seat brick and porous core two parts, is divided into monolithic devices and fitted outside two
Kind, the meaning of ventilating seat brick is that porous core is effectively protected, and porous core is then that the medium element of argon gas is provided into ladle.
Porous core by with air supply channel ontology refractory material and metal shell and rear cover and tail pipe assemble or welding and
At the form of air supply channel is generally by slit class and two kinds of disperse class at present, the former is usually to be poured, disperse class air brick
Core part be disperse breathable block, by mechanical pressing, wherein form disperse shape gap to realize the function of ventilation, therefore,
Intensity, the erosion resistibility of disperse breathable block itself etc. are all relatively weak, and disperse class air brick is suitble to refining in use
Condition is harsher, and steel slag complicated pluralism and the working condition for usually contacting, covering air brick surface are usually unable to reach higher
Service life, main cause is disperse breathable block not resistance to erosion, also frequent the case where being broken, in response to this, from disperse
Class is breathed freely, and it is necessary to optimize for brick structure itself.
The major structural types of current disperse air brick are column disperse ventilation blocks on the pedestal of refractory material prefabricated,
The two is wrapped up by corundum pouring material, and packet, weldering metal shell and tail pipe after drying, as patent 201520819368.0,
201621031300.7,201710219358.7, because the corundum pouring material of package disperse ventilation block can not the reason of structure
High temperature firing, it is not complete enough to the protection of disperse ventilation block that corundum pouring material has been doomed in some calorifics variation in use
Beauty.
Summary of the invention
To solve above-mentioned deficiency, the technical scheme adopted by the utility model is
1, air brick refractory portion is by disperse ventilation block, ceramic protection board, ventilative pedestal, several parts of surrounding castable
It constitutes, ceramic protection board is close to disperse ventilation block side by corundum fireproof mud and forms one and seat on pedestal, ceramics
Can also be directly against between protection board and disperse ventilation block, it is not necessarily to refractory wass, is with castable around outside.
2, the height of ceramic protection board is less than or equal to the height of disperse ventilation block, and quantity is tightly attached to disperse ventilation when being two
The opposition side of block, quantity are tightly attached to four sides of disperse ventilation block when being four, the width of ceramic protection board is less than or equal to
The width in the disperse ventilation same section of block, two of ceramic protection board can also arrange venting slit or venthole on big side.
3, ceramic protection board is using corundum as primary raw material, and through mechanical pressing, 1550 DEG C -1750 DEG C are fired, thickness
For 6mm-20mm.
The beneficial effects of the utility model are:
1, the ceramic protection board of high temperature firing is with good performance, can be effective compared to the castable in Normal practice
Protect disperse ventilation block.
2, the settable venting slit in the big side of ceramic wafer is further to guarantee that air brick is ventilated for argon if setting slit
Ability.

Specific embodiment
Embodiment one:
1, disperse ventilation block is suppressed according to conventional methods, and spare after drying, firing.
2, pedestal is made with the method for casting, and spare after being conserved, being dried.
3, make ceramic wafer protection board:
The plate diamond spar 82% of 3.1 raw materials 0-1mm specification, alpha-aluminium oxide micro mist 5%, the plate diamond spar fine powder of 320 mesh
10%, refractory clay 3%, additional saturation sloppy heat type polyvinyl alcohol saturated solution 4%；The plate diamond spar particle of 0-1mm is reordered
Alpha-aluminium oxide micro mist, plate diamond spar fine powder, clay mixed grind 5min is added after the poly-vinyl alcohol solution mixing completely of amount；
3.2 are formed using hydraulic press, and pressure 150MPa, ceramic protection board is with a thickness of 10mm；
Green body after 3.3 compression mouldings is placed in the support plate with gas permeability slowly heat up up to 150 DEG C at a temperature of
3h is kept the temperature, baking is completed, when baking strictly prevents ceramic protection board from deforming；
3.4 the ceramic protection board of drying is kept the temperature at a temperature of 1600 DEG C of highest 2h firing after complete the production.
4 are bolted together ceramic protection board with disperse ventilation block using refractory wass, and chamotte thickness is no more than 0.3mm,
It is fixed after 120 DEG C are dry with pedestal, is placed in air brick metal shell, is integrally attached to above-mentioned on shake table, perfusion week
Castable is enclosed, finally by maintenance, drying.
5 complete the production the product of accomplishing after drying by welding air brick rear cover and tail pipe.
Embodiment two:
1-3 is the same as the step 1-3. in embodiment one
4 are directly bolted together ceramic protection board and disperse ventilation block, and the high-strength nylon yarn of 0.5mm is no more than with diameter
Twice are tied up, the two is formed into an entirety, are then placed in air brick metal shell with pedestal fixation, it will be above-mentioned whole fixed
On a vibration table, surrounding castable is perfused, finally by maintenance, drying.
