The service life of skinning loam, reduces costs.
Lack the coating for being exclusively used in fish torpedo ladle permanent layer in the prior art.
Summary of the invention
The object of the present invention is to provide a kind of fish torpedo ladle permanent layer coatings, mainly solve the thermally conductive system of existing fish torpedo ladle
The technical problem that number is high, transport molten iron process hot metal temperature drop is big.
The technical scheme is that a kind of fish torpedo ladle permanent layer coating, the weight percent of raw material components are as follows:
Lightweight alumina 55%~65%, microballon 5%~10%, pure calcium aluminate cement 13%~24%, magnesia 4-5%, silicon powder
3%~8%, the sum of weight percent of the raw material components is 100%.
The reasons why component of fish torpedo ladle permanent layer coating of the present invention limits within the above range is as follows:
Because the permanent layer of fish torpedo ladle, working lining are all made of Al-Si Refractory Materials and are made, fish torpedo ladle permanent layer of the present invention is used
Coating is using based on aluminium silicon matter, to prevent reacting for alkaline matter and acidic materials.
Lightweight alumina: using lightweight alumina as coating aggregate, the chemical component of lightweight alumina is the present invention
Al2O3·H2O, Al2O3·3H2O and a small amount of Fe2O3·SiO2, it is commonly used for manufacturing refractory material, elevated temperature strength is high, resists molten
Scouring ability is strong, is widely used in the industries such as steel, coloured, the bulk density 2.7-2.9g/cm of common alumina3, the present invention
The bulk density used is 2.0-2.2g/cm3Therefore referred to as lightweight alumina.
Lightweight alumina is the oxide of aluminium silicon systems, and fusing point is 1800 DEG C, and price is relatively cheap.Due to common alumina
Thermal conductivity is high, and present invention employs lightweight alumina, bulk density 2.0-2.2g/cm3If excessively high in coating,
Constructional difficulties；If content is too low, material property changes, and cannot effectively support working lining and compress to its intensity.It is ground for many years
Study carefully, the weight percentage that the present invention controls lightweight alumina in coating is 55%~65%；For the ease of constructing and guaranteeing
Construction quality, the present invention control partial size≤5mm of lightweight alumina.
Microballon: cenosphere is used in order to further decrease the thermal coefficient of invention material, the chemical component of microballon is
Sodium silicoaluminate (Na2O·Al2O3·2SiO2·H2It O), is a kind of global shape, the fine microballon of continuous ionic exchange, particle size is not
Together, the present invention is less than or equal to 10 μm using partial size, and microballon forming process is that silica, aluminum oxide are reacted with sodium hydroxide
The sodium silicoaluminate of indissoluble is generated, chemical equation is 2SiO2+Al2O3+ 2NaOH=Na2O·Al2O3·2SiO2·H2O, it is hollow
The effect for reducing thermal coefficient is not had if microballon additional amount is very little, is added too much, material intensity after molding, which is not achieved, to be wanted
It asks, is studied for many years, the weight percentage that the present invention controls microballon in coating is 5%~10%；For the ease of construction and
Guarantee that construction quality, the present invention control partial size≤10 μm of microballon.
Magnesia: having gelling characteristic using magnesia (MgO), with addition of a certain amount be conducive to enhance its adhesion from
And its rebound rate is reduced, and additional amount cannot be excessive, excessively then destroys original ingredient, and it is too low, due effect is not had, is passed through
It studies for many years, the weight percentage that the present invention controls magnesia is 4-5%.
Pure calcium aluminate cement: the set strength in order to enhance coating is combined using pure calcium aluminate cement in the material
Agent is studied for many years, and the weight percentage that the present invention controls pure calcium aluminate cement is 13%~24%.
Silicon powder: the combination of coating of the present invention is by the way of Coagulating binding, by fine aluminium when the Coagulating binding of coating
Sour calcium cement and silicon powder are realized jointly, in order to enable coating, which quickly adheres to, forms an entirety with torpedo tank liner original brick,
Using silicon powder, the aluminum oxide contained in the silicon powder and raw material in instant component, which reacts, generates aluminium silicon spinel
(2Al2O3·3SiO2), chemical equation is 3SiO2+2Al2O3=2Al2O3·3SiO2。
Further coating and torpedo tank liner is promoted to form entirety, since silicon powder has been catalytic action, content
It should not be too high；It is studied for many years, the weight percentage that the present invention controls silicon powder is 3%~8%.
The preparation method of coating of the present invention, comprising:
1) by coating with comparing lightweight alumina and pure calcium aluminate cement carries out weighing ingredient, with kolleroang by light weight
Change alumina and pure calcium aluminate cement carries out mixing 5~10 minutes；
2) weighing ingredient is carried out with comparison microballon, magnesia, silicon powder by coating；
3) microballon, magnesia, silicon powder and lightweight alumina and pure calcium aluminate cement are mixed 15~20 points with kolleroang
Clock obtains coating finished product, is packed into finished bag.
The construction method of coating of the present invention is:
Fraction of water is added in coating, is advisable in order to smear, amount of water is controlled 2~3%, in fish torpedo ladle slack tank
In the state of, coating is applied in fish torpedo ladle steel by the common anchoring piece for the 10cm long that burn-ons on fish torpedo ladle slack tank inner wall
At wall, smeared using multilayer, until smear the bed of material with a thickness of 210cm, rest 14 hours, the permanent layer of fish torpedo ladle be made；Afterwards
The working lining of fish torpedo ladle is built in the permanent layer surface of fish torpedo ladle.
The present invention uses fish torpedo ladle permanent layer made of coating in 600 DEG C of thermal coefficients for 0.232-0.245W/ (m
K), fish torpedo ladle permanent layer made of existing clay brick is the left and right 0.732W/ (mK), the use of the two in 600 DEG C of thermal coefficients
Service life is suitable.
