Description
The present invention relates to a kind of antioxidant of carbonaceous refractory materials, particularly a kind of carbon containing refractory.
Magnesia carbon brick, aluminum-carbon brick, Al2O3MgOC Bricks, carbon containing refractories such as magnesia-calcium-carbon brick are generally as electric arc furnace, converter, the furnace lining of metallurgical furnaces such as ladle, the one of the main reasons of these refractory corrosions is oxidations at high temperature, promptly before these metallurgical furnaces use, all to carry out long baker, furnace lining contacts with air for a long time, cause the furnace lining oxidation to form thicker zone of oxidation, in the baker process, to form the Decarburized layer of about 30mm as converter, this Decarburized layer is no intensity, porous does not have carbon-coating, when containing molten steel, can be fallen by molten steel scouring, the general every refining one heat steel of converter furnace lining will be etched 0.2~0.6mm, therefore owing to making, the baker oxidation reduces nearly 100 heats the work-ing life of furnace lining, the non-Sheng molten steel time of these metallurgical furnaces in operation process has had a strong impact on the work-ing life of carbon containing refractory because the furnace lining oxidation also can cause the quick erosion when containing steel simultaneously.In order to improve the work-ing life of carbon containing refractory, carried out big quantity research in the prior art, normally in carbon containing refractory, add strong reducible agents such as metallic aluminium powder, magnesium aluminum-alloy powder, silica flour and carborundum powder, thereby improved the oxidation-resistance of carbon containing refractory.For example to disclose a kind of " not burning magnesia carbon brick " be at graphite 5~50% to the clear 61-215250 of Japanese Patent Application Laid-Open, 2~10% 1 kinds of the refractory materials addings or the phosphoric acid salt additive more than 2 kinds of electrosmelted magnesite clinker 50~95% are polyphenoils, but the reaction of the wedding agent carbon of this antioxidant and carbon containing refractory descends the mechanical behavior under high temperature of refractory materials.
The objective of the invention is to obtain a kind of antioxidant of carbon containing refractory, can improve its oxidation-resistance and the not influence of the mechanical behavior under high temperature of refractory materials.
For achieving the above object, the technical solution of the present invention's proposition is:
A kind of antioxidant of carbon containing refractory, by zinc, or at least a composition in zinc and aluminium, magnesium, silicon, silicon calcium powder, silicon carbide, norbide, magnesium aluminum-alloy powder, the silicon nitride powder.
Above-mentioned raw materials is Powdered.
The granularity of zinc powder is less than 0.5mm.
The granularity of zinc powder is less than 0.15mm.
The zinc powder of carbon containing refractory 0.15~10% (weight), the perhaps mixture of at least a composition in the zinc of carbon containing refractory 0.15~10% and aluminium, magnesium, silicon, silicon calcium powder, silicon carbide, norbide, magnesium aluminum-alloy powder, the silicon nitride powder, wherein zinc powder 〉=0.15%.
Account for the zinc powder of carbon containing refractory 0.15~4%, perhaps account for the mixture of at least a composition in the zinc of carbon containing refractory 0.15~6% and aluminium, magnesium, silicon, silicon calcium powder, silicon carbide, norbide, magnesium aluminum-alloy powder, the silicon nitride powder, wherein zinc powder 〉=0.15%.
Below the present invention is done and be described in further detail.
The antioxidant of the carbon containing refractory that the present invention obtains, its key problem in technology are that the mixture that adopts metal zinc or zinc and other component to form is an antioxidant, and wherein each components contents and the mechanism of action are:
Zinc powder: 0.15~10% (weight, as follows), because zinc can be under the metallurgical furnace storing temperature, be gasificated into the gas of high partial pressures, zinc is not very strong to the avidity of oxygen simultaneously, this vapor diffusion that can make it is to Decarburized layer, and because it has certain avidity to oxygen, this will make at Decarburized layer and be oxidized to ZnO; Zinc oxide is dystectic oxide compound, so it does not reduce the anti-corrode performance of material, and the price comparison of zinc is low.
The mixture of at least a composition in zinc and aluminium, magnesium, silicon, silicon calcium powder, silicon carbide, norbide, magnesium aluminum-alloy powder, the silicon nitride powder: 0.15~10%, zinc powder 〉=0.15% wherein.Add acting as of other component: when further guaranteeing its oxidation-resistance, improve the mechanical behavior under high temperature of refractory materials, wherein aluminium powder, silica flour, silicon calcium powder, magnesium aluminum-alloy powder also can improve its resistance to fouling.
Optimal components of the present invention is: the zinc powder of carbon containing refractory 0.15~4% (weight), the perhaps mixture of at least a composition in the zinc of carbon containing refractory 0.15~6% and aluminium, magnesium, silicon, silicon calcium powder, silicon carbide, norbide, magnesium aluminum-alloy powder, the silicon nitride powder, wherein zinc powder 〉=0.15%.
Prior art is normally added strong reducible agents such as metallic aluminium powder, magnesium aluminum-alloy powder, silica flour and carborundum powder in carbon containing refractory, thereby has improved the oxidation-resistance of carbon containing refractory.Mechanism that it is generally acknowledged these antioxidants is: compares with carbon, and the easier oxidation of these additives, and generate more volume after the oxidation, stop up pore, thereby improved the oxidation-resistance of carbon containing refractory.But this oxidation-resistance mechanism can not be explained CaO and water in air reaction generation comparatively large vol Ca (OH) in the magnesia-calcium brick
2The time, the void content that not only can not reduce product increases the fact of void content on the contrary.The present invention has studied its oxidation-resistance mechanism, and the result shows: in carbon-containing bed, these additives and carbon effect generate the very low Al of dividing potential drop
2O, SiO, Mg gas, these strong reducing gass will oxidation generate high temperature solid-state MgO, Al to external diffusion at the Decarburized layer than strong oxidizing property atmosphere
2O
3, SiO
2, these oxide compounds are deposited in from gas phase on the gas passage, have stopped up gas passage, have improved the oxidation-resistance of carbon containing refractory.Because, Al
2The dividing potential drop of O, SiO is very low, thus metallic aluminium powder, silica flour, carborundum powder to be used for the antioxidant effect of carbon containing refractory unsatisfactory.For the magnesium powder, though the evaporation dividing potential drop of Mg is very high, the avidity of it and oxygen is strong especially again, does not become gas toward contact and just has been oxidized to MgO, and the oxidation-resistance of carbon containing refractory of therefore adding MAGNESIUM METAL is also undesirable.
For the carbon containing refractory that adds boron glass, make the apparent porosity reduction and oxidation-protective effect is preferably arranged though in carbon containing refractory, become liquid phase, because it is the flux of material of main part, the anti-corrode of material is obviously descended.
For the antioxidant that obtains to guarantee the oxidation-resistance of carbon containing refractory and do not reduce anti-corrode performance, the present invention is by making the research of the antioxidation mechanism of carbon containing refractory to additive, and fusing point, the boiling point of all metals and oxide compound thereof compared analysis, they and C, CO, CO
2And O
2The thermodynamics free energy of reaction is analyzed, and finds out the antioxidant that metallic zinc is only carbon containing refractory.
Introduce embodiments of the invention below in conjunction with effect.
