Description
Technical field
The present invention relates to technical field of refractory materials, specially a kind of ladle, coke oven, glass furnace etc. of being suitable for needs fire resisting
Field uses.
Background technique
Refractory wass (refractory mortar) is used as the unshape refractory of refractory masonry seam, also known as connects
Sewing.Refractory wass can be divided into the hydraulicity, thermohardening, air hardening refractory mud according to its bonding agent condensation hardening feature；The hydraulicity
Refractory wass is can be used under room temperature or may be with water or steam often in contact with place using cement as bonding agent.Thermohardening is resistance to
Chamotte is starched the common thermohardenings bonding agent such as phosphoric acid or phosphate and is made.It is higher except having at various temperatures after such mud hardening
Other than intensity, contraction is small, and seam is tight, and erosion resisting is strong；Air hardening refractory mud is often matched with the air-settings bonding agent such as sodium metasilicate
System, this mud can make the seam of masonry tight.Different according to the material of refractory powder used, common refractory wass can divide
Are as follows: clayey, High-Alumina, it is siliceous, magnesia, contain carbonaceous, heat-insulated matter, etc..Clay fire-resistant slurry uses hard paste clinker
As base-material, combined with mild-clay or chemical bond.Be mainly used in blast furnace, hot-blast stove, coke oven, soaking pit, heat exchanger,
The furnace body seam and repairing of the clay brick masonry such as boiler.High alumina fire-resistant slurry material of main part selects high alumina, bonding agent
With mild-clay or chemical bond.Al2O3 content is determined according to the brick body ingredient and requirement at built position.It can be extensive
Various Industrial Stoves for high alumina brick masonry.For building furnace roof, regenerative chamber, combustion chamber etc. on hot-blast stove, it to be used for blast furnace
The parts such as furnace bottom, cupola well, bosh, furnace bosh, it may also be used for repair the positions such as industrial kiln top, furnace wall.Silica fire resistant mud is adopted
Main material is done with Cab-O-sil or addition part silicon powder.Bonding agent can use mild-clay or chemical bond.Silica fire resistant mud master
It is used to build and repair coke oven, glass melter, acid smelting furnace etc. and other Industrial Stoves built with silica brick.Magnesia fireproof
Mud uses various magnesia as raw material, is combined with clay, bentonite or chemical bond, or is directly modulated with brine (MgCl2)
Mud.Open hearth, electric furnace, oxygen coverter, smelting non-ferrous metal kiln etc. is mainly used in be built with magnesia brick, magnesite-chrome brick, magnesia-alumina brick etc.
The part built.Carbon containing refractory wass is made by various light-weight refractory powders and bonding agent.Its main feature is that bulk density is small, thermal conductivity
Rate is low, can be used for building and repairing on the various Industrial Stoves built with heat-barrier material.Other refractory wass are except above several resistance to
Chamotte slurry is outer, and there are also silicon carbide based fire clay slurries, porzite flame-proof mud, corundum fireproof mud, zirconium fire-resistant slurry, chromium
Fire-resistant slurry.Its different properties is respectively used to the masonry and repairing of same material refractory brick.Additionally some specific uses
Mud, such as anhydrous (non-aqueous) mud, expansion mud.Make refractory wass powder can be selected the sufficient clinker of sintering and
The various refractory raw materials of other volume stabilities.For the granularity of powder-material depending on requirement, Limit Grain Size is generally less than 1mm,
Some is less than 0.5mm or thinner.Reasonable particle group guarantees that the workability of mud has a significant impact in pairs, bonding agent and additional
Agent is also the same.The bonding agent that common refractory wass uses is bonding clay.With the requirements at the higher level of user, chemical bond is obtained
More and more extensive use is arrived.Various additives are added in refractory wass can improve the workability of refractory wass, such as add
Enter to protect water-proofing agent to extend losing time, guarantees construction quality；Plasticizer is added, mud can be increased in the lesser situation of additional amount
The plasticity of slurry；Dispersing agent is added to improve the mobility etc. of mud.Refractory wass is refractory brick or brick to be connected into a heavily fortified point
Real entirety is essential a kind of unshape refractory during most stoves are built.It will not only bear high temperature work
With, while it will undertake the outer dimension tolerance of adjustment brick, balance the swelling stress between brick.Therefore only using the resistance to of top grade
Chamotte slurry, can just obtain the kiln of high-efficiency long-life.
Siliceous mud powder is the binding material of refractory brick, and builds the binding material of the high-temperature furnace bodies such as coke oven, it
Performance directly affects the masonry quality and service life of refractory brick and furnace body.Currently, people use always native mud, it is such as certain
Then manufacturer mixes with the residual silica brick of a small amount of each production silica brick producer using tripoli as primary raw material and natural mud is made
Starch since the primary raw material of native mud is tripoli, exists in actual use with silica brick used in the furnace bodies such as coke oven is built
It is had differences in material, although also containing a small amount of residual silica brick in ingredient, due to the otherness in area, so that preparing mud
There is also differences in material for silica brick used in the furnace bodies such as the residual silica brick and masonry coke oven of starch, therefore go out in the construction process
Native mud at low ambient temperatures and silica brick bonding and under high temperature environment inadherent phenomenon are showed, to high temperature furnaces such as coke ovens
Production from now on brings great hidden danger.
Summary of the invention
The present invention provides one to solve the problems, such as that existing siliceous mud powder is mutually inadherent during practical applied at elevated temperature
Kind fire-resistant slurry powder.
The present invention is achieved by the following technical scheme: fire-resistant slurry powder is made of the raw material of following weight percents:
Silica 46-48%, SiO2 content of the SiO2 content not less than 96% is not less than 92% residual silica brick 46-48%, and Al2O3 content is not
The graphite of fire clay 3-8%, 0.05-0.09% lower than 25%, the phenol-formaldehyde resin powder of 0.03-0.05%；The residual silicon
Brick is consistent with the silica brick material that the fire-resistant slurry powder is built.
The heat cured phenol-formaldehyde resin powder of heat-resistant fireproof makes the adhesion strength of refractory wass be able to maintain higher temperature,
Improve the medium and high temperature adhesion strength of mud.
The residual silica brick refers to truncation, unfilled corner in finished product silica brick, has the shapes such as crackle, in appearance defective substandard products,
The substandard products not reached requirement without referring to its physical and chemical index, so that guarantee is prepared used in residual silica brick and the masonry of mud powder
Silica brick is consistent in material.
The invention has the advantages that using phenol-formaldehyde resin powder make refractory wass adhesion strength be able to maintain it is higher
Temperature, improves the medium and high temperature adhesion strength of mud, and residual silica brick is utilized, and realizes maximally utilizing for waste material, extends
The service life of ladle and furnace body, uses suitable for high-temperature furnace body and ladle.
