High Alumina Refractory Castable for blast furnace

Refractory castable,High alumina refractory castable,Alumina refractory castable

introduction :

Refractory castable is one of the unshaped refractory materials.It is made of refractory aggregate . refractory powder . binders and other additives. It is loose, No fixed shape,Has high liquidity, Casting and vibration molding,Can use directly or use after add appropriate water or other liquid. It is one of the new type refractory material of don't need calcination. In general the use of the site casting, vibration or tamping pouring molding method, a preform can also be made pre-formed components.

Features:

1. High refractoriness, High refractoriness under load.
2. High density, low porosity.
3. Good slag resistance and corrosion resistance.
4. High strength and wear resistance.

5. Good resistance to flake performance.

6. Good thermal shock stability.

7. Scouring resistance

$High Alumina Refractory Castable For Blast Furnace$

Q:Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?: Many enterprises need refractory materials. You can go to Mianyang large private enterprises to askSupermarkets, stations, hotels are required

Q:What are included in fireproofing materials?: There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire?retardant material and its products, textile, fire?retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof?panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof?sealing?material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of?toxic?gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire?rating, etc. There are some specific parameters which need to be judged by a professional testing equipment. You can go to the inorganic laboratory to check. The test results of fire rating are accurate.

Q:For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?: It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned?brick whose cememting agent is phosphoric?acid or aluminium?phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.

Q:what is the Specifications Grading for Fireproof rubber insulation materials ?: External insulation materials, welded wire mesh matt external wall insulation, external wall thermal insulation mesh matt. 1,inorganic activel thermal insulation materials 2,silicate?thermal?insulation?material 3,ceramic thermal insulation 4, gelatine powder polyphenyl granule, 5,teel wire gauze picking cement cystosepiment（Estazolam platepowder particles)6 extruded sheetXPX. 7,Rigid polyurethane coating at the scene, Polyurethane insulation board8,rigid polyurethane foam,9EPS foam board roofing materials. 1, a ceramic insulation board 2, xps extrusion board 3, perlite and perlite brick 4, vermiculite and vermiculite brick heating, air conditioning Material: Phenolic resins, polyurethane waterproof thermal insulation integration, sponge rubber, polyethylene, polystyrene foam, glass wool, rock wool Steel material: Polystyrene, extruded sheet, polyurethane panels, glass wool carpets and the like. Five inorganic thermal insulation materials: Foam cement, DY inorganic active insulation system super thin vacuum insulated panel for building external walls .

Q:Can quantitative feeder be used in refractory plant? Thank you: Well, can the Weifang Sanyou automation equipment production chain plate feeder is fully applicable to the measurement and control of boring high temperature, chain plate feeder with 16 4-5MM manganese plate.

Q:Which basic refractory is better?: 1 Zibo Quanxing Refractories Plant, factory direct, quality assurance, best price, off the shelf. 2 Zibo Huadian Refractories Co.,Ltd. one package service from research, production, sale to construction, our trust!

Q:What are the types of refractory sealant?: 1. The characters of sealant for construction According to the characters, sealant for buildings are classified into caulk, sealants and construction sealant in China; They are named in accordance with the function and different basepolymeters. In the relevant standard for products,

Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?: glass

Q:Technical scheme of refractory for refuse incinerator: Incinerator conditions and requirements for refractory lining1, working conditions: deal with rare earth, furnace body normal use temperature of 800~900 degrees.2, the specific requirement for refractory: refractory has good resistance to acid corrosion, thermal shock performance good stability and good high temperature.

Q:can slag tailings be used to be the base materials of refractory materials ?: perhaps not, because it has many pores.
