Specifications

Sintered silicon nitride bonded SiC refractory plate
1.Density:2.65g/cm3
2.Max temperature:1700C
3.Bending strength:>45Mpa

Silicon Nitride (Si3N4) bonded silicon carbide (SiC) material is a new type of advanced refractory materials. Compared with silicon carbide product, the product has characteristics of small thermal expansion, high thermal conductivity, not easy to have thermal stress, good thermal shock resistance, corrosion resistance, extreme cold or heat, oxidation, high temperature creep resistant ability and easily made into products with high dimensional accuracy requirements in line. Silicon nitride combined silicon carbide products have very high strength for normal atmospheric temperature, and it remains almost the same time with the strength and hardness at high temperature 1200-1400C. with the difference of using atmosphere, the maximum safe operating temperature could reach 1650-1750C.

Ceramic kiln shelf,panels,pillars,seperated flame plate,Waste Incineration Furnace Lining,aluminum tank.

All products are produced to the highest quality standards which means the consistent supply of ceramic components to enable your process to run more efficiently.
All components are supplied with a replacement guarantee. This guarantee provides for the replacement of the component if the service life is reduced because of a fault in the manufacturing process.

Typically we offer a guarantee of 40 days life in service for a riser tube in a low pressure aluminum die casting application, depending on the design. Our experience has shown that the design of the riser tube has an effect on the operational life. We can call on our experience and advise on the design of components to ensure the longest possible life for ceramic parts in your equipment.

Q: Technical scheme of refractory for refuse incinerator: The equipment shall be subject to the construction of refractory materials after acceptance by the relevant personnel.The furnace body is divided into two parts: the construction of a refractory material are respectively first half brick masonry, steel shell near the first building refractory clay brick masonry to both sides from the middle to the lowest height semicircle, clay brick masonry completed all started after graphite brick masonry, also to the semicircle; after the completion of the second half part of all the brick masonry, began laying it on the semicircle: first set semicircular pattern suggested pattern width is 1 ~ 2 brick masonry first width, graphite brick, clay brick masonry and masonry, from both sides to the middle, laying a piece of graphite brick masonry clay brick.

Q: What are some of the new refractories and what are their characteristics?: Refractory common AZS refractories are often used brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, beryllium oxide and other refractory materials, Magnesium Oxide

Q: How is the division of the fire resistant level of the rock wool board?: It's like this: China's national standard GB8624-97 divides the combustion performance of building materials into the following grades. Level A: non-flammable building materials. Level B1: flame-retardant building materials. Level B2: combustible?building?materials. Level B3 flammable building materials. section II Combustion performance and fire endurance of building components. First, The combustion performance of buildings of building components. The building is composed of components, such as foundation, walls, lubrication columns, beams, plates, roofs and stairs, ect. Building components are constituted by the building materials, whose combustion performance depends on the combustion properties of the used construction materials. Section One Combustion performance of building components. The building components are divided into three categories according to their combustion properties. First, non-combustible component: the component made by incombustible?materials. The incombustible?material refers to that when meeting the Oxygen in the air, it will not burn.

Q: What is the function of refractory in ceramics?: In addition, the quality of refractory determines the finish and color of ceramic glaze.

Q: Who knows the external wall thermal insulation materials fire rating requirements?: The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height

Q: What are Grade-A waterproof inorganic thermal insulation materials?: Grade-A waterproof inorganic thermal insulation materials include: 1. external wall thermal insulation materials: (1) silicate thermal insulation material (2) gelatine powder polyphenyl granule (3) steel wire gauze picking cement cystosepiment (Estazolam plate) (4) extruded sheet; 2. roofing materials: (1) XPS Extruded sheet (2) EPS cystosepiment (3) perlite and perlite bricks (4) vermiculite brick; 3. heating and air conditioning material: PUR, rubberplastic sponge, polystyrene foam, glass wool, rock wool; 4. steel structure material: polystyrene, extruded board, polyurethane board, glass wool roll mat, etc.

Q: What refractories can withstand high temperature above 2100 degrees?: But the price is more expensive, while the insulation performance is not as good as common materials. Is there a material that can withstand 2100 ℃? Currently, the long-term use temperature of the best refractory bricks is about at 1800 ℃, while materilas that can withstand a temperature of 2100 ℃ are relatively rare in the production.

Q: Who knows the fire endurance of B-level fireproof doors and windows?: B-grade fireproof windows refer to those fireproof windows whose fire retardant limit is not less than 1 hour. Technical requirements: I. Materials and Accessories (1) Window frame should have a certain strength to ensure the integrity and stability of the steel frame or the wood frame. (2) Steel frame and mound layer can employ galvanized?steel?sheet or stainless steel plate. Its selection criteria should be in line with the stipulation of the Article 5.1 of GB12955 "General Technical Requirements of Steel Fireproof Doors". (3) The selection standard of wood frame and mound layer should be in line with the provision of Article 5.1.1 of GB14101 "General Technical Requirements of Wooden Fireproof Doors". (4) Filling materials inside steel frame and wood frame should be non-combustible materials.
