 Use

 

The company produces other kilns with the diameter1-5 meters, widely applies in the metallurgy, the chemical industry, bears professions and so on material, Ceram site, papermaking. This kind of kiln’s supporting is divided into two forms of rolls and skids, the transmission may use direct-current or the exchange frequency conversion velocity modulation, and has many kinds of form seals to adapt the different operating mode.

Our company could also meet different needs from different customer to produce Non-standard kiln.
Rotary kiln is composed of cylinder, gears, supports device, kiln liner and kiln tail sealing equipment, kiln head hood, and combustion.

Cylinder as heated pivoting part, made of high-quality carbon steel plate, is supported on the first or some gear in order to control the turning of cylinder. Gearing gyrate according to process-required rotating speed by ring gear in the middle of cylinder. Because of the need of installation or maintenance, bigger rotary kiln has auxiliary gears, which makes cylinder gyrate more slowly. To prevent cold air come in and dust overflow, the reliable kiln tail and head sealing equipment is installed on feed and discharge end.

Q:What is the concept of lightweight refractory material?
Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
Q:Who knows about the types of Dalian thermal insulating and refractory materials?
There are many Dalian thermal insulation materials, which can be divided into organic and inorganic thermal insulation materials. Materials include inorganic thermal insulation materials, polyfoam, mineral wool products, foam glass, expanded perlite insulation products, gelatine powder EPS grain heat insulating slurry, sprayed mineral wool, thermal insulation product of foam cements, and vacuum thermal insulation board.
Q:Who knows about the B-level fireproof insulation materials?
Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
Q:What types of steel are silicious quicksand and chromium quicksand used in respectively?
Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.
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:Does anyone know about the A-level fireproof materials?
A-level decorative integrated plates of thermal insulation, water- and fire-proofing mainly can prevent fire and insulate heat with A-level fireproofing glass fiber as thermal insulation materials. The classification of A1-level external wall materials of thermal insulation, fire- and water-proofing: First, external wall thermal insulation materials: 1. silicate thermal insulation materials 2. gelatine powder polyphenyl granules 3. steel wire gauze picking cement cystosepiment (grs board) 4. extruded sheets; Second, roofing materials: 1. xps extruded sheet 2. EPS foam board 3. perlite and perlite brick 4, vermiculite and vermiculite bricks; Third, heating and air conditioning materials: Polyurethane, rubberplastic sponge, polyethylene, polystyrene foam, glass wool, rock wool; Four, steel structure materials: Polystyrene, extruded sheet, Polyurethane board, glass wool roll mat, etc.
Q:What material is used to make furnace pipe of refractory bricks?
Refractory bricks furnace pipe material is generally divided into two types, namely, shapeless refractory material and shaped refractory. Shapeless refractory material, also known as castable refractory, is hybrid powder material made up of many kinds of aggregate or aggregate and a kind of or many kinds of binders. It must cooperate and evenly stir with a kind or many kinds of liquids during use and has strong mobility. Shaped refractory material usually refers to refractory brick whose shape has standard rules. It can also be proceeded temporarily during cutting according to requirement.
Q:What is the new fireproofing standard of external wall thermal insulation materials?
The new national standard "Fireproof  Specification of Building Design" (GB50016-2014) has been issued, it will be carried out from May 1, 2015. Compared with "Fireproof  Specification of Building Design" GB 50016-2006 and "fire safety rules of tall buildings design" GB 50045-95 (2005 edition), the major changes of new standard is the following: 1. It has combined with "Fireproof  Specification of Building Design" and "Fireproof  Specification of Tall Buildings Design", and has adjusted incompatible requirements between two standards, and has unified the classification of residential buildings in accordance with the building height; 2. It has increased two chapters including the fire-fighting rescue facilities and wooden structures, and has improved the requirements for fire fighting and rescue, and standardized the fireproofing requirements of wood construction; 3. Additional requirements for the fireproofing requirements of building external insulation system; 4. The fire-fighting equipment is written in a separate chapter and improve relevant contents; cancel the design requirements of fire water supply system and smoke control system, and they are regulated by the relevant national standards; 5. appropriate increase in the high-rise residential buildings and fireproofing technical requirements for high-rise civil building whose height is greater than 100m; 6. add the fireproofing requirements used by covered pedestrian during evacuation; adjust and add designers density of construction materials, furniture, lighting shops and exhibition hall; 7. add the fireproofing requirements of underground warehouses, logistics buildings, large combustible gas tank (zone), ammonia storage tanks, LNG storage tank, and adjust the fire separation distance of liquid oxygen tank; 8. improve the relevant requirements to prevent vertical or horizontal spread of building fire.
Q:How is the development of Xinmi refractories industry? What's its advantages and disadvantages?
The disadvantage is too small yard, vicious competition among each other and confusion in the market, which should be the inferiority of national refractory industry . Xinmi Refractory is well developed in recent years, mostly acidic and neutral refractories. It is still relatively rare to use in iron parts, steel pile with a satin and other basic refractory slide .
Q:What are the requirements of refractory temperature of refractory brick?
Refractoriness can reach 1690 degree, but the highest operating temperature is 1350 degree. If the temperature goes higher, operation life will be greatly shortened.
