- Q:What material is used to make furnace pipe of refractory bricks?
- Furnace pipe of refractory brick is an indispensable part of casting cupola. Furnace pipe is divided into upper and lower part. Radial direction and axial breathing. The upper furnace pipe adopts double layer steel structure and countercurrent air supply mode. The lower furnace pipe is made by processing integrated heat resistant steel in flange, fin and inner wall in wearing parts. The operation life is over 3000h. There is radiating rib of heating air on the edge of furnace pipe liner by using the heat of casting cupola to heat air in cupola. Hot air temperature is about 180-250℃, which contributes to improve trhe thermal efficiency of production equipment, decrease production cost and improve economic benefit of enterprises.
- Q:The fire prevention board line is made of what material?
- (1) if it's real wood floor, the line should be made of wood. The ready-made wooden line, walnuts, price range depends on the texture width. The common width is 100 mm. One linear meter is around $17 - $30. Paulownia is cheaper with one linear meter more than 10 yuan. When it is composite wood floor, high-density plate modelling line can be used. The price is commonly between 40 to 80 yuan (2400 x 1200 mm), which depends on the thickness and density and also the factory. There are also imitated wooden aluminium line. (3) if it's the marble ground, you would better use marble line, which is 200 yuan one square meter. It's price is also unequal. The imitated stone is also available. There are a lot of kicking decoration materials and it depends on how you use it. That is to say crural line should be coordinate with the ground. It means that it sjould not only to be beautiful but also to be practical. It would be better if it is relatively cheap as well.
- Q:What antioxidant will be used in refractories?
- Antioxidants (Antioxidants) is the material to prevent bad influence of oxygen. It is a kind of material that can help to capture and neutralize free radicals, the category of material to remove free radicals damage to human body. Some of the body's antioxidant is self-synthesis, others is also from the food supply. Strong antioxidant such as ASTA (short for astaxanthin), etc., generally human cannot synthesize and it must be intaked from food. (1)antioxidants in the food can protect food from oxidative damage and deterioration. (2) it has the antioxidant effect in the human body's digestive tract and prevent oxidative damage in the digestive tract. (3) after being absorped, it can play a role in other body tissues and organs. (4)It is derived from certain foods that have antioxidant effect of extract and can be used as a treatment drug. Antioxidant mechanism includs chelated metal ion, scavenging free radicals, quenching singlet oxygen and removal of oxygen and inhibit oxidase activity, etc
- Q:Manganese steel belongs to refractories
- Material wear and other harsh working conditions, extrusion, there will be work-hardening phenomenon rapidly on the surface. The most important feature of manganese steel is that it is not refractory under a strong impact, and under extrusion conditions, part of it will be fractured. The main form of damage is wear and consumption: It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃, mainly used to endure impact. Manganese steel is a kind of high strength steel, which is free of deformation, so that it can remain austenite good toughness and ductility at heart while keeping good wear resistance at the same time on hardened layer. Refractories are
- Q:Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.
- Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.
- Q:What are Grade-A waterproof inorganic thermal insulation materials?
- 1. Foam ceramic insulation board Foam ceramic insulation board is made of inorganic ceramic material by high temperature baking and is called ceramic insulation plate for short. 2. Composite cement foaming insulation board With cement, fly-ash and micro-silica, composite cement foaming insulation board is a kind of hole-closed lightweight hydrophobic insulation board made by foaming, maintenance,cuttign and processing. 3. Aerated concrete panel Using lightweight material, silicious material and foaming agent and so on, aerated concrete panel is a lightweight concrete panel made by high pressure steaming. 4. Rock wool board With natural igneous rock as material and thermosetting resin as binder, rock wool board is a panel made by melting in high temperature through centrifugation. I hope it can help you.
- Q:Where is the sizing nozzle for refractories? Just enter the line, master into!
- Refractories in this industry, Luoyang Hua Heng is the first to bear, and their services are thoughtful, and the quality is still very good!Wish you success！
- Q:What is the use of refractory?
- Some is insulated for personnel safety, some is to save heat loss and conserve energy, and some is used as lining of kilns. Because of its light weight, I recommand it to you and I am engeged in ceramic fiber, just an advertisement.
- Q:I wanna ask about the thermal insulation material fire resistant level?
- 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials.
