- Q: What materials is silicious thermal insulation board made of?
- Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
- Q: How to solve the shell, the crack problem of refractory material in the process of forming.
- Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
- Q: which kind of refractory is used in golden smelting furnace? How about his using temperature
- generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
- Q: Concrete composition and function of magnesia bond used in refractory
- According to the chemical composition and use can be divided into metallurgical magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia brick and other varieties. Its performance is greatly affected by CaO/SiO2 ratio and impurities. High purity magnesia brick refractoriness under load and thermal shock resistance are better than the general magnesia brick. High refractoriness, has good resistance to alkaline slag and iron slag, is a kind of important senior refractories. Use of magnesia product production by sintering process, sintering temperature is 1500 ~ 1800 DEG C, in addition, you can also add chemical bond, made of brick and unshaped refractory material. Mainly used in open hearth furnace, electric furnace, converter, oxidation non-ferrous metal smelting furnace, cement kiln and alkaline refractory kiln etc..
- Q: What is special refractories?
- Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
- Q: Fire resistance and evaluation of refractory for casting
- The products to be tested are broken and ground, adding organic binders (usually dextrin) that do not affect the refractoriness. Water is used to make standard sized test cones, as shown in figure 1-2-1. Test cone is positive, three edge cone, the bottom side length of 8.5mm, the top side length is 2mm.Test, the equivalent of high standard cone refractoriness of the 2 products to be high, No. 1 and No. 1 high temperature low standard cone of each one, and the 2 to be tested in accordance with regulations frustum cone plug made of high aluminum material, a cone prism and vertical 8 degrees. 1 degrees tilt angle. Then, the cone is heated in a high temperature furnace. When the test cone with a high temperature and bending down to the standard cone top contact cone, the high standard cone refractoriness refractoriness is running.
- Q: Detailed description of magnesia dolomite refractory material?
- The use of low chromium or chrome free refractories is more and more widely used, developed countries in the development of chrome free refractories to replace the chromium containing material, through research and production practice show that dolomite refractories is the refining of AOD furnace, large cement kiln ideal material.
- Q: What is the the best matching ratio of refractory cement?
- The best matching ratio of refractory cement is 30%. Refractory cement is also known as aluminate cement. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement. Aluminate cement is often yellow or brown or gray. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc. It is a special cement. I hope my answer will be helpful to you.
- Q: What are the requirements on fire resistance period of C-level fireproof glass?
- What are the requirements on fire resistance period of Class C fireproof glass? The fireproof glass is a special glass which can maintain its integrity and insulation in required fire resistance tests, it can be classified into three types: Class A the fireproof glass which meet demands of fire integrity, and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.
- Q: Who knows what fire heat preservation material are there?
- Organic material, polystyrene board, plastic extruded board, phenolic resin. Sea capacity module (fire insulation materials fire performance can reach the B1 level, thermal conductivity is only 0.028w\m - K is a good choice, class A fireproof materials now is the mainstream rock wool (mineral wool is wool). A1 fire resistance The largest manufacturer is Thai stone rock wool Co. Ltd.
