- Q: In 2016, a few of the traditional refractory materials will be able to survive
- From the year 2015 to the year 16 the end of the year, refractories industry presents two kinds of situations: one is a small business, a single product variety and equipment, to meet the demands of both environmental protection and the downstream market, such enterprises are generally in the Qing state inventory;
- Q: What are the grades of high alumina bricks?
- High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick
- Q: What refractory material does cupola lining use?
- Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
- Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?
- 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
- Q: Which is better, the soft core or the hard core?
- The use of each of the single core copper wire with low line, 1.5 square with cap line home, socket 2.5 square, air conditioning to walk alone line 4 square can, when the terminal box into a socket with leakage protection switch, prevent overload and short circuit.
- Q: How to distinguish the good or bad of the high aluminum brick?
- The general high alumina bricks used in the steel, steelmaking, hot blast furnace, electric furnace, blast furnace, reverberatory furnace, rotary kiln lining of industrial furnace in China, mainly composed of a bauxite; sillimanite minerals (including kyanite, andalusite, sillimanite etc.); synthetic material, such as alumina synthesis of mullite, corundum, etc.. High aluminum brick has good quality, high refractoriness, long life and other characteristics, is the main use of refractory brick kiln products, commonly used units can not distinguish the quality and grade of high aluminum brick right in the procurement time, caused by the high prices to buy low grade products, thereby reducing the furnace life therefore, Zhengzhou's Sindh yuan refractory material factory in here is simple to introduce how to identify the quality when purchasing brick high alumina brick.Color: in the purchase of high alumina brick, first of all to see the color, high quality aluminum brick surface smooth, yellow color white, four sides smooth, no broken angle, no cracksWeight: the weight of a block of bricks to be called, according to the standard weight level, high aluminum brick weight of 4.5 kg. Two grade high alumina brick weighs 4.2 kg, three high aluminum brick weighs 3.9 kg, the same level, the same parameters can reach this standard can be regarded as high-quality high aluminum bricks, the opposite is not up to the weight that the quality is good, if there is a crack, four angle uneven, off angle phenomenon, then substandard products, some of the above points to help to the purchaser
- Q: Which thermal shock stability of clay brick and high alumina brick is good?
- The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.Thermal shock stability is much better than clay brick.
- Q: What is the high temperature limit of refractory bricks and refractory soil?
- According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, ordinary brick, specific rotation. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature.
- Q: What should be used as binder for making high alumina bricks?
- In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.
- Q: High alumina brick 80 with which high aluminum cement?
- Which kind should be chosen should be determined according to the conditions of use, life expectancy and cost control. By the way, the quality of masonry is also very influential.
