- Q: What are the reasons for the spalling of refractory bricks in the production of lime kiln?
- In the course of the production of lime kiln, the local block of refractory brick is a very dangerous signal. It is suggested that you stop the kiln to prevent the collapse of a large area. Lime kiln is the main equipment for the production of limestone kiln and rotary kiln is two, with the growth of calcium carbide lime kiln industry, iron and steel industry, the construction industry to the amount of limestone has become the main production equipment, and refractory bricks became the heart of lime kiln.
- Q: What is the price of the latest thermal insulation material?
- Also through online pre understand the products and prices, and now have large-scale manufacturers are generally opened on the cable business. Goods than three, manufacturers on-site inspection, confirm the quality of goods after considering cooperation.
- Q: What's the price of high alumina refractory bricks?
- Their refractory bricks are of good quality and low ex factory prices. Special high alumina refractory brick factory price of 1900 yuan / ton, a high alumina brick factory price of 1650 yuan / ton... This price applies to standard size, size 230*114*65mm, more products, prices go to see.
- Q: Difference between low creep high alumina brick and ordinary high alumina brick
- The emphasis is on the physical and chemical indexes of low creep and high alumina bricks. The physical and chemical indexes of the high alumina bricks are different, too. They are DRL-1550And LZ-75 perform GB GB/T2988-2012
- Q: What are the alloy wear resistance materials?
- According to the composition of Beijing Naimo metal materials company will wear resistant metal materials is divided into the following five categories: one: high manganese steel series: high manganese steel (ZGMn13),
- Q: What are the specifications for bricks?
- Thecompressive node as a new type of building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, improve work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, it has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process
- Q: What is spalling resistant high alumina brick?
- Using bauxite as main raw materials, the introduction of a small amount of ZrO2 (ZrO2 is due to phase transition, between monoclinic and tetragonal type can improve the thermal stability of the products), adding a certain amount of binder and additives, the particle size distribution control mud, forming and sintering of refractory products produced, called anti stripping high alumina brick.
- Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?
- The physical and chemical properties of refractory materials used in rotary kiln are as follows: physical and chemical properties of refractory materials used in rotary kilnMaterial name: high temperature compressive strength (MPa), softening temperature (DEG C), thermal shock resistance (1100 DEG C, cold water), sub volume density (g/cm3)Magnesia spinel brick is greater than or equal to 50 is greater than or equal to 1700 = 12 = 2.95High alumina brick is greater than or equal to 75 = 1520 = 8 = 2.57High aluminum bricks more than 50 = 1700 = 12 = 1The clay brick is greater than or equal to 30 = 1400 = 12 = 2.30
- Q: What are the categories of bricks?
- Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.
- Q: What should be used as binder for making high alumina bricks?
- Bond for making high alumina brick: soft clay has good plasticity, so the high alumina brick is usually made of soft clay as bond. However, the free Al2O3 free SiO2 and bauxite clinker clay in under 1200 degrees occurred two times of Mullization reaction, generate large volume expansion, silicon porosity, strength reduction. Therefore, the amount of clay powder in the ingredient should be no more than 5%.
