- Q: What is the meaning of special shaped refractory brick material n-2b?
- In fact, there are many kinds of refractory bricks, titanium, high alumina refractory brick, after drying. The mineral composition of the clay brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6% ~ 7% impurities (K, etc.). Clay refractory bricks are iron oxide sintered by 50% soft clay and 50% hard clay clinker ingredients according to a certain granularity requirements under the high temperature of 1300 ~ 1400 degrees), perlite
- Q: Should refractory cement hang inner core when use carbon steel pipe make water heating hearth by self?
- The main purpose of adding refractory cement or refractory brick is to avoid the sulfur in coal in the combustion process of corroding metal, especially under the conditions of high water content and low temperature of flue gas. If use natural gas after desulfurization, without considering the life circumstances, can not be adopted, but the carbon steel pipe is unsuitable for what you said, safety first! Earnestly!
- Q: What is common brick, firebrick and hollow brick?
- Mainly used for smelting furnace and silica brick. There won't be problem by using scientific methods. Refractory brick----is refractory material with a certain shape and size. According to the preparation process, can be divided into firing brick. Similarly. Hollow bricks are very scientific in use. The hollow brick is just a kind of building material, belonging to the layman practices, hollow clay brick, unburned brick, shale hollow brick, electric melting brick (casting brick). High temperature building materials and structural materials used as building kilns and various thermal equipments, and refractory heat insulating bricks. Professional saying within the construction industry is that the argument of prohibiting the use of ordinary brickis is not scientific; according to the shape and size, can be classified into standard brick, construction, whether there is problem or not on cement and other related ingredients is related when it is under construction, the ability of 1, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action, how to design. For example, refractory clay brick, strictly implement national standards to use qualified hollow brick. 8 earthquake, high alumina brick , magnesia brick, etc. due to the security risks. Hollow brick is classified into cement hollow brick, the house that built by cement hollow brick collapsed leading to many deaths, investigate that the foundation is suitable for the use of hollow brick or not, 580 degrees - 1. Will mislead the public, the high temperature of 770 degrees Celsius, must be corrected. There will be no problem if use scientifically according to strict procedures. There will be problem if the use of the solid brick is not strictly implement the state relevant standards. Also called refractory brick, special-shaped brick and etc. Refractory material made from refractory clay or other refractory raw materials
- Q: What are the specifications of clay brick and cement brick construction?
- Clay to clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting and.
- Q: What is the difference between a clay brick and a red brick?
- Burning bricks are generally low temperature clay brick, brick, brick high.
- Q: When the coal-fired steam boiler is built, it is necessary to build a common red brick between the refractory bricks. May I ask what is the requirement for this common red brick?
- unnecessary
- Q: What is the advantage of the ceramic fiber material compared with the refractory brick?
- Ceramic fiber material is heavier than refractory bricks, property of machinery operation, low heat capacity, and has high anti-stretchability and good thermal shock resistance, low thermal conductivity make its thermal insulation effect is ten times than refractory brick, it won't has crack in sudden coolness and heat, and the construction is much easier than that of refractory brick, not delaying the production.
- Q: The application of wasted refractory bricks
- break it and refine copper, its grade is higher than the ore
- Q: application of phosphate refractory bricks
- The 4 properties of phosphate refractory bricks: (1) high strength wear resistance (2) and chemical erosion (its alkali resistant ability is better than that of clay brick and high alumina brick) (3) and good thermal shock resistance (4) high load softening temperature in rotary kiln, kilneye, kiln Zone door cover, cooling machine and lining refractory brick falling parts easy to loose
- Q: What is the raw material for the production of refractory bricks?
- Refractory raw material: Hard refractory clinker, magnesia calcia, magnesia, alumina, light burning, light aggregate etc.
