- Q: does furnace use refractory cement to make refractory bricks?
- consistence Mainly concern about the strength, generally masonry mortar does not consider the degree of fire resistance
- Q: Why is the house made of refractory bricks not warm in winter
- Heating equipment can be used
- Q: How to test the various components of the refractory brick?
- If you want to know the chemical?compound components, you can do the analysis of meteorological chromatography, and then testing, if you just want to detect contents of elements, you can do a XRF, but you should smash, grind and homogenize the refractory bricks. The specific operation process is not convenient to describe in detail, that is, X ray diffraction, through X ray fluorescence analysis, you can know that the elements and contents contained in it, if you want to understand its internal structure, you can also do a XRD
- Q: Is fireclay brick acidproof? Does clay brick anti corrosion when it's used to build chimney lining?
- Refractory bricks anti acid and alkali after high-temperature calcination, and anti-corrosion won't be a problem
- Q: How to increase the service life of high temperature refractory bricks?
- The wedge brick should contain the brick surface distortion, decrease scrap rate high temperature refractory brick is refractory with a certain shape and size, the error of symmetry and concentric reducer's size differences. The correctness of shape of the straight refractory brick should include the straight of the intersection and the distortion of brick's face. Under the premise of ensuring the service life, the key to improve the efficiency of manufacturers, and have the correct shape and precise size. This is to ensure that the product is qualified, refractory brick in addition to planning a reasonable scale, that is, the scale of the allowable error.
- Q: What are the reasons for the production of waste in the formation of fireclay bricks?
- The reasons for the production of waste when form fireclay bricks: Tile size is unqualified. This is due to the mold installation is not firm, the template transfers when molding; if the amount of material being added fluctuates largely, also can cause the body size changing. Ji Yangon Chi lie charge generation layer containing decyl poke pull and crack. The molding operation does not according to the principle of the light first and the thick later. At the initial pressure, the air doesn't releases, which causes the elastic aftereffect by repressing. Too much mud water, uneven mixture and inequal template all can make the body produce layer crack or crack. Twist. The template is used for too long, the template deforms, so raw brick deforms, the amount of water is too large, brick naturally deforms, causing the body twist. Miss edge and angle. Because of poor plasticity of mud, particles segregate, feeding back corner is not real, the body will appear side missing and angle modulation phenomenon. Bias voltage. Due to the deflection of the die head or the uneveness of mold bottom. Loose。 Due to insufficient feeding amount or insufficient pressure times.
- Q: What is the meaning of the new type of dry rotary kiln refractory brick 620,320?
- 20 stands for that the length of the brick is 20CM, there is only a kind of 620 brick for masonry. Simply say: 1. 620 and 320 these two specifications of bricks are needed simultaneously if it is 4 meters kiln that should be built. When the diameter of the kiln is 6M. Other specifications of kiln can be built by useing these two kinds of bricks in different proportions. 3M kiln can be built only by using 320 brick, its proportion of use is 16. 3 stands for kiln's diameter
- Q: Why can't gravity retaining walls be made of clay bricks?
- The masonry of gravity retaining walls, of course, takes into account compression problems, and the use of clay bricks requires consideration of compression calculations and service life.
- Q: The boiler is divided into several categories according to the structure, what characteristics does each have?
- package boiler and assemble boiler are divided into vertical boiler and horizontal boiler. Vertical boiler. Assembled boiler adapts to boiler more than 6 tons, the package adapts to boiler less than 10 tons.
