Q:What is the high temperature limit of refractory bricks and refractory soil?
Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
Q:What's the difference between high alumina refractory bricks and high alumina refractory bricks?
The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.
Q:What's the weight of the refractory bricks?
Fireclay refractory bricks: 3.4kg-3.8kg - according to the quality of raw materials, prices ranging from 1 yuan to 2.7 yuan, high alumina refractory brick: three, high aluminum in 3.9kg or so. Ordinary T-3 firebrick weight calculation method: 230*114*65*2.2/2.1.
Q:How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
Because the hot air outlet of the top burning hot blast furnace is high, the installation requirement of the hot air manifold is high, and the requirement of the strength of the pillar structure is higher, so the rectangular arrangement of the hot blast stove is arranged. The top burning hot blast stove is located on the furnace top because of burner and hot air valve,Therefore, operation, maintenance and installation all require mechanization and automation. Also, because these water cooled valves are mounted with a high elevation,Therefore, the demand for cooling water supply pressure should be improved accordingly, the use of large top burning hot blast stove, the key lies in the design of high-power high-efficiency short flame burner. The top combustion hot blast furnace absorbs the advantages of internal combustion and external combustion hot blast stoves, and overcomes some of their shortcomings,Its structure can meet the requirements of modern blast furnace for high temperature, high pressure and large scale development,Combustion capacity, while meeting production requirements, has been successfully reduced by many devices,
Q:What materials are used for roof insulation?
The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.
Q:Are there any differences between insulating bricks and refractory bricks?
As the name suggests, the main role of insulating brick is used to preserve heat and reduce the loss of heat. Such as: Molai S; and the firebrick is mainly used to withstand flame burn. Bricks usually do not contact fire directly, while refractory bricks usually contact the flame directly.
Q:Which is better, the soft core or the hard core?
The wire has two kinds of hard core and soft core, the hard core line is only one wire core, and the soft core line has a plurality of wire cores. For the same sectional area, the 7 core is more than the more than 30 core. There is a difference in use. Generally used for DC is the use of hard core line, because of its small line consumption; and for communication, we should use soft core line, but also in order to reduce its line consumption
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:Introduction of high alumina brick
Made from alumina or other raw materials of high alumina content; formed and calcined. High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining.
Q:Which is faster for heat transfer between corundum bricks or 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.
