The reaction equation of sulfur is as follows: The corrosion of these low melting point polymers leads to serious loss of the bonding strength of the refractory bricks, forming a new low eutectic substance without bonding strength. In the incineration process, the organic sulfur in hazardous waste undergoes high-temperature oxidation, mainly in the form of SO₃ and SO₂. Castable refractory is being poured into the door of a rotary kiln. Chlorides can aggressively attack refractory, causing excessive wear because of their corrosive nature. There are two main types of refractory: castable and brick, each with distinct advantages and disadvantages. These y-shaped anchors are similar to rebar in cement; they help give the castable lining its strength. The disadvantage to brick refractory is that it is kept in place much like a roman arch: bricks are held in place by the pressure of the other bricks pushing against each other. Its performance, design level and masonry process will affect its service life, kiln operation rate and clinker quality. T… Sodium salts have a strong ability to corrode carbon-magnesia refractories, and it is possible to increase the effect of alkalis to a higher degree at lower temperatures. refractory laning material in the rotary kiln Inlet zone The lining of rotary kilns in hazardous waste incineration requires adjusted lining concepts according to the different stressed zones. Required Products (required) As the rotary kiln rotates, that spot should read the same temperature for the entire circumference of the shell. (6) The apparent porosity should be as low as possible. In most cases, these high operating temperatures would immediately destroy an unprotected carbon steel shell. These two layers often vary in thicknesses, determined by the needs of the rotary kiln and what material is being processed. Rongsheng Kiln Refractory is the industrial refractory consultant around you. The biggest source of refractory failure is what is called cycling. By way of example, in the glass manufacturing industry furnace tanks are employed to contain baths of molten glass or of molten metal or metal salts. Many factors, such as the stress experienced by the refractory material during the operation of the cement kiln system, will affect the refractory used in rotary kiln. Required fields are marked *. Due to this potential of increased risk, this third layer is not always appropriate. Once these anchors are in place, the cement-like mixture is pumped into the lining of the rotary kiln, and allowed to cure for several days. Because of this, instead of using refractory, indirect-fired kilns typically rely on a more heat resistant shell. O. RGANISATION . The greater the probability of penetrating substances intruding into the refractory, the greater the erosion of the refractory, so the porosity needs to be controlled as low as possible. Refractory material is an important material to ensure the normal operation of cement rotary kiln. Bertandang ke game poker online The raw material granularity is 10~30mm.
