Description
Technical Field
The utility model belongs to the technical field of smelting equipment, concretely relates to masonry structure of hot metal bottle.
Background
With the improvement of the steel making process of iron and steel enterprises, the hot metal ladle is gradually combined into a hot metal ladle from two types of the prior turnover hot metal ladle and the prior transfer hot metal ladle, so that the transportation distance of the hot metal ladle is increased, the temperature of molten iron entering a converter is reduced, the energy consumption of the converter is increased, and the process runs counter to the direction of national green development of energy conservation and emission reduction.
In order to reduce the heat loss of the hot metal ladle in operation, a layer of heat insulation structure is usually added at the position of the inner side of the brick permanent layer, which is tightly attached to the hot metal ladle shell. If the heat insulation structure uses the heat insulation plate, the risk of pulverization failure exists at high temperature. After the heated board pulverization, hot metal bottle when the splendid attire molten iron, the work lining can be because of the back lacks the support, takes place to become flexible, leads to the working layer not hard up, and then causes to ooze the iron. The light heat-insulating material has a lower melting point, if the permanent layer is made of the light heat-insulating material, the heat loss of the hot-metal bottle is reduced, but the safety is extremely poor, once the hot-metal penetrates into the gap of the working lining, the permanent lining is seriously deformed, and the bag penetrating accident is further caused.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model aims at providing a masonry structure of hot metal bottle has reduced the temperature drop of molten iron, improves the heat insulating ability of hot metal bottle, has reduced the energy resource consumption of steelmaking in-process, can avoid the infiltration iron that permanent layer deformation brought to wear the package risk simultaneously again, improves the security of hot metal bottle.
In order to achieve the above object, the present invention is realized by the following technical solutions:
a masonry structure of a hot metal ladle is arranged on the inner side of a steel shell of the hot metal ladle and comprises a high-strength light brick layer, a pyrophyllite brick layer and an aluminum silicon carbide carbon brick layer which are sequentially arranged from the steel shell to the inside;
the high-strength light brick layer is provided with a layer of high-strength light bricks, the high-strength light bricks are tightly attached to a steel shell for building, the pyrophyllite brick layer is provided with one or two layers of pyrophyllite bricks, the aluminum silicon carbide carbon brick layer is provided with a layer of aluminum silicon carbide carbon bricks, two adjacent layers of bricks are constructed in a staggered joint mode, the adjacent bricks of the same layer of bricks are constructed in a staggered joint mode, and the joints of each constructed brick are filled with high-temperature cement;
the thickness of the high-strength light-weight brick layer is 32-65mm, the thickness of the pyrophyllite brick layer is 40-65mm, the total thickness of the pyrophyllite brick layer and the high-strength light-weight brick layer is 90-100mm, and the thickness of the aluminum silicon carbide carbon brick layer is 150-230 mm.
The utility model discloses in, high strength light brick can select mullite matter light brick, high aluminium matter light brick or clay matter light brick.
According to the utility model discloses, the light brick layer that excels in plays the heat preservation effect, and it has lower coefficient of heat conductivity, has certain intensity under high temperature to the shortcoming of the easy pulverization of heated board has been overcome. The pyrophyllite brick layer is a high-silica refractory material, has a high thermal expansion coefficient, can form a viscous liquid phase at the temperature of more than 1300 ℃, and once molten iron permeates, a high-silica liquid phase is formed on the contact surface of the pyrophyllite brick layer and the molten iron, so that the flowing of the molten iron can be slowed down and prevented, and the safe operation of a molten iron tank can be guaranteed. The aluminum silicon carbide carbon brick layer is a resin-bonded brick for the working layer of the hot metal ladle, which has good resistance to molten iron erosion.
In addition, the utility model discloses a masonry structure usage is not only limited to the hot metal bottle, still can be used to the similar other metallurgical container of use scene to improve its heat insulating ability and security.
The utility model discloses in still including other subassemblies that can make this hot metal bottle's masonry structure normal use, all belong to the conventional selection in this field. Additionally, the utility model discloses in add the subassembly of injecing and all adopt the conventional means in this field, for example, all can purchase as required and obtain high strength light brick, pyrophyllite brick, aluminium carborundum carbon brick, high temperature daub etc..
Compared with the prior art, the beneficial effects of the utility model include:
1. the utility model discloses a masonry structure has increased the interface of thermal current conduction through the compound application of high strength light brick and leaf wax stone brick, reduces the splendid attire molten iron in-process and scatters and disappears along the heat of package wall direction.
2. The utility model discloses utilize the volume stability of high strength light brick under high temperature, avoided nanometer reflecting plate etc. to use the shortcoming of the easy pulverization carbonization under high temperature for a long time, reduced because of the permanent layer material damage of hot metal bottle leads to ooze the risk that the package was worn to the iron.
3. The utility model discloses utilize the high viscosity characteristic of pyrophyllite brick under high temperature, reduced the risk that the package was worn to the molten iron.
