Description
Technical Field
The invention relates to the field of production equipment of inorganic non-metallic material sliding plates used for converters and steel ladles in the metal smelting industry, in particular to a double-hole double-surface continuous sliding plate.
Technical Field
The sliding plate is a functional fire-resistant material for continuous casting, and is widely used in electric furnaces, converters, steel ladles for external refining and the like and continuous casting tundish sliding nozzle systems. The problem of short service life of the sliding plate is that besides the selection of the material of the sliding plate, the appearance design structure of the sliding plate is also important. At present, the brick type commonly adopted by the sliding plate is a sliding plate used on one side, such as a novel converter sliding plate brick (patent number: CN 207091459U) and a combined sliding plate brick for slag stopping and steel tapping of the converter sliding plate (patent number: CN 201821097120.8). The sliding plate is used as a switch for controlling the flow and the flow rate of molten steel, is arranged at the bottom of a steel ladle and a tundish, is used for bearing the chemical erosion of high-temperature molten steel at about 1600 ℃ and the pressure of dozens of tons of molten steel or even hundreds of tons of molten steel, and generates relative sliding displacement between the upper sliding plate and the lower sliding plate. The sliding plate slides by a sliding surface, the sliding frequency is limited, and the service life of the sliding plate is limited. The service life of the aluminum zirconium carbon sliding plate is improved by only depending on technical improvement, and the limit value exists, so that the service life maximization and the resource utilization maximum efficiency of the sliding plate cannot be achieved after the single-side multi-furnace continuous sliding is pursued. In addition, the sliding surface of the sliding plate with one side sliding continuously is corroded when the sliding plate is used, and the influence on the sliding back surface is small, so that the production cost of the sliding plate production factory is reduced by adopting a composite sliding plate mode, namely, a high-quality material is used on the sliding working surface, a low-quality material is used on the non-sliding non-working surface, the cost is reduced on the surface, and the effect of using the sliding plate to the full extent is achieved. In fact, the design of the composite sliding plate also brings a side effect, and the composite layer can generate thermal stress when the sliding plate is heated and cooled due to the mismatching of the material performance, so that the sliding plate is deformed and even cracks are generated. However, when all the materials are high-quality materials, the materials are large and small for the non-sliding working surface, and resource waste is caused. Therefore, the double-sided multi-furnace continuous-sliding plate provided by the invention is made of high-quality materials, and when the sliding plate is heated and cooled, no thermal stress is generated due to homogenization of the materials, so that the deformation of thermal stress cracks and temperature change of the materials can be effectively overcome. Meanwhile, the two sides are sliding working faces, and resource waste caused by large materials and small materials is avoided. The sliding times of the sliding plate are increased by times by double-sided continuous sliding, and the service life is prolonged.
The patent CN 208178409 discloses a "double-sided slide brick", which is designed such that two slides are connected into a whole by a connecting member, and after one side is worn, the brick body is turned over and then the unworn side is used. The design has two problems that firstly, the stability of the connecting piece determines the working reliability of the sliding plate, the service temperature of the sliding plate is generally above 1500 ℃, and under the high temperature, if the connecting piece is damaged due to high temperature, the joint of the double-sided bricks is loosened, and then molten steel seeps out through the brick body, so that accidents are caused. Secondly, the requirement on the size precision processing grade of the two through holes of the double-sided brick adopting the structure is very high, the production cost of the product can be increased, and the qualification rate of the product is influenced.
In order to solve the problems of low service life and low yield of the sliding plate, the invention provides a novel double-hole double-face continuous sliding plate design.
Disclosure of Invention
The invention relates to a double-hole double-face continuous sliding plate which is composed of a sliding plate main body block 1 and a screwed-in type replacement runner brick 2, wherein the side face of the sliding plate main body block 1 is respectively provided with a rectangular vertical groove 3 with a rectangular horizontal cross section and a semicircular vertical groove 4 with a semicircular horizontal cross section, a right replacement runner hole 5 is arranged in the horizontal vertical direction of the rectangular vertical groove 3, a left replacement runner hole 6 is arranged in the horizontal vertical direction of the semicircular vertical groove 4, a right-handed thread groove 7 is arranged in the right replacement runner hole 5, the left replacement runner hole 6 is arranged in the left-handed thread groove 8, and a limit bearing concave table 9 is arranged at the upper part of the thread groove;
the screwed replacement runner brick 2 is composed of a runner hole 10, a sealing anti-seepage groove 11, a screwed thread 12, a limiting bearing flange 13 and an effective displacement surface 14, wherein the runner hole 10 is arranged at the center of a circle of the cross section of the screwed runner brick 2, the radius of the runner hole 10 is R, the sealing anti-seepage groove 11 is away from the center of the circle of the cross section of the screwed runner brick 2, the radius of the edge of the sealing anti-seepage groove 11 away from the center of the circle is R, the radius range of R is less than or equal to R and less than or equal to 5R, the groove width of the sealing anti-seepage groove 11 is R/2, and the area enclosed by the edge of the sealing anti-seepage groove 11 and.
Because the sliding plate on the market is designed to be an integral structure, after the sliding plate is used for many times, even if only the area of a flow channel hole or a working plane is damaged at the damaged part, the sliding plate needs to be replaced by a new sliding plate, and the sliding plate belongs to an easily-consumed refractory material, and after the sliding frequency of the sliding plate on a ladle is only 3-10 times, the sliding plate is easily damaged and needs to be replaced. This not only causes the cost increase of iron and steel enterprises, but also causes the waste of resources. In order to solve the problems, technical personnel carry out multiple thermodynamic simulation design on the structure of the sliding plate, modularly combine the sliding working surface of the sliding plate and the runner hole, and change the original integral brick structure into an innovative design of replaceable modules. After the invention is adopted, the repeated use times of the same sliding plate can reach 2-5 times, the consumption cost is reduced by 45 percent compared with the common sliding plate, and the consumption of non-renewable refractory raw materials is greatly saved. In addition, compared with the traditional sliding plate type, the design of the brick type structure adopts the symmetrical design of the upper working surface and the lower working surface, and the design of the double-hole sliding plate eliminates the problem of brick body cracking caused by uneven pressure distribution generated by inconsistent upper and lower structures of the sliding plate when the brick body is pressed and formed, thereby effectively reducing the product reject ratio.
