Description

Technical Field

[0001] The utility model relates to the field of metallurgical continuous casting, in particular to an online rotary plate table for continuous casting billets. Background Art

[0002] With the rapid development of the steel industry, users' requirements for steel quality are increasing day by day. The production of high-quality, high-tech, and high-value-added steel products has become an inevitable choice for steel companies. The quality of continuous casting billets directly affects the performance of steel. Therefore, strengthening the insulation strength and rotation efficiency of continuous casting billets is an important part of improving the quality of continuous casting billets. How to strengthen the insulation strength and rotation efficiency of continuous casting billets has long been a technical problem that has plagued the steel industry and has become a restrictive factor in smelting special steel and high-quality steel.

[0003] Continuous casting is one of the core processes that represents the highest level of current iron and steel metallurgy. It is the decisive link in the transformation of steel from liquid to solid. Its product is a continuous casting slab with a certain length and cross-sectional size. After the continuous casting slab leaves the casting machine, it is cut to size by flame cutting, and then the surface quality is inspected or cooled before entering the next process. Due to the low thermal conductivity of steel and poor thermoplasticity of steel, the thermal stress during the cooling process is relatively large; at the same time, since non-equilibrium structures such as martensite and bainite are obtained when the steel is naturally cooled, it is easy to cause large organizational stress, which is very likely to cause production accidents such as cracking and fracture of the continuous casting slab caused by stress concentration. Therefore, the cooling rate of the continuous casting slab must be reduced to improve its plasticity and toughness.

[0004] When the continuous casting billet cannot be sent directly to the steel rolling mill, the continuous casting billet is placed directly on the roller table, which affects the smooth rhythm of production and needs to be placed offline. The offline continuous casting billet is simply insulated, the insulation effect is poor, the cooling speed is fast, the internal quality of the billet is poor, and stress concentration and even cracking are prone to occur.

[0005] The existing patent CN206286522U proposes a slow cooling and heat preservation device for continuous casting slabs, which can achieve the effect of slow cooling of continuous casting slabs without using a slow cooling pit. However, the slabs of the invention cannot be rotated online, and the production efficiency is low.

[0006] The existing patent CN205839069U proposes a slow cooling and heat preservation device for alloy steel continuous casting slabs. The invention has a reasonable structure, can control the cooling rate of continuous casting slabs, can prevent the generation of white spots, improve the quality of continuous casting slabs, is simple to use, easy to move, and can reduce the labor intensity of operators. However, the invention does not explain the online rotation storage process of slabs.

[0007] The existing patent CN203495169U proposes a special insulation cover for medium-carbon medium-high alloy steel continuous casting slabs. The invention adopts a technical solution of adding insulation blocks in the insulation cover body to effectively prevent the heat loss of the continuous casting slabs, solves the problem of poor insulation effect of general insulation covers, has a simple structure and good insulation effect. It is suitable for the production of medium-carbon medium-high alloy steel. However, the invention does not explain the online rotation storage process of the slabs. Summary of the invention

[0008] The technical problem to be solved by the utility model is to provide an online rotating plate platform for continuous casting billets, so as to solve the problem of excessively rapid temperature reduction during the rotation process of the continuous casting billets.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A continuous casting billet online rotating plate table comprises a platform, a lifting support column, a base and a heat preservation cover. The lifting support column is connected to the bottom of the platform, and the lifting support column is connected to the base. The platform comprises a platform frame, and a plurality of troughs are arranged in the platform frame. A plurality of anchor claws are connected to the bottom plate of the trough, and refractory materials are filled around the anchor claws in the trough. A plurality of ball universal pulleys are connected to the upper surface of the platform frame, and one side of the platform frame is connected to the heat preservation cover through a flip mechanism, and the top surface of the heat preservation cover is covered with a radiation heat preservation board.

[0011] The lifting support columns are hydraulic lifting columns, and the lifting support columns are arranged at the four feet of the platform.

[0012] The top of the trough body is open, and the refractory material is exposed from the open portion.

[0013] The turning mechanism is a hydraulic turning frame which can turn within a range of 90°-180°.

[0014] The number of the ball universal pulleys is 15-35.

[0015] The number of anchor claws in each slot body is 10-40.

[0016] Compared with the existing technology, the beneficial effects of the utility model are:

[0017] The utility model has a simple structure and low cost. The online rotating plate platform of the continuous casting billet is placed as a whole beside the continuous casting roller. When the continuous casting billet cannot be directly sent to the steel rolling mill on the continuous casting roller, the billet is pushed onto it by a steel pusher for storage, thereby improving the billet rotation efficiency. Refractory materials are provided in the device platform, and a heat preservation cover is provided to improve the online heat preservation effect of the rotating billet. Thus, the internal quality of the billet is improved. The utility model facilitates the loading and unloading of the billet and reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
