Description

Technical Field

[0001] The invention relates to the technical field of steel ingot casting, in particular to a high-temperature resistant steel ingot casting mould. Background Art

[0002] The process of pouring molten steel into an ingot mold through a steel ladle and condensing it into an ingot is also called mold casting. It is the last step in steelmaking. Qualified molten steel produced by the steelmaking furnace must be cast into ingots or billets of a certain cross-sectional shape and size before it can be plastically processed to obtain steel for various purposes.

[0003] When pouring the existing steel ingot, the molten steel needs to be poured into the casting mold first, and then it needs to be cooled and solidified. Then the staff will disassemble the mold and take out the steel ingot to complete the casting of the steel ingot. However, the casting mold of the existing steel ingot is usually used for a long time, and needs to continuously withstand the high temperature emitted by the molten steel during use. Such use will cause the casting mold to be corroded by high temperature, quickly shorten its service life, and also easily cause safety hazards;

[0004] Therefore, a high temperature resistant steel ingot casting mold is now designed to solve this type of defect. Summary of the invention

[0007] Preferably, both sides of the first inner mold close to the second inner mold are provided with rectangular slots, and both sides of the second inner mold close to the first inner mold are fixedly connected with rectangular insert plates used in conjunction with the rectangular slots.

[0008] Preferably, the rear portion of the load-bearing base frame is fixedly connected to a cylinder via a fixing seat, the top end of the cylinder is fixedly connected to an outer isolation mold via a fixing plate, and the outer isolation mold is sleeved on the surface of the first inner mold and the second inner mold of the same group.

[0009] Preferably, the upper parts of the opposite sides of the first inner mold and the second inner mold are fixedly connected with an inclined surface pressure seat through a fixing block, and the front and rear parts of the inner cavity of the outer isolation mold are provided with inclined surface inner seats used in conjunction with the inclined surface pressure seat.

[0010] Preferably, the front and rear portions of the outer isolation mold are both provided with expansion and pulling grooves, and the first inner mold and the second inner mold are both fixedly connected to the opposite sides thereof with handles for use with the expansion and pulling grooves through a fixing plate.

[0011] Preferably, both sides of the first inner mold and the second inner mold are fixedly connected with rectangular abutment plates through fixed plates, and the two rectangular abutment plates on the same side are used in combination with each other.

[0014] Beneficial Effects

[0015] The present invention provides a high temperature resistant steel ingot casting mold. Compared with the existing technology, it has the following advantages:

[0016] Beneficial effects:

[0017] (1) The high-temperature resistant steel ingot casting mold is provided with a load-bearing turntable rotatably installed on the top of the load-bearing base frame, and two groups of first inner molds and second inner molds are arranged on the top of the load-bearing turntable, which are used in conjunction with an external isolation mold. The arrangement of these structures can rotate the load-bearing turntable to switch the positions of the two groups of first inner molds and second inner molds after one group of the first inner molds and the second inner molds have completed casting, so that the first inner molds and the second inner molds that have just been subjected to high temperature can be cooled, and at the same time, another group of the first inner molds and the second inner molds can be cast. This alternating method does not affect the casting efficiency, and can also effectively solve the problem of long-term high-temperature erosion, so that the first inner molds and the second inner molds can improve high-temperature resistance and extend service life.

[0018] (2) The high-temperature resistant steel ingot casting mold is used in combination with a conical pressure seat by installing a sloped pressure seat and a rectangular abutment plate on the front and rear and both sides of the first inner mold and the second inner mold respectively. The arrangement of these structures can utilize the squeezing of the sloped inner seat on the sloped pressure seat to allow the first inner mold and the second inner mold to be tightly closed and fixed, thereby ensuring that there will be no leakage during casting. At the same time, the squeezing of the conical pressure seat on the rectangular abutment plate can separate the first inner mold and the second inner mold, thereby facilitating the staff to quickly retrieve the materials later and satisfying the current use.

[0019] (3) The high-temperature resistant steel ingot casting mold is used in combination with an L-shaped pressure plate by respectively arranging a second annular tooth plate and a first annular tooth plate inside the load-bearing base frame. The arrangement of these structures can utilize the L-shaped pressure plate to press the lifting rod to allow the second annular tooth plate to engage with the first annular tooth plate when the external isolation mold is raised or lowered, thereby locking the load-bearing turntable, thereby ensuring the overall stability of the equipment during the molten steel casting process and improving safety assurance.
