Description

Adapter mold for continuous casting machine

Technical field:

The utility model belongs to the mold used in the alloy smelting and pouring process, in particular to a forming accepting mold for an alloy continuous casting machine.

Background technique:

In the casting machine equipment used in the metallurgical industry, the casting mold used is the most important part, because the casting mold is an important container for carrying molten steel, and the temperature of molten steel is very high. If the casting mold cannot have good corrosion resistance, high temperature resistance, etc. If there are no such characteristics, and there is no reasonable structure, it will cause problems such as short mold life and poor demoulding effect. If the mold cannot be demolded smoothly, it will reduce the working efficiency of the casting machine and even cause safety accidents. There will also be a problem of molten steel leakage, resulting in a waste of material resources. After the leaked molten steel cools, it is easy to stick adjacent molds together, which again affects the service life of the molds and increases maintenance costs.

Invention content:

Therefore, it is necessary to provide a mold with simple and reasonable structure, high temperature resistance, corrosion resistance, good strength, long-term use and smooth demoulding.

The mold for the continuous casting machine includes the mold body and the casting pits evenly distributed on the mold body; the mold body is a rectangular structure, and the front and rear upper planes of the mold body are provided with a front lap and a rear lap. The middle part of the two sides of the mold main body is equipped with fixing ears, the fixing ears are formed with fixing bolt holes, and the junction of the fixing ears and the mold main body is shaped with oblique-stayed reinforcing ribs.

Preferably, the casting pit is in the shape of a square truss, the bottom surface of the casting pit and the opening of the casting pit are both square, the bottom side of the casting pit is 15-25 mm long, and the top side of the casting pit is 70-25 mm long. 80mm, and the depth of the casting pit is 32-36mm; the square-shaped casting pit can allow the release agent to be evenly sprayed on the surface, and the casting pit under this ratio can not only meet the customer's requirements for the product, but also It can ensure better demoulding, enable the casting machine to work continuously, and improve production efficiency.

Preferably, the junction of the bottom surface and the side wall of the casting pit is rounded, and the opening of the casting pit is rounded; such a structure can make the demoulding effect better.

Preferably, the top surface of the front lap is lower than the bottom surface of the rear lap, the top of the rear lap is formed with an arc surface, and a diversion groove is also formed on the rear lap; because the mold as a whole requires a The block is fixed on the chain to work, so the rear lap part of the previous mold should be lapped on the front lap part of the next mold, and the gap is almost zero. The arc surface at the top of the rear lap part of the mold and the guide The launders can divert the molten steel poured on the rear lap to the front and rear casting pits, avoiding waste of resources while protecting the mold and reducing maintenance costs.

Preferably, the mold is made of copper-based alloy ductile iron as a whole; this material can withstand high temperatures up to 1650 degrees Celsius, prevent burning and melting when used in molten steel at high temperatures, and can also ensure the outer surface of the mold when manufacturing the mold. It is flat, so that the cast material is not easy to stick, and the demoulding efficiency is improved fundamentally.

The utility model has the following advantages: the material is cheap and easy to obtain, it can withstand high temperature, it can withstand the impact erosion of molten steel, the mold structure is simple, after the details are processed, it can be demoulded perfectly, and the demoulding rate exceeds 99%, ensuring the casting The machine can work continuously.

detailed description:

Please refer to the receiving mold for continuous casting machine as shown in Figures 1 to 5, which includes a mold body 1 and casting pits 2 evenly distributed on the mold body; the mold body is a rectangular structure, and the front and rear parts of the mold body The plane is formed with a front overlapping part 3 and a rear overlapping part 4, and the middle part of the two sides of the mold body is equipped with a fixing ear 5, and the fixing ear 5 is formed with a fixing bolt hole 6, and the joint between the fixing ear 5 and the mold body 1 is made Diagonal-stayed reinforcing rib 7 is arranged.

Preferably, the casting pit 2 is in the shape of a square truss, the bottom surface of the casting pit 2 and the opening of the casting pit 2 are square, the length of the bottom side of the casting pit 2 is 15-25 mm, and the top of the casting pit 2 is The side length is 70-80mm, and the depth of the casting pit 2 is 32-36mm; the square-shaped casting pit can allow the release agent to be evenly sprayed on its surface, and the casting pit at this ratio can not only satisfy customers The requirements for the product can also ensure better demoulding, so that the casting machine can work continuously and improve production efficiency.

Preferably, the junction of the bottom surface and the side wall of the casting pit 2 is rounded, and the opening of the casting pit 2 is rounded; such a structure can make the demoulding effect better.

Preferably, the top surface of the front lapping portion 3 is lower than the bottom surface of the rear lapping portion 4, the top of the rear lapping portion 4 is formed with an arc surface 41, and the rear lapping portion 4 is also formed with a diversion groove 42; Because the mold as a whole needs to be fixed on the chain to work piece by piece, so the rear lap of the previous mold should be lapped on the front lap of the next mold, the gap is almost zero, and the arc at the top of the rear lap of the mold Both the surface and the prepared diversion groove can divert the molten steel poured on the rear lap to the front and rear casting pits, avoiding waste of resources while protecting the mold and reducing maintenance costs.

Preferably, the mold is made of copper-based alloy ductile iron as a whole; this material can withstand high temperatures up to 1650 degrees Celsius, prevent burning and melting when used in molten steel at high temperatures, and can also ensure the outer surface of the mold when manufacturing the mold. It is flat, so that the cast material is not easy to stick, and the demoulding efficiency is improved fundamentally.

Embodiment: Install the fixed ears on the transmission chain of the continuous casting machine, and the mold bodies are next to each other one by one, and the lower plane of the rear overlapping part of the first mold body is placed on the front overlapping part of the second mold On the upper plane, by analogy, a long chain structure is formed. The molten steel is poured from the ladle into the casting pit of the main body of the mold. Because the molten steel flows continuously, it will definitely flow on the arc surface of the rear lap. The arc surface and diversion groove divert the flow into the front and rear casting pits to prevent the loss of molten steel.
