Problems solved by technology

At the same time, the pouring temperature of the ferroalloy is 1650°C, and the cast iron mold with a large inner cavity made of ordinary cast steel cannot meet the actual needs and seriously affect its service life.
[0005] In addition, in the production process of casting non-metallic materials industry, the user pours the molten non-metal directly into the formed sand pit, and after cooling and solidifying, it is artificially crushed to make it into small pieces of material, which is convenient for later use , but in the crushing process, it is easy to cause small and irregularly shaped materials, which reduces the yield
[0006] However, the block size range of non-metallic materials for melting and casting is required to be 30-100mm, and the pouring temperature of non-metallic materials can reach up to 2200°C. If the original cast iron mold with a large inner cavity made of ordinary cast steel is used, it cannot meet the actual needs. , also seriously affect its service life

Embodiment 1

[0049] The material of the casting mold is to add 1.00% chromium (Cr) and 0.30% molybdenum (Mo) of the total mass to ZG270-500 cast steel to form a low-alloy steel of ZG35CrMo material, which improves the high temperature performance of the casting mold and improves its creep resistance ability to change. The mass percentages of raw materials in ZG270-500 cast steel are as follows: C 0.30~0.37%, Si 0.20~0.90%, Mn 0.50~1.00%, P≤0.030%, S≤0.030%, and the rest is iron. The structure of the casting mold is simulated and analyzed by the temperature field. The wall thickness is 45mm. The top dimension of the mold cavity is designed to be a×b, and the bottom is spherical. The actual embodiment is to design the size of the molding cavity according to the size of the alloy material forming block "top width x bottom diameter x height = 80 x SR26 x 55mm, the sky is square and the earth is round", the bottom diameter SR is a hemispherical structure of 25mm, and the longitudinal outer wall...

Embodiment 2

[0051] The material of the casting mold is to add 1.75% nickel (Ni), 1.00% chromium (Cr) and 0.30% molybdenum (Mo) to ZG230-450 to form ZG25NiCrMo low-alloy steel to improve casting fluidity. Improve the strength of steel and improve its toughness; improve the high temperature performance of the casting mold and improve its creep resistance. The mass percentages of raw materials in ZG230-450 cast steel are as follows: C 0.22~0.30%, Si 0.20~0.90%, Mn 0.50~1.00%, P≤0.030%, S≤0.030%, and the rest is iron.

[0052] The structure of the casting mold is simulated and analyzed by the temperature field. The wall thickness is 55mm. The top dimension of the mold cavity is designed to be a×b, and the bottom is spherical. The actual embodiment is designed for the size of the forming block of non-metallic material "top width x bottom diameter x height = 80 x SR28 x 55mm, the sky is square and the earth is round". The size of the molding cavity is designed. The radius of the arc R is 55. ...

Description

technical field [0001] The invention relates to a casting machine for casting special materials. Background technique [0002] In the production process of smelting alloy molten iron, some users in the market use existing cast iron equipment to continuously pour the smelted high-temperature alloy molten iron into iron blocks, and some users directly pour the smelted alloy molten iron into the formed sand pit. After cooling and solidifying, manual crushing is used to turn it into small iron nuggets, which is beneficial for steelmaking. However, in the crushing process, it is easy to cause small and irregular iron nuggets, which reduces the yield. [0003] However, the cast iron molds used in the existing cast iron machines cast alloy iron blocks or non-metallic materials that are larger in size, and the overall size of a single block is about 250×180×95 (mm). For an alloy iron block, the weight of a single block is about It is 17kg. The cavity of the cast iron mold is singl...
