Description

Technical Field

[0001] The utility model relates to the technical field of casting machines for continuous production in the ferroalloy industry, in particular to a one-time forming alloy casting machine. Background Art

[0002] Ferroalloys are mainly used as alloy additives or deoxidizers in steelmaking to improve certain properties of steel. The traditional process of the ferroalloy industry is to pour high-temperature molten alloy iron into a pit, and then crush it manually or mechanically after cooling. The finished product particle size is between 10 and 70 mm in diameter. However, this process has high crushing costs, high labor intensity for workers, high powder rate and serious environmental pollution, which has seriously affected the development of the ferroalloy industry.

[0003] Conventional iron casting machines mainly produce blast furnace pig iron. The number of iron blocks in a single mold is between 2 and 6. The size of a single block is about 250×180×95 (mm), and the weight of a single block is 6 to 30 kg. The iron block is large in size and the product cannot meet the needs of the ferroalloy industry. First of all, it is necessary to improve the structure of the anti-splash long-life granular casting mold. After the improvement, due to the small particle diameter, the diameter is less than 70mm, the curvature of the mold cavity is also small, and the density of some alloy materials is small, resulting in low quality, which makes it difficult to demold the ingot. This is also the technical bottleneck that has not been promoted in ferroalloy casting machines at home and abroad. Secondly, alloy molten iron such as high-carbon ferrochrome and high-carbon ferromanganese has high viscosity and poor fluidity. During casting, the molten iron is easy to stick in the flow channel, resulting in a low molten iron recovery rate, difficulty for workers to clean, and increased costs due to re-smelting; due to poor fluidity, it is difficult to fill the alloy molten iron in multiple mold cavities, resulting in uneven casting of the mold cavities; secondly, the manual mode used in conventional casting can no longer meet the requirements of molten iron flow, and the uniformity of the iron block particle size also requires the control of the molten iron flow to ensure that the molten iron flow is stable and the molten iron can flow evenly into the mold cavity at each position; finally, the conventional spraying structure is suitable for large mold cavity structure, and the slurry hanging effect of multi-porous small mold cavity is poor, and the slurry hanging layer cannot play the role of isolating high-temperature molten iron, resulting in poor demoulding effect and premature damage to the anti-splash long-life granular casting mold.

[0004] There is also a flat-plate alloy casting machine on the market. After casting, it cools into a thin plate in the mold cavity with a thickness of 50 to 100 mm. It breaks into pieces by its own weight when falling. The product particle size is uneven, and more than 50% of it cannot be broken. It needs to be screened and broken again, and the powder rate is high.

[0005] The above technical problems have seriously affected the automated production of ferroalloys. There is an urgent need to develop a one-time alloy casting machine that can directly cast high-temperature molten alloy iron into a continuous production equipment with the particle size required by customers, without the need for subsequent crushing. This can reduce the labor intensity of workers, improve work efficiency, and completely solve the problems of high powder rate, difficulty in hiring, and serious environmental pollution.

[0038] The working process of the utility model is:

[0039] like Figure 1 , 2, 7 and 8: when the ladle 1 filled with alloy iron is placed on the hydraulic ladle tipping machine 2, and the casting machine is ready for production, the locking block 2b is started to lock the ladle 1 and the tipping bracket 2a through the locking cylinder action, and then the hydraulic controller 2d drives the tipping bracket 2a and the ladle 1 to rotate at a certain speed around the upper pin shaft of the fixed long base 2f, and the alloy iron flows out at a uniform flow rate through the wide overflow type iron flow trough 3 into the anti-splashing long-life granular casting mold 9; the anti-splashing long-life granular casting mold 9 filled with alloy iron is moved upward along with the chain belt 10 under the action of the transmission device 4.
