Description

Technical Field

[0001] The utility model belongs to the technical field of casting raw material mixing, and particularly relates to an automatic proportioning device for recycling precision casting waste. Background Art

[0002] The recycling and reuse of castings is mainly carried out through recycling and reproduction, that is, recycling and smelting of waste or defective castings, reproducing them with the help of advanced production processes and equipment, and reusing them in industry; mixing and smelting casting materials in proportion is the key to ensuring the quality of castings. The existing casting method adds different raw materials in batches through the melting furnace for proportioning, and the efficiency of full fusion of raw materials is slow;

[0003] After searching, a gray cast iron casting smelting material and a method for casting the casting with application number 202110933908.8 were found. First, part of the charge is melted and then part of the recarburizer is added; after adding the recarburizer, the charge is added to press the recarburizer into the molten iron without exposing it to the surface of the molten iron, so that the recarburizer is slowly decomposed and diffused as the molten iron continues to tumble in the furnace; in this way, the recarburizer and charge are added in turn, and the recarburizer is added all at once to the molten iron; the recarburizer needs to be added first after the high-sulfur and high-nitrogen calcined coke recarburizer is added, and then the low-sulfur and low-nitrogen graphitized recarburizer is added. Furthermore, after the furnace charge is added, ferrosilicon, ferromanganese and other alloy furnace charges are added according to the silicon and manganese content requirements of the molten iron, and the temperature is continued to rise, so that the recarburizer is completely dissolved and absorbed in the furnace as the molten iron rolls and the temperature rises; when the molten iron temperature rises to the refining temperature of 1525±15°C, the power is turned off, and the molten iron is allowed to stand for 10 to 15 minutes before slag sampling. Furthermore, after slag sampling, copper or chromium alloy furnace charges are accurately added according to the test results of the original molten iron composition to make it meet the molten iron casting composition requirements; raw materials can only be added in batches, and the efficiency of full fusion of raw materials is slow;

[0004] Furthermore, the application number is 201711036693.X, and a formula for high manganese gray cast iron and a smelting method thereof, wherein the metal charge comprises 30-40% ordinary scrap steel; 30%-45% recycled iron; 10-20% pig iron; 1.5-2.6% ferrosilicon; 1.5-3.5% ferromanganese and 0.8-1.2% copper, the metal charge is smelted into molten iron, and the mass percentage of each component in the molten iron is detected and adjusted; when the temperature is raised to 1420-1480°C, after the raw materials are completely liquefied, C, Mn, Si, P, S, and Cu measured according to the ratio are added, the temperature is raised to 1520°C, and the mixture is allowed to stand for 10-15 minutes; pouring: pouring the molten iron after inoculation treatment into a casting mold for pouring; it can be seen from the combined steps that the ratio can only be smelted in batches in a smelting furnace, and the efficiency of full fusion of the raw materials is slow.

[0005] After analyzing the above patents, it can be seen that the above smelting technical solutions can only add various raw materials in batches. Each time a raw material is added, the raw materials need to be re-fused, which leads to an increase in the smelting steps between the raw materials, a slow speed of full fusion between the raw materials, a long smelting time and low smelting efficiency.
