Hard alloy forming agent capable of being rapidly dried and material mixing process thereof

Abstract

The invention discloses a hard alloy forming agent capable of being rapidly dried and a material mixing process thereof. The hard alloy forming agent is composed of, by weight, 50%-60% of paraffin, 1%-5% of oleylamine, 5%-10% of soybean oil and the balance normal octane. According to the hard alloy forming agent capable of being rapidly dried and the material mixing process thereof, a soybean oil lubricant component is introduced, an extrusion feeding material are endowed with good plasticity and good viscidity by reasonably controlling the ratio of a plasticizing component to a solvent component, and the effect that an extruded rod blank has good shape keeping performance is ensured; the solvent normal octane is introduced, compared with an existing solvent, the normal octane has good intersolubility to a forming agent of a paraffin system, and after mixing and smelting are conducted, the forming agent segregation phenomenon cannot occur; and meanwhile, the volatility of the normal octane is moderate, the stability of material mixing is ensured, and the hard alloy forming agent can be rapidly dried in the shade or dried.

Description

technical field [0001] The invention relates to the technical field of hard alloy processing, in particular to a hard alloy forming agent capable of rapid drying and a mixing process thereof. Background technique [0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which basically remain unchanged even at a temperature of 500°C , It still has high hardness at 1000 °C. Cemented carbide is widely used as tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used for cutting Difficult-to-machine materials such as stain...

AI Technical Summary

Problems solved by technology

In the process of processing cemented carbide into a tool, it needs to be extruded with a forming agent. The current extrusion material mainly controls the extrusion pressure by adding an auxiliary solvent, but adding too much solvent will increase the viscosity, and the shape after forming Poor retention; the solubility of solvent and plasticizing components in the existing molding agent system is not good, and segregation is prone to occur, resulting in unstable product quality; at the same time, organic solvents with low volatility remain in the extruded billet of the existing extrusion molding agent process , the drying time is long, the drying method is prone to cracks, the molding agent has poor volatility, and the molding agent is easy to stagnate on the surface of the product, which is not conducive to drying in the shade or drying
