Production process
Raw material preparation and mixing(Ground Tungsten Plate)
High purity tungsten powder (purity ≥ 99.95%) is used, which is uniformly mixed with nickel, cobalt and other elements through ball milling, and the particle size is controlled at 5-10 microns to optimize formability.
Compression molding(Polished Tungsten Sheet)
Apply high pressure (≥ 2500 MPa) under isostatic pressing or compression molding to prepare the billet, ensuring that the relative density is>90% before subsequent processing.
Sintering treatment(Sintered Tungsten Plate)
High temperature sintering (1200-1300 ℃) in hydrogen or vacuum environment to improve the density and strength of the green body; Optional vertical melting or spark plasma sintering (SPS) techniques can be used to refine grain size.
Rolling forming(Forged Tungsten Plate)
divided into hot rolling (1350-1500 ℃), warm rolling (1200 ℃), and cold rolling stages; Preheat the rolling mill to 100-350 ℃ to reduce deformation resistance, and perform multiple passes of rolling to thin the sheet from 8mm to 0.2mm.
The core characteristics of tungsten plate include high hardness, high temperature resistance, and chemical stability
Physical characteristics
High hardness (HV 220-300, can be improved by cold processing), extremely high melting point (3422 ℃), high density (about 18 g/cm ³, 2.3 times that of steel), and low coefficient of expansion.
Chemical characteristics
Resistant to air corrosion at room temperature, chemically stable, and resistant to high temperature oxidation and corrosion.
Mechanical performance
Strong wear resistance and high deformation resistance, but low-temperature brittleness needs to be overcome through process optimization.
