Definitions
- the present invention relates to liners for hollow charges made of cold-pressed powder metal mixtures which are used, for example, in the field of oil and gas-conveying industry for the purpose of deep borehole blasting.
- the powder metal mixtures used to make the inserts can be varied widely.
- a blend may contain 10 to 30 weight percent of a soft metal that serves as a binder, while the remainder of the blend may be harder metals.
- a binder lead is used in most commercial deposits.
- other metals such as bismuth, silver, gold, tin, uranium, antimony, zinc, cobalt or nickel.
- the remainder of the mixture often consists of heavy metals such as copper, bronze and / or tungsten in different mixing ratios. In order to achieve greater penetration depths, it is proposed in the relevant literature to choose the density of the deposit material as high as possible.
- tungsten is particularly suitable as a material for powder-shaped hollow charge deposits, as proposed in US Pat. No. 5,656,791 A and DE 196 25 897 A1.
- the pellets from the mixture become unstable and can no longer be handled, lower tungsten fractions lead to a reduction in density.
- Object of the present invention was the provision of inserts for shaped charges, which cause a large hole diameter at the same time high penetration depth.
- the object is achieved by the features of the main claim.
- Preferred embodiments can be found in the subclaims. It was found that the addition of light metal powders, for example aluminum and / or titanium powder, to tungsten-lead mixtures or tungsten-copper / bronze-lead mixtures leads to a significant increase in the hole diameter, without causing great losses in the penetration depth .
- tantalum and / or other heavy metals and / or their alloys can also be used.
- Tungsten can also be completely replaced by bronze or copper or a mixture of these with the addition of light metal powders and higher levels of lead in the mixture. Bronze and copper can be used in any mixing ratios.
- molybdenum can also be added to these powder metal mixtures according to the invention for the production of hollow charge deposits.
- Hollow charge inserts made of powder metal mixtures, which additionally contain graphite.
- Hollow charge inserts made of powder metal mixtures containing tantalum and / or other heavy metals and / or their alloys in addition to or instead of tungsten.
- Inventive hollow charge deposits made of powder metal mixtures, prepared by cold pressing of powder metal mixtures.
- Example 1 Hollow charge insert 1 73.5% by weight bronze 19.5% by weight lead 7% by weight titanium
