Abstract

The invention relates to a manufacturing method of a metal foil strip and a deformed wire rod. The manufacturing method is characterized in that a metal wire or bar with certain diameter is manufactured into the metal foil strip or deformed wire rod by adopting a horizontal rolling method. In the invention, the wire or bar with certain diameter is manufactured into the metal foil or deformed wire rod with required thickness and width through horizontal rolling or deformed roller rolling, restriction of a wide-size rolling mill is overcome, a minitype multi-roll high-accuracy rolling mill is adopted, the method has high yield and is simple and convenient to operate, and the produced product has stable performance and high and uniform surface finish quality.

Description

The manufacture method of a kind of metal foil band and shaped wire

Technical field

The present invention relates to technical field of nonferrous metal processing, particularly relate to the manufacture method of a kind of metal foil band and shaped wire.

Background technology

Paper tinsel band that is processed into and special-shaped wire section are widely used in fields such as electronics industry, chemical anticorrosion, high temperature heating and heat insulation, Aero-Space, medical equipment.

At present, the manufacture method of paper tinsel band mainly adopts the ingot casting cogging, is rolled into paper tinsel, the sheet material of broad, is processed into the foil of the width that needs again through sub-cut; Perhaps pass through sub-cut, strike out special-shaped wire section.The lumber recovery of this process route is low, the control of product quality difficulty is big, and product length is limited, and needs wide cut, big working ability milling train, and the precision of wide cut milling train is difficult to guarantee.

Summary of the invention

Purpose of the present invention just is to overcome the defective of above-mentioned prior art, and a kind of lumber recovery height is provided, and easy and simple to handle, product surface fineness is low, the metal foil of good evenness and the manufacture method of shaped wire.

For realizing that the technical solution used in the present invention is:

The manufacture method of a kind of metal foil band and shaped wire is characterized in that: the metal wire material or the bar that will have certain diameter are made metal foil band or shaped wire by horizontal rolling;

Described horizontal rolling is or/and on the multi-roll mill at two rollers, with hot-working or temperature processing or cold working method, use conventional plain-barreled roll or grooved roller or protruding roller, the metal bar of certain size or silk material are carried out the metal foil band of the rolling or repeat-rolling of single to needed thickness and width;

Described horizontal rolling be at two rollers or/and on the multi-roll mill, with hot-working or temperature processing or cold working method, use special-shaped pressure roller, the metal bar of certain size or silk material are carried out the special-shaped wire section of the rolling or repeat-rolling of single to definite shape;

Described metal wire material or bar are meant tantalum, niobium, tungsten, molybdenum, titanium and alloy thereof;

The diameter of described metal wire material or bar is not more than 10mm;

The sectional area of described metal foil band or shaped wire is not more than 78.5mm ²

When level is rolling, carry out annealing in process;

Described annealing in process is meant under vacuum state, is incubated 30～60 minutes under 900 ℃～1050 ℃ temperature;

Silk material or the bar that the present invention adopts certain diameter by level rolling or special-shaped rolling make the metal foil or the shaped wire of required thickness and width, overcome the restriction of wide cut milling train, adopt small-sized multiple roll high-precision rolling mill, lumber recovery height, easy and simple to handle, the properties of product of being produced are stable, surface smoothness is high and uniformity.

The specific embodiment

Embodiment 1

With the niobium silk of diameter 2mm in vacuum drying oven with 1050 ℃ of annealing, be incubated 60 minutes, take out the cooling back.

2. on six-high cluster mill, be rolled into the niobium band of 0.35x4.9mm, after the pickling, adopt the same process annealing of mentioning with (1), be rolled into the niobium band of 0.076x5.0mm again with 12 roller mills.Rolling mill practice sees Table 1:

Table 1 niobium band rolling mill practice standard

Embodiment 2

Diameter 2.0mm molybdenum filament after the continuous annealing by 900 ℃ of heating, is rolled into the molybdenum band of 0.25x3.2mm with two-roller mill, and with 900 ℃/30min vacuum annealing, with the cold rolling molybdenum foil that becomes 0.037x3.75 of 12 roller mills, technology sees Table 2 again after the pickling:

Table 2 molybdenum foil rolling mill practice

Embodiment 3

Tantalum tungsten (W content 2.5%) alloy bar of the diameter 8mm of annealed state is rolled into the tantalum-tungsten alloy band of 1.0x13.5mm with two-roller mill, after the pickling with 1350 ℃/30min vacuum annealing, again with the tantalum-tungsten alloy foil of the cold rolling one-tenth of 20 roller mills 0.08x16mm, intermediate demand increases a vacuum annealing, 1350 ℃/30min, technology sees Table 3:

Table 3 tantalum-tungsten alloy foil rolling technology

Embodiment 4

The titanium silk of the diameter 1.5mm of annealed state is rolled into the tantalum-tungsten alloy band of 1.0x13.5mm with two-roller mill, after the pickling with 1350 ℃/30min vacuum annealing, again with the tantalum-tungsten alloy foil of the cold rolling one-tenth of 20 roller mills 0.08x16mm, intermediate demand increases a vacuum annealing, 1350 ℃/30min, technology sees Table 3.
