Abstract
The invention relates to a processing technique of zirconium/niobium/chromium section material and belongs to the technology field of metallic material processing. The processing technique includes the following main steps: (1) material is bright-turned; (2) the material is coated with a layer of copper sheet; (3) the material is heated to the temperature of over 900 DEG C; (4) extrusion molding is carried out by an extrusion machine. The infusible materials of zirconium, niobium, chromium and so on are molded by extrusion in the extrusion machine so that the material properties are obviously improved, thereby reducing the process frequency and obviously improving the economical benefit.
Description
Technical field
The invention belongs to the machining of metal material processing technical field, particularly zirconium, niobium, chromium metal.
Background technology
The section bar material section bar of zirconium, niobium, chromium forges processing by heating the back in the past and since its metallic character in heating process with after gases such as hydrogen, oxygen in the air contacts, make the hardness raising of metal own easily, become fragile.The performance and the structure of metal itself in the power effect distortion of forging process China and foreign countries, have also been influenced.
The meeting of forging changes material property repeatedly, and the air contact causes fragility to increase
Summary of the invention
Provide a kind of section bar processing technology of zirconium niobium chromium during goal of the invention of the present invention, to overcome heating, to forge processing to zirconium, niobium, chromium effect of material performance.
Specifically, the section bar processing technology of zirconium niobium chromium, it is to implement according to following steps:
(1), stores van light;
(2), in material outsourcing one deck copper sheet protection, reduce the air contact and also play certain lubrication;
(3), be heated to more than 900 ℃;
(4), extrusion molding on extruder.
Squeeze pressure is not less than 1000 tons in the above-mentioned steps (4).
The present invention is with zirconium, niobium, chromium material, and through extruder, high warm-extrusion forming has increased tensile strength, and plasticity.Its performance significantly improves, and has reduced the processing number of times, and economic benefit obviously improves.
The specific embodiment
The section bar processing technology of zirconium niobium chromium, it is to implement according to following steps:
(1), stores van light;
(2), protect the contact of minimizing air at material outsourcing one deck copper sheet; Play certain lubrication.
(3), be heated to more than 900 ℃;
(4), extrusion molding on extruder.Squeeze pressure is not less than 1000 tons.
Claims (2)
1, the section bar processing technology of zirconium, niobium, chromium is characterized in that implementing according to following steps:
(1), stores van light;
(2), in material outsourcing one deck copper sheet protection, reduce the air contact and also play certain lubrication;
(3), be heated to more than 900 ℃;
(4), extrusion molding on extruder.
2, the section bar processing technology of zirconium according to claim 1, niobium, chromium is characterized in that squeeze pressure is not less than 1000 tons in the step (4).
