Abstract
The invention discloses an annealing process of a titanium plate. The annealing process comprises the following steps: putting the titanium plate into an annealing furnace, and performing vacuum-pumping till the vacuum degree reaches 10<-4> Pa; heating the titanium plate to a temperature in a range of 600-650 DEG C after the vacuum-pumping, and performing heat preservation for 5-6 h, wherein the heating speed is in a range of 15-17 DEG C/h; eliminating the air, and replacing the air with argon during the air elimination process; evenly lowering the temperature to a range of 120-150 DEG C by using a blower fan for forced circulation; and taking the titanium plate out and performing cooling at a cooling speed of 5 DEG C/h. The annealing process is carried out at a vacuum condition with a vacuum degree of 10<-4> Pa, and argon is used as the protection gas during the annealing process, so that oxidation of a titanium strip coil is effectively prevented during the annealing process.
Description
Technical field
The invention belongs to titanium plate processing technology field, be specifically related to a kind of annealing process of titanium plate.
Background technology
Titanium relies on light specific gravity, high/low temperature intensity is good, solidity to corrosion is good, have superconduction, store the excellent performance such as hydrogen, memory, be widely used, but titanium is relatively more active, even if at high temperature also can be oxidized under trace oxygen environment, therefore very easily reacts with nitrogen, hydrogen, oxygen in annealing process.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, provide a kind of annealing process of titanium plate, method is simple, effectively avoids oxidation.
The annealing process of titanium plate provided by the invention, comprises the following steps: titanium plate is put into annealing furnace by (1), is evacuated to vacuum tightness 10-4Pa; (2) vacuumize post-heating to 600-650 DEG C, insulation 5-6h, rate of heating is 15-17 DEG C/h; (3) excluding air, by argon replaces in the process that air is got rid of, and carry out pump circulation by blower fan, make homogeneous temperature be cooled to 120-150 DEG C, take out titanium plate, speed of cooling is 5 DEG C/h.
The annealing process of titanium plate provided by the invention, its beneficial effect is, is to anneal under the vacuum condition of 10-4Pa in vacuum tightness, and is shielding gas with argon gas in the process of annealing, effectively prevents titanium strip coil to be oxidized in annealing process.
Embodiment
Below in conjunction with an embodiment, the annealing process of titanium plate provided by the invention is described in detail.
Embodiment
