Abstract
The invention discloses a titanium roll tape cover annealing method. In the method, a combined vacuuming, argon displacement and protection mode is adopted. The method is operated by the following steps of: (1) opening a vacuuming valve (2) and starting a vacuum pump (1) to discharge gas in an inner cover (6) from a vacuuming pipe (3); stopping the vacuum pump (1) and closing the vacuuming valve (2), and opening a protective gas inlet valve (4) to feed protective gas into the inner cover from a gas inlet pipe (5); and circulating the process so as to guarantee that the purity of atmosphere in the inner cover quickly and efficiently reaches an annealing requirement of a titanium roll (7). The method has the advantages and effects that: the replacement effect can be improved, and the titanium roll tape annealing quality can be improved; the time for replacing air can also be shortened, and the production efficiency of titanium roll annealing is increased; and the amount of argon replacement can also be reduced, and the argon cost can be saved. The aims of high efficiency, energy conservation and high quality are fulfilled.
Description
Technical field
The present invention is a kind of for satisfying the novel process that the production requirement of titanium volume is taked, and combines vacuum annealing and argon shield to anneal and the method for annealing and the device of employing, belongs to titanium winding annealed producing and manufacturing technique and apparatus structure technical field.
Background technology
What the annealing of titanium winding was at present adopted is vacuum annealing process, does not see the mode of titanium winding annealing employing argon shield as yet.In conjunction with vacuum annealing and argon shield annealed advantage, before the air in the argon replaces inner cover and in the replacement process atmosphere in the inner cover is vacuumized, promptly can improve replacement result, improve titanium winding annealing quality; Can shorten the time of displaced air again, improve titanium volume annealed production efficiency; Can also reduce the quantity of argon replaces, practice thrift the argon gas cost.Reach efficient, energy-conservation, fine purpose.
Summary of the invention
The object of the invention provides a kind of annealing quality that can guarantee for the defective that overcomes above-mentioned prior art existence just; Can shorten the time of displaced air again, enhance productivity; Reduce the quantity of argon replaces, practice thrift the titanium winding bell-type annealing method of argon gas cost,, before the air in the argon replaces inner cover and in the replacement process atmosphere in the inner cover is carried out the evacuation process process in conjunction with vacuum annealing and argon shield annealed advantage.
The objective of the invention is to realize through following technical scheme.
A kind of titanium winding bell-type annealing method, the present invention adopts and vacuumizes the mode that combines with argon replaces, protection, is operating as: open vacuum pumping valve, start vacuum pump, the gas in the inner cover is discharged from vacuum-pumping tube; Stop vacuum pump, close vacuum pumping valve, open the shielding gas intake valve, make shielding gas from inlet pipe, get in the inner cover; This process that circulates, thus make atmosphere purity in the inner cover rapidly and efficiently reach the annealing requirement of titanium volume.
One side is provided with end connection inner cover in the inner cover bottom in the present invention, and the other end connects the vacuum-pumping tube of vacuum pump, and vacuum-pumping tube is provided with vacuum pumping valve; Opposite side is provided with and connects the shielding gas intake ducting in the inner cover bottom, connects the shielding gas intake ducting and is provided with the shielding gas intake valve.
Advantage of the present invention and effect are promptly can improve replacement result, raising titanium winding annealing quality; Can shorten the time of displaced air again, improve titanium volume annealed production efficiency; Can also reduce the quantity of argon replaces, practice thrift the argon gas cost.Reach efficient, energy-conservation, fine purpose.
Further set forth content of the present invention below in conjunction with accompanying drawing and embodiment.
Description of drawings
Fig. 1 is apparatus of the present invention structural representation.
Embodiment
