Abstract
The invention discloses a vacuum protection atmosphere annealing process of an industrial pure titanium roll, which comprises the following steps: charging a titanium roll with clean surface into a vacuum protection atmosphere annealing furnace; evacuating and heating to 430-500 DEG C and keeping the temperature for 1.5-2.5 hours; circulating in the furnace by a high-purity inert gas under the condition of micro-negative pressure; heating to 600-750 DEG C to insulate for 2-8 hours and then cooling to 400-550 DEG C; starting a forced cooling system to accelerate cooling; and discharging till the titanium roll is cooled to 170 DEG C. The mechanical performance, the chemical component and the surface quality of the annealed titanium roll can meet the requirements of a user; after the forced cooling system with a heat exchanger is adopted, the inert gas can be cooled by the heat exchanger, thereby greatly shortening the annealing period and reducing the annealing energy consumption and theproduction cost.
Description
Technical field
The invention belongs to the metal material processing technical field, specifically a kind of vacuum protection atmosphere annealing process of industrial pure titanium roll.
Background technology
Because the chemical property of titanium is active, at high temperature react with elements such as airborne O, N, H easily, form pollution layer on the surface, cause the reduction of its intensity and plasticity, hardness to increase, have a strong impact on following process and use.Therefore at present the finished products of the titanium volume full-hydrogen hood-type annealing furnace that adopts vacuum furnace more or transform original annealing coil carries out protective atmosphere thermal treatment.It is inconsistent that but the anneal of carrying out the employing vacuum oven causes titanium volume Internal and external cycle to organize easily, and the processing cycle is elongated, has increased tooling cost.If transform the full-hydrogen hood-type annealing furnace of annealing coil, adopt the annealing of argon gas or protective atmosphere displaced air, cause the air purge in the stove unclean easily, cause the titanium volume surface contamination after the annealing, foreign matter content increases.And the impurity component of titanium volume and deformation rate can influence the thermal treatment temp of titanium volume, influences final mechanical property, so must control vacuum heat treatment atmosphere, temperature and soaking time well.Too high and the overlong time of thermal treatment temp causes titanium volume bonding easily, and the uncoiling rear surface produces bonding, and surface quality can not meet the demands.
Summary of the invention
The objective of the invention is to overcome the problems referred to above that exist in the existing titanium volume annealing process, provide a kind of when high temperature the inside have the technology that rare gas element round-robin vacuum protection atmosphere annealing furnace carries out anneal, can both satisfy customer requirements with mechanical property, chemical ingredients and the surface quality that realizes the titanium volume after the annealing; And can shorten the annealing cycle greatly, reduce the annealed energy consumption, reduce cost.
Technical scheme of the present invention may further comprise the steps:
(1) the titanium package of cleaning surfaces is gone in the vacuum protection atmosphere annealing furnace, be evacuated to vacuum tightness and reach 1.0 * 10
-3Behind the Pa, be raised to 430 ~ 500 ℃, be incubated 1.5 ~ 2.5 hours with the heat-up rate of 100 ~ 200 ℃/h;
(2) with high purity inert gas pressure for-10kPa~-in stove, circulate under the little condition of negative pressure of 5kPa, and be warmed up to 600 ~ 750 ℃ by the titanium volume with the heat-up rate of 80 ~ 150 ℃/h, be incubated 2 ~ 8 hours;
(3) closing heating system, is 100 ~ 200 ℃/h by cooling rate, cools to 400-550 ℃, opens pressure cooling system and quickens cooling, comes out of the stove after being cooled to 170 ℃.
Described pressure cooling system has interchanger.
Described rare gas element is that purity is higher than 99.99% argon gas.
The present invention improves the surface quality of annealing back titanium volume, and the tissue and the performance homogeneous of titanium volume Internal and external cycle detect the rear surface and do not inhale the hydrogen phenomenon, and its mechanical property, chemical ingredients and surface quality can both satisfy customer requirements.After employing had the pressure cooling system of interchanger, rare gas element cooled off rare gas element by interchanger at circulation time, thereby took away the heat in the stove, can shorten the annealing cycle greatly, reduced the annealed energy consumption, and production cost reduces accordingly.
