Description
Technical field
The present invention relates to high-temperature-resistant coating for metal field, particularly, relate to a kind of aqueous protective coating, and the application of this aqueous protective coating in titanium ingot is produced, and a kind of production method of titanium ingot.
Background technology
Titanium ingot generally wants annealed process in process of production, annealing generally will be carried out under the high temperature of about 900 DEG C, and at high temperature, oxygen can enter titanium ingot surface, forming hard dissolved oxygen layer, will there is the deep torn grain of about degree of depth 20mm in titanium ingot with upper surface at 900 DEG C of heating 4h.For the follow-up rolling of guarantee titanium pipe and the surface quality of hot rolling titanium plate, need to cut and grinding process titanium ingot in the operation of rolling, to remove crackle and dissolved oxygen layer, loss is larger like this.Because titanium ingot reacts obtained by titanium sponge, the cracking part of titanium ingot in heat-processed and dissolved oxygen layer are removed, has a strong impact on cost and the lumber recovery of titanium material, therefore need to carry out high temperature protection to titanium ingot.
Carry out high temperature protection to titanium ingot, the platinum ion plating of titanium surface can protect titanium not oxidized at 650 DEG C according to the study, but can not meet the high temperature requirement of annealing far away; The MCrAlY alloy with outstanding oxidation-resistance by spray or evaporation coating on Titanium base, but this also exists and to form congruent melting compound with titanium and increase and the formation problem of phase diffusion layer in titanium production heat-processed; When traditional anti-oxidation protection Paint Boron silicate glass base coating applies to titanium, the formation of oxide compound is had certain effect, but the object preventing dissolved oxygen layer from being formed can not be reached.Current useful aluminium, as the aluminium base oxidation protection coating of oxidation inhibitor, for titanium, have certain effect, but effect is still undesirable to the formation of oxide compound and dissolved oxygen layer, and due to viscosity lower, can only spray during use, can not brush, limit its application.
Therefore, need one can effectively prevent titanium ingot surface dissolved oxygen layer and crackle from being formed, thus greatly reduce the aqueous protective coating of titanium ingot production cost.
Summary of the invention
The object of the invention is to overcome the dissatisfactory defect of the protection of existing aqueous protective coating to titanium ingot, the production method of a kind of new aqueous protective coating and application and titanium ingot is provided.
The present inventor finds under study for action, containing Al powder, Sn powder and Cu powder are as oxidation protection agent, and Al powder, the weight ratio of Sn powder and Cu powder is 1:0.01-0.1:0.01-0.1, the aqueous protective coating obtained after raw mixture containing this oxidation protection agent and water-soluble film forming agent and water mixes, titanium ingot not oxidized cracking in constant temperature 8h surface under 1000 DEG C of high temperature can be ensured, and greatly can reduce the formation of dissolved oxygen layer, effectively can reduce production cost and improve productivity effect, and this aqueous protective coating can adopt pneumatic spraying, vacuum spraying, the multiple coating methods such as brushing, easy to use.
Therefore, to achieve these goals, on the one hand, the invention provides a kind of aqueous protective coating, described aqueous protective coating obtains after being mixed by a kind of raw mixture, and described raw mixture contains oxidation protection agent, water-soluble film forming agent and water; Described oxidation protection agent contains Al powder, Sn powder and Cu powder, and the weight ratio of Al powder, Sn powder and Cu powder is 1:0.01-0.1:0.01-0.1.
