Description
Technical field
The present invention relates to high-temperature-resistant coating for metal field, particularly, relate to a kind of high temp. protective coating for titanium, and the application that should produce at titanium ingot for the high temp. protective coating of titanium, and a kind of production method of titanium ingot.
Background technology
Titanium ingot is generally wanted annealed processing in process of production, annealing generally will be carried out under the high temperature of 900 ℃ of left and right, and at high temperature, oxygen can enter titanium ingot surface, forming hard dissolved oxygen layer, will there is the deep torn grain of degree of depth 20mm left and right at 900 ℃ of heating 4h with upper surface in titanium ingot.For guaranteeing the follow-up rolling of titanium pipe and the surface quality of hot rolling titanium plate, in the operation of rolling, need titanium ingot to cut and grinding process, to remove crackle and dissolved oxygen layer, loss is larger like this.Because titanium ingot is to be made by titanium sponge reaction, cracking part and the dissolved oxygen layer of titanium ingot in heat-processed are removed, have a strong impact on cost and the lumber recovery of titanium material, therefore need to carry out high temperature protection to titanium ingot.
Titanium ingot is carried out to high temperature protection, according to the study titanium surface platinum ion electroplate can protect titanium 650 ℃ not oxidized, but can not meet the high temperature requirement of annealing far away; The MCrAlY alloy with outstanding oxidation-resistance by spray or evaporation coating to titanium matrix, but this also exist form with titanium that congruent melting compound increases and titanium production heat-processed in the formation problem of phase diffusion layer; When traditional anti-oxidation protection Paint Boron silicate glass base coating applies to titanium, the formation of oxide compound is had certain effect, but can not reach the object that prevents that dissolved oxygen layer from forming.Current useful aluminium, as the aluminium base oxidation protection coating of oxidation inhibitor, for titanium, the formation of oxide compound and dissolved oxygen layer is had certain effect, but effect is still undesirable, and because viscosity is lower, during use, can only be sprayed, and can not brush, and has limited its application.
Therefore, need to a kind ofly can effectively prevent that titanium ingot surface dissolved oxygen layer and crackle from forming, thereby greatly reduce the high temp. protective coating of titanium ingot production cost.
Summary of the invention
The object of the invention is in order to overcome existing high temp. protective coating to the dissatisfactory defect of the protection of titanium ingot, a kind of new high temp. protective coating for titanium and the production method of application and titanium ingot thereof are provided.
The present inventor finds under study for action, contain Al powder, Fe powder and Cu powder are as oxidation protection agent, and Al powder, the weight ratio of Fe powder and Cu powder is 1:0.01-0.1:0.01-0.1, the high temp. protective coating for titanium obtaining after the raw mixture that contains this oxidation protection agent and oiliness membrane-forming agent mixes, can guarantee titanium ingot not oxidized cracking in constant temperature 8h surface under 1000 ℃ of high temperature, and can greatly reduce the formation of dissolved oxygen layer, can effectively reduce production costs and improve productivity effect, and should can adopt pneumatic spraying for the high temp. protective coating of titanium, 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 high temp. protective coating for titanium, the described high temp. protective coating for titanium obtains after being mixed by a kind of raw mixture, and described raw mixture contains oxidation protection agent and oiliness membrane-forming agent; Described oxidation protection agent contains Al powder, Fe powder and Cu powder, and the weight ratio of Al powder, Fe powder and Cu powder is 1:0.01-0.1:0.01-0.1.
Preferably, the weight ratio of Al powder, Fe powder and Cu powder is 1:0.05-0.07:0.05-0.07.
Second aspect, the invention provides the application that the high temp. protective coating for titanium as above is produced at titanium ingot.
The third aspect; the invention provides a kind of production method of titanium ingot; described method is included in titanium ingot carries out before anneal, is used for the high temp. protective coating of titanium in the surface-coated of titanium ingot, and the described high temp. protective coating for titanium is the high temp. protective coating for titanium as above.
High temp. protective coating for titanium of the present invention, can guarantee titanium ingot not oxidized cracking in constant temperature 8h surface under 1000 ℃ of high temperature, and can greatly reduce the formation of dissolved oxygen layer, can effectively reduce production costs, and improves lumber recovery and the production efficiency of titanium material.For example, take and climb steel as example, rolling titanium section product, 10,000 tons of production capacities are produced in design per year, with 7.5 tons of calculating of each titanium ingot (semifinished product), will produce every year the titanium billet of 1300 left and right, and each titanium ingot is of a size of: thickness 0.28m, length 7.5m, width 1.25m; Each titanium ingot gross area is about 25m
2, the annual 32500m that approximately produces
2, the coat-thickness of the high temp. protective coating for titanium of the present invention is 0.2-0.4mm; Every square meter is approximately used 200-400g, annual approximately 6.5 tons-13 tons of the coating that use of accumulative total.With each titanium ingot, there is zone of oxidation cracking 20mm depth calculation; each titanium ingot will machine away 100-200 kilogram; with 80000 yuan/ton of calculating of titanium ingot; each titanium ingot, because oxidation cutting tip is lost between 8000-16000 unit, meanwhile, also will spend a large amount of human and material resources and cut; extra increase production cost and production time; and adopt the high temp. protective coating for titanium of the present invention, the price of coating to calculate by 200 yuan/Kg, will save every year approximately 13,650,000 yuan of production costs.
