Wherein, K1~K4 is experimental group, and D1~D2 is control group, and a blank control group D3 is separately arranged and (does not apply coating
Direct Rolling), and wherein Watery film-fomer is epoxy resin (solid content 50%)；Curing agent is SiO2, dispersing agent is poly- second
Enol.The anti-sticking titanium coating pH value of a kind of aqueous high-temperature-resistant prepared by the present invention is 7.5~9.5；Solid content is 85~90%.
Preparation method are as follows: at normal temperatures and pressures, by Watery film-fomer, Sn powder, Fe2O3Powder, Al2O3Powder is added to container
In, it is stirred continuously in adition process, is stirring evenly and then adding into curing agent, dispersing agent and water, stirs evenly, to solution in uniformly steady
Fixed phase is to get a kind of anti-sticking titanium coating of aqueous high-temperature-resistant.
A kind of anti-sticking titanium coating of aqueous high-temperature-resistant prepared by above-mentioned each group uses pneumatic spraying, airless spraying or craft
The mode of brushing carries out after being coated in steel equipment surface, roller surface or capstan winch surface, spontaneously dries, solidifies at room temperature
10~15min obtains the film layer with a thickness of 0.2~0.4mm.Titanium tube rolling is carried out at 900 DEG C.The titanium tube table obtained after rolling
Face quality is good, and titanium tube and roll, capstan winch etc. are not adhered, and specific comparative situation is as follows:
A kind of anti-sticking titanium coating of the aqueous high-temperature-resistant of table 2 and control group test performance
From Table 2, it can be seen that using the coating coating equipment of embodiment K1~K4, the titanium tube surface matter that is obtained after rolling
Amount is good, and titanium tube and roll, capstan winch etc. hardly bond.It is not coated by the roll or strand of any coating (i.e. blank control group D3)
Disk, the titanium tube obtained after rolling, titanium tube surface defect is serious, and equipment also has a degree of viscous titanium, ability after needing to polish
It continues to use.Using the coating coating equipment of D1 and D2, the titanium tube surface defect rate after rolling is still higher, cannot prevent well
Only titanium steel bonds.
10,000 tons of production capacities are produced in design per year, are calculated with 1.5 tons of each titanium ingot (semifinished product), to be produced 6300 or so titaniums every year
There is titanium steel bonding 5mm~20mm depth calculation with each titanium ingot in billet, and each titanium ingot will machine away 100~200 kilograms, with
80000 yuan/ton of titanium ingot calculating, each titanium ingot lose between 8000~16000 yuan because gluing titanium cutting tip, meanwhile, also to spend
Take a large amount of human and material resources to be cut, it is additional to increase production cost and production time, and use this technology, will for titanium tube and
A large amount of production cost is saved in the production of other titanium alloy products, in terms of in each titanium ingot operation of rolling using 2~5kg of coating
It calculates, every coating price is calculated by 200,000/ton, and the new returns of this technology are seen below shown in formula:
The output of the annual titanium ingot of W-: being calculated with 10,000 tons, about produces 6300 titanium ingots every year；
The each titanium ingot of A- is because gluing titanium-steel layer problem cutting amount: pressing 50Kg calculating/titanium ingot；
The cost of P1- titanium ingot: 80 yuan/Kg；
W1- sprays the consumption of high temperature resistant anti-stick coating, 3Kg/ ingot；
P2- high temperature resistant anti-stick coating price per ton: it is calculated by 200 yuan/Kg；
The new returns that Y- uses this technology to generate every year:
Then:
Y=(P1 × A-W1 × P2) × W=(4000-600) × 6300=2142 (ten thousand yuan)
As it can be seen that coating provided by the invention is with good economic efficiency, social benefit and wide popularization and application foreground.
