Description
Technical field
The present invention relates to paint fields, and in particular, to a kind of oiliness protective coating composition, the coating composition is in titanium
The production method of application and titanium tube in pipe production.
Background technique
At present using the prior art during producing titanium tube, after titanium ingot is kept the temperature 4h in 900 DEG C of heating furnaces, release
Heating furnace carries out rolling titanium tube work.Since titanium-based titanium alloy is after 900 DEG C of heat preservation 4h of high temperature, when rolling titanium tube, meeting and steel
" viscous titanium " occurs for iron rolling equipment, roller-way and rolling capstan winch, this makes rolling titanium tube surface " lacking for different depth occur
Meat " phenomenon, due to being rotation perforation, rolling when rolling titanium tube, titanium base is progress drilling/rolling during high-speed rotation,
Since the hot properties of titanium-based titanium alloy acts on, it is easy to be deposited with phenomenon with iron, produces TiFe phase what is more.If
Titanium tube Surface Creation TiFe, which meets, seriously affects titanium surface mechanical properties and tissue, makes titanium tube in following process and use process
In bring various defects, loss, it is not corrosion-resistant the defects of problem；In addition, since equipment " viscous titanium " causes to roll subsequent
Want first grinding apparatus that could roll subsequent titanium tube again in journey.It is unable to continuous rolling titanium tube or titanium product, when wasting a large amount of
Between and energy consumption；Meanwhile dimension of inner and outer diameters precision and surface quality to guarantee titanium tube, manufacturer is all to have titanium tube surface
The part of " misrun " phenomenon carries out machining, lose in this way it is larger, since titanium ingot is to be reacted to make by titanium sponge, by titanium tube
Inner and outer portions machine away, and seriously affect the cost and lumber recovery of titanium.
Therefore, it is necessary to one kind can effectively prevent titanium-steel bonding, to greatly reduce titanium tube production cost, improve production effect
The coating of rate.
Summary of the invention
The purpose of the present invention is overcoming the phenomenon that production titanium tube is easy to happen titanium-steel bonding in the process in the prior art, mention
For a kind of oiliness protective coating composition and its application and the production method of titanium tube.

The total weight of coating composition is 100 parts by weight meters, the oiliness protective coating composition contain the oiliness of 5-15 parts by weight at
Film, the Al powder of 40-45 parts by weight, the Sn powder of 0-5 parts by weight and 40-45 parts by weight Al2O3Powder.
The present invention also provides application of the oiliness protective coating composition of the present invention in titanium tube production.
The present invention also provides a kind of production methods of titanium tube, wherein this method, which is included in, carries out rolling titanium tube for titanium ingot
Before, oiliness protective coating composition is coated on the surface of capstan winch and/or roller-way, wherein the oiliness protective coating composition
For oiliness protective coating composition of the present invention.
Oiliness protective coating composition provided by the invention can guarantee titanium ingot 900 DEG C rolling or perforation procedure in, not with
Bonding reaction occurs for steel equipment roller-way and/or capstan winch, improves the lumber recovery and production efficiency of titanium processing.For example, to climb steel
For, titanium product is rolled, 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 every year
There is titanium steel bonding 5mm-20mm depth calculation with each titanium ingot surface in a or so titanium ingot, and each titanium ingot needs machine away
It 100-200 kilograms, is calculated with 80000 yuan/ton of titanium ingot, each titanium ingot is because " viscous titanium " phenomenon is cut partial loss in 8000-
Between 16000 yuan, meanwhile, also a large amount of human and material resources to be spent to be cut, when additional increase titanium production cost is with producing
Between, and oiliness protective coating of the present invention is used, a large amount of production will be saved for the production of titanium tube and other titanium alloy products
Cost, to use coating 2-5kg to calculate in each titanium ingot operation of rolling, coating price is calculated by 200,000/ton, will save give birth to every year
Produce about 21,420,000 yuan of cost.
Oiliness protective coating composition of the present invention is applied in titanium tube production, it is simple production process, easy to operate, it can
To be used online on the production line equipped with pneumatic spraying, airless spraying or brushing equipment.
Without containing the harmful element limited in RoHS mass in oiliness protective coating composition provided by the invention, meanwhile,
This product is volatilized without noxious material in air, does not influence environmentally friendly effect of construction environment etc.；Oiliness in the present invention, which is protected, to be applied
Feed composition configures simple process, and extemporaneous preparation when can be used, the preparation time is short, simple possible, after production can also being prepared,
It stores at room temperature, coating stabilization shelf-stability can reach 6 months or more, it may appear that precipitating, lamination, still, when use
Shaking up or re-start stirring can be used.
The production method of titanium tube of the present invention is with good economic efficiency and social benefit, in titanium production industry
With more wide popularization and application foreground.
