Description
Technical field
The present invention relates to paint field, in particular it relates to a kind of oiliness protective coating compositions, this coating composition is at titanium
Application in pipe production, and the production method of titanium pipe.
Background technology
Use prior art at present during producing titanium pipe, after titanium ingot is incubated 4h in 900 DEG C of heating furnaces, release
Heating furnace, carries out rolling the work of titanium pipe.Owing to titanio titanium alloy is after high temperature 900 DEG C insulation 4h, when rolling titanium pipe, meeting and steel
There is " viscous titanium " in ferrum rolling equipment, roller-way and rolling capstan winch, " lacking of different depth occurs in this titanium tube-surface making rolling obtain
Meat " phenomenon, owing to being to rotate perforation, rolling when rolling titanium pipe, titanium base carries out drilling/rolling during high-speed rotation,
Due to the hot properties effect of titanio titanium alloy, it is easy to be deposited with phenomenon with ferrum, can generate TiFe phase what is more.If
Titanium tube-surface generation TiFe meets and has a strong impact on titanium material surface mechanical properties and tissue, makes titanium pipe in following process and use process
In bring various defect, loss, the defect problem such as the most corrosion-resistant；Further, since equipment " viscous titanium " causes in follow-up rolling
Journey is wanted first grinding apparatus could again roll follow-up titanium pipe.Can not continuous rolling titanium pipe or titanium material product, when wasting substantial amounts of
Between and energy consumption；Meanwhile, for ensureing dimension of inner and outer diameters precision and the surface quality of titanium pipe, manufacturer is all to be had by titanium tube-surface
It is relatively big, owing to titanium ingot is by titanium sponge reaction system, by titanium pipe that the part of " misrun " phenomenon carries out machining, so loss
Inner and outer portions machines away, and has a strong impact on cost and the lumber recovery of titanium material.
Accordingly, it would be desirable to one can effectively prevent titanium-steel bonding, thus greatly reduce titanium pipe production cost, improve to produce and imitate
The coating of rate.
Summary of the invention
It is an object of the invention to overcome the phenomenon being susceptible to titanium-steel bonding in prior art during production titanium pipe, carry

To achieve these goals, the present invention provides a kind of oiliness protective coating compositions, wherein, protects with described oiliness
The gross weight of coating composition is 100 weight portion meters, and the oiliness that described oiliness protective coating compositions contains 5-15 weight portion becomes
Membrane, the Al powder of 40-45 weight portion, the Sn powder of 0-5 weight portion and the Al of 40-45 weight portion2O3Powder.
Present invention also offers the oiliness protective coating compositions of the present invention application in titanium pipe produces.
Present invention also offers the production method of a kind of titanium pipe, wherein, the method is included in and carries out titanium ingot rolling titanium pipe
Before, in the surface-coated oiliness protective coating compositions of capstan winch and/or roller-way, wherein, described oiliness protective coating compositions
For oiliness protective coating compositions of the present invention.
The present invention provide oiliness protective coating compositions can guarantee that titanium ingot 900 DEG C rolling or perforation procedure in, not with
There is bonding reaction in steel equipment roller-way and/or capstan winch, improves lumber recovery and the production efficiency of the processing of titanium material.Such as, to climb steel
As a example by, rolling titanium material product, design is produced 10000 tons of production capacities per year, with the 1.5 tons of calculating 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 the titanium ingot of individual left and right, and each titanium ingot needs to machine away
100-200 kilogram, with the calculating of 80000 yuan/ton of titanium ingot, each titanium ingot is because " viscous titanium " phenomenon is cut partial loss at 8000-
Between 16000 yuan, meanwhile, substantial amounts of human and material resources are also spent to cut, when extra increase titanium material production cost and production
Between, and use oiliness protective coating of the present invention, substantial amounts of production is saved in the production for titanium pipe 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, every year that saving is raw
Produce cost about 21,420,000 yuan.
