Description
Technical field
The present invention relates to a kind of stirring paddle, high temperature resistant that specifically zinc metallurgical process is used, the stirring paddle of high concentrated acid
And preparation method thereof.
Background technology
Both know about in smelting industry, zinc is needed with stirring paddle to high temperature, high concentrated acid in agitator tank in smelting process
Liquid be stirred.
At present, stirring paddle of the zinc used in smelting process includes that shaft, one end of shaft are provided with stirring blade,
Stirrer paddle and shaft are made by steel.As stirring paddle is worked in the environment of high temperature peracid, peracid can corrode
Stirring blade and shaft, high temperature can accelerate peracid to stirrer paddle and the corrosion rate of shaft.So this stirring paddle
Stirrer paddle and shaft loss are fast, and service life is shorter.The improvement project that prior art is proposed is to adopt alloy material（As breathed out
Family name's alloy）Make stirring paddle, or the surface-coated tetrafluoroethene of the stirrer paddle and shaft in stirring paddle.Using alloy material
Obtained stirring paddle service life is not long yet（Generally 3 months or so）, accordingly, it would be desirable to the number of times that stop production to overhaul is changed is more,
So that the continuous production of enterprise is poor.Side using the surface-coated tetrafluoroethene of stirrer paddle and shaft in stirring paddle
Formula manufacturing cost is higher, and tetrafluoroethene can deform and come off in use for some time, therefore, the service life of the stirring paddle
Shorter, the number of times for needing stop production to overhaul to change is also more, and the continuous production of enterprise is poor.
Content of the invention
The problem to be solved in the present invention is to provide stirring paddle of a kind of high temperature resistant, high concentrated acid and preparation method thereof, and this stirs
