FIELD OF THE INVENTION
The present invention relates a paint for protecting materials from wear. More
particularly, the present invention relates to a refractory based paint coating on
galvanizing pot hardware for protecting wear and for easy maintenance.
BACKGROUND OF THE INVENTION
Different pot materials have been tried all over the world and tested, for
ensuring long life of the main zinc pot housing the molten zinc, in a continuous
galvanizing line. Using a simple refractory based coating, in water medium, on
the surface of pot hardware like sink-roll arms and brackets and on the inner wall
of the pot has been found to remarkable reduce the erosion of the mother metal
by zinc, which is corrosive to iron at higher temperatures.
Prior to its usage, the pot walls used to get eroded over time and lead to
unprecedented leakage and puncture at odd places. The sink roll arms/ brackets
used to get eaten up by the molten zinc and replacement or repair became time-
consuming and hazardous to the contractors.
In order to overcome such prior Art practical problem, the present invention
developed a refractory paint coating which on application to material surface
eliminates such problem.
OBJECTS OF THE INVENTION
It is the therefore an object of the present invention to propose a refractory
based paint coating on galvanizing pot ware for protecting wear which eliminates
the disadvantages of prior Art.

3
Another object of the present invention is to propose a refractory based paint
coating on galvanizing pot ware for protecting wear which helps in maintenance
work.
A further object of the present invention is to propose a refractory based paint
coating on galvanizing pot wear for protecting wear which leds to longer life of
galvanizing pot and the hardware.
A still further objection of the present invention is to propose a refractory based
paint coating on galvanizing pot wear for protecting wear which prevent the pot
from cracking.
SUMMARY OF THE INVENTION
The refractory based paint that is used to protect the surface of the hardware in
the galvanizing pot, including the sink roll arms and the inner surface of the steel
tank is comprising of a aqueous solution of refractory materials having following
composition
Graphite -18 -20%
Silica Flour - 45 - 50%
Silim anite - 15 - 17%
Emc - 1.5 - 2%
Balance - water
The refractory based paint made of the above mentioned composition is applied
as it is on clean metal surface with the help a paint brush; Once it is dried, a
second Coat is applied and depending upon the severity of attack.

4
A third coat can also be applied after proper drying out of the second coat.
Using of three coats of this paint on the fresh surface, prior to the first usage has
been found to prevent the arrack. This is not only led to longer life of the pot
and the hardware, it also made maintenance a lot easier, by cleaning of the
brackets etc.
TESTING RESULT
A water based paint with refractory component was applied three coats on the
zinc pot and was found very effective in a hostile environment of 450° - 470° C,
amidst a continuous turbulence of the zinc bath processing more than 100000
tons of CR Coil passing through the bath in a normal campaign. An scanning
electron Microcopies analysis was carried out of the inner walls of the zinc pot
treated with the paint revealed the differential presence of the effective
elements.
