Protective Coating Lubricants

Anti scale compounds or anti oxidation compounds manufactured by SPS have proven to effectively either eliminate or substantially reduce scaling and decarburisation during heat treatment, hot forging and hot rolling. Some of the benefits due to use of anti-scale compounds made by SPS are:

• Minimum scaling & decarburisation of metals during heat treatment & re-heating.
• Prevention of quench cracking after heat treatment.
• Reduced operations like shot blasting, machining, grinding, etc. due to minimal scaling after heat treatment.
• Elimination of scale pit marks on forged & cast components.
• Material saving possible as material allowance for machining and grinding of scale pits on surface of components is reduced.
• Improved surface properties due to reduced decarburisation.

SPS manufactures various anti scale compounds to suit diverse metal working applications like heat treatment, hot forging and hot rolling.

Selective gas nitriding is done by use of special masking compound manufactured by SPS.

The areas where hardness is to be avoided during nitriding is coated with the masking compound. This ensures prevention of hardness in desired areas. Benefits of using anti nitriding compound made by SPS are:

• Prevents nitriding on areas of component where nitriding is not desired.
• Reduces consumption of ammonia gas during nitriding. 

Eco friendly, non polluting hot forging lubricants that help in increasing die life are the need of the hour of the hot forging industry. SPS manufactures graphiteless, water soluble, non-polluting lubricants which have proven to increase hot forging die life from 30% up to 100% as confirmed by customers. This hot forging lubricants is enabled as the wearing of dies is greatly reduced by good lubrication. Load on forging presses and hammers are also reduced. Benefits of using hot forging die lubricants made by SPS are:

• Increased hot forging die life.
• Improved surface finish of forged components.
• Environment friendly and no smoke emission observed during use.
• Economical even as compared to furnace oil.
• Lubricant stirring equipment not required. Manual application possible.

To suit all requirements of the forging industry, SPS range of lubricants includes oil based lubricants, graphite based water miscible lubricants and graphiteless water soluble lubricants. Graphiteless, water soluble lubricants are internationally accepted due to their non-polluting, environment friendly nature.

Tapping lubricants manufactured by SPS are found very effective in cases of materials that are hard to machine, like austenitic stainless steel, nickel based alloys and aluminium alloys. Huge savings in cost of tools and their productivity in metal working operations are enabled.  Benefits of using tapping lubricants made by SPS are:

• Reduced friction and cutting edge temperature of tapping tool.
• Lowered cutting force and torque.
• Retained sharpness and hardness of cutting edges.
• Improved thread finish.
• Prolonged tapping tool life leading to increased productivity.

These tapping lubricants are found useful by manufacturers of machine tools, heavy machines, valves, pneumatic equipments, hydraulic systems, electrical fittings and every unit requiring machine tapping or hand tapping.

Energy saving in furnace operations is enabled by a special refractory coating manufactured by SPS. The refractory lining life is increased due to application of ESPON refractory coating, which enhances thermal shock resistance of refractory lining. Benefits of using refractory coating made by SPS are:

• Improved emissivity leading to energy saving.
• Faster start-up time of furnaces.
• Increased refractory lining life.

Increased emissivity of refractory lining due to application of refractory coating enables faster heat up time of furnaces and longer retention of heat inside furnace, even after shutting off furnace. Increased emissivity of refractory and retention of heat inside furnace leads to reduced fuel consumption. Fortifying of refractory lining with refractory coating substantially increases refractory lining life and reduces frequent maintenance downtime.
