Metal Fabrication

SolMix® is the brand name of a technology patented by SOL for producing directly on customer premises gas mix containing inert elements (nitrogen), reductants (hydrogen) and non-decarbonisers (carbon dioxide). Its principal application is the thermal treatment of metals, in particular in carbo cement production, carbonitriding and tempering. SolMix® technology allows customers to control their thermal treatment by choosing the carbon potential: the system is flexible and can handle automatically all the variables that influence the process such as the ratio between the reactants, the temperature and working pressure, the catalysing system and related chemical reactions.

Thanks to the considerable flexibility in terms of production capacity in relation to the immediate needs of treatment furnaces and accurate and certified control of the quality of the mixture produced, SolMix is a technology that makes it possible to hold down costs, methane and energy consumption and so is of low environmental impact.

The main advantages of SolMix® technology are:

• Control and management of the carbon potential of the mixture produced that can be modified on the basis of the specific thermal treatment, reducing the corrective action required from the customer on the treatment furnace with addition of enriching methane or air.
• Control and management of the variables that regulate the process, including temperature, reaction pressure and composition of the reactive mix, reduced maintenance and better performance over time of the plant.
• Great flexibility in the production of the mixture that makes it possible to produce only the amount of gas effectively needed by the furnaces.
• Accurate and continuous control of the composition of the end mixture through analysis of the amount of carbon monoxide (CO) and the residual amount of carbon dioxide (CO₂) and methane (CH₄) with automatic regulation of the reaction parameters.
