The Hot Spray Marking Machine is designed for the marking of slabs and blooms, even in the harsh environment
of steel plants. Marking is performed by blowing liquid metal which is melt in an electric arc between two wires to
the surface of the product. Hot Spray Marking Machines are distinguished especially by marking of long-lasting
characters, which can vary in size and number of lines depending on individual customer requirements.
The complete equipment is manufactured using standardised modules, which result in high reliability and low
maintenance of equipment and specially selected electrical and mechanical parts that are designed, well tested
and proven to function in heavy industries.
Low production costs
 Low operating costs due to use of standard aluminium welding wires up to 900 °C
 Low consumables costs, only electrical and pneumatic media supply is necessary
High visibility
 Large characters offer a high visibility even from the crane operator
High durability
 Durability of marking at least a half year at outdoor storage
Easy maintenance
 Simplicity of system allows an easy maintenance

The Hot Spray machine frame consists of a robust
fabricated construction with linear rails and safety
devices for the marking head. The characters are
generated by an electrical writing movement of the
marking head with x and y axis driven by servo
motors.
The machine is controlled by a PLC type Siemens
S7 with standard interfaces to steel plant equipment
and fault diagnostic system.
