Long Term Protection to Steel Mill Rolls

Metallizing Equipment Co (MEC) offers a complete portfolio of surface modification solutions and services requirements for steel industry. In the production of steel great demands are made on the surfaces of rollers, as they have a direct influence for the quality of the product being manufactured. In operation, these rollers are subjected to various types of hazardous conditions, for example: in continuous strip galvanizing lines the liquid zinc attacks the rolls submerged in the galvanizing bath; hearth rolls react with the furnace atmosphere at temperatures of up to 1100°C; in addition, heavy wear is caused by adhesion and abrasion; another major problem is that slag and scale can stick to the rolls; and rolls of the roller apron and the roller table, as well as deflector and anvil rolls are subjected to both high thermal and mechanical stresses. The company has developed customised coating systems, which are perfect solutions for surface related issues. Coatings exhibiting optimum properties can be produced by simultaneously applying coatings of different materials. Sealing as a post treatment may be suitable to further improve surface properties and the constitution of thermally sprayed coatings. NiCr based coatings can be fusion bonded and have properties similar to a hard weld-cladding. These coatings are best suited for applications with high bond strength requirement. Steel industry components at different stages of production line require thermal sprays for: bridle roll; sink roll; deflector roll; driver roll; pump casing; run out table (ROT) roll; coating on sink roll; rolling cones, etc.
