The Cna Eng Roller Hearth Furnace systems were designed for steel bars and merchant shapes. These heat treatment systems come with a fully integrated hardening, tempering and quenching, intended for continuous and high volume productions up to 60,000 lbs/hr (~27 metric tons/hr). The patented restrained roller spray quenching technology reduces distortion creating a uniform metallurgical and mechanical properties roller hearth line, that permits work with various round bars, squares beams, plates and similar shapes. Additionally, these units use special, energy saving burner technology, and are available with level II automation systems (with product tracking). They represent an excellent solution for long bar lengths up to 60" (18.5 m).
