These crucibles often pour liquid steel every 40-50 minutes. • The typical life of large bore metal and/or rubber furnace hoses utilized in this service can range from as little as 10 months to as long as 3 years. • Root causes of premature hose failures in a typical mini-mill: • Stress cracks in the metal hose liner caused by frequent flexing and movement when the furnace roof opens for charging, melting, and tapping. • Metal hose liners rupture from impulse cycles created by vacuum pumps when pulling spent water throughout the cooling system. • Hot scrap, slag
