  • METHOD FOR PROTECTING THE VALVE OF A MOLTEN-METAL LADLE AND FACILITATING FREE OPENING THEREOF
    Publication number: 20130001839
    Abstract: Spout-filling compositions and a method for protecting and facilitating free opening of a spout valve of a ladle are disclosed. The spout-filling compositions may comprise an iron-based ilmenite sand. More particularly, the compositions may comprise ilmenite sand in combination with a quartz and/or carbon black and/or chromite and zircon. The compositions described herein may be placed in a ladle to insulate the valve from molten metal.

  • Foamed insulating refractory
    Patent number: 4341561
    Abstract: An unfired foamed-in-place two component insulating refractory and the method for preparing the same. The composition is composed of hydraulic cement, water and an acid, though it can also include an aggregate and/or fine grain inert filler. In the process, the dry ingredients are mixed with the water to form a slurry and thereafter the acid is added to the slurry and passed through a passive mixer before the acid-slurry mixture is discharged and allowed to foam and set.
