Development and use of high alumina plastic in reheating furnaces of Tisco

New a days plastic refractories are gaining wide popularity in Steel Plants and other industries due to certain advantages in application. They have got the advantageous property of deformability without rupture and retentivity of deformed shape after release of stress. They are monolithics prepared in stiff plastic condition of proper workability for use without further preparation. They are mixtures of graded refractory aggregate and a plastic fraction with or without plasticizers. Their application is easy and time saving. They can be applied in intricate positions locally without disturbing the rest of the lining and can be moulded to any shape in situ, thus eliminating the requirement of special refractory shapes
