MONOLITHIC REFRACTORY FURNACE LININGS DESIGNED FOR RAPID COMMISSIONING

摘要

Monolithics are widely used for lining aluminium melting andholding furnaces and have many advantages in performance andsecurity. One major disadvantage is the time taken to fully cureand dry out the structure. The use of high cost pre-cast and driedpieces can reduce this down-time, but unless all the furnace isbuilt in pre-cast pieces, the need to cure and dry the in-situinstalled monolithics prevails.New materials have been developed with a different bondingsystem such that the lining does not require any curing time andall the water can be removed quickly at low temperatures. Savingsof several days can result. These new products are very versatilewith the option to install the same material by casting, pumping orshotcreting. They have excellent aluminium penetration resistanceand are well proven in service.This paper describes the product development principles and givesexamples of applications.
