TIME, ENERGY AND COST SAVING DURING MONOLITHIC REFRACTORY LINING INSTALLATION BY COMBINING QUICK DRY TECHNOLOGY AND GUNNING TECHNICS

摘要

The novel type of bond system, called QD NCC for Quick Dry Non Cement Castable has been applied in gunnable products with the aim to combine advantages of 1. shuttering-free installations and 2. intrinsic properties of QD NCC. Presented new products can be installed by dry or wet gunning; they give high potential of time saving in the overall refractory installation process: 1. During installation 2. Curing - not required 3. Dry out - due to higher and earlier drying rate combined with much reduced steam pressure a quicker respectively safer dry-out can be realized compared to traditional cement bonded castables.
