Refractory Fibre Module

Description Z-Blok Modules Z-Blok are made from high quality spun-fibre blanket, folded and pre-compressed to a specified density. The fixing system comprises two beams positioned within the folds and connected by tabs to an exterior channel, mounted transversely and centrally across the back of the modules. During the installation, the modules are further compressed, the resilience of the fibre and recovery after the restraining bands are removed ensuring tightly-compressed inter-modular joints. T-Module Stainless steel rods are inserted in the module and fasten to the stainless steel plate that is welded or bolted to the casing. The module is bound up to certain shape and restricted within certain sizes. After the modules are fixed onto the furnace shell, the bandaging are cut and the modules and so to form an integrated insulating lining. The anchor system in remote from he module hot face, maintaining the metal components at a relatively low temperature.Features Z-Blok Modules and T-Blok Modules offer several of the following advantages to both the furnace constructor and the end user. The anchorage on the back allows for both in-line and parquet installation. The decompression of the blanket folds gives tightly sealed intermodular joints with both configurations. The resilient blanket is resistant to mechanical damage. The resilience of the blanket can accommodate some flexure of the furnace casing without opening gaps between modules. Light weight, giving low heat absorption in the insulation. Low thermal conductivity give high thermal efficiency. Total resistance to thermal shock. No drying or curing required – so available for production operation immediately after installation. The anchor is remote form the module hot face, maintaining the metal components at a relatively low temperature. The anchor system can be secured to the furnace casing with a variety of fasteners: power activated fasteners, welded studs or cotter key-life pins, nuts and bolts, self-tapping screws or pop rivets.
