Fused Silica Based Dry Vibratable Material Quartz based with fused silica addition of 15 – 50%. Bonded by boron oxide or boric acid Advantages No seam separation (mineral base is the same) Excellent thermal shock properties Disadvantage Not very good at resisting mechanical impact
• No adverse effects on the dry vibratable silica refractory linings • Estimated electrical savings of $174,000 annually. In sum, insoluble buildup and slag-related problems have become serious issues for today’s foundry operations. These problems will likely only increase as the quality of
High alumina dry linings are normally used for copper melting applications, however, silica linings are considered most suitable for brass alloys. KELLUNDITE* 400 is a high alumina based dry-vibratable refractory especially developed for lining coreless induction furnaces melting nearly all copper
Dry Vibratable Linings for Induction Furnaces. Alumina Based Linings for Steel Melt; Non Silica Specialty Alumina Linings for Ductile Iron Melting; Non Silica Specialty Mullite Linings for Grey Iron Melting; Special Installation Vibrator for Fast Dry Vibratable Installations; Porous Plug Technologies for cleaning metal in your induction furnace
Apr 19, 2018 Because of dry preparation of the mass, the heating and sintering time needed is short. The specific cost of refractory per ton of steel made is low. Silica ramming mass can safely be used up to an operating temperature of 1600 deg C. Since it expands very little, it is superior to both alumina and magnesia refractories to resist thermal shocks.
A dry vibratable substantially alkali free refractory composition is disclosed for use as a disposable liner wherein the combination of a powdered metal utilized as a high temperature binder and an organic material utilized as a low temperature binder obviates the use of alkali oxides which previously caused degradation of the permanent refractory liner materials upon which the disposable ...
We offer a unique naturally formed micro-crystalline silica-based Dry Vibratable Mix from our own 100% controlled Swedish quarry in Åmål. This raw material uniquely gives slow in line crystal transformation, in turn giving excellent thermal stability, uniform hardness and high refractoriness and has long been considered to be the benchmark ...
