Abstract

Production of insulating refractory bricks was completely changed in P-D Refractories CZ over the last 30 years. The main changes relate to decreased bulk density and increased classification temperature. Another important aspect is shorter and shorter required delivery term, which changed the classic production way of extruding the plastic mixtures. The main application is the glass industry (mainly for fireclay, mullite and silica insulating bricks). This range of insulating bricks includes also large blocks for glass tank bottom. Properties of bricks made by a new production technique not only for the basic tests required by the customer had to be set up, but also for the additional tests that include for example refractoriness under load and creep.
