(PDF) Glass melting furnace refractories and refractory ...
For alkali-based glasses, many glass makers have reported problems regarding degradation of superstructure refractories, particularly silica. Typically affected are the areas where silica is ...
Characterization and identification of local defects in glass
The crystalline defects may be caused by the crys- tallization of the glass itself or by crystal formation from reactions with refractory material or contamination, or from undissolved raw materials, etc.
Boundary Layers Refractory/Glass Melt and Glass Defects ...
The reaction between refractories and glass melts is determined by the diffusion of the different ions from the glass melt into the refractory material and vice versa. The connected solution reactions lead to the formation of a saturation boundary layer, which influences the corrosion behaviour and the glass defect potential. The behaviour of the boundary layers of various …
Glass defects originating from glass melt/fused cast AZS ...
Problem definition. The interaction of glass melt and refractories in the industrial glass melting tanks has a large impact on the glass quality. Due to the interaction of the glass melt with refractory materials, different kinds of inhomogeneities like stones, knots, cords and bubbles are generated.
Glass Refractory : u/ricehusk
Refractory related glass defects Glass defects occur in many different forms while the defect sources exhibit a considerable diversity. For example, two defects may have the same structure and character but an origin which comes from different sources and driven by different mechanisms.

Defects and contamination | Glass property measurement ...
Laboratory analysis includes composition analysis of inclusions, stone, cord, knot, bubbles and blisters to surface contamination, delamination, misting, bloom and the assessment of forming defects and quality concerns in finished products. As experts in glass we can simply report upon simple composition and causes of defects or provide technical support to provide solutions and quickly ...
Glass container defects Causes & remedies
recognize the defects and understand what remedies to use in order to eliminate them. When a glass container fails on the customer’s filling line because of a manufacturing defect, the reputation of glass suffers, which results in a loss of customer goodwill. Remedies offered hopefully give you a basic understanding of defects and their causes.
Lining (Refractory) - an overview | ScienceDirect Topics
Jan 26, 2010 · Defects in the refractory lining or moisture-laden areas of insulation will therefore affect the exterior surface temperature uniformity. The usual approach to this kind of inspection would be to thermally map the exterior surfaces and use this as a baseline for subsequent surveys whereby deterioration may be monitored over time through comparison.
Refractory Materials: Fused Cast AZS Exudation And Glass ...
Fused Cast AZS Exudation And Glass Defects Fused cast AZS block is the most widely used refractory material in the demanding areas. It is thought as the leading cause of knot and cord defects. Fused cast AZS exudation in glass contact is the main cause of impaired performance of AZS under particular working conditions.

chemistry, he joined GS. Currently, he is a laboratory engineer responsible for the bubble glass defect analysis, glass properties measurement, refractory testing and high temperature observation testing of the glass batches. Erik Muijsenberg (GS) Erik Muijsenberg graduated from Mechanical engineering at the University of Eindhoven in 1990.
Refractory Corrosion and Glass Defects _Zhengzhou Sunrise ...
The refractory materials used in glass furnaces are exposed to high temperature and mechanical corrosion during the operation, which results in corrosion of refractories and glass defects. Silica stone is a kind of acid refractory mainly made from tridymite, cristobalite and a small amount of residual quartz as well as glass phase.
Glass Service: defects training success in Istanbul ...
Jan 15, 2020 · Glass Service (GS) and CQ Massó partnered with Şişecam last November to organise a glass defects and refractory training day for attendees at the Şişecam International Glass Conference in Istanbul. The main conference was attended by 500 professionals from all over the world, interested in learning more about sustainable glass production.
Refractory Selection for the Container Glass Furnace ...
The drawback is the exudation of the glass phase, which will cause glass defects such as stones and stripes. Reducing the glass phase can effectively reduce the exudation of the glass phase. Fused cast AZS with a lower glass phase is developed for the use of superstructure.
