【Major Breakthrough】 Jiangsu Dannai New Materials shines at the Russian International Glass Exhibition, winning high praise from global customers!

The 2025 Russian International Glass Industry Exhibition (Mir Stekla) was officially renamed "World of Glass" and made its debut on the international stage with a new brand, highlighting its leading role in the global glass industry chain. This exhibition brought together top companies from Russia, Eastern Europe, and Europe and America. Jiangsu Dannai New Materials made a stunning appearance with its high-end refractory materials for glass kilns and intelligent production solutions, attracting a large number of visitors and becoming a focal point for Chinese and foreign businessmen! Star Product Matrix Jiangsu Dannai showcased its newly developed low-carbon refractory materials and ultra-long-life glass kiln supporting technologies. With advantages such as high temperature resistance, low energy consumption, and precise matching, it attracted many international glass giants to experience it, and more than 100 technical exchanges took place on-site. "One-Stop" Service Upgrade From kiln design and material selection to construction and maintenance, Dannai launched a full life-cycle service model, providing customized solutions for customers and winning high recognition from Russian local enterprises and European engineering companies. Contract Breakthrough: Reached an annual strategic supply agreement with the top 3 glass manufacturers in Russia, with an intended order amount exceeding US\$10 million; Technology Alliance: Collaborated with a well-known German research institute to promote a joint research and development project on energy-saving technology for glass kilns; Market Expansion: Multiple engineering companies in Eastern Europe have actively invited Dannai to establish a regional technical service center to deepen local cooperation. With this exhibition as a fulcrum, Jiangsu Dannai will accelerate its layout in overseas markets, continuously promote product structure optimization and service model innovation, and explore new paths for the green, intelligent, and high-end development of the glass industry with global partners!

Selection of refractory materials for shuttle kilns

Currently, shuttle kilns are widely used in the ceramics, refractory materials, electrical porcelain, and building materials industries. Modern artistic and daily-use ceramics are also fired using shuttle kilns. During operation, the temperature, atmosphere, pressure, and various flow rates within the kiln often change due to external conditions or internal factors. The appropriate selection of refractory materials within the shuttle kiln is crucial for ensuring kiln quality. Currently, the inner linings of gas-fired shuttle kilns used in the ceramics industry can be roughly divided into the following three types: The innermost layer of the shuttle kiln lining is made of 230mm thick lightweight insulating refractory bricks, the outer layer uses 70-100mm thick ordinary alumina silicate fiber material for insulation, and the outermost layer uses a welded steel frame with steel plates to protect the internal refractory materials. The top of the shuttle kiln is an arched structure built with wedge-shaped bricks, using high-alumina or mullite lightweight insulating materials. Besides consuming slightly more fuel during firing compared to the first type, this material, when used as the inner lining of a gas-fired shuttle kiln, is essentially comparable to an all-fiber kiln, especially when using better lightweight insulating materials.

Structural characteristics and operating temperature of electrofused zirconia corundum bricks

The main refractory material used in glass industry kilns is electrofused zirconia corundum refractory brick, accounting for 70% of the entire market. Far East Refractory manufactures a large quantity of electrofused zirconia corundum bricks, strictly controlling the raw material composition, melting, casting, and annealing processes to ensure the quality of each brick. Below, we summarize the structural characteristics and usage temperature of electrofused zirconia corundum bricks. Let's take a look! Introduction to Electrofused Zirconia Corundum Bricks: Electrofused zirconia corundum bricks, also known as AZS electrofused zirconia corundum bricks, AZS bricks, cast AZS bricks, etc., are abbreviated as AZS in English. They are named according to the three chemical components of the Al2O3—Zr02—SiO2 ternary system phase diagram, arranged in order of their content. Al2O3 is represented by A, Zr02 by Z, and SiO2 by S. This abbreviation is used in the standard. For example, No. 33 cast zirconia corundum brick is abbreviated as AZS33#, No. 36 cast zirconia corundum brick is abbreviated as AZS36#, and No. 41 cast zirconia corundum brick is abbreviated as AZS41#. The numbers 33, 36, and 41 represent the alumina (Al2O3) content. For example, AZS41# electrofused zirconia corundum brick refers to an electrofused zirconia corundum brick with 41% alumina content, AZS36# refers to one with 36% alumina content, and AZS33# refers to one with 33% alumina content. Structural Characteristics of Electrofused Zirconia Corundum Bricks: Electrofused zirconia corundum bricks are formed by melting pure alumina powder and zircon sand (containing approximately 65% zirconia and 34% silica) in an electric furnace and then pouring the melt into a mold for cooling. The resulting product is a white solid. Its petrographic structure consists of a eutectic of corundum and zircon and a glassy phase. From a phase diagram perspective, it is a eutectic of corundum and zircon phases, with the glassy phase filling the spaces between the crystals.
