Silicon carbide plates are mainly composed of silicon carbide (SiC) as the aggregate (with a content usually ≥ 80%).
High alumina poly light brick is a high quality lightweight refractory material.
Checker bricks are heat transfer media used in the regenerative chambers of blast furnaces and hot blast stoves.
Customer Needs A manufacturing company located in Poland was in the process of constructing a new pusher kiln for continuous high-temperature firing of ceramic products. The kiln was designed to operate under long production cycles with stable thermal conditions, making energy efficiency and temperature uniformity critical performance requirements from the very beginning. During the kiln design and construction stage, the customer conducted an internal energy assessment and identified several common challenges associated with traditional pusher kiln systems: Significant radiant heat loss from kiln walls and roof surfaces Difficulty maintaining uniform temperature distribution across the firing zone during continuous operation High fuel consumption, particularly during heating-up and load changes Rising energy costs putting pressure on long-term operating budgets Since the kiln had not yet entered production, the customer aimed to integrate an energy optimization solution during construction, rather than relying on post-commissioning retrofits. The solution needed to be technically reliable, cost-effective, and compatible with existing refractory linings—without changing kiln dimensions, firing curves, or production rhythm. Get product information Solution Provided After reviewing the kiln’s structural design, refractory materials, and operating temperature range (approximately 1,250–1,300°C), a High Emissivity Coating was proposed as part of the kiln’s hot-face surface treatment. Application Scope Roof...

An Energy-Efficiency Project for a Customer in Germany Customer Requirement A customer located in Germany was involved in the construction of a new shuttle kiln for high-temperature firing applications. During the kiln design and construction phase, the customer aimed to improve thermal efficiency and heat utilization from the outset, rather than relying solely on traditional refractory lining solutions. The key requirements identified by the customer included: Improved radiative heat transfer inside the shuttle kiln Reduced fuel consumption during repeated firing cycles More uniform temperature distribution within the kiln chamber Compatibility with standard refractory linings used in shuttle kilns A solution that could be integrated during kiln construction, without increasing structural complexity Given Germany’s strict energy efficiency standards and rising fuel costs, the customer required a solution that could deliver measurable energy savings while supporting stable and repeatable kiln operation. Solution Provided Based on the shuttle kiln configuration and operating temperature range, a High Emissivity Coating was selected and applied as part of the kiln construction process. Technical Rationale High emissivity coating enhances the thermal radiation capability of refractory surfaces by increasing surface emissivity. This allows more heat to be transferred efficiently from the kiln atmosphere to the product load, improving...

An Energy-Efficiency Upgrade Project for a Customer in Australia Customer Requirement A customer located in Australia operates an industrial tunnel kiln used for continuous high-temperature firing. With rising energy costs and increasing pressure to improve operational efficiency, the customer sought a practical solution to enhance heat utilization within the kiln without making major structural modifications. The key challenges identified by the customer included: High fuel consumption during long-term tunnel kiln operation Uneven heat distribution inside the kiln chamber Heat loss through kiln walls and refractory surfaces Limited flexibility to redesign the kiln structure A strong need to improve energy efficiency while keeping downtime minimal The customer required a solution that could be applied to the existing kiln lining, improve thermal radiation efficiency, and deliver measurable energy-saving results under continuous production conditions. Get Free Quote Solution Provided Based on the kiln type and operating conditions, a High Emissivity Coating was recommended and supplied as an energy-efficiency upgrade solution. Product Selection and Technical Rationale High emissivity coating is designed to enhance the radiative heat transfer inside high-temperature equipment such as tunnel kilns. By increasing the surface emissivity of refractory linings, more heat is transferred to the product load rather than being lost...

Project Background This case study presents a custom fire clay brick supply project for a customer located in the Middle East. The customer required refractory bricks for the construction of a commercial pizza oven, where stable temperature control, even heat distribution, and precise brick dimensions were essential for daily operation. Unlike industrial furnaces, pizza ovens require refractory materials that not only withstand high temperatures but also provide consistent thermal performance suitable for food preparation environments. The customer therefore emphasized dimensional accuracy, surface quality, and installation efficiency. Customer Requirement The customer planned to build a pizza oven using square fire clay bricks with fixed dimensions and requested a solution that could be applied directly without on-site modification. The main requirements were clearly defined: Product type: Fire clay bricks Application: Pizza oven inner lining and baking surface Brick size: 300 × 300 × 30 mm Production method: Customized mold production Installation goal: Precise fitting and clean oven structure Logistics: International shipment with proper packaging and shipment confirmation Because the bricks would be used in direct contact with high temperatures during baking, the customer required a material that could maintain stable performance under repeated heating cycles while preserving structural integrity. Standard refractory brick...
