Aluminum content 75%-80% Refractory 1770℃ or above
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.
Home ›Case Studies ›Thailand Ceramic Fiber Supply Highland Refractory completed a 12-ton supply of ceramic fiber insulation materials for a customer in Thailand. The order consisted mainly of ceramic fiber paper, together with a smaller quantity of ceramic fiber board. The materials were prepared as one coordinated order for industrial insulation and thermal separation applications. The project included pre-shipment inspection and dispatch preparation, with on site photos available to document the condition of the products before shipment. The customer’s specific equipment and final installation positions were not disclosed.

Home ›Case Studies ›Custom High-Temperature Kiln Lining Highland Refractory completed production for a confirmed order from an overseas listed manufacturer of high-temperature industrial kilns. The project required an ultra-high-temperature ceramic fiber board lining for an electric-heating kiln, together with approximately ten custom shaped mullite insulation bricks for supporting sections of the lining. The project moved from a large one-piece lining concept to a cost-optimized modular arrangement and finally to a three-piece L-shaped solution for a grooved section. The order has been confirmed and production has been completed. The materials are currently at the pre-shipment stage; installation and operating results are not yet available.

Home ›Case Studies ›Lithuania 30T Clay Brick — Rotary Kiln Repair This case documents a 30-ton supply of fire clay brick, shaped brick and trapezoidal brick from Highland Refractory to a lime production enterprise in Lithuania. The bricks were specified for partial relining and targeted repair of a lime rotary kiln lining that had sustained localised wear, spalling and erosion damage during continuous operation. The order demonstrates Highland’s capability to produce custom-geometry refractory brick — including wedge-profile trapezoidal and non-standard shaped profiles — in factory-direct quantities for European export. 30 Tons Total Order Volume Lithuania EU Destination Lime Kiln Rotary Kiln Repair 3 Brick Types Clay · Shaped · Trapezoidal ±1 mm Dimensional Tolerance REQUEST A SHAPED FIRE CLAY BRICK QUOTE Case Study Index Client Background & Requirement The Problem: Wear, Spalling & Erosion in Lime Rotary Kiln Products Supplied: Clay, Shaped & Trapezoidal Fire Brick Quality Inspection & Export Packaging Why Highland for Custom Shaped Refractory Brick 1.

Customer Requirements A leading carbon manufacturer in the Middle East sought to optimize the thermal insulation of its interconnected pipeline systems and furnace roofs. Their legacy setup relied heavily on traditional castable refractories (totaling 880 tons across 40 baking chambers), which caused immense heat loss and excessive natural gas consumption. According to verified field testing, routine thermal cycling of these heavy castables cost the plant approximately 2.10 million RMB annually in fuel overhead alone. The client required a lightweight insulation alternative capable of drastically cutting fuel expenses while surviving the high-velocity natural gas flushing typical of Middle Eastern carbon production facilities. Application: Connected pipeline insulation and furnace roof lining inside the furnace shell Insulation Area: 1,288 square meters (replacing 880 tons of legacy castable) Key Challenge: Balancing the excellent insulation properties of fiber materials with the mechanical strength needed to resist gas erosion The Solution Highland Refractory engineered an advanced, multi-layered insulation lining using specialized Ceramic Fiber Modules wrapped securely inside the furnace shell, effectively creating a high-efficiency thermal jacket for the equipment. Precision Anchoring: Heavy-duty insulation pins were welded directly onto the steel furnace shell, ensuring the fiber modules remain structurally stable under continuous thermal stress. Anti-Erosion Protective Coating:...
