Aluminum Melting Furnace Construction Site - Xinhongji Refractory

图片
An aluminum melting furnace is a critical asset in foundries and metal processing facilities, designed for efficiently melting aluminum scrap, ingots, or sows. Modern furnace construction prioritizes energy efficiency, operational safety, and melt quality. The construction process begins with detailed engineering design, selecting appropriate refractory materials capable of withstanding extreme temperatures (up to 1200°C) and resisting corrosive molten aluminum. The furnace structure, typically a steel shell, is lined with multiple layers of high-grade insulation and specialized refractories like alumina-silica bricks or castables to minimize heat loss. Key components are meticulously installed, including the heating system (which can be fuel-fired using natural gas or oil, or electric resistance/element-based), the robust tilting mechanism for molten metal pouring, and advanced control systems for precise temperature management and process automation. Construction emphasizes creating ...

Special-Shaped Lightweight Mullite Bricks - Xinhongji Refractory

图片
Anisometric lightweight mullite brick is an advanced refractory material renowned for its exceptional thermal efficiency and structural integrity. Composed primarily of high-purity mullite (3Al2O3·2SiO2), it features a unique anisotropic pore structure deliberately engineered to minimize density while maximizing mechanical strength. This controlled porosity, typically achieving densities between 1.0-1.2 g/cm³, results in significantly lower thermal conductivity compared to conventional dense refractories, leading to substantial energy savings in high-temperature industrial furnaces. Its key characteristics include outstanding resistance to thermal shock, excellent creep resistance under load at temperatures up to 1600°C, and superior chemical stability against corrosive atmospheres. The brick's anisometric, or non-uniform, grain orientation further enhances its thermal shock stability and spalling resistance. These properties make it an ideal lining material for various thermal pro...

Packing and Containerization in a Refractory Brick Production - Xinhongji Refractory

图片
The final, critical stage in a refractory brick production line is the meticulous packing and containerization process, designed to ensure products reach customers in perfect condition. Given the fragile nature and high density of these bricks, specialized packaging solutions are paramount. The process begins with the careful stacking of bricks onto robust, custom-sized wooden pallets. To prevent shifting and edge damage during transit, bricks are often interlaid with protective cardboard or plastic sheets. The stacked pallet is then securely strapped with steel or plastic bands. Subsequently, it is fully enveloped in heavy-duty, weather-resistant polyethylene stretch film. This wrapping provides a tight, unitized load, shielding the bricks from moisture, dust, and mechanical abrasion. For export shipments, these stabilized pallets are efficiently loaded into standard shipping containers. Strategic placement and bracing within the container are essential to withstand the rigors of long...

Production Video Of Refractory Castable Production Workshop - Xinhongji Refractory

图片
Refractory castables are monolithic linings composed of heat-resistant aggregates, powders, and binders, designed to withstand extreme temperatures and harsh conditions in industrial furnaces and kilns. Their production involves precise formulation, where raw materials like calcined alumina, fire clay, and calcium aluminate cement are carefully selected and proportioned. These dry mixtures are then processed through advanced mixing and homogenization equipment to ensure consistency. Critical control points include particle size distribution and binder content, which directly influence the castable's workability, density, strength, and final performance. Upon installation with water, the material becomes a pourable mass that sets into a robust solid. Modern production also emphasizes developing low-cement and ultra-low cement castables for superior high-temperature mechanical properties and corrosion resistance, making them vital for industries such as steel, cement, and petrochemic...
