Features a high-strength carbon steel frame with a solid welded structure. It provides overall structural support, prevents deformation, and improves operational stability.
Filled between the steel shell and the refractory lining. It greatly reduces heat loss of molten aluminum and cuts energy consumption.
Serves as the direct contact layer with molten aluminum. It uses anti-stick aluminum refractory materials, effectively reduces slag adhesion, and is convenient for cleaning.
Slows down the temperature drop of molten aluminum and prevents secondary oxidation.
Superior thermal insulation performance effectively reduces molten aluminum temperature drop, with temperature loss of only ≤5℃ per meter. Stable melt temperature guarantees consistent casting quality and lowers energy consumption during long-term production.
2.Non-stick Aluminum & Anti-dross Surface
Ultra-smooth inner lining prevents molten aluminum adhesion and dross buildup. It eliminates metal wetting issues, greatly reduces oxide inclusions, keeps aluminum liquid pure, and simplifies daily cleaning and maintenance.
3.High Erosion & Thermal Shock Resistance
Made of high-strength refractory material, it delivers outstanding resistance to high-temperature scouring, thermal shock and alloy corrosion. It is ideal for long-term continuous aluminum casting and molten metal transfer.
4.No Contamination & Higher Metal Purity
The inert material formula ensures no particle shedding and no chemical reaction with molten aluminum. It effectively improves finished product yield and prevents secondary pollution during metal transfer.
5.Integral Forming & High Dimensional Accuracy
The one-piece integrated molding process delivers a stable structure, precise dimensions and good air tightness. The smooth internal flow channel ensures unobstructed aluminum flow and prevents liquid leakage and splashing.
6.Long Service Life & Cost-saving
The durable, wear-resistant construction extends service life under continuous industrial operation. It reduces the need for frequent replacements and downtime losses, greatly cutting overall production and maintenance costs.
7.Customizable & Easy Installation
It supports customized size, structure and insulated cover tailored to specific production lines. The modular design enables quick installation and flexible adaptation to various aluminum casting production scenarios.
