氮化硅加热元件保护管

低能耗

采用浸渍式加热方式，热源位于铝液的中部，因此传热性能优异，相对于以往上部辐射式加热方式，可以极大减少电能的消耗。

提高铝液品质

由于热源位于铝液中部，热量自下而上传递，因此铝液自上而下形成对流，充分保证铝液受热均匀，炉上部的铝液不会因过热而氧化，降低了铝的损耗，使得铝液品质得于提高，同时减少了炉壁结瘤的损害。

长寿命

具有很强的耐腐蚀性，在铝溶液中不会渗透，同时其具备陶瓷类产品的最高强度及优异的耐热冲击性能，大大延长了使用寿命。

Silicon Nitride Heater Protection Tubes

Energy Saving

The immersion heating method is adopted, and the heat source is located in the middle of the molten aluminum, so the heat transfer performance is excellent. Comparing with the previous upper radiation heating methods, the power consumption can be greatly reduced.

High Quality of Liquid Aluminum

Since the heaters & protection tube are located in the middle of the molten aluminum and the heat is transferred from bottom to top, the molten aluminum forms convection from top to bottom, which fully ensures that the molten aluminum is heated evenly, and the molten aluminum in the upper part of the furnace will not be oxidized due to overheating, which reduces the loss of aluminum. The quality of molten aluminum can be improved while reducing the damage of furnace wall nodules.

long serving life

It has strong corrosion resistance and will not be penetrated in aluminum solution. At the same time, it has the highest strength and excellent thermal shock resistance, which greatly extends the serving life.
