主要特点
Heat insulating materials adopt Alumina fiber inorganic ones, which is formed with vacuum absorption, environmental protecting and energy saving.
Furnace body is double air cooling structure to control furnace surface Temp. no more than 60℃ when furnace is heated into max. Temp.
炉体采用双层风冷结构，炉子烧到最高温度时，壳体表面温度低于60℃
Furnace body use super-light high alumina fiber material, with the features of low hot melt, flexible Temp. control and energy saving, etc.
炉体采用超轻质高铝纤维材料，具有热熔小，温度升降控制灵活、节能等特点。
Mechanical pump and vacuum unit are optional according to vacuum degree requirement, very suitable for test and small batch production.
设备可根据真空度的需要分别选用机械泵或真空机组，非常适合于试验和小批量生产之用。

Attention
注意事项
The equipment is not sealed, and can not be put into toxic, harmful, inflammable and explosive gas. Can add the inlet port to pass through the inert gas or oxygen.
此设备腔体不密封，不能通入有毒有害，易燃易爆气体。可以加装进气接头，通惰性气体或者氧气
Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating.
在使用过程中炉膛表面可能出现细小裂纹。这是正常情况，裂纹可以用氧化铝涂层修复。
You shall place the sample in to a crucible. Never place sample on the chamber bottom directly.
应该把样品放进坩埚里。不要把样品直接放在腔底。
