一、低温真空渗氮炉ZD 型低温真空渗氮炉是由炉体、供气系统、真空抽气系统及测温控温系统等炉子结构组成,如图1所示。炉子本体:炉体为园筒形卧式。炉盖2处设有隔热屏3;加热元件9安装在炉内马弗5中,在有效加热区外采用双层炉壳;绝热层4采用硅酸铝耐火纤维以增加保温效果;为了使炉罐6的温度均匀,增加炉罐前后两端的由功率;碳化硅马弗做成遮蔽式后增加了热
First, the low-temperature vacuum nitriding furnace ZD-type low-temperature vacuum nitriding furnace is composed of furnace, gas supply system, vacuum exhaust system and temperature control temperature furnace structure, such as shown in Figure 1. Furnace body: Furnace body is cylindrical horizontal. The furnace cover 2 is provided with a heat shield 3; the heating element 9 is installed in the furnace muffle 5, double-layer furnace shell outside the effective heating zone; the heat insulation layer 4 adopts aluminum silicate refractory fiber to increase the heat preservation effect; The temperature of the furnace 6 is uniform, increasing the power at both ends of the furnace. The temperature of the furnace is increased by masking
