Name：RQ3W(RQ3)/RNW(RN)Series Pit-type Carburizing & Nitriding Furnace

Brief introduction：Q3W and RNW series furnaces are high efficient energy-saving furnaces developed on the basis of RQ3 and RN series furnaces. The furnace linings of RQ3W and RNW series furnaces are made of high quality full fibre refractory thermal insulating materials, which ensures low heat capacity and low heat conductance, reduces the loss of heat, helps to get best effect of energy saving.
