AT232B Batch-type Low Temperature Carbide Furnace consists of pre-heating tube, working furnace tube, steam generator and flow controlling system. The pre-heating tube has two heating sections and the working furnace tube has three heating sections. Pre-heat steam produced by steam generator, air or oxygen to 600℃ in the pre-heating tube and then enters into the working heating furnace tube through pressure-adjusting valve and flowmeter. The pre-heat tube is connected with the working furnace tube by a rapid-connection connector and they are horizontally laid in rank. The heating furnace for the working furnace tube is open-able and dischargeable, convenient to observe. There is stainless steel filtering screen in the pre-heating tube for uniformly heating gas.
