Its main task is to take the forming agent (paraffin) removed from the work piece out of the furnace and collect the molding agent as much as possible to avoid contamination of the hearth and vacuum system by the molding agent. Xiangtan Xinda Powder Metallurgy Equipment Manufacturing Co., Ltd. designed its own wax collection system. Its design goal is: the structure is simple, easy to manufacture, almost no daily maintenance; more than 95% of the input paraffin wax can be directly received in the wax receiving tank; there is almost no paraffin wax in the furnace and the main vacuum pipeline. Pollution. The entire dewaxing and wax harvesting system includes a highly efficient paraffin condensation collection system outside the furnace, in addition to a liner with controlled process doors in the furnace and a dedicated graphite extraction line. This system is particularly suitable for advanced low pressures. Carrier gas dewaxing process. The paraffin vapor in the hearth, together with the carrier gas (Ar or N2) introduced from the furnace, is passed through a dedicated outlet pipe and enters the collector of the wax collection (condensation) system under moderate vacuum conditions. About 95% of the paraffin vapor will be This is converted to liquid paraffin and collected in a wax can.
Carrier gas containing a small amount of paraffin vapor passes through the orifice and is again spun out. As the gas expands and cools, the paraffin vapor therein is converted into misty or dew-like particles, which are then collected as much as possible through denser annular collections. In order to ensure that the vacuum system is not contaminated with paraffin, before the carrier gas enters the main vacuum line, a specially designed line condenser is considered for this purpose. To ensure reliable operation, the condenser is equipped with a vacuum pressure switch to control its operating status. In order to ensure the best working vacuum for the low-pressure carrier gas dewaxing operation, an adjustable diameter butterfly valve with excellent adjustment performance is installed at the exhaust port. When PEG is removed, the carrier gas will also pass through the condenser and be discharged into the atmosphere through a dedicated channel to ignite and burn. The factory also has a dedicated manually adjusted constant temperature hot water circulation system for the dewaxing system.
The process gas introduction system requires the introduction of Ar, H2, CH4, N2 and other process gases into specific parts of the furnace (furnace or liner) during different sintering stages. The gas sources for these process gases are generally bottled or pipelined. When the pressure of the air source is adjusted to an appropriate range, each of them is connected to the process gas manifold through a dedicated solenoid valve and a rotameter (with manual adjustment valve). The direction of the gas (furnace or bladder) is switched by an electromagnetic vacuum valve. The opening/closing of all these valves is controlled by program settings to ensure accuracy. The flow of air supply is manually adjusted by a manual adjustment valve on the rotameter.
