What are the requirements of the holding furnace It is different from the general mixing furnace, generally should meet the following three requirements: 1. It can control the temperature of the liquid metal during drawing, so that the molten metal is always maintained within a certain temperature range, so as to ensure the normal production of continuous casting and the best quality of the ingot.Vacuum Brazing Technology of Stainless Steel Radiator Core 2. The furnace is required to vibrate back and forth within a certain range. For certain alloys, horizontal continuous casting must be vibrated to obtain good ingot surface quality and crystalline structure. The amplitude range is 0-15 mm, and the vibration frequency is 0-200 times per minute.Heat Treatment of DZ4 Alloy in High Pressure Gas Quenching Vacuum Furnace 3. The front of the furnace body should be easy to install the mold, so that the liquid metal in the furnace can directly enter the mold in a short distance.Multi-purpose vacuum heat treatment equipment Therefore, the holding furnace is made into a horizontal power frequency induction furnace with an iron core with a slightly square body.Surgical instruments stainless steel vacuum heat treatment This kind of furnace can be tilted and rotated and cannot be tilted. Although the structure of the tiltable furnace is more complicated , but can prevent the danger of liquid metal shock during leakage. In the process of low pressure casting, the furnace body has to bear a large load, and the furnace shell must have sufficient rigidity and sealing.Die Steel & Vacuum Heat Treatment News
