Suspension melting furnace

Suspension melting furnace is used for melting titanium.  Suspension melting furnace   Technical Index of 150 Series Vacuum Levitation Melting Equipments          The 150 series vacuum levitation melting equipments can be used for melting 5kg titanium, whose inner diameter is 150mm and it can also be used for melting 10kg steel products. Technical features1. "full suspend" of the whole melting process——having no non or semi molten charging adhered on the bottom and sidewall of the crucible. 2,no contamination of the melting——the content of each impurity is lower than the primitive one of the charging;3. Composition of the product is precise and well-distributed——the composition bias between the product and ingredient, and the different parts of the product iare less than 1%.4. Low energy consumption——although the power of the equipped power supply is larger than the common induction melting furnace, it can finish a melting process within 5 minutes.5. The crucible has long service life——during the past 10 years practice, the cases such as part melting of the copper crucible or micro copper dissolve in liquid charging have never happened. All of the crucibles are still in perfect condition after being used for many times.Inner diameter of cold crucible:150mmEquipping with high frequency power supply:250kw,Maximum melting temperature:1750°c,Vacuum system:mechanical pump-roots pump -diffusion pumpVacuum degree:ultimate vacuum 8×10-4Pa,vacuum degree of the diffusion pump after working 0.5h≥ 5×10-3Pa,leakage rate≤ 0.5 Pa/h,Furnace body:horizontal type,double layer water cooling, inner layer is stainless steel,inner diameter is 1000mmBasic functions and structure1.The main valve of the vacuum system is pneumatic and electromagnetic operating2. Equipping with a programmable type digital compound vacuometer3. It can inflate high-purity argon as protection. The inflating starts 0.2 seconds after the high vacuum valve's closing and finish within 30 seconds. The pressure is assignable. 4. The feeding tank can realize batch charge5. Equipping with a pneumatic titling casting mechanism, the mould can equip with heating and cooling accessories.6.the casting stock can remelting under the condition of don't destruct the argon atmosphere7. Equipping with circulating water cooling system, including the protectors of over temperature and water shortage8. The operating system includes three modes: manual mode, automatic mode and program control mode.Customized function and structure1. The structure and size of the furnace are changeable2. The materials of the furnace body, vacuum pipe and valve can use full stainless steel.3. close-cycle control of the melting process can be achieved when equipping infrared thermometer4. pressure casting mechanism and centrifugal casting mechanism can be added in casting mechanisms5. Multiple-melting structure——under the condition of don't destruct the argon atmosphere, the second and third round of melting and casting can be taken after finished the first melting and casting. The times of melting and casting are decided through the supply-side and demand-side's consultation.6. group casting and continuous casting functions can be added
