Sinter-HIP Furnace(6 MPA Sintering Furnace,Which Is Graphite-Heated System And Designed For Cemented Carbide)
Design standard
The cemented carbide sinter-HIP furnace is a single chamber, double door horizontal and periodic heating structure. The design is easy to load and unload and maintain, and the whole process is controlled automatically. Realize full load continuous operation, 300 furnace times/year or 300 working days/year. Graphite element resistance heating (low voltage, large current); With a plurality of heating units, each unit is independently controlled temperature; Automatic control function, safety interlock function, the whole process by computer automatic control, monitoring, tracking, fault self-diagnosis simulation display and record. PLC, industrial computer (PC) control to realize the whole process of a key start, real-time dynamic monitoring, computer temperature, pressure, vacuum degree and other parameters to save, safe and reliable alarm interlock.
General requirements of the equipment
It mainly used for carbide dewaxing (vacuum AR carrier gas dewaxing and hydrogen micro-positive pressure dewaxing), vacuum sintering, partial pressure sintering, pressure sintering, rapid cooling and other processes. It meets the strict requirements of furnace temperature uniformity and atmosphere uniformity in the sintering process of cemented carbide, and the furnace structure design is advanced and reasonable, which is easy to use, operate and maintain. The main supporting components (control components, sensors, graphite heating element, thermocouple, main control valve, vacuum pump, etc.) have the current international advanced level, can adapt to the long-term, stable, reliable mass production requirements. At the same time, the equipment to meet the national energy saving, environmental protection requirements.
Equipment technical parameters

| Furnace shell design operating times | 6000 furnace/time |
| Effective working area(W*H*L) | 500mm×500mm×1800mm |
| Max.loading weight | 1500kg |
| Max.design temperature | 1600℃(Under the circumstance of vacuum sintering,heating up furnace to 1600℃) |
| Max.working temperature | 1500℃(Under the status of vacuum and pressurization) |
| Max.design pressure | 60bar |
| Max.working pressure | 58bar |
| Pumping speed | Within 30 minutes after the pump starts, the vacuum degree can reach 5Pa. After the pump reaches 5Pa and then pumps for 30 minutes, the ultimate vacuum value can reach 1Pa (after the oven, in the case of cold, air and dry). |
| Leakage rate | ≤3Pa/h(Measure the ultimate vacuum after heating up the furnace,stop the operation of the pump set and start the test. Under the condition of empty furnace, clean, cold state, average value within 3 hours). |
| Cooling time of full loaded | When the furnace is fully loaded with charging amount, the cooling time of sintering temperature from 1450℃ to 100℃ is less than 6 hours (water temperature is less than 30℃,55bar is less than 58bar). |
| Filling high pressure argon gas | Adopt intermittent stable inflation, charging time can be set. The system accurately matches the relationship between the inflating volume and the time to ensure the inflating follow. |
| Wax yield rate | ≥98%(10Kg pure paraffin wax, argon negative pressure dewaxing. Maximum three averages). |
| Pressurized time | Pressure to 58Bar, ≤20min can be set (the air source pressure is stable in the range of 80bar-100bar). |
| UPS guarantee time | Power the indicator lamp and control the furnace when the power is off, the time is ≥60 minutes. |
| Heating up speed | ≤5℃/mim(Empty furnace) |
| Heating power | About 600KVA(The power of heat transformer is related to heating up speed). |
| Temperature control mode | 3 zone temperature control |
| The uniformity of heating area | During vacuum and pressure sintering, temperature uniformity at pressure (58bar) 1450℃ : high pressure gas is charged at the maximum allowable speed, temperature fluctuation ≤±5℃. |
After sales:
1. Installation, Commissioning and Acceptance
We do installation, commissioning and acceptance in buyer's plant.During the installation and commissioning period, the commissioning personnel shall be provided free of charge by the demander according to the staff standard.
The equipment shipped to the buyer, the seller received the buyer's notification, both within a week to carry the equipment out of the box together, then check the equipment and all components according to the packing list . Including equipment accessories, spare parts and special tools, attached manual and technical documents, etc. It can be installed after the acceptance check of equipment.
After installation and debugging, the equipment shall be accepted according to the technical accessories.
2. Training
When taking-over the Furnace to the customer, We will give a staff training to customer. The operating personnel of the customer should join to commission,test the furnace, when installing at customer’s company.
This is practical operation training and practical maintenance training,and our technical personnel will telling the basic principle,equipment maintenance knowledge,And the common fault handling measures.We can training 2 ~ 3 workers. ( Training how to maintenance and operating.)
3. Warranty period
The warranty period of the equipment is 12 months, which starts from the date of installation and debugging of the supplier. Equipment failure happens, after-sales service personnel shall give solutions within 2 hours, after receiving the buyer's notification . If it is need to go to the site for treatment , operators dispatched by seller should arrive at the site within 48 hours after go aboard. In case of emergency,operators should arrive at the site within 48 hours after go aboard, and continue to make repairs until the fault is removed and the equipment returns to normal.
