Operation independence and easy maintain machine for sintering metal product
Device color matching:
The surface of furnace body, transformer, control cabinet and vacuum pump is light grey (color code: RAL7035). The furnace foot, pump frame and support are matched by sky blue (color code: RAL5015).The groove is stainless steel, the support is galvanized, the transformer is placed on the ground.
General equipment requirements:
The equipment is mainly used for dewaxing of cemented carbide (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 requirement of uniformity of furnace temperature and atmosphere in sintering process of cemented carbide.
Technical parameters of equipment:
Service life of furnace shell
20 years service life
Furnace shell working time
Effective working zone size
Maximum design temperature
1600℃(Under vacuum sintering conditions,drying the furnace 1600℃)
Maximum working temperature
1500℃ (Under the vacuum and pressure condition.)
Maximum design pressure
Maximum working pressure
The vacuum degree can reach 5Pa within 30min after the pump is started, and the limit vacuum value can reach 1Pa after pumping for 30min after reaching 5Pa
(After drying the furnace,under the empty furnace, clean and cold state)
(Measuring the limit vacuum after drying the furnace, stop the operation of the pump group and start the test.Average within 3 hours in empty furnace, clean and cold state)
Cooling time of loading full furnace
When the furnace is fully loaded,the cooling time of sintering temperature from 1450℃ to 100℃ is less than ar equal to 6 hours(water temperature ≤30℃,55bar≤pressure≤58bar)
Filling high pressure argon gas
It adopts intermittent stable inflation, inflation time can be set.The system accurately matches the relationship between charging volume and time to ensure the following of charging.
Wax collecting rate
≥98%(10kg parafin refind wax ,Ar negative pressure dewaxing ,three averages at most
The pressurization time to 58Bar is less than 20 minutes,which can be set.(The gas resource is stable in the range of 80bar-100bar)
It can power the indicator lights and control the furnace when the power goes out,the time is more than or equal 60 minutes.
It’s proximately 320KVA
Temperature control mode
Three zone control temperature independently.
fill with high pressure gas at maximum allowable speed,temperature fluctuation≤±5℃
Positive and negative pressure paraffin removal or PEG integration sintering uniformity:furnace control piece (YC40 or YG6 particles), paraffin, PEG or rubber molding agent, evenly distributed.
The buyer shall provide the furnace control piece and the procedure, and the seller shall confirm it.
Cobalt magnetism: testing cobalt magnetism after finished dewaxing
The temperature uniformity in the furnace is mainly based on the test performance of the furnace control piece.
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.
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.
