How does the Ruideer vacuum sintering furnace operate efficiently

Ruideer sintering furnace is suitable for, but not limited to,

Vacuum dewaxing sintering and pressure sintering of cemented carbide products, high magnetic products, cermet products, ceramic products and other powder metallurgy products.

The matching sealing electrode for sintering furnace

• The sealing electrode is made of pure copper, which can be cooled by cooling water. The external end is connected to a low-voltage water-cooled cable (or dry cable, copper bar), and the internal end is connected to a graphite heating element.

• Each heating area has a separate grounding current monitoring device. When the grounding current is greater than 30A, the system will generate a grounding alarm for the corresponding area; when the grounding current is greater than 50A, the grounding current circuit breaker will be disconnected and the system will stop heating.

• Each electrode is equipped with a separate cooling water flow switch. When the flow switch generates an alarm, the system stops heating.

How is the dewaxing system working for sintering furnace?

Dewaxing systems can be custom designed for customers. Whether customers use PEG, parafin or other forming agents, they can be effectively removed and collected by condensation. Customers can choose positive pressure hydrogen dewaxing or negative pressure argon dewaxing according to the process. The dewaxing system adopts directional dewaxing, and uses air flow to control the pressure difference inside and outside the graphite liner, so that the molding agent enters the dewaxing system through the established pipeline to condense.

How is the Rapid cooling system operating in sintering furnace?

The fast cooling of the pressurized sintering furnace is divided into two stages. The first stage is to cool down naturally under the pressure environment, and the heat preservation door is closed; the second stage is to open the heat preservation door after reaching the set temperature to make the high pressure in the furnace. The argon gas passes through the radiator on the furnace door to quickly take away heat. When the furnace top furnace temperature or the furnace door radiator temperature reaches the upper limit, the heat preservation door is closed again, and the furnace top furnace temperature or the furnace door radiator temperature drops accordingly. When the temperature of the top furnace or the radiator of the furnace door drops, when the temperature is lower, the insulation door is opened again. After several cycles, the temperature of the furnace top or the radiator of the furnace door no longer reaches the upper temperature limit, and the insulation door is always open.

How to prepare on-site furnace instalation for the customer?

When the sintering furnace is produced, it will be checked internally at the RDE factory. After passing the acceptance, the product will be decomposed and packaged and transported to the user's site for installation. RDE will provide a detailed equipment dimension interface and floor plan, and users can make preparations before installation based on this information.

• The ground on which the equipment is installed must be flat and meet the bearing capacity requirements, and the height of the plant must meet the equipment requirements.

• Prepare cooling water lines, process gas lines, high-pressure argon gas lines, compressed air lines, and power supply cables for equipment.

• Prepare the hoisting and lifting equipment for the furnace

• Prepare compressed air and backup air source (6bar~7bar).

• The circulating cooling water must be pure water with no impurities and no chemicals. The temperature, pressure and flow of the cooling water must meet the requirements.

• Install indoor flammable gas alarms.

• Prepare a vacuum cleaner and vacuum grease.

• Prepare vacuum pump oil.

How to charge products into the sintering furnace?

• Make sure there is no high pressure, no vacuum, and no flammable gas in the furnace.

• If there is high pressure in the furnace, use the "Release" function in the manual mode of the function to release the gas until the pressure is equal to atmospheric pressure.

• If there is a vacuum in the furnace, use the "Low-pressure argon" function in the manual mode of the function to fill the furnace to equilibrium with atmospheric pressure.

• If there is flammable gas in the furnace, use the "Hydrogen Exhaust" function to remove the flammable gas from the furnace.

• Switch the operation mode to "full manual state", press and hold the two buttons to open the door, and the system will open the door.

• The latch will be retracted, and the clamping part will start to rotate clockwise to open. When the clamping part is in place, the oven door will open.

• When the furnace door is opened to the working range of the proximity switch sensor, the furnace door stops and the furnace door opening action is completed.

• Place the prepared product on the material-bearing bottom plate, and use the charging trolley to push the material-bearing bottom plate into the inner tank. The overall seal of the liner.

• Make sure there are no other debris in the furnace.

• Make sure the furnace chamber is clean.

• Make sure the oven door seal is intact and clean.

• Make sure the front and rear insulated doors are open.

• Press and hold the two buttons to close the door, and the system will close the door.

• After the furnace door is closed in place, the clamping part starts to rotate counterclockwise to close. When the clamping part is closed in place, the latch will open and the furnace door closing action is completed.
