After long-term use of vacuum sintering furnace, there will be some impurities left in the furnace chamber, we have to maintain it regularly to avoid damage to the equipment. As a supplier of electric furnace R&D, production and sales, the following is the correct maintenance experience shared by HAOYUE.
1. In general, the cleaning operation of the four distribution cabinets of vacuum sintering furnace equipment.
2. If the mesh belt is thimble mesh belt, please use sandpaper etc. to polish the thimble end to prevent the scratch on the cell, if it is beveled angle mesh belt, then bake at low speed in the case of speed 100 to eradicate the organic matter.
3. If the lamp is infected with organic matter, please beware of scrubbing with alcohol cotton or non-woven fabric.
4. The internal cleaning work of the cavity (need to focus on each air hole has no obstruction).
5. Organic row and hot row cleaning work (including plant affairs and equipment, and equipment fume box), please use alcohol to clean the organic matter on the equipment, etc.
6. When disassembling the sealing structure, vacuum system and other parts on the furnace body, please clean them with alcohol or gasoline and after drying, apply vacuum grease and then assemble them on.
7. If the transmission parts are not allowed to limit, control failure, jamming and other phenomena, should immediately stop, do not force the operation, so as not to damage the machine parts.
8. After the vacuum sintering furnace is stopped, the vacuum in the furnace must be maintained at 66.5LPA or less.
9. Vacuum pumps, valves, measuring instruments, thermal instruments, electrical components and other supporting parts must be used, repaired and maintained in accordance with the technical instructions of the product.
In addition, high-temperature heat treatment furnace maintenance operations should be carried out without electricity. If the maintenance is carried out under electrified conditions, it must be carried out by professional maintenance personnel, while ensuring personal and equipment * safety. At the same time, the aluminum plate spot welding machine mechanical transmission parts should be regularly refueled or oil change maintenance.
HAOYUE production and sales of vacuum sintering furnace for many years, has a wealth of experience, so the production of high-temperature vacuum sintering furnace products with excellent performance, can quickly pump the working environment into a vacuum, while quickly to high temperature processing of the required products.
1. As the mold is generally provided by the user, the mold material is basically selected high-purity graphite, its pressure limit of 40MPa, it is recommended that the user use in 30MPa below the safer, before pressurization should calculate the area of the upper and lower punches, and then converted into pressure, the specific formula is as follows: system allows pressurization (tons) = upper or lower punch area × 30MPa If the blind pressurization is not calculated in advance leads to mold, press block The company is not responsible for any damage to the graphite products such as die, briquettes, heating body, insulation screen, etc.
2. Vacuum sintering furnace thermocouple is tungsten rhenium type, used will be brittle, can not touch. If damaged, it should be replaced in time. Its model is W2 type.
3. Winter should pay attention to the circulating water warming problem, otherwise the water pipe bursts easily.
4. The furnace body should keep vacuum after use, because the furnace insulation layer is susceptible to moisture, keep vacuum so that the next vacuum will be faster.
5. High-temperature electric furnace is more complex, it is recommended that the use of a person, a person responsible for the strict implementation of novice training before use, check after use, operation and use to have records of equipment use regulations.
6. This hot pressing furnace can also be used as a vacuum sintering furnace, for vacuum sintering furnace, note that after placing the crucible in the furnace, do not forget to cover the small cover in the middle after covering the insulation screen cover. Otherwise, it is easy to burn the furnace.
7. Before operation, you should clean the glass of the observation window, clean the inner wall of the furnace, observe the water pressure, observe whether the graphite in the furnace is damaged, observe whether the meter display is normal after the power is applied, and test whether the hydraulic system can work normally.
8. During the process of heating up the useful thermocouple, pay attention to the temperature deviation of comparison and infrared, such as temperature deviation, should use the infrared aimer to observe whether the infrared meter is aligned.
9. High-temperature electric furnace should be sent after a year of use of the instrument for calibration.
