The speciality of vacuum heat treatment is the combination of two professional skills of vacuum technology and heat treatment technology, which can effectively improve the quality of composite materials and promote the continuous improvement of industrial production technology in China. When the metal composite material is heated in the steam furnace, it will react exothermicly with the chemical substances such as co2, water vapor and co2 in the vapor of the county. The converted compound will damage the quality of the composite material and lead to the deterioration of the quality of the composite material. . The vacuum heat treatment furnace can solve this difficulty very well. In the process of heating the metal composite material, the metal composite material is in the geographical environment of the complete mechanical pump, and the heat treatment process is carried out under the contact of different external geographical environments. Thereby effectively preventing the slag from penetrating and improving the quality of the composite material.
2 Characteristics analysis of new type quick-change furnace metal composite heat treatment furnace
3.2 Unusual air-cooled machine equipment setting Because the vacuum heat treatment furnace must perform effective heat treatment on the composite material under the condition of mechanical pump, the vacuum heat treatment furnace must effectively reduce all parts of the treatment furnace during the application process. Temperature, to ensure the safety of mechanical equipment and mechanical equipment without problems. At present, vacuum curing equipment in China is mostly used for air-cooling equipment to reduce the temperature of parts, so that the mechanical pump seal of the vacuum heat treatment furnace is not easy to overheat deformation or damage, ensuring no problem operation of the vacuum heat treatment furnace, and improving the vacuum heat treatment furnace. The service life.
4.3 High-quality sealing and high-quality sealing is an important feature of the vacuum heat treatment furnace. Only by ensuring the sealing performance of the treatment furnace can the contact between the composite material and the external air oxidizing compound be reduced, thereby effectively improving the quality of the composite material. In the design process of the scheme, in order to ensure the characteristics of the mechanical pump of the vacuum heat treatment furnace, the vacuum heat treatment furnace often undergoes a harsh processing production process, such as airtight welding of the furnace wall, and there is no vacuum heat treatment furnace wall opening to reduce the vapor body. Infiltration into the opportunity. Together, other prefabricated components of the vacuum heat treatment furnace wall are also subjected to severe sealing treatment to improve the overall tightness of the vacuum heat treatment furnace.
3.2 High efficiency Insulation materials and heating materials Because the internal software environment of the vacuum heat treatment furnace is not easy to penetrate into the air-oxidized acetylene gas such as co2, it can effectively improve the heating efficiency of the composite material and the overall quality and quality. This difficulty, the vacuum heat treatment furnace can not understand the difficulty of air oxidation when selecting the heating and thermal insulation materials, and can pay more attention to the high heating efficiency and thermal insulation effect of the raw materials. Generally speaking, the thermal insulation materials and heating materials used in the vacuum heat treatment furnace are tantalum, tungsten, molybdenum and high-purity graphite, although such materials are likely to cause redox reactions under gas conditions, but due to the characteristics of the vacuum heat treatment furnace To promote such thermal insulation materials and heating materials in the actual production process can fully mobilize the quality effect.
2.9 Automated Control Operation During the operation of the vacuum heat treatment furnace, it is necessary to go through multiple postures to carry out the heat treatment of the composite material. Under the manual customer service telephone operation process, it is prone to operational errors, resulting in disorder of the production process and the quality of the composite material. If it is reduced, then it must be ensured that the mechanical pump processing furnace is continuous and orderly. Therefore, another feature of the vacuum heat treatment furnace is that it has an efficient automatic control production and processing method. The automation technology of the vacuum heat treatment furnace is very high. According to the operation of the relevant process, it can ensure that all the postures in the process of the vacuum heating furnace are carried out within 185 seconds, and it is not easy to appear any carelessness, thus effectively ensuring the overall vacuum heating furnace. High operating efficiency, ensuring the quality of warming compounds.
2.2 Unusual low-voltage high-current scheme design Generally speaking, the extracellular fluid of the vacuum heat treatment furnace is not equipped with acetylene gas. During the working process of the vacuum heat treatment furnace, if the internal working frequency of the vessel is too large, the energized conductor is allowed to be The relevant industrial electric furnace is damaged during the charging and discharging process, which causes the mechanical equipment to be unusable. In response to this difficulty, vacuum heat treatment furnaces are designed with low voltage and high current capacity to avoid mechanical damage caused by the charging and discharging process. Together, the industrial electric furnace structure will also use the necessary precautions to avoid the problems of glow discharge or arc charging and discharging.
3 Common vacuum heat treatment furnace product types
4.3 External fast-heating vacuum heat treatment furnace The external quick-heating vacuum heating furnace is the first vacuum heating furnace product. The structure is simple and objective, and the lack of air-cooled machinery and equipment causes the working temperature of the external fast-heating vacuum heating furnace to not exceed High, otherwise it will be harmful to the composition of the hot blast stove itself. In the actual operation process, the external fast-heating hot blast stove can avoid the external acetylene gas registration and participate in the heat treatment work, and can basically guarantee the quality of the heating material. It is a widely used mechanical pump heat treatment equipment.
3.2 The internal fire type vacuum heat treatment furnace is a vacuum heat treatment furnace. It is a vacuum heat treatment mechanical equipment with rapid development trend. The type of internal fire type vacuum heat treatment furnace is various, the quantity is large, and it is heated by the electric resistance wire, and the mechanical equipment for temperature reduction treatment is used, and it is often used in the production processes such as heat treatment, quenching and tempering treatment, calcination and heat treatment, and The expected effect is very good. The working environment of the internal fire type vacuum heat treatment furnace is more stable and superior than the external fast heat type vacuum heat treatment furnace, and can effectively ensure the smooth development of the heat treatment work of the compound, and the operation steps of the fully automatic control also greatly improve the vacuum heat treatment furnace. The work execution force is the current development prospects** spacious vacuum heat treatment machinery.
4 Development direction of vacuum heat treatment furnace With the continuous improvement of China's innovation and technology level and the increasing exchange and communication between the world, the development trend of vacuum heat treatment furnaces in China has also been greatly improved. The production and processing requirements of the processing industry in China have promoted the quality of production and processing of industrial products in China, and the market demand for industrial products in China has been increasing. However, the development trend of vacuum heat treatment machinery and equipment is still equipped with the necessary difficulties and deficiencies.
