When we look at modern industrial production, industrial ovens play an indispensable role. Whether it is electronics, automotive, food, or chemical, pharmaceutical and other industries, it is necessary to use industrial ovens for drying, curing, annealing and other processing of various materials to meet the needs of different production processes. Due to the differences in the production scale, product characteristics and site conditions of different industries and different enterprises, the demand for customization of industrial ovens has become increasingly prominent.
The industrial oven mainly realizes the treatment of materials by means of heat transfer. The modes of heat transfer include convection, radiation and conduction. The LIB oven adopts a convection mode, through the flow of air in the oven, the heat is transferred to the material, so that the water or solvent on the surface of the material is evaporated.
Its main functions, such as drying, can remove water or other volatile components in the material, improve the stability and quality of the material; Curing can make the paint, glue and other chemical reactions under a certain temperature to form a strong protective film or connection layer; Annealing can eliminate the internal stress of metal materials and improve their structure and properties.
Temperature is the key parameter of industrial oven. Different materials and processes have very different temperature requirements. For example, in the electronics industry, the drying of some precision electronic components may only require a low temperature environment of tens of degrees Celsius, and temperature fluctuations need to be controlled within a very small range to avoid damage to the components. In the metal heat treatment industry, high temperature annealing may need to reach thousands of degrees Celsius.
Therefore, the configurable temperature range of the industrial oven must be flexibly adjusted, from low to high temperature can be accurately covered. At the same time, the heating rate and temperature control accuracy are also crucial, some processes require rapid heating to improve production efficiency, while others require slow heating to prevent material damage due to thermal stress. LIB oven has A very wide temperature range, three types of temperature can be selected A:Ambient ~ +250 ℃,B: Ambient ~ +400 ℃,C: Ambient ~ +900 ℃. In order to ensure the uniformity of temperature in the oven, it is necessary to design the layout of heating elements reasonably, install circulating fans and adopt special air duct structures.
The size and capacity of industrial ovens are directly related to their applicability and production efficiency. The size of the internal cavity is determined according to the size, shape and quantity of the workpiece to be processed. For large mechanical parts, such as the curing of automobile engine cylinder block, it needs a large oven chamber to accommodate; For the drying of small electronic chips, relatively small cavities can meet the needs. The overall dimension should consider the space limitation of the production site of the enterprise to ensure that the oven can be reasonably placed.
Heating system is the core component of industrial oven. There are various types of heating elements, common electric heating wire, infrared lamp, gas burner and so on. The heating power needs to be precisely calculated and adjusted according to the volume of the oven, the desired temperature range, and the heating rate. The heating layout also needs to be optimized to ensure that the heat is evenly distributed in the oven to avoid local overheating or undercooling.
The role of the ventilation and circulation system is to ensure the uniform distribution of hot air in the oven, timely discharge of moisture and volatiles, and supplement fresh air. Air volume and wind speed can be adjusted, for some materials that are easy to produce a lot of moisture or volatiles, such as food, chemical raw materials, etc., larger air volume and higher wind speed are needed to quickly exhaust moisture and air exchange; For some materials that are more sensitive to air flow, such as precision instrument components, small and smooth air flow is required. The air duct design should be reasonable, and scientific circulation modes, such as horizontal circulation, vertical circulation or mixed circulation, should be used to enable hot air to fully flow through various parts of the material.
In the electronics industry, industrial ovens are mainly used for the drying, aging and curing of electronic components. In the circuit board production process, the board after the patch needs to be cured in the oven, so that the solder paste is melted and the electronic components are solidly welded to the board. Because the electronic components are sensitive to temperature, the temperature control accuracy of the oven is generally required to be within ±0.5 ° C, and the temperature uniformity is within ±1 ° C. At the same time, in order to avoid damage to electronic components caused by static electricity, the interior of the oven should be made of anti-static materials and equipped with electrostatic removal devices such as ion fans.
In the process of automobile manufacturing, many parts need to be painted and cured, and industrial ovens play an important role. The baking and curing of the car body after painting requires a large industrial oven to accommodate the entire body. The temperature of the oven is generally between 120 ° C and 200 ° C, and the heating rate should be moderate to ensure that the coating can be uniformly cured. The ventilation system should be able to discharge the organic solvent volatiles generated during the painting process in time to prevent explosion accidents.
The food processing industry has extremely high requirements for the material and hygiene of industrial ovens. For example, in the food drying process, such as the production of dried fruits and dried vegetables, the water in fresh ingredients needs to be removed. Because the food is in direct contact with the inside of the oven, the oven must be made of food-grade stainless steel, and there is no sanitary dead angle inside, which is easy to clean and disinfect. The temperature is generally controlled between 40 ° C and 80 ° C to avoid high temperature damage to the nutritional composition and taste of food. The ventilation system should be able to effectively remove moisture, while preventing external dust and impurities from entering the oven.
The customization of industrial ovens can provide accurate, efficient and safe production solutions for various industries. The customization process of LIB industrial oven generally includes the following steps: demand communication, including product characteristics, production process, site conditions, budget, etc.; Scheme design, technical parameters, structural design, control system design, etc., and provide detailed design drawings and quotations; After the review and confirmation of the design scheme; Production and installation; After sales service, LIB provides customers with equipment repair, maintenance, technical training, technical upgrade and other services.
After-sales service includes regular visits to understand the use of equipment and solve problems in a timely manner; Provide equipment maintenance services, in the case of equipment failure, can respond quickly, send professional and technical personnel to repair, to ensure that the equipment is restored to normal operation as soon as possible; Provide customers with equipment maintenance suggestions and maintenance services, such as regular inspection of heating elements, ventilation system, control system and other parts of the operating condition, cleaning oven inside and outside, replacement of wearing parts, etc. According to customers' needs and technological development, we provide customers with technical upgrading services, such as upgrading control system, improving heating system, etc., to improve equipment performance and production efficiency.
