The oven shell is generally made of thin steel plate, the surface is painted, and the studio is made of high-quality structural steel plate. The shell and the working chamber are filled with aluminum silicate fibers. The heater is mounted on the bottom and can also be mounted on the top or on both sides. The temperature control instrument uses a digital smart meter and PID adjustment: it is equipped with a 999.99-hour time controller and connected with an alarm device. Make the operation of the oven easier, faster and more efficient.
Structural features of electric heating oven
1.Overview of electric heating oven
The oven adopts the new energy-saving and environmentally friendly heating technology that is promoted by the state. The electric heating tube is heated by the power supply to generate a heat source. When it is absorbed by the heated object, it can be directly converted into heat energy, so as to obtain a fast drying effect, shorten the production cycle and save energy Improving product quality and other purposes.
2. Electric heating oven structure
The oven body is made of angle steel and thin steel plate. Glass case is filled and insulated between the shell and working room. The heating system is installed at the top of the working room. Horizontal circulation ventilation makes the temperature in the box more uniform. This type of drying box can effectively avoid the gradient temperature difference and temperature overshoot existing in the working room, and can improve the temperature uniformity in the working room.
3. Electric heating oven temperature control
Intelligent program temperature controller is used for temperature control, PID parameter self-tuning, solid state relay power adjustment, non-contact continuous adjustment, automatic completion of the entire drying process, which can meet the requirements of any curing curve, easy operation and reliable performance. Equipped with a thermosensitive element probe for automatic constant temperature control. Temperature control precision is sensitive, room temperature ~ 300 ℃ can be selected and set arbitrarily. The temperature in the studio can be read directly from the meter. Constant temperature time can reach 999.99H.
4. Electric heating oven heating principle
The heating tube is heated by electric energy, and the air is sent by the motor through the air duct to make the temperature inside the oven uniform. The air supply mode is divided into vertical circulation air supply and horizontal circulation air supply. Through different air supply methods, the heating is more reasonable and uniform.
5. Working principle of electric heating oven:
The temperature is controlled through the connection between the digital display instrument and the temperature sensor. The hot air circulation supply method is adopted. The hot air circulation system is divided into horizontal and vertical. The air source is precisely calculated, the air source is driven by the air supply motor to drive the wind wheel through the electric heater, send the hot air to the air duct, and then enter the oven studio, and the used air is sucked into the air duct to become the air source and recirculated and heated. Can effectively improve temperature uniformity. If the door is opened and closed during use, the supply air circulation system can quickly restore the operating state temperature value.
Ovens can be divided into programmable ovens, precision ovens, nitrogen-filled ovens, vacuum ovens, explosion-proof ovens, electric blast drying ovens, and hot air circulation ovens. Fang Pan is suitable for components that require drying and heating in various industries.

Ovens can be divided into two types: horizontal oven and vertical oven.
Ovens are distinguished by rated temperature and can be generally divided into:
100℃以下，一般用于电气产品老化，普通料件的缓速干燥，部分食品原料、塑料等产品的干燥用。 Low temperature oven: Below 100 ℃, it is generally used for aging of electrical products, slow drying of ordinary materials, and drying of some food materials, plastics and other products.
100-250℃，这是常见的使用温度，用于大多数料件的水分干燥、涂层固化、加温、加热、保温等。 Oven at normal temperature: 100-250 ℃, this is a common use temperature, used for moisture drying, coating curing, heating, heating and heat preservation of most materials.
250-400℃，高温干燥特种材料、工件加温安装、材料高温试验、化工原料的反应处理等。 High-temperature oven: 250-400 ℃, high-temperature drying of special materials, heating installation of workpieces, high-temperature testing of materials, reaction treatment of chemical raw materials, etc.
400-600℃，更高的工作温度，高温干燥特种材料、工件加温热处理、材料高温试验等 Ultra-high temperature oven: 400-600 ° C, higher working temperature, high-temperature drying of special materials, heat treatment of workpiece heating, high-temperature test of materials, etc.
Classification of air supply methods for electric heating ovens and their applicability: The air supply methods of hot air circulation ovens are divided into horizontal air supply and vertical air supply.
适用于需放置在托盘中烘烤的物件；水品送风的热风是由工作室两边吹出的，所以可以沐浴在托盘中的物件！ 1. Horizontal air supply: suitable for objects to be placed in the tray for baking; hot air for water supply is blown from both sides of the studio, so objects that can be bathed in the tray! The baking effect will be good. On the contrary, it is not suitable to use the vertical air supply for the objects baked in the tray. The vertical air supply hot air is blown out from top to bottom, it will block the hot air, so that the hot air will not bathe the lower layers. It will be bad!
适用于烘烤放置在网架上的物件，垂直送风热风是由上而下吹出，由于是网架，真个上下流通性会很好，使得热风可完全沐浴在物件上！ 2. Vertical air supply: It is suitable for baking the objects placed on the grid. The hot air of vertical air supply is blown from top to bottom. Since it is a grid, the upper and lower circulation will be very good, so that the hot air can completely bathe the object on! Of course, the objects placed on the grid can also be used for horizontal air supply, depending on the characteristics of the objects themselves!
Use an electric heating oven safely:
1. There must be a certain amount of space for the oven, and there must be a certain distance from the wall on all sides. It is recommended to have more than 2M.
2. The baking items should not be arranged too densely. Do not place items on the bottom of the oven (radiating plate) to avoid affecting the hot air circulation.
3. It is forbidden to compensate for flammable, explosive items and volatile and corrosive items.
4. Turn off the power supply after the baking is completed, and then open the studio door. Remember that you cannot directly touch the baking items with your hands. Use special tools or wear insulated gloves to take out the baking items to avoid burns.
5. When using an oven, the temperature cannot exceed the operating temperature of the oven. Generally, the oven is below 250 degrees.
6. Customers with special requirements can purchase special ovens, such as explosion-proof ovens, high-temperature ovens, etc.
Precautions for using electric heating oven
An oven is a device that uses an electric heating wire to heat and dry an object. It is suitable for baking, drying, heat treatment, etc. in the range of 5 to 300 ° C (200 ° C higher) than room temperature. The sensitivity is usually ± 1 ° C. There are many types of ovens, but the basic structure is similar. Generally, the oven, electric heating system and automatic temperature control system
