Safe use of hot air circulation oven and four key points for attention

The hot air circulation oven is composed of angle steel, stainless steel plate and cold steel plate. The insulation layer is filled with high-density aluminum silicate cotton. High-density aluminum silicate cotton ensures the insulation of the drying box and ensures the safety of the user. Heaters can be installed at the bottom, top or sides. Use digital display intelligent meter to control the temperature. There are two kinds of hot air circulation oven wind channel design: horizontal wind and vertical wind!

Product characteristics: The shell is made of high quality cold rolled steel plate, the surface adopts electrostatic injection molding technology, the appearance is novel, strong and durable. The studio is made of high quality stainless steel or cold-rolled steel, which has the advantages of high temperature, corrosion resistance, and no black smoke. The active pull-and-pull mesh frame adds a double-layer tempered glass observation window to the middle of the storage space door of the box material, and the heated items in the working room can be observed at any time. A hot air circulation oven is a device that uses an electric wire insulation layer to heat an object to dry.

It is suitable for baking, drying, and heat treatment in the range of 5 to 300 °C(some 200 °C) higher than room temperature, and the sensitivity is usually ± 1 °C. It has many models, but its basic structure is similar. It is generally composed of three parts: a box body, an electric heat system, and an automatic temperature control system. Its use and attention are summarized as follows:

1. The hot air circulation oven must be placed in the dry and horizontal areas of the room to prevent vibration and corrosion.
2. Safety of electricity should be noted, according to the hot air cycle oven power consumption sufficient capacity installed power gate knife. Select enough power wires and have good grounding lines.
3. A Mercury thermometer with electrical contact shall be attached to two connecting posts at the top of the box by two wires of the electric contact thermometer. Another common mercury thermometer is inserted into the exhaust valve.(The thermometer in the exhaust valve is used to proofread the electric contact mercury thermometer and to observe the actual temperature in the box) to open the vent valve hole. Adjust the mercury thermometer contact to the desired temperature and tighten the screw on the steel cap to achieve constant temperature. However, care must be taken not to rotate the indicator iron outside the scale when adjusting.
4. When all preparations are ready, the test product can be placed in a hot air circulation oven, and then the power supply is connected and turned on. The red indicator light indicates that the box is heated. When the temperature reaches the controlled temperature, the red light goes out and the green light turns on and the temperature begins to change. In order to prevent temperature failure, it is also necessary
