Key word:Safe use of hot air circulation oven and four points to note

Hot air circulation oven is made of angle steel, stainless steel and cold plate. The insulation layer is filled with high-density aluminum silicate cotton, high-density aluminum silicate cotton to ensure the insulation of the oven, but also to ensure the safety of users. The heater can be installed on the bottom, top or both sides. Use digital smart meters to control temperature. Hot air circulation oven duct design has two kinds: horizontal air supply and vertical air supply!
Features: Shell made of high quality cold-rolled steel, the surface electrostatic spray process, the appearance of new, durable. Studio made of high quality stainless steel or cold-rolled steel, with high temperature, corrosion resistance, no smoke and so on. The activities of the pull grid, an increase of storage space for the material inside the box with double-glazed glass observation window can be observed at any time the situation is heated studio items. Hot air circulation oven is the use of heating wire compartment heating the object drying equipment.
It is suitable for room temperature higher than 5 ~ 300 ℃ (some high 200 ℃) range of baking, drying, heat treatment, etc., the sensitivity is usually ± 1 ℃. It's a lot of models, but the basic structure is similar, generally by the cabinet, electric heating system and automatic temperature control system consists of three parts. Its use and precautions are summarized as follows:
1. Hot air circulation oven must be placed in the indoor dry and level to prevent vibration and corrosion.
2. Safety of electricity to pay attention to, according to hot air circulation oven power consumption to install a sufficient capacity of the power knife. Choose enough power leads and have a good ground wire.
3. With electric contact mercury thermometer-type thermostat should be two points of the electrical contact thermometer were connected to the roof of the two terminals. Another ordinary mercury thermometer inserted into the exhaust valve, (exhaust valve thermometer is used to check the electrical contact mercury thermometer and observation box actual temperature) to open the exhaust valve hole. Adjust the electrical contact mercury thermometer to the required temperature after the fastening screw on the steel cap, in order to achieve the purpose of constant temperature. However, care must be taken not to rotate the indicator iron outside the scale while adjusting.
4. When all preparations are ready before the sample into the hot air circulation oven, and then connect and turn on the power, the red light indicates that the box has been heated. When the temperature reaches the controlled temperature, the red light is off, the green light is on, and the temperature is started. In order to prevent temperature control failure, it must be taken care of.
