Description: Electric Heating oven Application: This type of drying box adopts high-efficiency and low energy consumption far infrared heating technology, used for welding preheating, drying of industrial welding ,such as in chemical industry, ship building industry .And it can be also used in stainless steel heat treatment and general dehydration. Structure brief introduction: It is made of shell steel plate; surface is covered with lacquer, The working chamber is made of stainless steel plate, it is filled up with aluminum silicate fiber between interlayer so that can do heat preservation. So insulation performance is good. Carbonized silicon is divided into two groups, separately placed in the bottom and top of the working chamber,and each has a switch to control circuit’s on-off , and equipped with indicator light, when the light is on shows that circuit is on , on the contrary, the light is off ,the circuit is off. Using roast copper thermocouple to make temperature-sensing element, temperature controller (hereinafter referred to as instrument)to measure temperature. And automatic temperature control. Sensitive and reliable. Easy operation. This box is attached with 5 - 60 minutes timing devices which can be adjusted, when reach the setting time, it can auto power-off,stop working.
