RX3-45-9 box-type electric heating furnace is a periodic-operation resistance heating equipment, suitable for normalizing, quenching, annealing, tempering and other heat treatment processes of metal parts in natural atmosphere or protective atmosphere. The equipment has a rated power of 45kW and a maximum working temperature of 950°C. The furnace chamber size can be customized according to user requirements.
Rated voltage: 380V, three-phase, 50Hz; Rated power: 45kW; Maximum working temperature: 950°C; Common working temperature: 850°C; Furnace chamber size (L×W×H): 900×450×450mm (customizable); Heating elements: resistance wire or resistance strip, arranged on both sides and bottom of the furnace chamber; Temperature control method: PID intelligent adjustment, temperature control accuracy ±1°C; Furnace lining material: high-alumina refractory bricks and aluminum silicate fiber cotton, with good insulation performance; Overall dimensions and weight: determined according to specific configuration.
The equipment is based on the Joule heating effect. Current passes through resistance heating elements to generate heat, which heats the workpiece by radiation and convection. The furnace temperature is detected in real time by thermocouples and automatically adjusted with temperature control instruments to ensure stable execution of the process curve.
The furnace body adopts a steel plate welded structure, lined with refractory materials and insulation layers. The furnace door is equipped with an observation hole and manual or automatic pressing device. The heating elements are installed on both sides and bottom of the furnace chamber for easy replacement. The temperature control system adopts a digital display regulator with over-temperature alarm and power-off protection functions.
Suitable for small-batch or medium-batch heat treatment production in machinery manufacturing, automotive parts, hardware tools, molds and other industries, and can also be used for heat treatment tests in laboratories and scientific research institutions.
The equipment should be installed in a dry, ventilated environment free of corrosive gases. The power supply must be equipped with a circuit breaker matching the power and grounding protection. Please read the product manual before use and operate according to the procedures.
