Electric furnace resistance board

    Electric furnace resistance board is also called electric furnace board, electric heating board and electric heating board. Commonly used are cast aluminum electric heating plates and iron-chromium aluminum alloy resistance plates, nickel-chromium alloy resistance plates. Widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemicals, rubber, petroleum and other equipment.

Resistance board

    The cast aluminum electric heating plate is a metal casting heater which uses a tubular electric heating element as a heating element, and is bent and formed into a mold, and is cast into various shapes by a high-quality metal alloy material as a casing, and has a round shape, a flat plate, a right angle type, Air-cooled, water-cooled and other shaped parts. After finishing, it can be closely adhered to the heated body. The surface load of cast aluminum can reach 2.5-3w/cm2, and the maximum working temperature is within 320 °C. The surface load of cast copper can reach 3.5-5.0w/cm2, and the maximum working temperature is 600. Between -700 ° C; cast iron surface load can reach 4.5-6.0w / cm2, the maximum working temperature is 700 ° C. 

 

The metal casting heater is a high-efficiency heat-segmented heater with excellent thermal conductivity of the metal alloy, ensuring uniform temperature on the hot surface and eliminating hot spots and cold spots in the equipment. It has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance and magnetic field resistance. The external heat dissipating surface is added to the heat preservation device, and the inner heat dissipating surface is sintered with infrared rays, thereby saving 35% of electricity consumption.

Cast aluminum electric heating plate

    Iron-chromium-aluminum alloy resistance plate, nickel-chromium alloy resistance plate is made of iron-chromium-aluminum/nickel-chromium alloy plate as the base material, and is often processed into a corrugated shape by sheet metal cold working or hot heat processing. It has high power and needs heat treatment to eliminate stress after tanning.
