1、Usage for Car Bottom Resistance Electric Furnace for Steel Heating
Mainly used for high chromium, high manganese steel castings, gray cast iron castings, ductile iron castings, rollers, balls, hammer crushers, wear-resistant lining hardening, annealing, aging and heat treatment of various mechanical parts.
1. Heat treatment of large or heavy-duty welding, such as gear blanks, commonly used in automotive and machine tool parts. Other heat treatment applications include industrial steel and aluminum mill applications such as wire annealing, foil annealing and preheating processes such as preheating and reheating.
2. Casting, the most commonly used are large steel and aluminum castings used to make parts.
3. Manufacturing forging processes for automotive, aerospace, oil drilling equipment and other equipment manufacturing parts.
4. Powder metallurgy, which is especially important for changing the unique ability of materials that cannot be produced by normal melting processes.

3、Advantages of the Resistance furnaces
Resistance furnaces are used extensively because of their numerous advantages. Articles can be uniformly heated either by appropriately locating the heating elements along the walls of the furnace chamber or by means of forced circulation of the furnace atmosphere. Automatic control of the power and, consequently, of the temperature conditions in such a furnace is easily implemented. Resistance furnaces are readily mechanized and automated, thus alleviating the work of personnel and facilitating the inclusion of such furnaces in automatic transfer lines. In addition, they are compact. Such furnaces provide a secure environment for various processes.
4、Car Bottom Resistance Furnace selection
High temperature furnace: ≤1250℃
Medium temperature furnace: ≤950℃
Low temperature furnace: ≤650℃
Heating temperature will affect the configuration of heating elements and power, customers can choose the appropriate model according to the actual situation
The following parameters are for reference only, the working size and temperature are produced according to customer requirements
Rated Temperature (℃)
Heat Chamber: When we design the heat chamber, we optimize the insulation grade, thickness and density to fit your particular application. The Chamber construction we used fiber and brick, which have the wonderful performance of thermal storage and good price/performance ratio
Door Design: The furnace door is typically integral to the car or can be fixed to the furnace body and vertically actuated to seal the chamber.The frame of the door is made by section steel and plate which have stronger rigidity. And inside overlapped the fire resistance fiber.The door opening method can be manual side opening or motor lifting
Car Bottom Design: The Car is designed as self-propelled structure, which travelling is through the motor gear driving with the Chain.
Heating System: If heated by electric resistance wire, The heating element is made by high temperature resistance alloy wire, which distributed at side of chamber, furnace door, back-wall, and car floor.
