The full name of the trolley furnace is a trolley-type resistance furnace. When fuel oil or gas is used as the heating method, it is called a fuel trolley furnace or a gas trolley furnace. Trolley furnace is a national standard energy-saving period-operating industrial furnace. The main loading carrier is a trolley that can enter and exit at the bottom, and heat treatment equipment with heating elements on both sides, bottom and front and rear. The furnace body of the trolley furnace is an energy-saving structure and has different furnace masonry installation methods. There are WDS composite furnace insulation using a combination of ultra-lightweight energy-saving bricks and high-purity aluminum silicate fiber insulation, as well as a full-fiber furnace lining insulation structure. The furnace mouth generally adopts anti-impact bricks, and the trolley and furnace door are automatically sealed. Integrated connecting rail, without foundation installation, can be used on horizontal ground.
Depending on the design and manufacture, the trolley furnace can be used for high temperature of 1200 ℃, medium temperature of 950 ℃, low temperature of 650 ℃, and can even reach a wider range of heat treatment temperature above 1300 ℃ and below 500 ℃. Generally speaking, the trolley furnace is mainly used for high chromium, high manganese steel castings, gray iron castings, ductile iron castings, rolls, steel balls, crusher hammers, wear-resistant linings, automotive parts, metal structural parts, carbon steel , Welding, alloy steel parts quenching, normalizing, annealing, aging and heat treatment of various mechanical parts. Can also be used for drill sintering, catalyst baking, precision mold baking and other applications.
Way of working:
The bottom of the trolley furnace is a movable trolley for loading workpieces. The carrying capacity is stronger than other industrial furnaces, and it can load large and heavy workpieces for heat treatment. Before heating, the loading trolley is out of the furnace. It can be hoisted in the workshop or loaded in various ways. The heat-treated workpiece can be directly placed on the trolley with the furnace floor installed, and then the electrically controlled trolley can send the workpiece. It enters the furnace and is sealed automatically, and then the temperature control system performs the heat treatment process automatically. After the heat treatment, it can be cooled with the furnace or the trolley can be directly out of the furnace, and the heat-treated workpiece is sent to the forging equipment for processing.
Can be customized according to user requirements up to 20000kw trolley electric heating heat treatment furnace.
