Vlf Trolley Furnace, Trolley Type Electric Resistance Furnace, Fuel-Type Trolley Furnace

Introduction:

The trolley furnace is called a trolley type electric resistance furnace. When it is heated by fuel or gas, it is called a fuel-type trolley

furnace or a gas-type trolley furnace. The trolley furnace is an energy-saving cycle-operated industrial furnace. The trolley that can enter

and exit at the bottom is the main charging carrier, and the heat treatment equipment with heating elements on both sides, the bottom

and the front and the back. The furnace body of the trolley furnace is energy-saving structure and has different furnace masonry

installation methods. There is a WDS composite furnace insulation made up of ultra-light energy-saving bricks and high-purity aluminum

silicate fiber insulation, and there is also a full-fiber lining insulation structure. Anti-collision bricks are commonly used in the furnace

mouth to automatically seal the trolley and the furnace door. Integrated railing, no need for basic installation, can be used on a level

ground.

The purpose of the trolley furnace:

Depending on the design and manufacture, the trolley furnace can be used for 1200C high temperature, 950C medium temperature, 650

low temperature, and even more than 1300C and below 500C for a wider range of heat treatment temperatures. Generally speaking, the

trolley furnace is mainly used for high chromium, high manganese steel castings, gray cast iron parts, rolls, steel balls, crusher hammers

. Wear-resistant lining, auto parts, metal structural parts, carbon steel, welded parts, alloy steel parts quenching, normalizing, tempering,

annealing. Aging and heat treatment of various mechanical parts. It can also be used for drill sintering, catalyst baking, precision mold

baking and other applications.

How the trolley furnace works:

The bottom of the trolley furnace is a movable trolley for loading workpieces. The load carrying capacity is stronger than other industrial

furnaces, and it can load large, heavy workpieces for heat treatment. Before heating, the loading trolley is first opened outside the furnace

, and can be loaded by the workshop or by various means. The heat treatment workpiece can be placed directly on the trolley that has the

furnace floor installed, and then the electrically controlled trolley can send the workpiece. The furnace is automatically sealed in the

furnace, and the heat treatment process is fully performed by the temperature control system. After the heat treatment, the furnace can be

cooled or directly pulled out of the furnace, and the heat-treated workpiece is subjected to subsequent treatment.

Classification of trolley furnaces:

1. Trolley furnaces are classified according to heating methods: trolley type electric resistance furnace, fuel trolley type furnace, and gas

trolley type furnace.

2. The trolley furnace is classified according to the heat treatment temperature that can be achieved: high temperature trolley furnace (0-

1200), medium temperature trolley furnace (0-950), low temperature trolley furnace (0-650)

3. Trolley furnaces are classified according to process requirements: trolley-type annealing furnace, trolley type

Due to the high-precision automatic temperature control technology of the microcomputer program and the ceramic fiber high-pressure

module lining, the trolley type quenching furnace can realize rapid temperature rise and high-precision temperature control. In addition,

the furnace body and the trolley pass the self-sealing mechanism to reduce the heat convection loss of the trolley furnace, and realize the

high-efficiency insulation performance of the trolley furnace. The quenching trolley furnace adopts multi-zone heating, and the high-

average temperature technology realizes uniform heat transmission of the quenching and heating workpiece, so that the quality of the

quenching furnace heat treatment is further improved.

The trolley type vacuum furnace adopts non-standard design due to the special requirements of the user’s products. The furnace mainly

consists of furnace body, furnace lining, furnace tank and pre-vacuum device, furnace car, furnace drive mechanism, electric heating

device, temperature control and The main part of the recording system is composed.
