Lift Furnace

Technical overview

Designed around the complete thermal process.

Lift Furnace is a HuanYu lift furnaces system for ceramic sintering, glass melting, materials research, batch thermal processing. Published configuration references include Configuration specific and Vacuum-capable. Final selection depends on the material, workload, process window and selected configuration.

Key technical facts

• +Temperature reference: Configuration specific
• +Environment reference: Vacuum-capable
• +First, the lifting furnace product introduction: KH series electric furnace operating temperature is optional from 800 degrees to 1800 degrees, furnace size is customized according to customer requirements, the furnace liner uses vacuum forming high-purity alumina ceramic fiber blanket, heat storage is small, thermal insulation and energy saving effect is better, and the overall weight of the electric furnace is greatly reduced. The furnace shell has a double-layer air-cooled structure, ensuring that the surface temperature of the furnace shell is close to room temperature. The temperature control system adopts intelligent instruments with high industrial accuracy, PID adjustment, multi-stage programmable temperature rise curve, high degree of automation, electric lifting furnace doors, large loading capacity, high production efficiency, especially suitable for heat treatment of small and medium-sized machines, and adopts the loading and unloading method, which is convenient for loading and unloading and has good operating conditions. II. Overview of the lifting furnace structure: 1. This series of lifting furnaces is divided into four parts: furnace body, movable furnace table, lifting system, and control system. 2. The furnace shell has sectional steel, the steel plate is welded into a four-square box with the furnace opening facing downward. The lower part is welded into a bracket by channel steel, the high-temperature furnace lining is masonry in the middle, the insulation layer is made of high-temperature resistant ceramic fiberboard, the furnace lining is carved with assembled ceramic fiber to form the plate, and there is a reinforced support structure to enhance the top strength of the furnace. The U-shaped heating elements are evenly distributed around the furnace to achieve uniform furnace temperature. 3. Movable stovetop: The movable stovetop is placed on the rails of the lifting frame, and after the rails of the lifting frame are lowered, they are connected to the tracks outside the furnace. The movable stovetop can be manually pulled out of the stove. The side of the stovetop is equipped with a stovetop positioning bolt,
• +The furnace is stable during lifting. 4. Lifting system: Manual hydraulic lifting. 5. Control system: This furnace is equipped with a temperature control system. The temperature control system consists of thermocouples, compensation wires, temperature control instruments, controlled silicon, etc. The temperature control process is automatically adjusted by PID to control the furnace temperature, and the stable fluctuation is small. III. Detailed model specifications of the lifting furnace: 100 * 100 * 100/200 * 200 * 200/300 * 300 * 300/400 * 400 * 400/500 * 500 * 500 Various specifications can be customized. IV. Requirements for installation and wiring of equipment and installation of electric furnace: 1. Before the power supply is connected to the equipment, a distribution box (provided by the user) shall be set up. The main switch, fuse and good grounding shall be installed in the distribution box. The power supply shall be connected in a three-phase five-wire system. The installation capacity shall not be less than 2 times the rated power. 2. When the equipment is fixed, the distance from the wall to the left, right and back must be greater than 600 mm for easy maintenance and furnace door opening. 3. The surrounding environment of the equipment requires the site to be flat, free of corrosive gases, dust, and away from flammable and explosive materials. 4. The equipment should be avoided in the vibration and overheating environment, so as not to affect the normal operation of the control instrument. The ambient temperature is allowed to be -10 ~ 40 ℃, and the relative humidity is lower than RH85%. When connecting to the power supply, it should be operated by the electrician, and the wiring should be aligned according to the electrical wiring diagram, otherwise it will affect the normal operation of the equipment.
• +Danger of damage to electrical components and electric shock. After the wiring is carefully checked, the power can be connected, and the equipment must be grounded and protected. 5. This electric furnace does not require a special foundation, and can be installed as follows by simply leveling in place. (1.) Open the packing box of the electric stove and check whether the accessories of the electric stove are complete against the shipping list. (2). Pull the stopper brick from the top of the furnace and place the original into the stopper brick. Install the asbestos head and tighten the bolts at the bottom of the aluminum spraying section at the cold end of the original so that the components will not slide down when inserted into the furnace (the above process should not be too hard, because the components are brittle and easy to break). (3). Remove the small wooden block at the cold end of the component, tighten the plug brick with both hands and insert it vertically into the brick hole on the top of the furnace. Note that there must be no collision or hard insertion when inserting, and note that the hot end of the component cannot touch the furnace brick and cannot exceed the furnace brick protective ribs. (4). Fill the refractory fiber around and in the gap between the plug bricks to reduce heat loss. Connect the copper foil tape, iron chuck and transformer busbar. Note that the copper foil tape and components must not have internal stresses and should be in a natural state. (5). Insert the thermocouple into the hole and connect all the wires according to the wiring diagram.
