    Safety effect of accident pit of melting furnace in foundry workshop

    Induction smelting furnaces should not start induction melting furnaces without accidentally maintained and dried accident pits . These pits are often referred to as accident pits , which are located below and in front of the intermediate frequency electric furnace . In the event of an accident, they can be used to safely contain any molten metal flowing out of the furnace when it is released or poured out in an emergency. If there is not enough accident pit, the molten metal flowing out will fill the floor of the foundry, endangering workers and damaging the stove, other equipment and structures.

    This free-flowing metal melt can also cause devastating fires and explosions. In order for the accident pit to perform the assigned tasks, they should meet the following requirements: sufficient capacity - each smelting furnace should have an accident pit that can accommodate 150% of its furnace capacity. This scale can accommodate the almost inevitable accumulation of metal solutions that flow out during daily casting. Applicable Structures - Accident pits should be designed and constructed by qualified professionals who should have experience in foundry design and understand your facilities. The pit is constructed of cement and is lined with refractory brickwork. The area immediately below the furnace should be sloped so that the overflow metal melt can be directed away from the furnace and into a deeper holding tank. The area in front of the furnace should be covered with a steel grille. At the bottom of the pit is an inverted steel drum filled with foundry sand for containment, which can later be used to remove the overflow metal melt. With these barrels, the molten metal will be filled with sand and the melt will flow through the inverted steel drum.

    The bottom is injected into the bucket. These barrels can be removed later. Absolutely dry จC the accident pit needs to be completely dry at all times. This is very vigilant because these pits are at low points, and it is easy to accumulate leaking water that is generated during the cleaning operation or that oozes from the ground. The wet pit is the bomb waiting for the explosion! If the molten metal is in contact with the water in the pit, it is likely to be fried.

    When the bomb explodes, the molten metal will fly everywhere. This kind of explosion can cause death and injury. Only dry accident pits can safely contain molten or effluent from the furnace. If the accident pit is wet, you should not start the intermediate frequency electric furnace !

    Water flow system - a water flow system is built inside the pit when it is built, or it can be added later. The moisture flow system helps keep the pits dry. Along with this system, an aluminum water channel or drain is provided at the top of the accident pit. This channel collects any water or liquid that flows down the slope and flows the water away from the overflow to the discharge or sump before the water or liquid flows into the accident pit.

    Careful maintenance จC As with any important safety system, accident pits should be inspected daily and should be free of debris and flammable materials. The pit cover should be free of slag and will

    Other plugs that impede the passage of molten metal. Metal melt from any small overflow should be periodically removed from the accident pit to ensure maintenance

    Sufficient capacity. If you know that your accident pit is the right size, dry, and free of debris, you can start the operation of the intermediate frequency electric furnace , and have confidence that in the event of an emergency, you can safely remove any molten metal from the intermediate frequency electric furnace . Discharge into the accident pit.
