Basic safety requirements for high-temperature molten metal operations (2)

 　　one

　　Safety requirements for vehicles transporting molten metal

　　✔ The transportation equipment for molten metal should have measures to withstand high temperatures and prevent splashing, with complete and reliable braking measures.

　　✔ Transport vehicles are not allowed to stay under gas, oxygen, hydrogen pipelines, cable corridors, or areas with flammable and explosive substances; Insulation measures should be taken for pipelines crossing over roads.

　　✔ Transport vehicles undergo regular safety inspections, inspections, repairs, and maintenance (such as maintenance of refractory materials for mixed rail vehicles).

　　✔ The driving speed of heavy tank cars (including mixed iron cars) for transporting molten iron should not exceed 10km/h, and should not exceed 5km/h under the furnace or inside the workshop.

　　Casting safety of molten metal

　　✔ Before each molten metal casting in the insulation furnace, it is necessary to check and confirm the integrity of the flow hole bricks and flow grooves, and ensure that the overlap between the flow holes and flow grooves is tightly blocked, control the flow rate of the flow holes, and prevent slot leakage.

　　✔ When pouring molten metal, take safety precautions to prevent it from splashing or splashing and injuring people.

　　✔ The casting machine should be equipped with an emergency water source to ensure that the molten metal in the casting machine's flow channel is completely cooled in the event of an unexpected water or power outage.

　　Management of molten metal operation site

　　✔ Meeting rooms, activity rooms, rest rooms, changing rooms, and other densely populated areas should be set up in safe locations, and should not be located at the lower part of the ventilation platform or the casting yard. Their doors and windows should avoid iron and slag openings; It shall not be set within the range of influence of high-temperature liquid metal lifting.

　　✔ Equipment, wires and cables, pipelines, and buildings (structures) within the molten metal operation area should be insulated and protected.

　　✔ Buildings (structures) that withstand heavy loads, high temperature radiation, hot slag splashes, and other hazards should undergo regular structural safety assessments.
