[0002] In converter production systems, the feeding pipes require frequent maintenance and welding due to long-term material erosion and equipment vibration. Because the converter platforms use a grid structure, high-temperature welding slag can easily penetrate the grid holes and fall onto the platforms or equipment below, causing the following problems: Fire hazard: Welding slag temperatures can reach over 800℃, igniting oil, cables, or flammable materials below. Personnel injury: Burns to workers below, causing safety accidents. Equipment damage: Welding slag splashes onto the surface of precision equipment, causing damage. Inefficient maintenance: Requires dedicated personnel to clean the welding slag, extending downtime. Traditional protection methods involve laying fireproof cloth, but these have drawbacks such as poor adhesion, easy displacement, and limited flame-retardant effect.
[0003] In view of the above factors, a slag protection receiving device for converter feeding pipeline maintenance is provided, which is a receiving device to prevent slag splashing during the welding maintenance of converter feeding pipeline, and is especially suitable for converter platform environment with multi-layer grid plate structure.
