Reliable Slag Pots for Smelting Success: Engineered for Efficiency & Long-Term Durability
Slag pots are indispensable in metal smelting, designed to withstand extreme temperatures and heavy-duty operations. Both ferrous and non-ferrous metallurgical enterprises produce a large amount of high-temperature liquid slag, and the vast majority of steel furnace manufacturers use slag bags (or slag pots and slag tanks) to load and process slag. Before the birth of welding slag ladle technology, users used a casting slag ladle to treat furnace slag. After the welding slag ladle was born, compared with the casting slag ladle, the slag pot carrier offers significant advantages, including stable quality, low maintenance, good weldability, and high cost-effectiveness.
| Item | Typical Value / Range | Remarks |
| Pot Type | Round (Conical), Oval (Elliptical), Ribbon / Petal Rim | Round is most common; Oval fits tight spaces |
| Rated Slag Capacity | 3 T ~ 60 T+ (Approx. 1.5 ~ 45 m³ volume) | Nominal payload weight |
| Filled Volume | 1.5 m³ ~ 45 m³ | Internal geometric volume when filled to brim |
| Overall Dimensions (LxWxH) | e.g., Ø2500x2000 mm ~ 5840x6004x3900 mm | Length x Width (or Diameter) x Height |
| Empty Pot Weight | 1.5 T ~ 60 T+ | Heavier pots indicate thicker walls/ribs |
| Wall / Rim Thickness | 40 mm ~ 150 mm+ | Thickened rim for impact resistance |
| Material | Cast Steel (e.g., GS16Mn5, ASTM A27), Cast Iron | Steel preferred for high-temp/molten slag |
| Max Slag Temperature | 1,200 °C ~ 1,600 °C+ | Depends on process (EAF vs. BOF) |
| Lifting / Suspension | Lifting Lugs (2 or 4 ears), Trunnions, Lifting Eyes | Lugs are most common for crane handling |
| Tipping / Dumping | Crane Tilt / Self-dumping (via trunnions on carrier) | Often dumped by tilting with crane hooks |
| Design Safety Factor | 5:1 ~ 8:1 (Minimum) | Structural engineering standard for lifting |
| Surface Finish | Rough Cast / Machined Lugs | Lifting points often machined for pins/hooks |
| Service Life | Hundreds to Thousands of Cycles | Depends on slag chemistry and thermal shock |
Starting from the source, Huazhu Mold CAE simulation system is used to simulate and arrange the process, ensuring the quality of the slag tank.
When flipping sand molding, experienced engineers provide on-site guidance, strictly controlling the mesh size of refractory sand, the number of coating applications, the selection of parting surfaces, and the size of each area.
Blow argon on the molten steel to make its composition uniform, improve its quality, and strictly control the appropriate pouring temperature during pouring temperature to ensure the internal quality of the casting.
Using a German GS1000 direct reading spectral analyzer, samples are taken and analyzed in front of, in, and behind the furnace to ensure material quality good.
The use of natural gas heat treatment kiln ensures uniform temperature and ensures the internal quality of the slag tank. Service life is higher than 30% of peers.
During the steelmaking process, the liquid slag reaches high temperatures, and the special slag pot for steelmaking needs to have good high-temperature resistance and withstand long-term operation in a high-temperature environment.
The slag liquid contains many solid particles, and these particles will cause wear on the inner wall of the slag pot. Therefore, the special slag pot for steelmaking needs to have high wear resistance and be able to resist the impact and wear of particles.
With good sealing performance, these industrial furnace spare parts can effectively prevent the leakage of slag liquid and avoid pollution and damage to the environment and equipment.
A large amount of metallurgical slag will be produced in the steelmaking process, and the special slag pot for steelmaking usually has a large capacity, which can meet the large collection and storage needs of slag liquid in the steelmaking process.
Equipped with a slag outlet, a slag discharge valve, a slag shovel, and other equipment, it can conveniently collect and process slag liquid.
Our slag pots are engineered with superior materials and reinforced construction, ensuring unmatched durability and performance even under continuous use. Whether you're in steelmaking, non-ferrous metal production, or waste processing, our slag pots offer precision-cast designs tailored for efficient slag transfer and disposal.
