One furnace of steel yields 5 more tons
A steel mill in Shandong used to pour by experience. They left 3 tons of steel in the ladle each time. That was a big waste. We installed a molten metal ladle scale on their ladle turret. Capacity 200 tons, accuracy 0.2% FS. Now operators watch the weight and pour precisely. Residual steel dropped from 3 tons to 0.5 tons per heat. That is 2.5 more tons per heat. 20 heats per day, that is over 10,000 tons per year. The customer said: "This molten metal ladle scale is like a money printer."

Pouring curve to optimize process
The matching indicator draws a real-time weight-versus-time curve. It records the whole pouring process. Engineers can analyze the curve to optimize nozzle opening and sliding gate timing. They find the best pouring parameters. The indicator also has a residual steel alarm. When the weight drops below a set value (e.g., 2 tons), it alerts to prevent slag from entering the casting. All pouring data is saved and can be exported for quality traceability and process improvement. A common question: "Can your molten metal ladle scale survive a rough ladle landing?" Yes, the buffer spring absorbs impacts up to 3 times the static load. Yixing Silvanus Electric Manufacture Co., Ltd. has been making foundry scales since 2007. Choosing us makes every ton of steel count.
