Gansu Hailin Zhongke Science & Technology Co., Ltd.
A cross-province campaign: transfer filtration plus furnace cleaning, both passed re-inspection — followed by a quench-oil filtration contract.
Background
Both the quench tank and the salt tank suffered from sludge build-up, and the plant could not afford a long shutdown. We transferred the melt from the quench tank through a dedicated filter into the salt tank and returned it to service, avoiding a complete salt change.
What we did
Sludge removed from the system
Equipment arrived and was installed on 12 January; piping and cabling followed on 13 January with four people on site.
On 14 January the melt was filtered from the quench tank into the salt tank, with three operators sampling every four hours.
From 15 to 18 January the furnace interior was cleaned while filtration continued.
What changed
- Samples taken by the customer on 15 and 16 January both passed, confirmed jointly on site.
- The quench tank was purified without a salt change, saving both the cost of new salt and downtime.
- In September 2026 the customer added quench-oil filtration and oil-tank cleaning.

One call is enough to establish three things: where your bath stands today, which step comes first, and how long it takes.
