Luoyang Hongyuan Bearing Technology Co., Ltd.
Installation, two-stage filtration and furnace cleaning completed in four days; both customer re-checks passed.
Background
The quench furnace and salt bath had run for years. A thick deposit had built up inside the furnace, and the molten salt carried visible suspended solids. Both temperature uniformity and salt cleanliness had degraded, and the customer wanted them addressed without a long shutdown.
What we did
Furnace interior cleaning
Equipment arrived on 4 March and was installed by 16:52; piping and cabling were completed on 5 March with three operators on shift.
On 6 March the bath was filtered and re-filtered with a fresh screen to improve fine-particle capture.
From 7 to 8 March the furnace interior was cleaned while filtration of the salt bath continued.
What changed
- The customer sampled on 7 and 8 March; both checks passed.
- With the furnace cleaned, temperature uniformity recovered and suspended solids in the bath dropped noticeably.
- Equipment was demobilised after joint confirmation, closing the job in four days.
