Quench Log & Process Notes

Trishana Bijoy Naruka

HVF-2000 run #47: chrome-moly billet, 1050°C soak, gas quench at 2.5 bar. Grain size ASTM 7.5. Crucible condition good.

Juhi Sai Bhatia

Refractory crucible set #12 inspected after 18 cycles. Minor thermal fatigue on lip, scheduled for replacement next week.

Vacuum leak detected on furnace door seal. Replaced O-ring, re-ran leak test. Acceptable rate: 0.02 mbar·L/s. Logged for maintenance.

What our partners say about our sintering systems

Real results from the foundry floor

Consistent grain refinement across 200+ production runs

Our QuenchPro module paired with the HVF-2000 furnace delivered repeatable cooling profiles for chrome-moly steel. The alumina-graphite crucibles held up through 40+ cycles without cracking.

Senior Metallurgist · Midwest Alloy Works

The vacuum induction furnace held temperature within ±5°C during the entire sintering cycle. We saw a measurable reduction in porosity after switching to your crucible set.

Rajesh K. Quality assurance lead
Process Engineer · Apex Steel Solutions

We needed a repeatable quench for our chrome-moly test batches. The control module let us program a three-stage profile — gas, oil, then air — and the data logging proved our process to the client.

After switching to your refractory crucibles, our melt loss dropped by 12%. The thermal shock resistance is exactly what we needed for our daily quench cycles.

Lab Director · Advanced Metallurgy Institute

The HVF-2000 furnace allowed us to run sintering experiments at 1850°C with precise ramp rates. The integrated quenching system gave us the fine-grained microstructure we were after.
