RVGQ-7710 Vacuum Gas Quenching Furnace with Top-and-Bottom Opposing Gas Flow Structure

2026-10-20 09:06

To achieve optimal quenching results, many customers are opting for vacuum gas-quenching furnaces featuring a top-and-bottom alternating gas-flow design, replacing conventional duct-based models. In these furnaces, the cooling medium alternates between top-in/bottom-out and bottom-in/top-out flows, ensuring rapid and uniform cooling. The heating chamber features a specialized design with enhanced sealing capabilities, allowing the unit to also serve as a high-quality tempering furnace.

SIMUWU RVGQ-7710 vacuum gas quenching furnace with top-and-bottom opposing gas flow structure for uniform cooling.
