Alarge Die steel Quenching hardness high pressure vacuum gas quenching furnace
1).Horizontal, single chamber, horizontal loading type
2).Excellent temperature uniformity realized by optimized furnace hearth.
3).For different cooling speed requirements, it can use single heat exchanger furnace hearth cooling or dual and multi-stage heat exchanger furnace hearth cooling
4).Inverter starting of air cooling motor
5).Classification of isothermal quenching(optional)
Gas quenching furnace used in machinery manufacturing, aerospace and other industries. It is used for gas quenching of materials like tool steel ,die steel, high speed steel super high strength steel and also used for stainless steel, titanium and titanium alloy solution treatment. The gas quenching furnace has horizontal single-chamber structure, composed by furnace body, furnace cover, heating chamber and forced circulation cooling device etc.
