High Pressured vacuum oil /gas quenching furnace:
Vacuum quenching refers to achieving a clean quenching of parts. Quenching and cooling of parts in a vacuum furnace, quenching medium is mainly gas (such as inert gas), water and vacuum quenching oil. High Pressured vacuum oil /gas quenching furnace has been widely used in a variety of carburizing steel, alloy tool steel, high-speed steel and stainless steel quenching, as well as a variety of aging alloys, hard alloys, and other materials. Solid solution treatment of magnetic alloys.
There are two types of quenching in vacuum: gas quenching and liquid quenching. Gas quenching means that the workpiece is heated in a vacuum and cooled in a cooling chamber with a high purity neutral gas (e.g. nitrogen). Suitable materials for gas quenching are high speed steels and high carbon and high chromium steels, which have a low critical cooling rate for martensite. Liquid quenching is a process where the workpiece is heated in a heating chamber, then moved to a cooling chamber where it is filled with high purity nitrogen and immediately fed into a quenching oil bath for rapid cooling. If high surface quality is required, the workpiece should still be tempered and precipitation hardened in a vacuum furnace after vacuum quenching and solid solution heat treatment.
Vacuum high pressure gas quenching furnace is a super advanced vacuum heat treatment equipment, its outstanding performance and unique design provide a wide range of Suitable for vacuum bright gas quenching, annealing and hardening of high speed steel, die steel, stainless steel, alloy steel, titanium alloy and other high precision parts made of alloy materials. Features such as sintering of magnetic materials and rapid cooling. The High Pressured vacuum oil /gas quenching furnace consists of a heated furnace hood and a mobile base. The square (or round) hood is topped with a crane, which lifts the baskets by chains and hooks into the furnace chamber. The hood is supported by a beam and has a pneumatically (or electrically) operated door at the bottom. The floor below the hood is moved and positioned on rails and contains the quench tank and the charge baskets. During production, the baskets on the bottom shelf are moved directly under the hood, the door is opened, the chains and hooks are lowered and the baskets are lifted into the furnace chamber, and the door is closed. Heating is carried out afterwards.
The quenching is carried out by moving the water tank on the bottom shelf directly under the hood, then opening the door, lowering the chain, and quenching the basket (workpiece). In water.
