Embodiment Construction

[0014] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] like figure 1 and figure 2 As shown, in a specific embodiment, the vacuum furnace quenching oil cooling system for heat treatment provided by the present invention includes a quenching oil tank 1, a quenching oil stirring and lifting device 2 and other components.

[0016] Water-cooled walls 101 are laid on the left and right ends of the top wall of the quenching oil tank 1 , and water circulation pipes are installed in the water-cooled walls 101 , and the water-cooled walls 101 can exchange heat with the external environment.

[0017] In this embodiment, two sets of quenching oil stirring and lifting devices 2 are provided, which are respectively arranged at the positions of two water-cooled walls 101. Each group of quen...

Abstract

The invention provides a vacuum furnace quenching oil cooling system used for thermal treatment. The vacuum furnace quenching oil cooling system comprises a quenching oil tank. A water cooling wall and multiple sets of quenching oil stirring and lifting devices penetrating the water cooling wall are arranged on the top wall of the quenching oil tank. The quenching oil stirring and lifting devices extend into the quenching oil tank downwards and are used for lifting quenching oil in the quenching oil tank to the position of the water cooling wall so that the quenching oil can be cooled. Compared with the prior art, the vacuum furnace quenching oil cooling system has the following remarkable technical effects that it is ensured that the quenching oil in the quenching oil tank is uniformly cooled, the stirring speed of stirrers can be flexibly controlled, and therefore the cooling speed of the quenching oil is flexibly regulated.

Description

technical field [0001] The invention relates to a heat treatment device, in particular to a vacuum furnace quenching oil cooling system for heat treatment. Background technique [0002] Vacuum furnace is regarded as one of the equipments for upgrading equipment in the heat treatment industry. The important reason is that the product parts processed by vacuum furnace have bright surface, less oxidation, good performance and high precision. It is easy to realize energy saving, consumption reduction and reduction in the production and operation of vacuum furnace. It belongs to clean production equipment and meets the requirements of today's environmental protection. There are very few gas molecules in vacuum, and the free path of molecules becomes larger, so light rare metals, refractory metals, rare metals and other special alloy materials that cannot be obtained under normal pressure can be produced. [0003] In the prior art, the quenching oil cooling system of the vacuum f...
