Brilliant isothermal normalizing production system

Abstract

The invention relates to a bright isothermal normalizing production system which comprises a feeding table, a normalizing heating furnace, a sealed fast cooling chamber, an isothermal furnace, a water cooling chamber and a discharge table, wherein, the feeding table, the normalizing heating furnace, the sealed fast cooling chamber, the isothermal furnace, the water cooling chamber and the discharge table are sequentially connected to form a run-through inner cavity inside; a front vacuum chamber is arranged between the feeding table and the normalizing heating furnace, a transition chamber is arranged between the normalizing heating furnace and the sealed fast cooling chamber, a rear transition chamber is arranged between the sealed fast cooling chamber and the isothermal furnace, and a rear vacuum chamber is arranged between the water cooling chamber and the discharge table; sealing doors are respectively arranged at openings at two ends of the normalizing heating furnace, the sealed fast cooling chamber, the isothermal furnace, the front vacuum chamber and the rear vacuum chamber; and a water cooling chamber door is arranged at the end face of the opening of the water cooling chamber close to the rear vacuum chamber. The production system has the beneficial effect of no oxidization of the heat treated products, small hardness scattering difference, saving energy and materials, solving the problems of unstable product quality and severe burning loss and oxidization of steel products. The bright isothermal normalizing realizes the ideal effect of high quality, energy and materials saving, and environmental protection.

Description

technical field [0001] The invention mainly relates to the field of heat treatment equipment for alloy steel, and is mainly a bright isothermal normalizing production system. Background technique [0002] In recent years, with advanced isothermal normalizing technology instead of general normalizing, alloy steel can obtain a more ideal equiaxed grain structure, significantly improve mechanical properties and reduce final heat treatment deformation. This advanced technology is widely used in the manufacturing industries of automobiles, motorcycles, gears and precision parts. [0003] The isothermal normalizing production line is the key equipment for implementing this technology. In the prior art, the isothermal normalizing production line appears as a pusher furnace, the heating and cooling equipment has no protective atmosphere, and the oxidation and decarburization are serious. As we all know, the push rod furnace is used for heating, the push rod mechanism, the material...

AI Technical Summary

Problems solved by technology

As we all know, using a push rod furnace for heating, the push rod mechanism, material tray, and material basket are heavy, and there are disadvantages such as long heating time and uneven heating, large fluctuations in product quality, high energy consumption, and high steel burning rate
