Cooling protective gas is introduced into the inner cover of the furnace body and directly used for cooling workpieces, meanwhile, the outer wall of the inner cover is cooled with water through a water spray device outside the inner cover, and the workpieces are indirectly cooled, so that the workpieces are cooled quickly under double cooling actions, the cooling speed is improved, an aim of quick cooling is fulfilled, and the heat treatment efficiency is improved.
Description
Technical field
The utility model belongs to the shield type bright annealing oven technical field, relates in particular to a kind of cooling system of shield type bright annealing oven.
Background technology
Along with the high development of market economy, the demand of bands such as the copper strips of ferrous metal and non-ferrous metal clean annealing, steel band is constantly increased, and these bands to be in process of production, its thermal treatment process mainly relies on shield type bright annealing oven.Shield type bright annealing oven mainly is made up of outer cover, inner cover, table, vacuum system and electric control system, and during work, workpiece places the inner cover that is full of protective atmosphere; When workpiece need heat; Thermal source by being arranged on the outer cover heats inner cover in advance, gives product to be heated by inner cover heat transfer, radiation, convection current, and table is provided with the strong convection recirculation blower; Make the protection gas in the inner cover circulate strongly, the homogeneity of temperature and heat transfer, rate of heating in the enhancing stove; Workpiece after heating is accomplished need carry out the insulation of certain hour and the cooling after the insulation, during work-piece cools; Remove the outer cover when being used for heated parts; Change cooling cowl, rely on the waterworks that is provided with on the cooling cowl, to the inner cover cooling of spraying water; Protection gas in the indirect cooling inner cover, and then cooling workpiece.
This simple indirect cooling workpiece of water-cooling pattern that utilizes, the cooling of workpiece is comparatively slow, and effect is lower, has had a strong impact on the thermal effectiveness of extraordinary workpiece.
Summary of the invention
For addressing the above problem, the purpose of the utility model provides a kind of cooling system of shield type bright annealing oven, can cool off the workpiece after the heating fast, improves the thermal effectiveness of workpiece.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of cooling system of shield type bright annealing oven comprises body of heater, water cooler and blower fan, and body of heater mainly is made up of outer cover, inner cover and table; The inlet mouth of water cooler links to each other with the entrance end of blower fan through airduct; The exit end of blower fan is communicated with the inner chamber of body of heater inner cover through pipeline A, and described pipeline A is provided with arm, and arm is provided with valve A; The air outlet of water cooler is communicated with the inner chamber of inner cover through pipeline B, and pipeline B is provided with valve B.
The cooling system of described shield type bright annealing oven is connected with the cooling water circulation loop that is used for cooling gas on its water cooler.
The cooling system of described shield type bright annealing oven, the outer wall of its inner cover is provided with waterworks.
Owing to adopt technique scheme, the utlity model has following meliority:
The cooling system of this shield type bright annealing oven through in the body of heater inner cover, feeding refrigerative protection gas, directly cools to workpiece; Simultaneously, workpiece is cooled off in the cooling of spraying water of the outside internal cover outer wall of waterworks of inner cover indirectly; Workpiece is under two cooling effects, and speed of cooling is accelerated, and has improved speed of cooling; Reach quick cooling purpose, improve heat treated work efficiency.
