Abstract
The utility model discloses a well-type protective atmosphere annealing oven which comprises an inner barrel and an outer barrel. A clearance is provided between the inner barrel and the side part of the outer barrel. The upper end of the outer barrel is installed with an oven cover. The outer layer of the outer barrel is packed with a heat insulation layer. The bottom of the inner barrel is installed with a material loading disc. The inner side surface of the oven cover has an inward concave arc shape. The oven cover is installed with a convection fan. The blades of the convection fan are positioned below the oven cover and are in the space comprising the inner barrel. As the oven cover of the well-type protective atmosphere annealing oven which is provided by the utility model is installed with the convection fan, and furthermore the inner side surface of the oven cover has an inward concave arc shape, the convection fan can supply air the inner barrel so that the air current in the annealing oven forms the convection. Additionally the inner side surface of oven cover which has an arc shaped can guide the air transmitted out by the convection fan to the periphery, the convection effect can be increased thereby equalizing the temperature of each component in the annealing oven thereby increasing the production efficiency and increasing the spheroidizing grade.
Description
Technical field
The utility model well formula special atmosphere furnace.
Background technology
Often the temperature of the interior each several part of body of heater is very inhomogeneous down in working order for the annealing furnace of Xiao Shouing in the market, and tracing it to its cause mostly is owing to adopt effective means to carry out the convection current processing in the structure of annealing furnace.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of gas that can make the body of heater each several part and carries out well formula special atmosphere furnace than strong convection.
For this reason; bucket and outer bucket in the well formula special atmosphere furnace that the utility model provides comprises; leave between interior bucket and the outer bucket sidepiece and have the space; the upper end of outer bucket is provided with bell; outer bucket skin is enclosed with thermal insulation layer, and the bottom of interior bucket is provided with the material containing dish, and the bell medial surface is the arc shape of indent; convection flow fan is installed on the bell, and the flabellum of convection flow fan is in the bell below and is in the affiliated space of interior bucket.
Owing on the bell of the well formula special atmosphere furnace that the utility model provides convection flow fan is installed; and the bell medial surface is the arc shape of indent; convection flow fan is inwardly blown in the bucket; make the air-flow in the annealing furnace form convection current; guide around the wind direction that the planar bell medial surface of arc can be sent convection flow fan in addition, can strengthen convection effects, thereby make the temperature at each position in the annealing furnace comparatively balanced; thereby can enhance productivity, improve nodulizing grade.
