Abstract
The utility model relates to a spheroidizing annealing furnace. The spheroidizing annealing furnace comprises a furnace body, a furnace cover and a furnace bottom, as well as a circulating fan, an inner barrel and a convection barrel which are arranged in the furnace body, and the spheroidizing annealing furnace is characterized in that an inner barrel sealing head, a flow guide plate and a charging disc are sequentially placed on the furnace bottom, wherein the charging disc is arranged in the convection barrel. The flow guide plate consists of an upper support plate and a lower support plate so as to form forming convection eight trigrams and enable heat in the furnace and protective atmosphere to form strong convective circulation; and the outer bottom of the inner barrel is in the shape of a spherical surface, and heat insulation material is filled at the lower part of the inner barrel. The flow guide plate is arranged in the inner barrel of the spheroidizing annealing furnace, so that the spheroidizing annealing furnace is not only low in cost, but also easy to detach and mount, and workload is further reduced, furthermore, the flow guide plate is separated from the furnace bottom, the spheroidizing annealing furnace can ensure that the furnace bottom is not easy to damage; and in addition, as the flow guide plate is better in permeability, gas in the furnace is always in a high-speed and ordered state.
Description
Technical field
The utility model belongs to kiln, roaster group in International Patent Classification (IPC), specially refer to industrial furnace parts group.
Background technology
In the Spheroidizing Annealing furnace apparatus of wire rods such as soft steel, medium carbon steel, low alloy steel, dish circle, comparatively sophisticated have bell-type furnace and a pit furnace.Former structure is complicated, troublesome poeration; The convective of latter's furnace atmosphere is poor.To the deficiency of prior art, the Chinese patent that No. 200620139918.5, application number, emphasis have been considered coincideing of interior bucket and furnace bottom, have increased contact area, have increased the steadiness of placement.But the difficult problem in still existing during the fragile and upkeep cost in bucket bottom surface.
Summary of the invention
The purpose of the utility model is to provide a kind of spheroidizing annealing furnace.
The difficult problem that the utility model will solve when being interior bucket bottom surface rapid wear and the upkeep cost of existing spheroidizing annealing furnace is to make things convenient for installing and replacing.
The technical scheme of the utility model is: it comprises draws together body of heater, bell and furnace bottom, is located at the intravital air-circulating fan of stove, interior bucket and convection current bucket, puts successively on the furnace bottom to put interior bucket end socket, flow deflector and loading tray, and loading tray is located in the convection current bucket.
The flow deflector of the utility model is easy to make and welding, and the utility model can guarantee that through setting up flow deflector at furnace bottom furnace bottom is not fragile.
The utility model has been owing to adopted Eight Diagrams flow deflector, so permeability is good, can make that furnace gas is at a high speed all the time, orderly state.And because the structure of Eight Diagrams flow deflector and convection current bucket; Air-flow can be descended along gap between interior bucket and the convection current bucket; In the convection current bucket, upwards form convection current then; Make furnace heat and protective atmosphere form the strong convection circulation, significantly improved the rate of cooling of temperature uniformity, the uniformity of the physicals of the wire rod of guaranteeing to anneal.Wire microstructure after the annealing is even, stable mechanical property, has eliminated internal stress, and plasticity-is strong, lets the line of taking out of next processing procedure be more prone to, and reduces the infringement to board and mould, and promotes the wire rod quality and safeguard the security of producing.
