Abstract
The utility model provides a sintering furnace for powder metallurgy products, which comprises a feeding area, a preheating area, a sintering area and a cooling area, wherein an elongated metal hood is arranged at the front end of the feeding area and above the mesh belt of the sintering furnace. The cross section of the metal hood is in reserve C shape, and a heat insulation layer is arranged on the internal wall. The sintering furnace for powder metallurgy products has simple structure and reliability, utilizes the gas discharged from the furnace door for preheating the blanks which are to be fed into the sintering furnace and low-temperature derosination, improves the product quality, and realizes energy saving and discharge reduction.
Description
Technical field
The utility model relates to the net belt type sintering furnace of a kind of agglomerating plant, particularly sintered metal product sintering in a kind of sintered metal product production.
Background technology
The sintered metal product sintering is that the sintered metal product blank through press forming is put into the sintering oven curing that temperature is lower than the key component fusing point.At present, generally adopt net belt type ammonia atmosphere protection sintering furnace that sintered metal product is carried out sintering or degreasing, sintering in the industry.This sintering furnace mainly is made up of feed zone, preheating zone, sintering zone, cooling zone, ammonia tank, liquefied ammonia dore furnace and support.The exhaust structure of this type of sintering furnace is that the mist that forms from sintering zone and preheating zone is discharged through the exhaust pipe mouth burning back that feed zone is delivered to upwards.Blank from feed zone to the sintering zone time shorter, temperature rise is fast, causes the degreasing temperature rise too fast, makes that product is inner to produce huge gully, produces waste product.Owing to be the net belt type sintering furnace, can be that fire door is discharged a part of mist and taken away heat simultaneously, cause energy waste from charging aperture.
The utility model content
The purpose of the utility model is to provide a kind of sintered metal product sintering furnace, avoids the product temperature rise too fast, and the degreasing temperature rise that causes is too fast, improves product quality and production efficiency.
The technical scheme of the utility model is: a kind of sintered metal product sintering furnace, comprise feed zone, preheating zone, sintering zone, cooling zone, and wherein at the front end of said feed zone, the top of sintering furnace guipure is provided with the strip metal cap.
The cross section of said metal cap is the C shape of back-off.
The inwall of said metal cap is provided with insulating.
The utility model is simple in structure, and is easy for installation.Only set up a strip metal cap at the feed zone front end of existing sintering furnace; The gas that utilizes fire door to discharge carries out preheating in advance to the blank that will get into sintering furnace, product is carried out low-temperature defatted, improves the quality of products; Energy-saving and emission-reduction simultaneously realize efficient, automation steady production.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the cross-sectional structure sketch map of the utility model metal cap 3;
Among the figure: 1-feed zone, 2-guipure, 3-metal cap, 4-insulating.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Like Fig. 1 and Fig. 2, a kind of sintered metal product sintering furnace that the utility model provides comprises feed zone 1, preheating zone, sintering zone, cooling zone, and wherein at the front end of said feed zone 1, the top of sintering furnace guipure 2 is provided with strip metal cap 3.The cross section of said metal cap 3 is the C shape of back-off.
Preferably, the inwall of said metal cap 3 is provided with insulating 4.In the sintering course of work, be that fire door is discharged a part of mist and just can be drained through strip metal cap 3 from charging aperture.This moment, metal cap 3 played flowing of speed-raising hydrogen on the net belt type sintering furnace.Temperature maintenance can be carried out low-temperature defatted to product between 400 to 600 degree in the metal cap 3 of band insulating 4.
The utility model is simple in structure, reliable; Feed zone front end at existing sintering furnace is set up a strip metal cap; The gas that utilizes fire door to discharge carries out preheating and low-temperature defatted in advance to the blank that will get into sintering furnace, improves the quality of products energy-saving and emission-reduction simultaneously.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
Claims (3)
