Abstract

The utility model relates to the technical field of machining equipment, and particularly relates to a heating furnace for eliminating zinc spots of a strip. The heating furnace comprises a furnace hearth, wherein a strip heating area is arranged in the furnace hearth; a guide plate is arranged above the strip heating area. The heating furnace for eliminating the zinc spots of the strip has the following beneficial effects that during heating, zinc steam forms a zinc steam cluster when coming in contact with the guide plate, and the zinc steam cluster flows downwards along the guide plate without dropping on the strip, so that the zinc spots are eliminated, quality of products is improved, and service lives of the products are prolonged.

Description

A kind of process furnace of eliminating band zinc spot

Technical field

The utility model relates to band technical field of processing equipment, is specifically related to a kind of process furnace of eliminating band zinc spot.

Background technology

Metal current composite strip processing industry; containing platina (as German silver, brass series) thermal treatment time; when thermal treatment temp is during higher than 500 ℃; zinc in copper alloy can evaporate gradually, and along with the rising of temperature and the increase of time, the zinc evaporating forms steam; in enclosed space, add the effect of mobility shielding gas; after conglomeration, be dropped in strip surface, and produce zinc spot, thereby affect the outward appearance of product and use electric life.

Utility model content

The purpose of this utility model is for the defect of prior art and deficiency, and a kind of process furnace of eliminating band zinc spot is provided.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of process furnace of eliminating band zinc spot described in the utility model, comprises burner hearth, is provided with band heating zone in burner hearth, and the top of described band heating zone is provided with flow deflector.

As preferably, described flow deflector is herring-bone, and the top of flow deflector is fixed on burner hearth upper end wall.

As preferably, described flow deflector and burner hearth inner side-wall leave gap.

As preferably, the gap of flow deflector and burner hearth inner side-wall is less than the gap between band heating zone and burner hearth inner side-wall.

Adopt after said structure, the utility model beneficial effect is: when heating, zinc fume runs into flow deflector and forms zinc fume group, dirty and can not drop onto above band along flow deflector, eliminates zinc spot, quality and the work-ing life of having improved product.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical solution of the utility model, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is one-piece construction schematic diagram of the present utility model.

Description of reference numerals:

1, burner hearth, 2, band heating zone, 3, flow deflector, 4, burner hearth inner side-wall, 5 zinc fume groups.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a kind of process furnace of eliminating band zinc spot described in the utility model, comprise burner hearth 1, in burner hearth 1, be provided with band heating zone 2, the top of described band heating zone 2 is provided with flow deflector 3, and described flow deflector 3 is herring-bone, and the top of flow deflector 3 is fixed on burner hearth upper end wall, flow deflector 3 leaves gap with burner hearth inner side-wall 4, and this gap is less than the gap between band heating zone 2 and burner hearth inner side-wall 3; When heating, zinc fume runs into flow deflector and forms zinc fume group 5, dirty and can not drop onto above band along flow deflector 3, eliminates zinc spot, quality and the work-ing life of having improved product.

The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.

Claims

1. eliminate a process furnace for band zinc spot, comprise burner hearth (1), in burner hearth (1), be provided with band heating zone (2), it is characterized in that: the top of described band heating zone (2) is provided with flow deflector (3); Described flow deflector (3) is herring-bone, and the top of flow deflector (3) is fixed on burner hearth (1) upper end wall; Described flow deflector (3) leaves gap with burner hearth inner side-wall (4); The gap of flow deflector (3) and burner hearth inner side-wall (4) is less than the gap between band heating zone (2) and burner hearth inner side-wall (4).
