Abstract
The invention discloses a casting-rolling nozzle which comprises a lug arranged at the edge part of a material outlet at front end of the nozzle, wherein a chamfer is formed at the inner side of the lug and has a linear front section and an arc-shaped rear section, the linear front section is tangent to the arc-shaped rear section at the joint, the liner front section of the chamfer is vertical to the front edge of the nozzle, and the root part of the arc-shaped rear section of the chamfer is flush with the front edge of the nozzle. The casting-rolling nozzle has the advantages that the lug clings to the front edge of the nozzle through adjusting the lug structure at the edge part of the casting-rolling nozzle; and when the casting-rolling nozzle is in use, the gap between the nozzle and a roller is more reasonable, and the casting-rolling edge crack depth is reduced and even eliminated, so that the cutting quantity in follow-up processing is reduced, the yield of final products is improved, and the utilization rate of aluminum coiled materials is increased.
Description
Technical field
The present invention relates to a kind of aluminium alloy process equipment, particularly a kind of casting lip that is used for the aluminium alloy casting and rolling installation.
Background technology
Casting lip is mounted in the preceding parts to the channeling conduct of aluminium alloy material of roll of aluminium alloy casting and rolling installation; Liquid aluminium alloy material gets into lip from the charging aperture of its rear end; See and get into roll off from the discharging opening of its front end again, through roll cooling and be rolled into cast-rolling stock.The ears or side handles of a utensil of lip front end discharging opening limit portion have directly determined the casting coil breaks limit degree of depth; Casting coil breaks limit can be excised in the following process process, and the raw edges degree of depth is more little, and the amount of following process excision is more little; Final yield rate is high more, thereby the structure of casting lip has significant effects to casting production.
Summary of the invention
Goal of the invention:, the purpose of this invention is to provide a kind of casting lip that can reduce the casting raw edges degree of depth, reduce loss to the problems referred to above.
Technical scheme: a kind of casting lip, comprise the ears or side handles of a utensil of lip front end discharging opening limit portion, chamfering is arranged in said ears or side handles of a utensil inboard.
Said chamfering leading portion is a linear pattern, and said chamfering back segment is an arc line type, and said linear pattern and said arc line type junction are tangent.
Said chamfering is 20 °.
The linear pattern of said chamfering leading portion is vertical with the lip forward position, and the arc line type root of said chamfering back segment flushes with the lip forward position.
Beneficial effect: compared with prior art; Advantage of the present invention is through the ears or side handles of a utensil structure of adjustment casting lip limit portion, makes the ears or side handles of a utensil be close to the lip forward position, and during use and roll seam is reasonable further; Reduce even eliminated the casting raw edges degree of depth; Make the amount of following process excision reduce, improved the yield rate of final products, increased the utilization rate of aluminium coiled material.

Fig. 2 is the zoomed-in view of the ears or side handles of a utensil;
Fig. 3 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Shown in accompanying drawing 1-3, a kind of casting lip comprises the ears or side handles of a utensil 1 of lip front end discharging opening limit portion, and chamfering 2 is arranged in the ears or side handles of a utensil 1 inboard.This chamfering 2 is 20 °, the arc of indent, and the leading portion in chamfering 2 is a linear pattern 3 especially, and this linear pattern is vertical with lip forward position 5, and back segment is an arc line type 4, and these arc line type 4 roots flush with lip forward position 5, and linear pattern 3 is tangent with arc line type 4 junctions.
Chamfering 2 is from being provided with apart from the ears or side handles of a utensil 1 front end 20～40mm, and wherein the length of linear pattern 3 is 15～30mm, and the length of arc line type 4 is 5～10mm.Chamfering is smooth, no burr.
