CN201423387Y - Casting mouth structure of cast-rolling aluminum coil - Google Patents

Abstract

The utility model provides a casting mouth structure of a cast-rolling aluminum coil, which is characterized in that an oblique angle is formed on the front side of a molding rolling edge of a castingmouth of the cast-rolling aluminum coil; graphite paper is mounted between the casting mouth and the molding rolling edge; and the oblique angle is 10 to 20 degrees, of which the starting point is 0to 10 millimeters away from the front edge of the casting mouth. The casting mouth structure of the cast-rolling aluminum coil provided by the utility model ensures that the starting point and the angle of the oblique angle on the front side of the molding rolling edge are the same to the aluminum liquid solidification starting point and the rolling broadsiding angle, thereby eliminating the limitation of rolling broadsiding. The graphite paper insulates aluminum liquid from contacting with the front of the starting point of the oblique angle of the molding rolling edge and plays the role of lubrication, thereby preventing the aluminum liquid from bonding in the front of the oblique angle of the molding rolling edge.

Description

A kind of lip structure of aluminium casting volume

Technical field

The utility model relates to the aluminium processing technique field, specifically a kind of lip structure of aluminium casting volume.

Background technology

The blank of Aluminum Plate and Strip production at present has hot rolling blank and cast-rolling stock two classes, the hot rolling blank production process is melting-online processing-casting-ingot casting sawing-mill face-heating-hot rolling-hot rolling blank, and the cast-rolling stock production process is melting-online processing-casting-cast-rolling stock.Hot rolling method process route is long, and floor space is big, and investment is big, and the construction period is long, and yield rate is low, the production cost height, so casting and roll process is developed rapidly with its diametrically opposite characteristic and advantage since nineteen seventies.Casting and roll process is exactly with lip the inside that aluminium liquid continuously is transported to a pair of rotation to be connected with between the casting roller of cooling water, makes aluminium liquid solidification and crystallization and obtain rolling and produce aluminum slab continuously.Because aluminium liquid is subjected to rolling spreading in solidification and crystallization process by using, the casting volume can produce the technology raw edges, and the technology raw edges is generally at 5～10 millimeters, and broken belt can be deepened even cause to casting volume technology raw edges in cold rolling production, increases cold rolling side cut amount, influences cold rolling yield rate.

Summary of the invention

The purpose of this utility model is to produce reason at casting volume technology raw edges, i.e. lip structure problem provides a kind of lip structure of aluminium casting volume.

The technical solution of the utility model is: the lip moulding ears or side handles of a utensil front of aluminium casting volume is the oblique angle, and the oblique angle is 10～20 ° (adjusting the angle and the size of the ears or side handles of a utensil according to different aluminum alloys), and between the lip and the moulding ears or side handles of a utensil graphite paper is housed.

The lip structure of aluminium casting of the present utility model volume makes moulding ears or side handles of a utensil front oblique angle starting point and angle solidifies starting point with aluminium liquid and the rolling angle of spreading is consistent, eliminates rollingly to spread limitedly, prevents that casting from rolling up the generation of technology raw edges.The effect of graphite paper is to isolate aluminium liquid and moulding ears or side handles of a utensil oblique angle starting point contacting before, and lubricate prevents that aluminium liquid is bonded in before the moulding ears or side handles of a utensil oblique angle starting point.

Description of drawings

Fig. 1 is a lip structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, the lip structure of aluminium casting volume of the present utility model is: the moulding ears or side handles of a utensil 1 front of the lip 2 of aluminium casting volume is the oblique angle, the oblique angle is 10～20 °, 0～10 millimeter of oblique angle starting point in the lip forward position, can adjust the angle and the size of the ears or side handles of a utensil according to different aluminum alloys, make moulding ears or side handles of a utensil front oblique angle starting point and angle and aluminium liquid solidify starting point and the rolling angle of spreading is consistent.And the graphite paper 3 of two 1 millimeters thick is housed between the lip and the moulding ears or side handles of a utensil, the graphite paper size is identical with moulding ears or side handles of a utensil sectional dimension.

Claims (2)

1, a kind of lip structure of aluminium casting volume is characterized in that the lip moulding ears or side handles of a utensil front of aluminium casting volume is the oblique angle, between the lip and the moulding ears or side handles of a utensil graphite paper is housed.

2, the lip structure of aluminium casting volume according to claim 1 is characterized in that described oblique angle is 10～20 °, 0～10 millimeter in the lip forward position of oblique angle starting point.
