Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the following in conjunction with the attached figure 1 , 2 And embodiment, the present invention is described in further detail.

[0023] Such as figure 1 Shown, the flow design method of a kind of cast roll of the present invention comprises the steps:

[0024] S1: Establish the geometric models of casting film, casting roll and cooling medium respectively.

[0025] Wherein, the cooling medium refers to a fluid medium, and one of conventional cooling mediums such as water, liquid ammonia, and air can be selected. The cooling medium and the casting film are respectively arranged on both sides of the casting roll, and the cooling medium flows in the casting roll to realize heat transfer; the casting film realizes the heat transfer with the cooling medium through the casting roll. The casting film is a film formed by casting extrusion; for example, it may be a polyethylen...

Abstract

The invention discloses a flow design method of a casting roller. The method comprises the following steps of firstly, respectively establishing geometric models of a casting film, the casting rollerand a cooling medium; secondly, discretizing a calculation region of the geometric models, importing the discretized calculation region into numerical simulation software, setting boundary conditions/physical property parameters, and performing numerical iterative calculation to obtain three-dimensional temperature field distribution characteristics of the casting roller, the casting film, the cooling medium; then, extracting axial temperature rise information of the casting film, and drawing an axial temperature rise curve of the film; and finally obtaining a relation curve of 'axial temperature rise slope - cooling medium flow velocity ' of the film, and conducting calculation according to a flow calculation formula to obtain flow Q meeting design requirements. According to the flow design method of the casting roller, the flow design of the casting roller can be quickly realized, and flow parameters meeting the design requirements are obtained. Specifically, the corresponding relation between the axial temperature rise slope and the flow velocity of the casting roller is obtained in a modeling simulation mode, the relation is substituted into a flow calculation formula, the flowrequired by the casting roller is obtained, and the method is rapid and accurate.

Description

technical field [0001] The invention belongs to the technical field of extrusion cast molding, and in particular relates to a flow design method of a cast roll. Background technique [0002] Extrusion casting is the main method of film production. The raw material resin is hot-melted and extruded from the die of the extruder. The molten resin is cast on the casting roll with a smooth surface through the machine head, and is cooled rapidly to form a film. It has equipment technology Simple, continuous production, small product defects, high production efficiency and other advantages. [0003] The cooling and forming process of the cast film mainly occurs on the casting roll. The casting roll is a steel roll with a large diameter. The inner sleeve is hollow and has a spiral deflector welded on the inner sleeve. , The space between the deflector fins forms a cooling medium flow channel. The cooling medium exchanges heat by flowing in the flow channel, and the appropriate flow...
