Embodiment Construction

[0034] A preferred embodiment of the invention is generally shown in Figure 1, wherein the casting station comprises a molten metal supply launder 10, a casting mold 11 and a removable metal transfer between the launder and the mould. paragraph 12. The continuous casting operation itself and the molds used for this purpose do not form an essential part of the invention and will therefore not be discussed in detail. Of course, it should be understood that the drawn and continuously cast bars will have solidified sufficiently before the point at which they are subjected to downstream processing that the physical configuration or surface quality characteristics of the cast metal bars are not adversely affected. Suitable casting molds are more fully described in copending application Ser. No. 10 / 735,076 entitled "Horizontal Continuous Casting of Metals," filed December 11, 2003, and assigned to the same assignee as the present invention, The disclosure of that patent application ...

Abstract

The invention relates to an apparatus for continuous casting of metal billets comprising a horizontal casting mould having and inlet end and an outlet end. It includes a feed trough for feeding molten metal to the mould inlet end and a horizontal conveyor for receiving a cast billet from the mould outlet end. A moveable cutting saw is operable to move synchronously with the conveyor for cutting a continuous billet into lengths while supported on the conveyor. The billet is resiliently supported and the saw mechanism is isolated so as to minimize transmission of low and high frequency vibrations from the cutting and conveying operations to the mould.

Description

technical field [0001] The present invention relates to horizontal casting equipment for the continuous casting of metal bar stock, such as aluminum bar stock. Background technique [0002] Metal bars are usually produced using vertical direct chill casting operations as well as horizontal casting methods. A typical horizontal mold is described in US Patent No. 3,630,266. [0003] Horizontal casting has the advantage of being able to produce bars continuously, but as a result special equipment is required to ensure continuous and smooth extraction of bars and cutting them to length without interrupting the continuous process. [0004] Canadian Patent No. 868,197 to Gordon and Scott describes a horizontal casting machine for casting aluminum bar stock. The horizontal casting machine includes clamping rollers for moving the cast bar and a flying saw for cutting the bar to lengths. [0005] In US Patent No. 4,212,451 to Klotzbücher et al., a horizontal casting machine is use...
