INGOT MOULD FOR CONTINUOUS CASTING WITH A LUBRICANT CHANNEL OPENING TO THE RUNNING SURFACE

Abstract

An ingot mould for continuous casting, with a lubricant channel (2) opening to the running surface (1), has a distribution portion (3) adjoining the running surface (1). In an ingot mould of the aforementioned type a uniform lubrication of the running surface of the ingot mould is possible using as few wear-susceptible components as possible, where the flow resistance within the distribution portion (3) increases in the direction of the running surface (1) and is constant in a discharge region (4) of the distribution portion (3) adjoining the running surface parallel to the running surface (1).

Description

BRIEF DESCRIPTION OF THE INVENTION

[0013] In the drawing, the subject matter of the invention is shown by way of example. It shows

[0014] FIG. 1A sectional plan view of an ingot mould component of an ingot mould comprising two ingot mould components, and

[0015] FIG. 2 a sectional view along line II-II of FIG. 1 on an enlarged scale.

WAYS OF CARRYING OUT THE INVENTION

[0016] An ingot mould according to the invention for continuous casting comprises a running surface 1, and a lubricant channel 2 opening into the running surface 1 and having a distribution section 3 adjoining the running surface 1. The distribution section 3 comprises a discharge region 4 in which the flow resistance is constant parallel to the running surface 1. Within the distribution section 3, the flow resistance increases in order to induce a uniform distribution of the lubricant in the discharge region 4. This can be implemented, for example, by the discharge region 4 having a smaller cross-section and a different surface roughness than the region 5 of the distribution section 3 upstream of the discharge region 4. As a result of these measures, the distribution section 3 can extend circumferentially around the entire cross-section of a running surface 1 of an ingot mould.

[0017] Particularly favourable manufacturing and maintenance conditions result, as illustrated in FIG. 3, if the lubricant channel 2 is not made in one piece, but if two mould components 6, 7 bound the discharge region 4 in the axial longitudinal direction of the ingot mould. In the present embodiment, the two mould components 6, 7 abut each other in the area of the discharge region 4. Due to the rough surface of the discharge region 4 and the resulting fluid connection with high flow resistance to the running surface 1, the pressurised lubricant can pass from the section 5 upstream of the discharge region 4 to the running surface 1 despite the mould components 6, 7 being in contact with each other. Moreover, the cross-section of the lubricant channel 2 is thus reduced in the area of the distribution section 3, preferably abruptly in the transition area between the section 5 upstream of the discharge region 4 and the discharge region 4. If, in addition, one of the two mould components 6 comprises the running surface 1, the second mould component 7 can be constructed relatively compactly and can be replaced if necessary. In order to avoid loss of lubricant and to connect the at least two mould components 6, 7 in a pressure-tight manner, the ingot mould may comprise a seal 8. This seal 8 delimits the distribution section 3 of the lubricant channel 2 on the side opposite the distribution section 3. For lubricant supply, a lubricant supply opening 9 may be provided, which is fed via a supply line 10.
