Definitions
- This invention relates to. metal ingots and more par-' ticularly to a new and improved construction for ingots to enable stacking and to enable separation into separate segments.
- ingots have been cast with horizontally disposed notches extending to the base to enable bending about their horizontal axes for separation of the ingot into segments.
- This present practice has a number of disadvantages in that the stacks formed of the ingots are subject to shock when the stacks are laid down during the handling operations. Since the notch is formed by a triangular prism extending upwardly from the bottom of the ingot mold, the portion of the ingot which remains unaffected by the notch is much thicker and breaks with increasing dilficulty when ingots of increasing thickness are cast in the same ingot mold.
- the ingot mold formed of separated sections subdivides the mold into compartments so that one compartment receives metal only when the preceding compartment is filled to at least the height of the notch. This results in unsatisfactory equilibrium of the ingot by reason of the differences in the time of solidification to produce ingots in which the surfaces are undesirably at different levels. In practice, it is desirable that all parts of the ingot be cast simultaneously and to achieve this with present constructions markedly complicates the casting installation.
- FIG. 1 is a perspective elevational View of an ingot embodying the prior art
- FIG. 2 is a top plan view of the ingot shown in FIG. 1;
- FIG. 3 is a side elevational view of an ingot embodying the features of this invention.
- FIG. 4 is a top plan view of the ingot shown in FIG. 3;
- FIG. 5 is a sectional view taken along the line 55 of FIG. 4.
- the ingot is formed with at least one notch extending throughout the height of the ingot and formed in such a way that the corresponding cut is vertical.
- the described notches are formed in pairs with the two notches in each pair being disposed in substantially the same vertical plane perpendicular to the largest dimension of the ingot.
- FIGS. 1 and 2 there is illustrated an ingot 1 of the prior art having a base 3 at the bottom on which the ingot rests and a base 4 of smaller dimension'at the top with the opposite side faces 5 and 6 and end faces'7 and 8 generally tapered from bottom to top to define a prismatic section.
- a vertical notch 11 extends crosswise of the ingot intermediate its ends from the top base -4 downwardly for a distance short of the bottom base to divide the ingot into two sections for easy separation.
- the illustrated structure has a number of serious disadvantages.
- the ingots are generally assembled in stacked relation for distribution and delivery. Because of the inevitable differences in the height of the different ingots making up each of the layers, the ingots are subject to vertical shocks to produce strains by fiexure about a horizontal axis perpendicular to their length. It is me cisely along this axis thatthe presence of the notch increases the fragility of the ingot and often results in fracture.
- the ingot is cast in a mold which corresponds to the shape of the ingot but which is cast in an inverted form with the large base uppermost.
- the ingot mold thus comprises a prismatic section corresponding to the notch 11.
- This prismatic section separates the lower part of the ingot mold into two compartments which, during the casting of the ingot, are successively filled.
- the section which does not directly receive the poured metal remains empty until the metal overflows the first compartment. Since the ingot mold is generally unheated, the metal Which remains in the first compartment, while the second compartment is being filled, will become solidified. This results in a thermal imbalance which is demonstrated by the lack of balance in the shape of the completed ingot wherein the large base is no longer flat. It will be obvious that the pile of ingots will produce a relatively unstable stack.
- the ingot represented in FIG. 3 and embodying the features of this invention has the same general configuration as that of FIG. 1 in that it is formed with a large base 3 at the bottom, a smaller base 4 at the top, and side and end faces 5, 6, 7 and 8 which define an ingot of prismatic shape.
- the notch which is intended to facilitate separation of the ingot into sections is formed in at least one of the large lateral faces 5 and/or 6.
- This vertical arrangedment or notch or notches in the 0 side portions of the ingot has the effect that the force to be applied for breaking the ingot is exerted in a direction perpendicular to that of the vertical forces originating from the shocks during the normal handling of the stacks of ingots.
- the ingot maintains all of its resistance to such shocks while still remaining capable of breakage into separate segments with very little force.
- the ingot mold is no longer subdivided by a vertical darn into separate compartments such that the filling thereof remains uniform throughout the crosssection of the ingot during metal pouring since all portions of the ingot are interconnected one to the other at all levels.
- the height of the notch is equal to the total height of the ingot notwithstanding the height of the metal poured into the same ingot mold. As a result, the force to be exerted for breaking the ingot varies only slightly with the thickness or height.
- the slight variations in the breaking force to thickness can be corrected by the material retained, either between the single notch and the large unaffected opposite face of the ingot, or between the two notches constituting a pair formed in the same vertical plane perpendicular to the largest dimension of the ingot, starting with a section which varies with the distance of said section from the large face; this section may more particularly be increasing or decreasing, or decreasing and then increasing, or finally increasing and then decreasing.
- the invention described is particularly suitable with ingots formed of aluminum or alloys of aluminum or of magnesium or alloys of magnesium and it is also applicable to other cast materials.
- An ingot of prismatic shape having fiat bottom and top walls and vertically disposed side and end walls with the side walls having a length greater than the end walls and a notch extending inwardly from at least one of the side walls throughout the height of the ingot from the bottom wall to the top wall and for a distance to include the major width of the ingot whereby only a minor section of the ingot extending continuously from the top wall to the bottom wall remains to join the segments of the ingot on opposite sides of the notched portion.
