Description

It has been thoroughly documented in previous Bridgeport Brass Company reports that a problem exists in the production of HAPO I and E ``O`` size slugs via the extrusion route due to an excessive number of rejects for I.D. seams. As a result of a previous short-run experiments, it was suggested that smaller I.D. billets be employed, thus reducing the reduction ratio on the I.D. It was thought that this factor may contribute to the seam formation in the extreme flow demanded of the metal. It was also thought that the long billets, half of an ingot, could contribute to … continued below

Description

It has been thoroughly documented in previous Bridgeport Brass Company reports that a problem exists in the production of HAPO I and E ``O`` size slugs via the extrusion route due to an excessive number of rejects for I.D. seams. As a result of a previous short-run experiments, it was suggested that smaller I.D. billets be employed, thus reducing the reduction ratio on the I.D. It was thought that this factor may contribute to the seam formation in the extreme flow demanded of the metal. It was also thought that the long billets, half of an ingot, could contribute to this defect. Therefore in this extrusion, some short billets, one-third of an ingot, were employed. Other methods or techniques for reducing the incidence of this I.D. defect will be studied later. It was intended to limit the present experiment to a study of the potential reduction involved in the above; namely, billet length and billet I.D., in an extrusion experiment with sufficiently large quantity of billets to give a fairly large number of slugs. By proper design, other contributors to the defect were held constant or randomized. This experiment proved definitely that a reduction in I.D. rejects due to seams and mechanical causes could be effected by a reduction in billet I.D. A conclusive result showed the 1 5/8 I.D. billet to produce the least extruded I.D. rejects. It was also found that extruded I.D.`s of less than .340 inch would improve the I.D. surface quality; that is, the incidence of the I.D. seam rejects. In this production run, a new method of packaging the I and E extruded rods resulted in receipt of rods at MCW with superior straightness. Therefore, the method of packaging for shipment in steel pans will be discontinued in the future.
