Definitions

  • This invention comprises a discovery that the glass compositions hereinafter described maintain a lubricating viscosity in the temperature range from about 300 C. to about 550 C. and may be used as lubricants for drawing metals and alloys having low melting points, especially aluminum and its alloys, for which the temperature reached by the lubricant during working or drawing falls in this range.
  • the fritting temperature of the novel glasses described herein is between about 280 C. and 440 c.
  • the speed of drawing may be increased to the order of 15 to 50 m. per minute, in particular in the drawing of aluminum and its alloys.
  • the gross peripheral grains are not produced after subsequent thermal treatment.
  • the axial recess is eliminated.
  • An especial advantage is that .theseglasses can be removed from the surface to increase its chemical and weather resistance.
  • the P 0 B 0 and Alumina may or may not contain A1 0 but if it is present the total amount of P 0 B 0 and Alumina should not materially exceed 66%. Thus the P 0 may attain about 66% when B 0 and A1 0 are lacking.
  • the A1 0 ranges from O to a maximum of 16 percent.
  • PbO and/or BaO contain 9-13% of the group composed of PbO, BaO, and the other alkaline-earth oxides, PbO and/or BaO always being in preponderant amount.
  • PbO and/or BaO are preferred but a small percentage of them may be replaced by at least one other alkaline earth oxide, e.g. lime or magnesia.
  • alkali metal oxides for example, potassium oxide or lithium oxide.
  • a small amount of the alkali metal oxide eg. 5% calculated as Na O, may be replaced by ZnO.
  • the ratio of the total weight of alkali metal oxide (calculated as Na O) and ZnO to the total weight of PhD and BaO and other alkaline earth oxide is from 3 minimum to maximum.
  • the lead oxide may be kept below 5% if it isnecessary or desired.
  • Example 1 A mixture of 109.5 parts by weight of hydrated trisodium phosphate, 64 parts of monoammonium phosphate, 5.15 parts of red lead oxide, and 10.7 parts of barium carbonate are melted at about 900 C. in a silica crucible and pouredon'a table, producing a slightly opalescent glass without any tendency to devitrify. Its composition by weight analysis is:
  • composition of the vitrifiable mixture, and the analysis of the finished glass are given in the following table:
  • composition of the Vitrifiable Material Chemical Composition of the Corresponding Glass P B10; A120: PbO BaO ZnO N810 81.3 parts by weight of hydrated trisodium phosphate containing 22.1% by weight of P10 and 31.8% by weight of Nero.
  • the glass is pulverized by being ground, and it is then passed to a 55 screen, which has the openings between the wires measuring from .299 to .331 mm. on a side.
  • the glass which passes through the 55 screen is then passed to a 100 screen, which has the openings between the wires lying between .152 and .168 mm. on a side.
  • the material which remains upon the 100 screen is that employed in making the disc.
  • a stainless steel mold having a cavity 145 mm. in diameter and 3 mm. in depth was filled with such material.
  • the mold and its contents were introduced into an electric resistance furnace, where it was held at a temperature of 285 C. for minutes. Atthe end of that time the mold was withdrawn from the furnace.
  • the product thus treated in the mold was a disc made up of fritted grains, that is, the grains were bonded to each other but remaine distinct.
  • Example 2 The following batch is vitrified as in Example 1 but at 920 0.:
  • Example 1 Parts by weight After pulverizing to .l5-.30 mm. a disk 145 x 3 mm. was made and molded as in Example 1. Said disc was sintered at 440 C. in 25 minutes.
  • Example 3 g It being desired to extrude an aluminum alloy containing Cu 1.6 parts by weight,'Mn 0.2, Mg 2.5, Cr 0.3, Zn 5.6, a disk was made with a granulated glass containing by weight:
  • the disc After pulverizing to .15-30 mm. the disc was made and molded as in Example 1. Said disc was fritted at 370 C. in 25 minutes. The speed of drawing the alloy through the die, the plate made by fritting having been placed between die and ingot before the drawing, was 18 meters per minute. The product had no axial recess at the end and later thermal treatments showed no peripheral gross grains.
  • the alumina confers on glasses in accordance with the invention a hygroscopicity which decreases as the proportion of alumina increases.
  • the alumina raises the temperature of fritting and improves resistance to chemicals. and weather.
  • the lead oxide and baryta increase the fusibility.
  • alkali lowers the fritting temperature but we have found that an increase in alkali beyond the range indicated may produce products that tend to devitrify on cooling and even to produce pro-ductsthat vitrify with difiiculty.
  • P205+B20 50% minimum to 66% maximum.
  • PbO BaO other alkaline earth oxide Alkali metal oxide (calculated as NazO) ZnO Alkali metal oxide (calcu lated as N-a20) +Zn0--- Alkali metal oxide (calculated as NaeO) ZnO/ Pb0+BaO+other alkaline earth oxides 2/1 minimum to 3.5/1 maximum.
  • PbO+BaO are preponderant over other alkaline earth oxides, said other alkaline earth oxides may be 0.
  • a glass according to claim 11 in which a relatively small part of the percentage of BaO and PbO is replaced by magnesium oxide, and the ratio of weight of alkali oxide, calculated as Na O, to the total weight of BaO and PbO and MgO being between 2 and 3.5.
  • I 17 A glass according to claim 10 in which a relatively small part of the percentage of BaO is replaced by magnesium oxide, and the ratio of the weight of alkali oxide, calculated as Na O, to the total weight of BaO and MgO being between 2 and 3.5.
  • a glass according to claim 11 in which a small amount of alkali oxide calculated as Na O,- at most 5%, is replaced by ZnO, and the ratio of the total weight of alkali oxide, calculated as Na O, and ZnO to the total weight of BaO and PbO being between 2-and 3.5.
  • a glass according to claim 9 in which a small amount of alkali oxide calculated as Na O, at most 5%, is replaced by ZnO, and the ratio of the total weight of alkali oxide, calculated as Na O, and ZnO to the weight of PbO beingbetween 2 and 3.5.
  • a glass according to claim 10 in which a small amount of alkali oxidecalculated as Na O, at most 5 is replaced by ZnO, and the ratio of the total weight of alkali oxide, calculated as Na O, and ZnO to the weight of BaO being between 2 and 3.5.
