Mold lubricant

Although more and more zinc sheet and strip are produced in continuous mills, some is stiU produced by rolling slabs cast in open or closed book-type molds made of cast iron (124—127). The casting temperatures are between 440 and 510°C, mold temperatures between 80 and 120°C. The contact surfaces of the mold must be smooth and clean to allow unrestricted shrinkage of the cast slab. Mold lubricant is not necessary, but if used should be held to a minimum. Slabs cast in open molds must be skimmed immediately to remove surface oxide. Rolling slabs are cast 1.87—10 cm thick. 

BN-powder is, due to its graphite-like properties, predestined for utilization as a high temperature lubricant or as a mold lubricant in metal casting. Formed articles of boron(III) nitride are used as melting crucibles for high purity metals or semiconductor alloys and as refractory linings for plasma burners, rocket jets and combustion chambers. 200 t/a of hexagonal BN were produced in 1995.

Soybean oil may be hydrolyzed into glycerol and fatty acids, or soybean oil soap-stocks (foots) may be acidified to produce fatty acids. Crude soybean fatty acids are used to make adhesive tape, shaving compounds, textile water repellents, carbon paper, and typewriter ribbons. Consumption of fatty acids in the United States, Western Europe, and Japan was 2.3 MMT (2.5 million t) in 2001. These soybean fatty acids can be separated into various fractions by distillation, and are used in candles, crayons, cosmetics, polishes, buffing compounds, and mold lubricants. These fatty acids can be converted to FAME by esterification, alkyl epoxy esters by epoxidation, fatty alcohols by hydrogenation (Kreutzer, 1983 Voeste Buchold, 1983), and dimer and trimer acids by conjugation or amines and amides as shown in Fig. 17.7 (Maag, 1983).
