摘要： PURPOSE:To provide a lubricating oil which has high lubricity and stability, hardly brings about the deterioration by microorganisms and has excellent mill clean property, which comprises a product of esterification of a nitrogen- contg. polyol with a 6C or higher fatty acid. CONSTITUTION:1mol. of a nitrogen-contg. polyol of formula I (wherein X is H or CH3; n is 1-10) is esterified with at least 1.5mol. on the average of a 6C or higher fatty acid of formula II (wherein R is 5C or higher alkyl, alkenyl, hydroalkyl, or hydroalkenyl) to prepare an esterification product. This esterification product is optionally mixed with at least 1wt.%, mineral oil, emulsifier, fatty acid, antioxidant, anticorrosive, etc., to prepare a lubricating oil.

摘要： PURPOSE:To manufacture the titled steel strip having excellent phosphate treatability and surface cleanness, by cooling cold rolled steel strip after heat treatment, by aq. soln. contg. water soluble metal compd. and alpha-amino acid. CONSTITUTION:In continuous heat treatment of cold rolled steel strip in which it is heat treated, then cooled primarily or over age treated, and cooled secondarily, the strip is cooled primarily with aq. soln. contg. water soluble metal compd. and alpha-amino acid, further if necessary, cooled secondarily with aq. soln. contg. alpha-amino acid. Organic or inorganic compd. of Ni, Co, Mn, Zn, Cu, Cr, Mo, Ti, W, etc., is used as said metal compd., it is suitable to decompose it thermally on heated cold rolled steel strip to form about 1-100mg/m metal on steel strip surface. Amino acids of aliphatic cmpd., aromatic cmpd., heterocyclic ring state, etc., are used as alpha-amino acid, and as about 0.1-20% aq. soln. to remove oxide film.

摘要： PURPOSE:To reduce the thickness of an oxide film formed on a cold-rolled steel sheet during continuous annealing and to keep the surface appearance fine by adding an alpha-amino acid to primary cooling water and secondary cooling water when a cold-rolled steel strip is continuously heat-treated. CONSTITUTION:When a cold-rolled steel strip is continuously heat-treated in recrystallization heat treatment, primary cooling, overaging and secondary cooling stages, about 0.1-20% alpha-amino acid is added to primary cooling water and secondary cooling water. An aliphatic amino acid such as alanyl or arginine, an aromatic amino acid such as phenylalanine or tyrosine, or a heterocylic amino acid such as proline or histidine is used as the alpha-amino acid. About 0.001-0.5% surfactant such as lauroyl may be added furthermore.

摘要： PURPOSE:To manage lubricant quickly and accurately by employing a liquid chromatography infrared spectrometer to measure change of lubricant. CONSTITUTION:Component of lubricant will change chemically through actual usage to produce difference of molecular weight. Compound having carbonyl group, for example, separated in gel permeation chromatography mode to be separated by the difference of molecule size will select the infrared wave having highest sensibility in the region of 1,850-1,650cm through an infrared spectrometer to measure the peak. It can be managed through determination of target component.
