STEEL SHEET WITH COATING BY ZINC ALLOY, APPLIED BY METHOD OF DIP GALVANISING INTO MELT AND METHOD OF ITS RECEIVING Russian patent published in 2010 - IPC C23C2/06 

FIELD: metallurgy.

SUBSTANCE: invention concerns coating field of hot dipping, particularly it concerns to steel strip with coating made of zinc alloy and method of its receiving. Steel strip is outfitted by layer of zinc alloy, applied by method of dip galvanising, herewith zinc alloy consists of: 0.3-2.3 wt % of magnesium 0.6-2.3 wt % of aluminium if necessary less < 0.2 wt % of one or more additional elements from Pb or Sb, Ti, Ca, Mn, Sn, La, Ce, Cr, Ni, Zr or Bi, unavoidable admixtures, and the rest is zinc and coating layer allows thickness 3-12 mcm. Inventions provide receiving of steel strip allowing coating by zinc alloy of minor thickness excluding bare spots with improved corrosion stability, formability of coating and well weldability, herewith more cheap than well-known coated steel strips.

EFFECT: method of obtaining steel strip with mentioned zinc alloy provides less formation of slag in pool with melt.
