STABILISED FOR LONG PERIOD SUSPENSION FOR PLATING ON IRON MATERIAL AND TECHNOLOGY OF ITS MANUFACTURING Russian patent published in 2009 - IPC B22F1/00 C22B1/00 C09D1/00 

FIELD: metallurgy.

SUBSTANCE: invention can be used for prevention of engagement to each other pellets, particles or pellets manufactured from dolomite, magnesite, iron ore at its high-temperature processing. Suspension contains solid fraction approximately 52 - 61 %, water in amount approximately 39 - 48 %, not less than one anionic polyelectrolyte at concentration at least 25 % of dry mass in amount approximately 0.5 - 2.5 % and adhesive compound at concentration at least 30 % of dry mass in amount approximately 0.5 - 5.0 %. Viscosity of suspension is approximately 500 - 1500 centipoise, pH more than 10.5. In the capacity of solid fraction suspension contains particles with middle size 1 - 2.5 micrometres of hydroxide or magnesium carbonate or hydroxide or magnesium or calcium carbonate in amount 50 - 60 wt %. Equivalent content of magnesium oxide in solid fraction is 34 - 48 %, content of chloride - less than approximately 0.6 wt %.

EFFECT: stability of suspension at usage and storing during at least less than three months without essential blending and also well properties of adhesion with surface of pellets, particles and rolled briquettes and high area of coating.
