Abstract
Advantages of flux-cored strip application as electrode material for wear-resistant surfacing are considered. The list of batch-produced flux-cored strips, their typesizes and form of delivery is given. Examples of techniques of strip application for surfacing cones and cups of blast furnace charging equipment, pans of coneless charging devices, beaters of coal-pulverizing mills, cutters for hot cutting of metal, and production of wear-resistant bimetal sheets are presented. Kinds of new specialized equipment for surfacing with flux-cored strips are shown, namely A1812M apparatus for surfacing cones and cups of blast furnace charging equipment, AD 380.03 unit for plate surfacing, UD298M unit for surfacing cutters for hot cutting of metal. All the equipment is fitted with control systems based on microcontrollers. Enterprises, where new developments have been introduced, are listed. 8 Ref., 1 Table, 6 Figures.
