Abstract

The invention introduces a surfacing welding electrode for the manufacture and repair of sucrose rolls, which adopts CaO-CaF2-SiO2 alkaline slag system, and the welding core adopts H31Cr13 welding core; the composition of the coating is: marble: 20~30%, fluorite: 12 ~18%, rutile: 1~3%, carboxymethyl cellulose: 0.5~2%, flake graphite: 1~5%, 75° ferrosilicon: 2~4%, phlogopite: 1~3%, high Carbon ferromanganese: 1~3%, high carbon ferrochromium: 38~44.5%, titanium ferro: 2~4% quartz: 1~3%, aluminum magnesium alloy: 0.5~2%. The electrode arc of the present invention is easier to ignite and burns smoothly; the coating is evenly melted with less splash; The grinding coating has good wear resistance and corrosion resistance, which can facilitate the regular maintenance of the sugar roll and greatly prolong its service life.

Description

technical field [0001] The invention relates to a welding material technology, in particular to a surfacing welding electrode for manufacturing and repairing sucrose rolls. Background technique [0002] The sucrose roll is a main equipment in the sugarcane sugar making equipment. Due to the harsh environment and easy wear and tear, most of the rolls will be unable to continue to be used due to wear and failure after a cropping season, and a few rolls will not be able to be used due to wear and tear during the production process of a cropping season, resulting in a production stop and causing heavy losses. At present, a roll made of cast iron has been developed, which saves labor time and cost compared with other alloys, and also provides the best compressive strength and is easy to weld. The surface of this roll needs to be welded with wear-resistant coating, which can be repaired regularly to prolong the service life. At present, there are many types of surfacing electrod...
