Problems solved by technology

Due to the large diameter of large gears, it is difficult to manufacture a heating furnace for its heat treatment. Even if such a large heating furnace can be manufactured, due to its large volume, it will waste a lot of energy and cause huge economic losses to the enterprise. The green remanufacturing of composite bimetallic large gears by surfacing welding is limited to a certain extent

Embodiment

[0010] The following disclosure is an embodiment of the present invention, and the chemical composition of the electrode coating is (wt%): rutile 2.4, marble 46.1, fluorite 21.5, quartz 2.7, clay 4.6, high carbon ferrochrome 2.8, high carbon ferromanganese 3.5 , ferrosilicon 2.6, titanium iron 8.8, molybdenum iron 5.2, cerium oxide 2.8, metal nickel 5. The welding core adopts H08A steel welding wire. The modulus of the binder water glass used is 2.9, and the concentration (Baume degree) is 49. For ferrosilicon, ferrochrome and ferromanganese, passivation treatment is required before use. The passivation process for ferrosilicon powder is 730°C, for ferrochrome powder is 560°C, and for ferromanganese powder is 320°C. Keep warm for 1 hour. Mix the relevant powders in the above formula with a mixer, then add water glass and stir evenly, extrude the welding rod with a welding rod coating machine, dry the welding rod at 280°C, and then grind the head and tail.

Abstract

A welding electrode for the build-up welding to manufacture large bimetal gear is composed of steel wire core H08A, adhesive (water glass), and welding agent prepared from rutile, marble, fluorspar, quartz, argil, high-carbon ferrochromium, high-carbon ferromanganese, ferrosilicon, ferrotitanium, ferromolybdenum, cerium oxide and nickel.

Description

technical field [0001] The invention belongs to the field of material science and engineering. Background technique [0002] Large gears are transmission parts widely used in metallurgical machinery, mining machinery, agricultural machinery, petrochemical machinery and other industries. In the traditional manufacturing process of smelting, casting, forging, heat treatment and machining, not only consumes a lot of energy, but also Seriously pollute the environment; even after decommissioning large gears still cause environmental pollution. Through green remanufacturing technology, it can restore its original shape and size, and improve its service life, thereby reducing energy waste and environmental pollution during its manufacturing process. [0003] Remanufacturing technology is to use original parts, adopt high-tech surface engineering technology and other processing technologies to restore the size, shape and performance of parts, form remanufactured blanks, and form re...
