A kind of electroless cutting flux used for rapid cutting of metal workpiece and cutting pen containing the flux

Abstract

The invention relates to a nonelectric cutting welding agent for rapid metal workpiece cutting. The welding agent is formed by mixing 70-86% of powdered thermite, 9-16% of slag former, 3.5-11.5% of alloying agent and 1.5-7.5% of gas making agent. The nonelectric cutting welding agent has the advantages that an cutting material which can conduct cutting without outer energy sources or equipment is provided, a bar with the diameter phi of 15 mm or a metal workpiece with the thickness smaller than 5 mm serves as an cut target of the welding agent and a cutting pen, an outer power source and an outer gas source are not needed, carrying is convenient, operation is easy, and the nonelectric cutting welding agent is suitable for outdoor emergency repairing; the welding material can adapt to wider environment temperatures, can be used for welding within the temperature range from minus 55 DEG C to 40 DEG C and is more suitable for the outdoor emergency repairing environment. The components and matching of the welding agent are integral, and the effect of the welding agent will be changed by changing any component or the content of the component.

Description

technical field [0001] The invention relates to the field of emergency cutting, in particular to a Non-electric cutting materials for rapid cutting of metal workpieces such as bar or low-carbon steel with a thickness of less than 5mm. This material is based on combustion synthesis technology, and realizes non-electric emergency cutting through the combustion synthesis reaction of welding powder. Background technique [0002] When the bolts, pins, bushings and other workpieces of the equipment are welded, seized and other faults need to be repaired, the most commonly used method for quick disassembly is cutting; in addition, in the event of serious disasters such as fire, earthquake, and building collapse, cutting It is one of the necessary means for rush repair and rush construction. However, when working in the field, the existing demolition and cutting tools have problems such as large equipment, poor mobility, power supply and air source, etc., so that they cannot be fl...
