Description

technical field

[0001] The invention relates to the field of emergency cutting, in particular to a directional cutting device for steel components. Background technique

[0002] Emergency cutting is an important technology for emergency installation, repair and dismantling of field engineering facilities and equipment, and it is also an indispensable technology for army battlefield repairs. Statistics show that equipment parts are stuck, broken, perforated and other damages in the field or on the battlefield, which affect the performance of the equipment. Most of them need to be quickly solved by emergency cutting. In earthquake, snow disaster, landslide, shipwreck and other disaster rescues and daily fire rescue, there is an urgent need for a portable and safe emergency cutting method.

[0003] At present, the commonly used thermal cutting methods in field repairs are plasma cutting or gas cutting. Plasma cutting is a thermal cutting method that uses high-energy density, ...
