Abstract

The invention discloses an oxygen lance modified from an accident cutting handle, belonging to the field of machinery, and aiming at solving the problem that conventional oxygen lances used for punching holes in continuous casting are easy to have the accident of tempering which causes injuries to operators,. The oxygen lance comprises an oxygen burning pipe, a seamless pipe, a switch button and a cutting handle. A fuel gas port and a sealed high-pressure oxygen port are arranged on the rear end of the cutting handle and a mixed gas port is arranged on the front end of the cutting handle. The cutting handle is paralleled to the seamless pipe, and female threads connected with the mixed gas port of the cutting handle are arranged on the wall of a cylinder at the rear part of the seamless pipe. The switch button is arranged on the rear end of the seamless pipe and the front end of the seamless pipe is connected with the oxygen burning pipe. The invention modifies the waste accident cutting handle to be an oxygen lance used for punching holes in continuous casting and the oxygen lance effectively avoids the accident of tempering. The oxygen lance is convenient to be used for handling accidents, ensures the safety of the operators and is convenient to use. The invention makes use of waste equipment to make new devices and makes reuse of the residual value of wastes, thus saving costs for enterprises.

Description

technical field [0001] The invention relates to an accidental cutting handle to burn an oxygen lance, and belongs to the field of machinery. Background technique [0002] Oxygen lances are often used in the continuous casting or production process. The existing continuous casting oxygen lances for eye burning use a rubber tube connected to a thin oxygen tube. In the event of a flow accident, the oxygen burner is prone to backfire, resulting in injury. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing oxygen burner used for continuous casting is prone to backfire, resulting in injury. Provided is an accident cutting handle to burn an oxygen gun. [0004] The accidental cutting handle of the present invention is changed into an oxygen gun, which includes an oxygen burning tube, a seamless pipe, a switch button, and a cutting handle. The rear end of the cutting handle has a gas interface and a sealed high-press...
