Abstract

The invention discloses efficient cutting gas used for continuous casting and based on coke oven gas. The cutting gas comprises the coke oven gas and additive solution, wherein the additive solution is a mixture of copper naphthenate, methyl butyl ether, normal hexane, methanol, isooctyl glycollate and miscella No.200. The cutting gas can enable a gas appliance to have very good combustibility, safety and environmental friendliness, and has the characteristics of high combustion temperature, trim and smooth cutting face, small cutting slots and high cutting speed; meanwhile, no harmful gas exists when the cutting gas is used, so that human health is not harmed; and the metal yield is high.

Description

technical field [0001] The invention belongs to the technical field of industrial gas, and in particular relates to a high-efficiency continuous casting cutting gas based on coke oven gas and an additive liquid for continuous casting cutting gas based on coke oven gas. Background technique [0002] It has been more than 100 years since the French scientist Pirka first applied oxygen-acetylene to metal welding in 1903. Later, due to the high energy consumption, heavy pollution, easy explosion, high cost, transportation and Inconvenient storage and other problems, and in recent years, there have been many explosions and fire accidents in the production, transportation and use of dissolved acetylene. Therefore neither environmental protection nor economy. [0003] Since the 1970s, some developed countries in the world have begun to replace acetylene gas with new industrial gas. In the mid-1980s, the utilization rate of new industrial gas in the United States, Britain, Japan an...
