Billet cutting flame cutting instead of mechanical shearing method has become a trend. For production of coke oven gas steel companies, the use of coke oven gas is used to cut the use of lower cost slab. Do not have the coke oven gas, coke oven gas or low pressure, gas purity is not enough business, they use an acetylene or propane (en) and other gas for billet cutting.

  Oxyacetylene flame temperature is high, the heat value is large, but the high cost of their production and use, the presence of the use of unsafe, pollution and other problems at the same time. In addition, the high slab temperature (1073K or more), the heating value of the gas is not high, the best is not a slab of acetylene gas cutting. Propane or propylene gas for slab cutting, to a certain extent, reduce the cost. These are bottled in the form of gas supply, the higher the presence of cost, inconvenience, insecurity, pollution and other issues.

  Water electrolysis hydrogen generator for slab cutting, the equipment is simple, easy to operate, as long as power and water, the use of low pressure gas is not stored with the production with use, equipment accident rate, low maintenance, low cost, safe and reliable; hydroxide flame concentrated, less circumcision, cutting quality, cutting surface smooth and easy to clean and less dross; odorless toxic hydrogen to produce water after combustion, no environmental pollution.
