Oxy-hydrogen flame cutting technology | Green cutting solution for continuously cast slabs
Using water as the raw material, oxy-hydrogen mixed gas is generated on site by water electrolysis (produced and used immediately, never stored), replacing fossil gases such as natural gas and propane for energy-saving, low-carbon green cutting of continuously cast slabs.
The system operates below 0.1 MPa and comes standard with leak and overpressure interlocks for high safety. The only combustion product is water, with near-zero smoke and harmful gases, markedly improving the working environment of the continuous casting area.
The product line ranges from HGQ-1000 to HGQ-20000A (gas output 1,000 L/h–20,000 L/h) and accommodates a wide variety of specifications — carbon steel, special steel and stainless steel, as well as continuously cast billets, blooms, slabs and rounds.
Measured fuel costs are about 89% lower than with natural gas (per ton of steel equivalent), substantially reducing operating costs.
Produced and used immediately, operating below 0.1 MPa with standard leak/overpressure interlocks — safe and controllable.
Average kerf width ≤ 4.5 mm and cutting success rate ≥ 99%, with a smooth cut surface, no molten edges and easy cleaning.
CO₂ emissions are reduced by about 0.36 kg/t — up to 8,758 tons per year. The only combustion product is water, and smoke is almost zero.
Designed for the online cutting of continuously cast slabs in the steel industry, it fits blooms, slabs, rounds and other cast types and supports carbon steel, special steel and stainless steel grades. Beyond online continuous-casting cutting, it is also applicable to multi-station heavy-plate cutting, metallurgical heating and other scenarios; the smaller models (HGQ-1000–3000) can additionally be used for precious-metal processing, ampoule sealing and sheet cutting.
Key specifications: Flame temperature: 2,800–3,000 °C. Cutting capacity: rounds up to Φ600 mm, blooms 410 mm, slabs (offline) 530 mm and stainless steel 220 mm. When switching from natural gas, the kerf width narrows by about 40% from 6.5 mm.
Track record: Baosteel Zhanjiang (carbon steel slabs): South Zone No. 3 and No. 4 continuous casters, kerf width ≤ 4.5 mm, cutting success rate ≥ 99%, power consumption < 0.28 kWh/t of steel.
