Hydrogen-oxygen cutting technology for continuous casting billets

Recently, Panshi Jianlong introduced fully automatic hydrogen-oxygen cutting technology and successfully applied it to the cutting production of continuous casting machine billets. After the introduction of the new technology, the company will save 80% of propane gas usage and 40% of oxygen usage each year, laying a solid foundation for building a green and low-carbon enterprise.

In recent years, Jianlong Group has deepened the green and low-carbon development strategy, and clarified six green and low-carbon development paths, including process optimization and improvement, cutting-edge technology innovation and application, product green and low-carbon transformation, energy efficiency structure optimization, green logistics system upgrade, and resource energy recycling.

Before the introduction of hydrogen-oxygen cutting technology, Panshi Jianlong used traditional propane gas for billet cutting, which not only had the disadvantages of high energy consumption, high slag, uneven cutting section, and large cutting smoke pollution, but also affected the production quality of subsequent processes. In response to the above pain points and difficult problems, the company finally decided to introduce clean energy gas as cutting fuel through multiple discussions, and hydrogen-oxygen cutting technology, which mainly uses hydrogen-oxygen mixed gas generated by water electrolysis as fuel, is an environmentally friendly and efficient cutting method.

Compared with traditional propane gas cutting, this technology has many advantages.

1. Eliminate safety hazards.

Introducing new energy to replace traditional propane cutting can reduce the number of propane gas cylinders stored on site and eliminate the safety hazards of large propane gas cylinder storage.

2. Achieve low carbon emissions.

Because the combustion product of hydrogen-oxygen cutting is only water, there is no carbon dioxide emission, which can effectively reduce cutting smoke and improve the working environment. It can reduce the use of propane gas by 80% each year, and it is estimated that carbon dioxide emissions can be reduced by about 230 tons.

3. Improve cutting quality.

Hydrogen-oxygen cutting has smooth and flat incisions, and there is less cutting residue on the lower surface of the ingot, which helps to improve the quality of subsequent process products.

4. Improve the degree of automation.

From the start of gas generation to the end of cutting, the whole process is automatic, without the need for human operation, reducing the labor intensity of employees.

The successful application of fully automatic hydrogen-oxygen cutting technology is a typical demonstration of the effective use of clean energy in the metallurgical industry, marking that Panshi Jianlong has taken a more solid step in the application of cutting-edge technologies such as taking local conditions into account, reducing pollution and carbon emissions, and extreme energy efficiency.
