In the early 1970s, China has been using the water jet coal process of 200bar pressure. The process of hydraulic topsoil stripping has been applied in Ximine for 100 years. Especially in the past decade, the rapid development of the high pressure water jet technology, the development of more pressure, higher flow products, to provide a necessary condition for the further application and promotion in the metallurgical industry.

High pressure cleaning machine is based on water as the working medium. Its working principle is mainly to pressurize ordinary purified water to hundreds or even more than one thousand atmospheres through a high pressure pump, and then to eject a highly concentrated energy jet beam through a small aperture high pressure nozzle, that is, we often say high pressure water jet. The high-pressure water jet has a high kinetic energy and is launched like a series of projectiles to hit various metal objects, generating the ability to peel and break, to achieve the purpose of rust removal. In addition, if you want to improve the efficiency of rust removal, an appropriate amount of abrasive can be added into the water jet to make the structure of the water jet change qualitatively and form the abrasive water jet, which can significantly improve the effect of the water jet.

For example, the high pressure washer of Zhejiang Horse Man Machinery Co., Ltd. is mainly used to deal with 1 ~ 5mm thick, 100 ~ 200mm wide strip, with an annual output of 20,000 tons. The abrasive selection of ferric oxide, its particle size is 1.6 ~ 0.074mm. In order to increase the viscosity and surface tension of the water jet, an appropriate amount of polyethylene oxide long chain polymer additive can be added to the water. After cleaning and derusting, the strip metal is worn off 0.02 ~ 0.04mm thick, and the metal surface is white and smooth. Compared with the traditional pickling, the cost of removing rust per ton can save more than 100,000 yuan, and the economic benefits are very considerable.

It can be seen that the use of high pressure washing machine to replace the traditional metal rust removal production mode and technology, can greatly improve labor productivity, reduce production costs, improve workers' working conditions, and obtain significant economic and social benefits.
