Norton help China's rail transit safe and efficient operation

On May 23, the high-speed maglev test prototype was off the assembly line in Qingdao. 600 km/h! Shock your imagination.

Taking Beijing to Shanghai as an example, plus preparation time, it takes about 4.5 hours to fly by plane, about 5.5 hours for high-speed rail, and only about 3.5 hours for high-speed maglev. Soon, the speedy experience of passengers flying on the ground is just around the corner.

The rapid development of China's rail transit has already astounded the world again and again, and it is a great engineering miracle.

This ambitious project is also the result of cooperation between countless people and a miracle of cooperation. Being able to participate in this cooperation that changes people's lives, Mobao is also working hard!

3 months to complete new product development to provide test samples

Mass production in 6 months

Shorter delivery time by 70%

This is the speed of Saint-Gobain Abrasives to help China's rail transit!

The new product development cycle in the industry often lasts for several years. Saint-Gobain Norton only provides test samples in 3 months, and mass production is completed within 6 months. The product quality is excellent and cost-effective, and the delivery time is shortened by 70%.

During the operation of the railway, the surface of the rail will gradually produce small cracks or pits. The rail grinding can effectively remove these surface defects and prevent micro-duration, which effectively guarantees the safety and economic operation of railway traffic.

At present, the traditional method of rail grinding is maintenance-based low-speed grinding. After the defects are discovered, the grinding wheel will be polished along the rails at a speed of 20 km per hour.

In recent years, an innovative high-speed preventive polishing program has become popular, with a speed of up to 80 kilometers per hour.

This brings a number of benefits, including extending rail life, reducing overall grinding costs, and because of the increased speed, the operation of the grinding car will have less impact on the normal operation of passenger and freight trains.

 However, a higher speed means that the grinding wheel under the grinding car needs to withstand a greater test.

After increasing the speed by 3 times, the grinding time of the grinding wheel is shortened by 3/4 for the same length of rail, so it is necessary to have a higher material removal rate, and the grinding wheel itself needs to withstand greater pressure to avoid breaking.

For subsequent high-speed trains, the debris on the rails is quite dangerous.

Vossloh is a leading global railway service provider that produces high-speed grinding wheels in Europe.

When they plan to expand their business to China and the Asia Pacific region, the first thing to do is to find local grinding wheel manufacturers as strategic partners. The research and development capabilities, delivery time and cost-effectiveness of the grinding wheel manufacturers are extremely important to the success of their localization business.

Saint-Gobain Abrasives has earned the trust of its customers with its local production, R&D and service capabilities.

In the abrasives industry, developing a new wheel and providing test samples can take years, and batch production and fast delivery in a few months can be a daunting challenge.

At this point, we faced the challenge and worked side by side with Vossloh Foslo to develop a new wheel product for its polishing car.

With our strong local R&D capabilities and production capacity, as well as a wealth of expert resources, we have delivered Norton®-Vossloh grinding wheel samples in just 3 months.

After Vossloh's multiple rounds of rigorous testing, the samples fully met the performance targets and met their cost targets.

In six months, the Norton®-Forsrow wheel was mass-produced and delivered quickly. Due to the local production of the grinding wheel in China, the delivery time is 70% shorter than the original European supplier of Forslow.

The high-speed rail grinding machine equipped with Norton®-Forsrow wheel is advancing at full speed on China's railways, and the company's business in China is also experiencing rapid development.

We also use this as a starting point to develop a new generation of higher performance products for the high-speed rail polishing market, and plan to build a special high-speed rail grinding experiment platform.

As the world's leading supplier of grinding solutions, as a participant in China's rail transit construction, we will always be a reliable partner for our customers. For the development and speed of China Railway, we are always with our customers!
