Development history of steel ball wear resistance

Looking back on a great development history of China's steel balls, it started almost at the same time as the reform and development. At the beginning of the reform and opening up, there was a huge gap between China's casting ball production and foreign advanced level. Most of the melting equipment used backward cupola. The product quality was poor, the production efficiency was low, the labor intensity was high, and the environmental pollution was not to mention. Sometimes it was a rare scene: sometimes father and son, sometimes a couple of friends, carrying a pair of peddler's shoulder, carrying a fan and a ball mold , walking through the streets. Enter a cement plant to negotiate a good price, use the scrap iron of the cement plant, look for two gasoline barrels in a corner of the plant, and a paste of refractory mud will become an earth cupola. Because the furnace bottom with a moving bar, commonly known as "monkey stove.". Fill in the coke and load the broken iron. The fan whirs as soon as the fan is connected. After a while, the red hot metal trickles out. The father and the son move the furnace and the spoon one by one. The hands and feet move together. The red iron flows into the black light ball mold with the sweat of the father and the son One by one, one by one, the iron balls with unclear chemical composition and even more uncertain performance came out of the furnace. After working hard for a few days, a good wine and a good meal accompanied by a sweet dream in the evening. In the early morning of the next day, the father and son, with hundreds of yuan of hard work from the cement plant in their arms, happily swam away to the house of hope in the rising sun This is a profile of the start of our steel ball production predecessors. Today's steel ball entrepreneur gene may have such inherited elements.

At the same time, with the rapid development of China's crushing industry after the reform and opening up, countless Chinese steel ball enterprises and steel ball "people" have made painstaking efforts to explore, work and create a global scale, cost-effective, highly innovative and Chinese characteristics, a huge modern steel ball industry, which has written a piece that can change the world steel ball history The history of China's steel ball making great efforts is a moving and colorful history.

As for the development prospect of steel ball, it is normal to have all kinds of predictions, among which "non spheroidization" of cement production is one of them. In fact, the vertical mill has many inherent advantages, especially in the energy-saving index. But it has been proved that the mode does not seek extreme but suitable, single technical index does not seek for comprehensive benefits and high rate of return, and various technologies and processes coexist and complement each other. It is an era of real competition and survival for enterprises to choose the technology and production mode suitable for their own development according to the conditions of the day, the time, the person and the place. The era of "non spheroidization" may be the narcissistic vision of the mill manufacturers and their interest spokesmen for at least a long time
