Overview of the development of the roll industry
The steel industry covers a wide range of areas, has high industrial correlation, and is driven by consumption. It is an important pillar industry of my country's national economy and plays an important role in economic construction, social development, finance and taxation, national defense construction, and stable employment. Through several generations, the steel industry Through the efforts of steel practitioners and after decades of construction and development, the achievements of my country's steel industry are enough to attract the attention of the world, and a steel industry system with relatively complete categories and a relatively complete structure has been formed. In 1996, my country replaced Japan as the world's largest steel producer for the first time with an annual output of 101 million tons of steel. Currently, China is one of the most important producers in the global steel industry, accounting for more than 50% of global steel production.
The final product of the steel industry is steel. The rolling and forming of steel is inseparable from the roll industry. The roll manufacturing industry has made a huge contribution to the rapid development of the steel industry. As the main consumable part of the rolling mill, the consumption cost of the roll is about 5%-10% of the steel rolling production cost. It is directly related to the production efficiency, production cost and surface quality of the rolled material of the steel rolling enterprise. It is indispensable in the rolling process of the rolling mill. A key component, known as the "Mother of Steel".
