Introduction to some related issues of surfacing rolls
2021-09-15
Rolls are the heart of a rolling mill. The use of rolls involves mill selection, roll preparation, maintenance and regular dressing during the rolling process, which are factors that affect mill productivity, product quality and production economics. Since the rolling process is a continuous process, operators need to constantly check the condition of the rolls so that the product can meet the user's requirements for tighter tolerances and surface quality. In order to maintain the competitiveness of the products, it is necessary to constantly ask the mill operators to reduce production costs, i.e. increase the rolling speed, increase the production flexibility of the rolling mill and reduce the consumption of the rolls. So what should we pay attention to when surfacing rolls?
Some knowledge points of rolls
The cable tray equipment roll is an important part of the cable tray equipment. What are the characteristics of the design and use of cable tray equipment rolls? The design and use of cable tray equipment rolls have the following characteristics.
High-speed steel roll ring manufacturers: what are the commonly used high-speed steels and the advantages and disadvantages of high-speed steel
High-performance high-speed steel can be used to cut difficult-to-machine materials such as high-strength steel, high-temperature alloy, and titanium alloy by adjusting the basic chemical composition and adding other alloying elements, making its performance one step higher than that of ordinary high-speed steel. There are mainly the following:
High-speed steel roll ring manufacturers: common failure forms and causes of rolls
The roll is a tool for plastic deformation of metal (rolled material), and it is also an important wearing part that determines the efficiency of the rolling mill and the quality of the rolled material. Rolls are an important part of rolling mills, which use the pressure generated by a pair or group of rolls to roll and grind steel. It mainly bears the influence of dynamic and static loads, wear and temperature changes during the rolling process.
