What Types of Rolls Are Used in Rolling Mills?
There are many different specifications and materials for rolling mill rolls, such as forged rolls and centrifugal casting rolls. Casting rolls are divided into high, medium and low nickel. Because the classification and use of rolls are complicated, we mainly analyze the quality indicators of different rolls used in rolling mills.

Classification of Continuous Steel Leakage Accidents and Analysis of Some Causes
The so-called steel leakage refers to the phenomenon that the solidification of the billet shell is not good or the billet shell is broken or leaked due to the action of other external forces, causing the internal molten steel to flow out during the continuous casting or the casting process. Steel leakage is one of the vicious accidents in continuous casting production. Serious steel leakage accid...

Can Rolling Mill Lubricant Reduce Rolling Force and Power Consumption?
The working rollers and bearing roller bearings of rolling mills are generally lubricated with dry oil, and oil film bearings and oil mist, oil gas are used to lubricate at high speeds. The gearboxes of rolling mills, motor bearings, and reducers in electric pressure devices use thin oil circulation lubrication.

Continuous Casting Process
Continuous casting is the intermediate link between steelmaking and steel rolling, and is an important part of steelmaking plant (or workshop). The technological process of continuous casting production is: ladle → tundish → crystallizer → secondary cooling → straightening of billet → cutting → roller conveyor → steel pusher → casting billet.

The Reason and Solution of Steel Piling
The reasons for stacking steel between racks of wire rod mills are: Guide sticks steel; The guide wheel does not rotate or the bearing burns out; Splitting of rolled parts; The guide or roller ring is installed incorrectly; Improper setting of roll gap or unsatisfactory incoming material size;

Roller Requirements for Roll Performance and Transformation
The components of the bar rolling machine are rough rolling, intermediate rolling, and finishing rolling. The finishing rolling unit mainly shrinks the steel slab at a high temperature. The rolling force is large and the rolling speed is low. Generally, the roller is required to consider the strength of the roller and the hot crack resistance. At the same time, certain abrasion resistance is requi...

What Are the Connection Devices for Rolling Mills?
The connecting shaft is a device that transmits power from the gear seat to the rolls, or from the rolls of one rolling mill to the rolls of another rolling mill, or directly from the main motor to the rolls. There are two types of universal connecting shafts: universal joint shaft and plum blossom shaft.
