Embodiment 1

[0016] Example 1: A total of 5 rolling periods were collected and tracked. Through tracking and testing, the quality of the roll surface, the actual rolling stability, and the surface quality of the strip steel were all very satisfactory, and there were no scale defects in the roll system. In addition, the shape control Stable, no abnormality occurs, and the expected effect is achieved.

[0017]

Embodiment 2

[0018] Example 2: A total of 4 roll periods were collected and tracked. Through tracking and testing, the quality of the roll surface, the actual rolling stability and the surface quality of the strip steel were all very satisfactory, and there were no scale defects in the roll system. In addition, the shape control Stable, no abnormality occurs, and the expected effect is achieved.

[0019]

[0020] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0021] The method of using the high chromium cast iron roll provided in the embodiment of the present application is specifically to grade the roll surface of the high chromium cast iron roll after it is off the machine for the first time. The method reduces the grinding quantity and production cost of rolls, and eases the pressure of roll preparation; at the same time, in order to minimize the risk of strip surface quality problems, it ...

Abstract

The invention belongs to the technical field of hot rolling processes and discloses a using method of high-chromium cast iron rollers. The method comprises the steps that the stopped high-chromium cast iron rollers with the roller face level being two or above are started for use for the second time, and a rack F1 or F2 is used. Through the using method of the high-chromium cast iron rollers, the roller consumption and using cost can be reduced, and the production efficiency and product quality are improved.

Description

technical field [0001] The invention relates to the technical field of hot rolling and rolling technology, in particular to a method for using a high-chromium cast iron roll. Background technique [0002] In order to meet the demand of the steel market, it is necessary to complete the task of receiving orders with multiple varieties and extreme specifications, which will inevitably lead to a short roll period and an increase in the number of roll changes, which will have a greater impact on various cost-related indicators such as roll consumption. On the other hand, when there is a shortage of rolls and the shortage of spare rolls occurs, the high-chromium cast iron rolls are used on the machine at one time, which is inefficient and further increases the risk of waiting for rolls on the rolling line. Contents of the invention [0003] The invention provides a method for using a high-chromium cast iron roll, which solves the problems in the prior art that when the productio...
