Unqualified Reasons And Solutions Of Cold Rolled Ribbed Steel Bars Heating 


What are the unqualified reasons of cold rolled ribbed bars heating and what are the solutions? As a professional manufacturer of cold rolled ribbed steel machine and cold rolled ribbed steel production line, Gongyi Jindi Metallurgical Equipment Co., Ltd  will explain the unqualified causes and solutions of cold rolled ribbed steel bars heating in the following.


1. There is a color difference of the cold rolled and ribbed steel bars caused by the heating temperature being too high or too low, that is, the colors are different, and the specific performances are as follows:


A.When the heating temperature is too low, the colour of cold rolled steel bar will be purple;


B.When the heating temperature is low, the colour of cold rolled steel bars will be green and blue;


C.When the heating temperature is too high, the colour of cold rolled steel bars will be dark and gray.


So how do you solve the chromatic aberration of the cold rolled ribbed bars after heating? The technicians of the cold rolled ribbed steel production line from Gongyi Jindi Metallurgical Equipment Co., Ltd. believe that only need to add an infrared thermometer to monitor the temperature of the heated cold rolled steel bar at any time.


2. When the raw material meets water, the color of the cold rolled ribbed steel bars is dim. The surface of the ribbed steel bars has black dirt that can be scraped off, and it also affects the descaling operation of the raw material.


Solution: The base metal must be dried before heating. Otherwise, due to the high temperature and high humidity during the heating process, a thin layer of iron red will be generated instantaneously. The overall visual appearance of the product will become red, and many red powders will be found on the surface.


The reasons for the unqualified heating of cold rolled ribbed steel bars and the solution are the above two points.
