Crystallizer
The crystallizer is a very critical component in continuous casting equipment. In the solidification process in which the molten steel is injected into the crystallizer to gradually form the thickness of the shell, the crystallizer is required to have good heat conduction, cooling ability and wea...Read more -
Characteristics of LF furnace Refined Steel
1 LF Furnace Atmosphere The LF furnace performs molten steel refining treatment under normal pressure, and the water-cooled furnace cover can serve as a sealing function for separating air. When heated, the graphite electrode reacts with oxides such as FeO and MnO in the slag to form CO gas, whic...Read more -
Feasibility Analysis of Blast Furnace Slag Injection Technology
1、Prerequisites for Blast Furnace Slag Injection The catalytic effect of converter slag is suitable for coal with low volatile content. At present, the domestic coal for blast furnace injection in China is basically mixed coal, with a volatile content of about 15%. At the same time, the oxygen e...Read more -
Harm of Oxygen, Nitrogen and Hydrogen to Steel Products
1、Harm of Hydrogen When the hydrogen content in steel is greater than 2 ppm, hydrogen plays an important role in the so-called "flaking off" phenomenon. When internal cracks and fractures occur during the cooling process after rolling and forging, this spalling phenomenon is generally more obvio...Read more -
Brief Introduction of Fast Temperature Measuring Thermocouple
Use and Working Principle of Rapid Temperature Measuring Thermocouple The rapid temperature measuring thermocouple is used to measure the temperature of molten steel and high temperature molten metal. It is a one-time consumption type thermocouple. Its working principle is to measure the temperat...Read more -
Rolling mill starts energy saving and environmental protection route in the future
The flywheel of the rolling mill is subjected to impact load during rolling. The rolling mill drives the rolling mill through the flywheel and reducer. A part of the load is released by the flywheel. The main drive of the rolling mill requires high dynamic response and high overload capacity. Fly...Read more -
Hot Rolling Theory
By definition, ingot and billet at room temperature is very difficult to deformation, not easy processing, general rolling heating to 1100 ~ 1250 ℃, the rolling technology called hot rolled. Hot end temperature is 800 ~ 900 ℃, generally in the air after cooling, and hot rolling state is equivalen...Read more -
Difference between Cold Rolling and Hot Rolling
The difference between cold rolling and hot rolling is mainly the temperature of rolling process. "Cold" is normal temperature, "hot" is high temperature. From the viewpoint of metallography, the boundary between cold rolling and hot rolling should be distinguished by recrystallization temperatur...Read more
