Application of RH Top Blowing Oxygen Technology
Introduction
Rh top-blowing oxygen (RHB) technology is a process technology in which oxygen or oxygen-rich gas is blown onto the surface of the molten steel to reduce the concentration of carbon, hydrogen, nitrogen and other harmful elements in molten steel. It is a new type of process technology......

Hollow steel for rock drilling rods (GB/T1301—1994)
Hollow steel, also known as hollow steel, is a kind of steel cross section made of uniform thickness rolled and welded steel, which is also called divided steel. It is an iron and steel material with different shapes and wall thicknesses. It is mostly used for steel columns, steel beams, steel sca......
20CrMn use
20CrMn is a kind of alloy structural steel, and its mechanical properties greatly exceed that of ordinary structural steel. It is used for important parts in various machines, and its performance is very positive for engineering machinery structures.
First of all, the most important use of 20CrMn......
32SiMn2MoV application
P20/30SiMn2MoV is a common steel of medium carbon and low alloy steel, belonging to the Cr-Mn-Mo series tool steel, a common type of high-strength steel. It is punch-press die, trimming die and measuring tools, large and medium-sized plastic mold and core parts with high working surface wear resis......
40Cr, 45Cr use
40Cr and 45Cr
The term “Cr” in metals stands for chromium and is used in many alloys and compounds, such as steel and other metals. Two of the most common chromium alloys are called 40Cr (or 40 Chromium) and 45Cr (or 45 Chromium). While chromium does have many uses, here we will focus specifica......
42CrMo use
42CrMo steel is a Chinese alloy steel, and has high strength and toughness, good hardenability, no obvious temper brittleness, good fatigue limit and repeated impact resistance after quenching and tempering, and good low temperature impact toughness. This material also has strong metallurgical sta......
