The niobium solute acts to drag and prevent grain coarsening
Introduction
Niobium is a transition metal that shows useful properties in many different applications. It is often used as an alloying agent for steels, for example in superalloys, corrosion-resistant alloys, and high-speed steels, some of which contain up to 6% niobium. In its pure form or as a......

Titanium-aluminum intermetallic compound investment shell mold casting process
Analysis of Titanium Aluminum Intermetallic Alloy Shell Casting Process
Abstract
Titanium alloys are increasingly used in the manufacture of structural components, such as aircraft structural parts, and titanium aluminum alloys are attractive due to their excellent mechanical, physical and chemi......
Basic Physical and Chemical Properties of Continuous Casting Mold Flux
Introduction
Continuous casting protection slag is a kind of powder slag produced by steelmaking process. It is composed of a mixture of iron oxide, calcium oxide, silicon oxide and aluminum oxide. Generally, the slag produced in the steelmaking process can be divided into two kinds, one is molte......
The role of molten steel and refractories in continuous casting
In continuous casting, steel liquid and refractory materials play a very important role. Refractory materials are essential to continuous casting, and the quality of their performance directly affects the quality of continuous cast billets and the normal production of the plant.
The role of refra......
Subcutaneous Bubbles of Continuous Casting Slabs
Subsurface Porosity in Continuously Cast Slabs
The importance of porosity in continuously cast slabs is often underestimated and should not be overlooked. Porosity can act as a stress accumulation zone, render the outer coating of the slab prone to failure, and cause defects such as cracks. Subsu......
Composite particle passivation magnesium for hot metal pre-desulfurization
Compound Particles of Magnesium Used in Steel Desulfurization
In the steel desulfurization process, the use of compound particles of magnesium has been increasingly used in recent years due to their high efficiency in desulfurization process. The compound particles are usually called dried magnes......
Improving Steel Cleanliness by Controlling Slag Composition
Introduction
Steel is an important industrial material. It has a wide range of applications and plays a significant role in every aspect of our lives. However, its quality is affected by the content of slag inclusions. To maintain the high quality of steel, the content of slag inclusions must be ......
Characteristics of dephosphorization and desulfurization in top-blown converter blowing process
Desulfurization and Dephosphorization Characteristics in the Process of Top Blowing Converter
Introduction
Removing sulfur and phosphorus from molten iron is a major task in the metallurgical industry. The top blown converter is an important tool for steelmaking, used to desulfurize and dephosph......
pressure leaching
Leaching is a process by which metals are extracted from their ores using a liquid solvent. In the process of leaching, the ore is placed in a vessel with a liquid solvent and the particles of the ore dissolve in the solvent. The resulting solution, containing dissolved metals, is called a leachat......
Carbonate dissociation pressure-temperature diagram
Carbonate ion dissociation pressure-temperature diagrams are diagrams which graphically illustrate the dissolution characteristics of various carbonate minerals and their molecular ions (CO2 and CO2 3-) across a wide range of temperatures and pressures. The diagram provides a way to predict how a ......
