Surface blackening, surface phosphating, and surface nickel-phosphorus plating of steel parts
Blackening of Steel Surfaces
Steel surfaces can be blackened in order to reduce glare and smooth out the surface finish. This can be especially important if the steel is being used in a decorative capacity. Blackening can be done through methods such as hot dipping, cold dipping, chemical treatin......

Phosphorus eutectic type
Introduction
Grain boundary engineering is becoming increasingly important in modern materials synthesis and applications. It is critical to understanding the properties of materials and increasing their reliability, ductility, and corrosion resistance for various uses. One type of grain boundary......
Acid insoluble matter in powder
Unsoluble Acids in Powder
Unsoluble acids are substances that dissolve in water but cannot dissolve in organic solvents. They are found in many different types of powder including fertilizer, detergent, and propellant. Although unsoluble acids are not as dangerous as solvents, they do have some po......
Chemical composition of fluorite lump ore for metallurgy
Chemical Composition of Fluorspar Blocks for Metallurgical Use
The chemical composition of fluorspar blocks is an important property that must be assessed when selecting fluorspar blocks for metallurgical use. Fluorspar blocks give results in terms of the percentage of major elements, trace eleme......
Chain grate machine - rotary kiln roasting pellet method
Rotary Kiln Calcination Ball Method
Rotary kiln calcination is a process used to heat raw materials such as ores and other inorganic substances to very high temperatures in order to create particles of a desired size, shape, and chemical composition. The process involves heating a rotary drum, kn......
The Material of Horizontal Edge Roller in Section Steel Universal Rolling Mill
Introduction
Hydroforming and universal rolling mills, also known as levelers, are essential pieces of equipment for level rolling of plate material in the metals industry, such as steel plate, aluminum plate, and stainless steel plate. The levelers are used for equalizing the thickness of the sh......
The change law of PAG quenching liquid in use
Abstract
PAG oil is a transparent and colorless liquid, which is used in many industries. It has a higher boiling point, viscosity and low evaporating rate. In this paper, the changes in the use of PAG oil will be discussed.
Introduction
PAG oil, also called polyalkylene glycol oil, is a synthet......
Iron and steel room temperature phosphating technology
Introduction
The phosphating of steel at room temperature is a common process that is used to improve durability and improve corrosion resistance of steel surfaces. In this process, the surface of the steel is treated with a phosphoric acid solution to produce a protective film on the surface of ......
Metal heat treatment quality control
Metal Heat Treatment Quality Control
Heat treatment, or thermochemical processing, is an important process in metalworking. It is used to alter the properties of a metal such as hardness, ductility and strength. Heat treatment is widely used in various industrial processes such as automotive, pow......
