The basic principle of phosphating - phosphating classification
Phosphatization Classification
Phosphatization is a method of chemically treating a material, such as metal, to form a protective layer of phosphate, also known as PTZ (Patina, prophylactic, zinc or PZ). It is the combination of a metal surface and phosphorus in an acid or alkaline solution, and ......

The basic principle of phosphating - pretreatment before phosphating
Phosphating is a process in which a series of salts are applied to metal surfaces to improve their rust protection and painted surface adhesion. In order for phosphating to be effective, proper surface preparation must take place prior to its application. This includes ridding the metal surfaces o......
Introduction to the formula of water-soluble quenching liquid (1)
Water-soluble Quenching Liquid
Water-soluble quenching liquids are used in the quenching process of metals, which refers to annealing, hardening, and other heat treatment processes to improve the physical properties of metal materials. In the annealing process, water-soluble quenching liquids are......
Influence of deoxidation method on the quality of continuous casting slab
The Impact of Dephosphorization on the Quality of Continuous-Casted Slab
1 Introduction
High-phosphorus steel is a common steel in steelmaking. Phosphor is one of the elements that affects the strength, hardness, plasticity and other mechanical properties of steel. The presence of phosphor impai......
Continuous casting cooling water treatment
Ladle Cooling Water Treatment
Ladle cooling water is a key process for castings during production in metallurgical plants, and its water quality requirements are also very high. If there are problems such as serious scale, excessive corrosion and water quality instability in ladel cooling water, ......

Deoxygenation
Deoxygenation is the process of removing oxygen from a compound or system. It can have different applications depending on the substance and environment in which it is being removed from. Deoxygenation can be used to improve the quality or yield of products, reduce environmental im......
Formation of foamy slag and its influence on blowing and its control
Formation of Slag and Its Impact on Blowing and Control
Slag is a material that is produced when certain ores are melted and the impurities are separated. It consists mainly of oxides of phosphorus, silicon, aluminum, iron and magnesium, and solidifies in the furnace, forming a layer on the air f......
