metal cleaning agent, mostly used for heat treatment and chemical heat treatment of heat-resistant steel precision castings before cleaning.

　　Heat-resistant steel precision casting is one of the castings. Cleaning of heat-resistant steel precision castings is divided into general cleaning, ultrasonic cleaning, degreasing cleaning, and vacuum cleaning. They have their own characteristics, the formulation of the cleaning solution used is different, general cleaning agents have solvent-based cleaning solution (there are two types of petroleum solvents and organic solvents, not widely used) and aqueous cleaning solution (alkaline cleaning agents and surfactants, etc.), in the practice of heat-resistant steel precision castings cleaning process, more than selected are.

　　1, metal cleaning agent, mostly used for heat treatment and chemical heat treatment of heat-resistant steel precision castings before cleaning.

　　2, 3%-10% sodium carbonate or sodium hydrogen radonide cleaning solution, temperature control at 80-100 ℃, mostly used for the quenching of heat-resistant steel precision castings after the oil removal, salt slag finishing.
