Description

A kind of quenching medium containing rosin and preparation method thereof

Technical field

The present invention relates to heat treatment technics, be specifically related to a kind of quenching medium containing rosin and preparation method thereof.

Background technology

In treatment production, quenchant directly affects the performance after parts quenching, is the key factor affecting quality product.Conventional quenchant mainly contains water, the aqueous solution, wet goods, and wherein quenching oil is big for environment pollution, and fire hazardous during quenching, security, the feature of environmental protection are difficult to reach requirement.

Water is the quenchant that cooling power is stronger, and its source is wide, price is low, stable components is not perishable.Shortcoming is that in process of cooling, workpiece easily produces " soft spots ", and in martensite transformation temperature district because cooling is too fast, easily produces very large internal stress, cause workpiece deformation even to ftracture.Part water-based quenching agent by adding appropriate salt and alkali in water, like this after high temperature workpiece immerses this heat-eliminating medium, the crystal of salt and alkali can be separated out in the steam film stage and burst immediately, thus destroy steam film, the oxide skin of workpiece surface of scraping, improve the cooling power of medium in high-temperature zone, but the corrodibility of this type of quenching medium is comparatively large, and affect the clean of production environment.The developing direction of novel quenching medium mainly comprises reduction energy consumption, decreasing pollution discharge, safety and environmental protection, low-cost and high-quality etc.
