Description
Technical field
The invention belongs to metallurgical technology field, be specifically related to a kind of low-carbon alloy steel Special quenching agent.
Background technology
The use of human civilization and metal material is inseparable.According to statistics, used by current various machinery equipments
In material, metal material still accounts for more than 90&.Quenching is the important means making metal material obtain affiliated performance, and
Hardening media is then to obtain one of high key factor of quenching quality.Before 20th century, substantially use dynamic planting
Thing grease carries out quenching.Vegetable and animals oils contains more unrighted acid, because of hydrolysis, oxidation etc. can produce carboxylic acid,
The material of the smell with irritating such as aldehyde, ketone, it is easy to become sour rotten, produces ill effect to environment.Simultaneously as
The instability of component, quenches of low quality, and such people have to separately find new hardening media.
Flourish along with petroleum industry.In 20 beginnings of the century, mineral oil starts to be used for quenching cooling.Mineral oil
Main component is saturated hydrocarbons, and performance is the most stable, so being widely used.For improving the cooling performance of mineral oil,
People develop again and to the quenching oil containing various additives that mineral oil is base, remain the hardening media of main use.
But, environment is caused severe contamination by mineral oil quenching medium, and mineral oil flash is relatively low, in quenching process, is formed dense
Cigarette fire-prone, aggravate the most significantly containing this danger during water in oil.The degradability of mineral oil is very poor, institute
The biggest to the potential threat of the pollution of environment with discarded mineral oil.Investigation finds, the mineral oil of waste emission is underground
The primary pollution source of water.For improving quenching oil performance, add many surfactant-based additives.Great majority add
Agent all increases the difficulty of liquid waste processing, such as the additive such as compound of baric, or potential carcinogen, further
Increase the environmental hazard of mineral oil quenching medium.Existing increasing enterprise abandons when being heat-treated using oil quenching in recent years
Fire, and the cooling medium using various water soluble polymer organic aqueous solution to be steel alloy quenching.But, this kind of water-soluble
Although property organic cooling medium is used for when quenching not producing severe contamination and there is not disaster hidden-trouble, but market price is still
The highest, and, the former media storage phase is limited, and user the most separately needs to be configured to the aqueous solution the most by a certain percentage just after buying
Can use, in use, organic solution after heated can accelerated ageing so that it is cooling characteristics changes, as not in time
Change, Ways of Heat Treatment Product Quality will be made to decline, the most qualified.
