Description
Technical field
The present invention relates to heat-treatment quenching technical field, refer more particularly to a kind of medium carbon alloy steel high-abrasive material quenching medium.
Background technology
The use of human civilization and metallic substance is inseparable.According to statistics, in material used in current various machinery equipment, metallic substance still accounts for 90 more than &.Quenching is the important means making metallic substance obtain affiliated performance, and quenchant is then one of key factor obtaining high quenching quality.Before 20th century, animal-plant oil is substantially adopted to quench.Vegetable and animals oils contains more unsaturated fatty acids, can produce the material of the smells with irritating such as carboxylic acid, aldehyde, ketone because of hydrolysis, oxidation etc., is easy to become sour rotten, produces ill effect to environment.Meanwhile, due to the instability of component, quench of low quality, such people have to separately find new quenchant.
Flourish along with petroleum industry.In 20 beginnings of the century, mineral oil starts to be used to quench cooled.Mineral main body of oil is stable hydrocarbon, and performance is relatively stable, so be widely used.For improving the cooling performance of mineral oil, people develop again and to mineral oil be base containing the quenching oil of various additive, remain the main quenchant used.But mineral oil quenching medium causes severe contamination to environment, mineral oil flash is lower, in quenching process, forms dense smoke and fire-prone, greatly aggravates especially in oil containing this danger during water.The degradation property of mineral oil is very poor, so discarded mineral oil is just very large to the potential threat of the pollution of environment.Investigation finds, the mineral oil of waste emission is the primary pollution source of underground water.For improving quenching oil performance, add many surfactant-based additives.Most of additive all increases the difficulty of liquid waste disposal, as the additive such as compound of baric, or potential carcinogenic substance, increase the environmental hazard of mineral oil quenching medium further.Existing increasing enterprise abandons when thermal treatment using oil quenching in recent years, and adopts various water-soluble polymer organic aqueous solution to be the heat-eliminating medium that steel alloy quenches.But, although this kind of water-soluble organic cooling medium is used for not producing severe contamination and there is not disaster hidden-trouble when quenching, but market price is still very high, and, the former media storage phase is limited, also separately need to be mixed with the aqueous solution voluntarily by a certain percentage after user buys could use, in use, organic solution after heated can accelerated deterioration, its cooling characteristic is changed, as changed not in time, Ways of Heat Treatment Product Quality will be made to decline, even unqualified.
