Abstract
The invention relates to the technical field of heat treatment quenching, and discloses a quenchant for medium carbon alloy steel abrasion-resistant material. The quenchant comprises, by weight, 6% to 8% of sodium hydroxide, 6% to 8% of zinc chloride, 1% to 5% of sodium chloride, 0.01% to 0.03% of sulfonated castor oil, 0.01% to 0.05% of antifoaming agents, 0.1% to 0.5% of soap, 0.1% to 0.4% of preservative, 0.1% to 0.5% of antirust agents, 0.1% to 0.5% of lubricants, 0.1% to 0.5% of sterilizing agents and the balance water. The quenchant is reasonable in formula, and a quenched piece can have high hardness and is even in hardness. Sodium hydroxide and oxide skin on the surface of the quenched piece can interact with each other to generate hydrogen, so that the oxide skin can be rapidly peeled off, and the surface of the quenched piece can be in a shining silver color. Zinc chloride and sodium hydroxide react to generate strong zinc oxide, and the cooling speed of a high temperature area is higher than the cooling speed of water while the cooling speed of a low temperature area is lower than the cooling speed of water, so that deformation of the quenched piece is small, the quenched piece is not prone to cracking, and the surface of the quenched piece is shining.
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 current various machinery equipment in material used, more than metallic substance still accounts for 90 &.Quenching is to make metallic substance obtain an important means of affiliated performance, and quenchant is one of key factor obtaining high quenching quality.Before 20th century, substantially adopt animal-plant oil to quench.Vegetable and animals oils contains more unsaturated fatty acids, because of the material of the smells with irritating such as meeting generation carboxylic acid, aldehyde, ketone such as hydrolysis, oxidation, is easy to become sour rotten, and environment is produced to ill effect.Meanwhile, unstable due to component, quenches of low quality, like this people's another new quenchant of finding of having to.
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 the quenching oil that contains various additives that is base to mineral oil, remain the quenchant of main use.But mineral oil quenching medium causes severe contamination to environment, mineral oil flash is lower, in quenching process, forms dense smoke fire-prone, this danger aggravation greatly especially contain water in oil time.The degradation property of mineral oil is very poor, so the potential threat of the pollution of discarded mineral oil to environment is just very large.Investigation discovery, the mineral oil of discarded discharge is the primary pollution source of underground water.For improving quenching oil performance, many surfactant-based additives are added.Most of additives have all strengthened the difficulty of liquid waste disposal, as additives such as the compounds of baric, or potential carcinogenic substance, the environmental hazard that has further strengthened mineral oil quenching medium.Existing increasing enterprise abandons using oil quenching in the time of thermal treatment in recent years, is the heat-eliminating medium that steel alloy quenches and adopt various water-soluble polymer organic aqueous solutions.But, although the water-soluble organic cooling medium of this class does not produce severe contamination and does not have disaster hidden-trouble while being used for quenching, but market price is still very high, and, the former media storage phase is limited, after user buys, also separately needing to be mixed with by a certain percentage voluntarily the aqueous solution could use, and in use, organic solution after heated can accelerated deterioration, its cooling characteristic is changed, as changed not in time, will make Ways of Heat Treatment Product Quality decline, even unqualified.
