Abstract
The invention provides a water soluble quenching agent which is prepared by adding natrium nitrosum, sodium nitrate, alkali, soap powder and washing-powder into water. The compositions in weight percentage are 1.5 to 3 percent of natrium nitrosum, 1.5 to 3 percent of sodium nitrate, 0.8 to 2 percent of alkali, 0.8 to 2 percent of soaping powder, 0.8 to 2 percent of washing-powder, and the balancing being water. The sum of the weight percentage of the compositions is 100 percent. In the preparing process, the raw materials are put into the container according to certain percentage, and the product is prepared after the raw materials are dissolved completely and mixed sufficiently. The water soluble quenching agent has the advantages that the cooling speed is fast, the carburization and the quenching effects are good, a quenching workpeice does not have crackles, the use cost is low, and the quenching agent is applied to quenching in a carburizing quenching furnace.
Description
Affiliated technical field
The invention belongs to the metal heat treatmet quenchant, particularly a kind of water-soluble quenching agent.
Background technology
Employed quenchant is oils or water in the prior heat treatment operation at present.The low all steel that closes of carbon during oils is applicable to, the speed of cooling of oil is slow to be occurred quenching hard or problem such as the quenching hard formation is shallow easily.Water is made quenchant and is grasped water temperature is difficult, and the too high or too low hardness that all can cause of water temperature is defective, causes the quenching workpiece crack through regular meeting.Multiple water-soluble quenching medium is also arranged on the market a few days ago, but all can not satisfy the requirement that cementing furnace or quenching furnance quench.
Summary of the invention
It is fast to the purpose of this invention is to provide a kind of speed of cooling, and carburizing, quenching effect are good, and the quenching workpiece is crackle not, and use cost is low, is applicable to the water-soluble quenching agent that carburizing glowing furnace quenches.
Technical scheme of the present invention is: a kind of water-soluble quenching agent, it be in water, add inferior sodium nitrate, sell sour sodium, alkali, the clean powder of soap and washing powder are mixed formation.The weight proportion of its component is:
Inferior sodium nitrate 1.5-3% sells sour sodium 1.5-3%
The clean powder 0.8-2% of alkali 0.8-2% soap
All the other are water for washing powder 0.8-2%
Each weight percentages of components sum is 100%.
During preparation, with above-mentioned each raw material precentagewise metering and put into container, treat that each raw material dissolves fully and fully mixed back product of the present invention.
Described alkali selects for use a kind of in caustic soda, soda ash, sheet alkali or the liquid caustic soda, alkali can play neutralizing acid and lubrication protection workpiece.
Described inferior sodium nitrate and pin acid sodium mainly play antirust and quick refrigerative effect.Can prevent going up workpiece surface oxidation and decarburization.When workpiece cools off workpiece during 800-600 ℃ of temperature fast, make workpiece finish quenching, carburizing work fast and make workpiece reach required hardness.
Clean powder of described soap and washing powder can play lubrication protection workpiece and slow cooling effect, promptly can hinder work-piece cools when workpiece reaches 400 ℃ of temperature, reduce work-piece cools speed, and workpiece is not ftractureed.
The present invention can be used for the soft steel carburizing, and high, medium carbon steel quenches.Be specially adapted to processing to carbon steel, steel alloy, tool steel and die steel.
It is fast that advantage of the present invention has provided a kind of speed of cooling, and carburizing, quenching effect are good, and the quenching workpiece is crackle not, and use cost is low, is applicable to the water-soluble quenching agent that carburizing glowing furnace quenches.
Embodiment
A kind of water-soluble quenching agent, it be in water, add inferior sodium nitrate, sell sour sodium, alkali, the clean powder of soap and washing powder are mixed formation.The weight proportion of its component is:
The sour sodium 2% of inferior sodium nitrate 2% pin
The clean powder 1% of alkali 1.2% soap
Washing powder 1% water 92.8%
During preparation, with above-mentioned each raw material precentagewise metering and put into container, treat that each raw material dissolves fully and fully mixed back product of the present invention.
Claims (2)
1, a kind of water-soluble quenching agent is characterized in that: it be in water, add inferior sodium nitrate, sell sour sodium, alkali, the clean powder of soap and washing powder are mixed formation, the weight proportion of its component is:
Inferior sodium nitrate 1.5-3% sells sour sodium 1.5-3% alkali 0.8-2%
All the other are water for the clean powder 0.8-2% of soap washing powder 0.8-2%
Each weight percentages of components sum is 100%;
During preparation, with above-mentioned each raw material precentagewise metering and put into container, treat that each raw material dissolves fully and fully mixed back product of the present invention.
2, a kind of water-soluble quenching agent according to claim 1 is characterized in that: it be in water, add inferior sodium nitrate, sell sour sodium, alkali, the clean powder of soap and washing powder are mixed formation, the weight proportion of its component is:
Sour sodium 2% alkali 1.2% of inferior sodium nitrate 2% pin
Clean powder 1% washing powder of soap 1% water 92.8%
