Abstract
The invention provides a water-soluble quenching agent which comprises the following components in percentage by mass: 5-8% of sodium chloride, 15-18% of industrial sodium silicate, 6-8% of potassium nitrate, 1-2% of starch and the balance of water. The invention also provides an application of the water-soluble quenching agent in low-carbon steel quenching. The water-soluble quenching agent provided by the invention can meet and control the hardenability of a material so as to avoid cracking of the material.
Description
Technical field
The present invention relates to a kind of water-soluble quenching agent.
Background technology
In the treatment production process, often find that the part steel grade is as used oil cooling, its hardening capacity is poor, and quenching hardness is lower, and grain fineness number checks substandard requirement.And the raising of quality product and thermal treatment quality have close relationship, because oily speed of cooling is slow, be difficult to meet pure requirement thoroughly.And adopt water cooling speed fast, the easy through hardening of workpiece but easily crack.
The material of same batch is carried out to equal thermal treatment by normal heat treating method, adopt respectively again the cooling of water and two kinds of quenchants of oil, process is to metallographic structure, grain size number, surface hardness, the contrast of the multinomial test such as core hardness and tensile strength, impelling strength, can find out, adopt the material core of oily medium quenching obviously to produce needle-like and granular ferrite; And obvious needle-like and granular ferrite do not appear in the material core that adopts aqueous medium to quench, the tempering troostite that the metallographic of oil quenching material is 60%, and the metallographic of shrend material is the tempering troostite more than 75%, after simultaneous test, water quenching obviously is better than oil quenching, but also defectiveness, can not control and reach desirable requirement.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of water-soluble quenching agent, the hardening capacity that can meet material can be controlled the hardening capacity of material again and material is not cracked.
The invention provides a kind of water-soluble quenching agent, comprise each component of following mass percent: sodium-chlor 5-8%, industrial metasilicate 15-18%, saltpetre 6-8%, starch 1-2%, all the other are water.
Preferably, described water-soluble quenching agent comprises each component of following mass percent: sodium-chlor 6%, and industrial metasilicate 16%, saltpetre 7%, starch 1%, all the other are water.
The present invention also provides the above-mentioned application of water-soluble quenching agent in soft steel quenches.
Preferably, be to immerse in water-soluble quenching agent of the present invention and quenched after soft steel is heated to 700-750 ℃, the cool time is 5-10s.
Further, the described cool time is 7s.
Preferably, the temperature of described water-soluble quenching agent is 25-40 ℃.
Further, the temperature of described water-soluble quenching agent is 30 ℃.
