The article is to investigate the effect of quenchant parameters of concentration, fluid velocity (agitation intensity), temperature for PVP type SQ1501 aqueous polymer quenchant on quenching characteristics of steel by a series of experiments. Quenching experiments of some kinds selected steel alloy materials (JIS-SKT4, B30PH, 4M, AISI-4140M and JIS-SCM440) specimens were conducted at laboratory; a series of pilot tests of steel products at the heat treatment factory also were carried out to demonstrate the experimental results. The experimental results show that the full hardness of the above mentioned quenched steel alloy materials JIS-SKT4, B30PH, 4M and AISI-4140M were decreased as concentration of polymer quenchant is increased from14.3% to 20% with fluid velocity 0.05~0.1m/s at room temperature, the hardness of the low hardenability alloy steel was affected significantly by concentration increasing. It will induce quenching crack of high hardenability alloy steel JIS-SKT4 and AISI-4140M as concentration of polymer quenchant was decreased to 9.1%;the surface hardness of low hardenability alloy steel JIS-SCM440 will be increased to HRC52~55 as concentration of polymer quenchant was decreased to 5.9%.The influence of fluid velocity (agitation intensity) on hardening depth of high hardenability alloy steels(JIS-SKT4、B30PH and AISI-4140M) is insignificant compared to the low hardenability alloy steel JIS-SCM440. While temperature of polymer quenchant was increased from 26℃ to 50℃with polymer concentration of 14.3% at 0.05~0.1m/s fluid velocity, the hardness of three kinds alloy steels(JIS-SKT4, B30PH and AISI-4140M) were decreased about HRC2~3; but 4M was decreased significantly about HRC9~10. According to the experiment results from laboratory, the optimum parameter of PVP type SQ1501 aqueous polymer quenchant is 14.3% concentration, middle agitation intensity (fluid velocity is about 0.05 ~0.1m/s); and quenchant temperature is at room temperature. The above selected steel alloy materials JIS-SKT4, B30PH, 4M and AISI-4140M will obtain good harden uniformity as they were quenched in PVP type SQ1501 aqueous polymer quenchant under this optimum parameter. But the hardness of low hardenability alloy bar steel JIS-SCM440 can not fit the hardness demand;it is founded that the trapped air will affect cooling rate of polymer quenchant at boiling stage during experiment process, it will cause seriously the hardness drop;thus it is necessary to avoid air entrapping during cycling agitation. Using the experiment results, we carried out a series of pilot tests of steel products at heat treatment factory. The results show the surface hardness of different thickness bulk steel materials for B30PH which were quenched and tempered is lower than the hardness specification demand; however, the hardness difference of cross-section can fit the demand (hardness difference < HRC4). Therefore the surface hardness and hardness difference of cross-section will fit the demand provided that the full hardness of quenched material is increased about HRC2 and then through tempering treatment, or to decrease the tempering temperature. The hardness of the other bulk steel materials JIS-SKT4, B30PH and AISI-4140M can not completely fit the hardness demand of specification. The product pilot tests show that the hardness of JIS-SCM440 steel plate materials with 45, 50mm thickness and JIS-SCM440、SNCM439 circular bar steel materials with different diameters can fit the hardness demand of specification (HRC 28~32); but the hardness of JIS-S50C bar steel in product pilot test is too low (HRC18~21) to fit the hardness demand of specification(HRC22~25), therefore it is necessary to decrease the tempering temperature to 450 ℃for this carbon steel. The result hardness difference for JIS-SCM440 circular bar steel material between experiment at laboratory (1st generation quenching equipment) and pilot test at the heat treatment factory can be improved by the modification on agitation system of quenching equipment (2nd generation quenching equipment); after increasing fluid velocity (agitation intensity) in the 2nd generation quenching equipment, it is to demonstrate again the hardness result fit expectable demand.

The purpose of this article is to investigate the effect of PVP type polymer quenchant parameters including concentration, fluid agitation velocity, temperature, and nano-particle additives on quenching characteristics for several selected steels. By changing the parameters of PVP polymer quenchant and adding montmorillonite nano-particle additives, we reveal the effect of these parameters on the hardness distribution, hardening depth, quenching distortion and microstructures for several selected steels, and also look for the optimum quenchant parameters to reduce the quenching distortion based on hardenable condition. Finally, a comparison was conducted on the quenching characteristics and the improvement condition of quenching distortion between polymer quenchant quenching and conventional oil (temperature at 70 ° C) quenching in order to estimate the feasibility of PVP polymer quenching media to replace conventional mineral oil on quenching application for steels. The experimental results show that quenched hardness of all selected steels in this study is decreased as the polymer concentration of quenchant is increased from 10% to 30% with fixed fluid agitation velocity at room temperature (26°C). Hardness decline of JIS-SNCM439 and JIS-SKD61 steels with high hardenability is not large; hardness downward tendency of middle hardenability steel JIS-SCM440 is obvious; and hardness of lower hardenability steel JIS-S45C will be significantly reduced, too. The hardness of all selected steels will increase as fluid agitation velocity of quenchant increases at room temperature (26°C); hardness increment margin is low for high hardenability steels JIS-SNCM439 and JIS-SKD61, and hardening depth of middle hardenability steel JIS-SCM440 and lower hardenability steel JIS-S45C can be significantly enhanced as fluid agitation velocity is increased. Hardness of quenched specimen will be reduced as quenchant temperature was raised from room temperature (26° C) to 40°C; the lower is the steel hardenability, the higher will be the effect result. Hardness of quenched specimens for high hardenability steels JIS-SNCM439 and JIS-SKD61 will decrease slightly as PVP polymer quenchant was added the additives of montmorillonite nano-particle; it is quite obvious that montmorillonite nano-particle has a barrier effect of heat transfer. When polymer concentration is increased from 10% to 30% and fluid agitation velocity of quenchant is constant at room temperature (26 ° C), the maximum deflections of unit length of high hardenability steels JIS-SNCM439, JIS-SKD61 and middle hardenability steel JIS-SCM440 will reduce; but the effect is not obvious significantly as polymer concentration exceeds about 20%. Maximum deflection of unit length for lower hardenability steel JIS-S45C will decrease as the polymer concentration is increased from 10% to 20%; but cross-section hardness of specimen cannot achieve hardening standards as the concentration is increased to 20%. Proper fluid agitation velocity can reduce quenching distortion of specimen; maximum deflection of unit length for specimen can be reduced to minimum as fluid agitation velocity is at 0.3m/sec for above-mentioned several selected steels. When quenchant temperature was raised from room temperature (26°C) to 40°C, maximum deflection of unit length for specimen will be decreased. Maximum deflection of unit length for high hardenability steels JIS-SNCM439 and JIS-SKD61 can be effectively reduced as montmorillonite nano-particle was added to PVP type polymer quenchant. The selected steels were quenched by using optimum polymer quenchant parameter and conventional oil quenchant parameter in this study, quenched steels will obtain approximate hardness. PVP type polymer quenchant is applicable to quenching hardening for JIS-SNCM439 and JIS-SKD61, but is not applicable for quenching of JIS-SCM440 and JIS-S45C. In this study, quenchant parameters of reducing quenching distortion for JIS-SNCM439 and JIS-SKD61, JIS-SCM440, JIS-S45C is respectively polymer concentration at 20% (and adding 4% montmorillonite nano- particle), 20%, 15% with fluid agitation velocity 0.3m/sec at room temperature (26 ° C).
