Descripción del producto

 

KHR Portable Detector for Quenching Medium Performance

â–  In line with international standards, facilitate with international advanced technology integration.

â–  Direct determination of medium cooling rate, with existing traditional indirect method than the more accurately determine the medium, the cooling performance

â–  Using portable achieved bath of dynamic measurement and control

Principle and technical parameters

KHR instrument reliable quality function is well-found, High sensitivity repeatability and reproducibility; Carrying convenient operation easy long service life. By Henan technical supervision inspection approval, is the enterprise quality guarantee system of heat treatment process monitoring the necessary tools, is to improve product quality, reduce heat and avoiding waste effective means.

Product principle

This detector according to international standards ISO9950:1995 manufacturing, adopt inside pack thermocouple nickel alloy probe testing medium performance cooling curve experimental method. Will probe heated to specified temperature (usually for 850℃), insert the waiting media cooling, through the internal microcomputer system records probe temperature on time and the cooling speed changes with temperature, and the internal four-color drawing printer will test results drawn by cooling process curve (temperature/time) and cooling characteristic curve (temperature/cold speed), Also can print the result into form output. According to the above results assess medium cooling performance.

Cooling curve method and analyzing the criterion of the principle

Criterion: maximum cold speed Vmax; Maximum speed Tvmax; where the temperature of cold 300℃ when cold speed v300; Cold to 600℃, 400℃ and 200℃ time t400 and t200 t600.

Analysis principle: Will have measured medium speed with maximum cold in advance of workpiece experimentally determine the critical speed contrast to determine the cold hardening abilities whether meet the requirements and the medium should replace or adjust; Will℃ 300 measured medium speed with cold experimental determined in advance℃ no crack safety workpiece 300 as compared to cold speed to determine media on the workpiece and medium quenching cracking tendentiousness should replace or adjust; According to the cooling curve can be determined, characteristics of medium temperature; Will the cooling curve with TTT curve and other its quench-hardening ability material together, comprehensive analysis can obtain relevant workpiece hardening of the other information.
