Low temperature freezer

Low temperature freezer
1.1 Performance characteristics
1. It has an extremely wide temperature control range, which can meet various needs of users.
2. Adopting a unique balanced temperature regulation method, it can adjust the ideal temperature environment. It has stable and balanced heating, and can achieve high-precision and highly stable temperature control.
3. The control instrument adopts our company's independently developed color touch screen controller.
4. It has a set value that varies with temperature, and can be selected for low or high temperature, with simple operation.
5. The temperature setting inside the test box adopts a keyboard setter, making the setting simple and easy. The instrument has an error correction function when setting the temperature, and after correction, more accurate test conditions can be obtained.
6. Liquid nitrogen refrigeration is used in the refrigeration system.
1.2 Main technical parameter indicators (The following performance indicators are measured after stabilizing for 2 hours without test load)
1.2.1 Temperature performance indicators
Test purpose: Quality inspection, product development, production application, reliability testing
Technical specifications of this freezer
Temperature control range: -196 ℃~room temperature+10 ℃ (temperature range can be customized, up to 500 ℃)
Temperature fluctuation: ≤ ± 0.5 ℃
Temperature uniformity: ± 3 ℃
Cooling rate: ≥ 5-50 ℃/min (cooling rate can be customized according to customer requirements)

1.2.2 Main low-temperature freezing applications:
The hardness changes of D2 steel after quenching at different temperatures, as well as the effect of cryogenic treatment on its hardness, were analyzed, and its microstructure was also analyzed. The results showed that the hardness reached the optimal value after quenching at 1010-1040 ℃. After cryogenic treatment, residual austenite transformed into martensite, causing an increase in hardness. After cryogenic treatment, ultrafine carbides were dispersed and precipitated during tempering, and the longer the cryogenic treatment time, the more ultrafine carbides were dispersed and precipitated
The role of D2 steel freezing:
1. Improvement of wear resistance and service life of hard alloy cutting tools, cutting tools, and drill bits;
2. Improvement of wear resistance and service life of high-speed tool steel cutting tools, cutting tools, measuring tools, and drill bits;
3. Improving the performance and thermal stability of diamond drill bits, saw blades, and top hammers;
4. Improvement of dimensional stability performance of precision mechanical parts;
5. Improving the impact resistance and service life of hot and cold working molds in the mechanical manufacturing industry;
6. Improvement of wear resistance and service life of oil nozzles, springs, gears, and bearings.
