Liu Huanan

Graduated from the metallurgy major of Northeast University in 1962, researcher and doctoral tutor.He has been engaged in the research of corrosion-resistant materials in the Institute of Metal Protection And Corrosion, Chinese Academy of Sciences for more than 30 years, and is now the director researcher of the National Metal Corrosion Control Engineering Technology Research Center.The XD-1 corrosion-resistant and high temperature resistant material developed by Liu Huanan won the Sun Shibo award.F518, F7, FS-1 and other sulfuric acid materials won the second prize of major scientific research achievements of Chinese Academy of Sciences.His research on corrosion-resistant materials in fan, water pump and valve industry has won many major scientific research achievement awards.The materials of special three eccentric butterfly valves for 610 ℃, 450 ℃, SO2 and SO3 developed for XDV Group are listed in the new product development plan of Zhejiang Province in 1997.Pass the provincial appraisal in 1998, the two products filled the domestic gap and reached the domestic leading level.

ZG-3 Vacuum Medium Frequency Induction Furnace

The ZG-3 furnace is a periodic operation electric furnace, the amount of molten steel is 3kg. The power supply is 30kW,and the medium frequency is 8000Hz. It is mainly used for melting and ingot casting of special steels and super alloys in vacuum or protective atmosphere. It is also used for heat treatment such as quenching and annealing of small parts.

600MRD-S Digital Display Surface Rockwell Hardness Tester

The surface hardness tester adopts ROCKWELL measurement principle,the surface Rockwell hardness can be measured directly.With wide measuring range.It can measure the hardness of 15 scales such as HR15N、HR30N、HR 45N、HR15T、HR30T.And the surface Rockwell hardness value can be converted to HRC、HRB、HB、HV、HLD、HK value.It is mainly used for hardness testing of carbon steel, alloy steel, cast iron, non-ferrous metals and engineering plastics.

JB-300B Impact testing machine

The maximum impact energy is 300 joule, with a 150 joule pendulum, and the cross-section of the sample used is 10×10 mm2.It is mainly used to determine the impact resistance of steel and its alloy materials under dynamic load, so as to judge the properties of materials under dynamic load.

Direct Reading Spectrometer

Arll3460 direct reading spectrometer is produced by Thermo Fisher Technology Co., Ltd. It has 35 optical channels and can detect 26 elements, including the main elements of all metals, such as carbon, phosphorus, silicon, sulfur, nickel, chromium, copper, moscovium, aluminum, nitrogen, manganese, etc. It is applicable to the analysis of nodular cast iron, gray iron, cast steel, cast aluminum and other metal materials and special cast iron materials. At present, it is widely used for bath analysis and laboratory analysis in machinery, nonferrous steel and other industries.

M-2000 Abrasion tester

Purpose:It can test the wear resistance of materials under various conditions of sliding friction, rolling friction, rolling, sliding compound friction and intermittent contact friction.

WEW series screen display hydraulic universal testing machine

Purpose:

The testing machine is widely used for tensile, compression, bending and shear tests of metal materials, and meets the requirements of GB / T228-2002 Tensile Test Method For Metal Materials At Room Temperature. It can also be used for the compression test of non-metallic materials such as cement and concrete. After adding special accessories, the mechanical properties of fasteners, steel wire ropes and components can be tested. It is an ideal testing instrument for quality inspection departments, engineering quality testing units, colleges and universities and large industrial and mining enterprises.

Performance characteristics:

1. The main machine structure reference foreign technical design, the machine structure is compact, reasonable layout, compared with the upper type in the test space under the premise of the same greatly reduce the height of the machine. Indirect force measurement using hydraulic sensor, compared with load sensor has the advantages of strong impact resistance, long service life. The worm wheel and worm transmission mechanism across the moving beam is used to adjust the test space. Compared with the chain transmission mode, it does not need the characteristics of screw rotation when adjusting the test space, so that the transmission system and the positioning system are completely separated, ensuring the coaxiality of the upper and lower jaws and the durability of the host. The unique lead screw clearance elimination mechanism ensures the continuity of test loading.

2. Independent hydraulic clamping mechanism to ensure the reliability of the clamping system, the sample will not fall off and hurt people, to ensure the safety of the test personnel.

3. With mechanical limit and electrical protection double protection device to ensure the safety of use.

4. test data using Access database management, powerful, easy to operate.

5. Reserve data interfaces for directly connecting to the network for resource sharing.
