High Temperature Rockwell Test System HRN/T150

 

 

1. meet the standard: Hrn / t150 can be used to measure the Rockwell and surface Rockwell hardness from room temperature to high temperature. It is most suitable for testing the high temperature hardness of heat-resistant metal materials, ceramic products and other new materials. For superficial and standard Rockwell hardness tests: a. ISO 6508-1, Metallic materials – Rockwell hardness test – Part 1: Test method (scales A-B-C-D-E-F-G-H-K-N-T) b. ISO 6508-2, Metallic materials – Rockwell hardness test – Part 2: Verification and calibration of testing machines (scales A-B-C-D-E-F-G-H-K-N-T) c. ISO 6508-3, Metallic materials – Rockwell hardness test – Part 3: Calibration of reference blocks (scales A-B-C-D-E-F-G-H-K-N-T)

2、 Product introduction: High temperature hardness is undoubtedly unique and unique in many material performance tests. In the field of dynamic mechanics, materials are heated up instantaneously under high strain conditions, resulting in instantaneous changes in strength and hardness. Therefore, the relationship between temperature and hardness is the key index to study material damage and failure. High temperature hardness test system is a very necessary equipment for dynamic mechanics research 。 Because hardness test is a destructive test, the hardness of materials will change at any time under different temperatures, and a single test method can not get the exact hardness value of the same sample under different conditions, so we need to measure the hardness of materials under different conditions in different ways, which is the existence power of our high temperature hardness. High temperature hardness test is to measure the hardness of materials at a higher temperature. High temperature hardness is very necessary in many cases, such as tool steel materials, wear-resistant coating, such as valve seat and application mold, which are all used at high temperature. High temperature hardness can identify different properties of various materials at high temperature, which has great practicability. It can not be used to evaluate the high temperature performance because the change of indoor temperature is not related to the change of hardness. However, the hardness of materials changes greatly when the temperature changes significantly, such as tempering, wear, corrosion and thermal erosion. Therefore, the problems of pressure and high temperature creep fracture performance, aging, sliding wear, softening, creep deformation and other problems are to be solved by studying the high temperature hardness of materials. In general, materials become soft under high temperature, which may lead to wear. This kind of adhesive wear and material damage between metal surfaces are common causes of failure of parts or equipment in industry, which can not be studied carefully. The instrument can measure the Rockwell hardness from normal temperature to high temperature, which is most suitable for testing the high temperature hardness of new materials such as heat-resistant metal materials and ceramic products. It includes the following key components: Hardness tester host: digital display double Rockwell hardness tester, equipped with special probe, directly test Rockwell and surface Rockwell of sample in high temperature environment. The shaft part of the high temperature furnace keeps the sealing in the furnace and makes the furnace rise and fall freely. The Rockwell probe can apply the test force from the furnace to the sample in the furnace. Moreover, the control of the test force and the test force applied from outside the furnace depends on the external Rockwell hardness tester host. High temperature furnace: the high temperature furnace is connected with the shaft and can move up and down the heating device. It is a sealed heating chamber with sample heating device and sample moving device. There are sample placing platform, heating wire, heat preservation furnace and inert gas protection device. Heating environment control system: first, heat the high temperature furnace to the required temperature, and then measure the hardness of the sample. During the test, the sample is placed in the high temperature furnace to maintain the high temperature state. The temperature control system can realize the arbitrary rise and fall of temperature and maintain the temperature. The inert gas protects the sample from oxidation. The special probe of high temperature hardness tester is used to apply the Rockwell hardness pressure from outside the furnace to complete the automatic Rockwell hardness test. Water cooling system: in order to protect the operator's safety, the well sealed furnace body is filled with constant temperature circulating water to keep the surface of the high temperature furnace at constant low temperature. 3、 Rockwell hardness tester function: Hrn / t150 adopts the advanced micro electric programmable control technology to control the hardness test from the whole process, in which the hardness measurement is completely completed by the hardness tester, no one is responsible for the operation and human error. LCD digital display screen is the central control interface of the machine, through which the setting and operation of parameter setting, programming, data display, data statistics and storage can be completed, which increases the automation of man-machine dialogue and improves the working efficiency. The equipment loading system adopts closed weight frame and humanized push rod to realize the process of test force selection and automatic loading and unloading. It can eliminate the instability of weight frame caused by traditional knob force selection. The stability of the loading system is one of the important factors for the stability of the machine.

4、 High temperature furnace and temperature control system: The high temperature furnace adopts the most advanced all fiber vacuum pressing furnace in the world, which has the characteristics of energy saving, beauty, long service life and convenient installation and maintenance; the temperature control system adopts artificial intelligence control, which has the advantages of high temperature control accuracy, stable and reliable performance. The furnace body and furnace cover adopt the solid structure of double-layer stainless steel, hollow and flowing water, good cooling effect, constant temperature of shell temperature 25 ° C, to protect the operator's safety. The high temperature furnace adopts high-performance built-in heating body, with fast temperature rising speed, sensitive regulation, high precision, stable temperature, large expansion of temperature working line, PID temperature controller, reliable performance and convenient use. The temperature can be adjusted by programming. The center of the high temperature furnace is rigidly connected with the spindle of the hardness tester, the furnace is inlaid with heating furnace wires, and the furnace center is equipped with a high temperature resistant horizontal stage with a diameter of 40mm, which can be placed with samples of the same size as the stage for high temperature hardness test.
