Background technology
To can the be magnetized content of element and detect than magnetic saturation intensity parameter following several mode is generally arranged of having in the metal material.Traditional method is that profile and all satisfactory measured material of size are tested according to the mode of doing the B-H magnetic hysteresis loop, draws the magnetic saturation intensity value, calculates the content value of magnetic element then by the method with the standard substance comparison.This kind method complicated operation, speed is extremely slow, and measuring accuracy is very low; Mode commonly used is that the hollow cavity of a rectangle is inserted in the magnetic gap, measured material by the test handle from cavity by manually sending into or pulling out and test.The relative merits of this kind mode are: simple in structure, but the volume of measured material is little, and measuring accuracy is low, and speed is slow, and data stability is poor; Having is exactly to adopt the electromagnetic type method of testing again, and test magnetic field is produced by solenoid, and sample turnover solenoid is by manually carrying out.The relative merits of this kind mode are: can carry out test automatically, but the volume of measured material is little, measuring accuracy is low, and speed is slow, and data stability is poor, and equipment volume is huge, and the electric power power consumption is big, costs an arm and a leg; Though magnetic gap and sample that external advanced detection mode is made up of the NS utmost point pass in and out system automatically, the volume of test material is little, and the volume of equipment is big, and service condition requires harsh, costs an arm and a leg, and promotes the use of seriously to be restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of metal material Armco magnetic iron, nickel, cobalt content and than the measurement mechanism of magnetic saturation intensity.Its structural design is flexible, usage range is broad, be easy to control, operate steadily, accurate positioning, easy to operate, automaticity is high, and is cheap for the measuring accuracy that improves test macro provides basic guarantee, is easy to large-scale popularization.
The purpose of this utility model is achieved like this, metal material Armco magnetic iron, nickel, cobalt content and than the measurement mechanism of magnetic saturation intensity, comprise: magnetic saturation field and magnetic induction signal supervisory instrument, magnetic gap and magnetic induction input coil that this pick-up unit is made up of the strong permanent material NS utmost point are formed; Magnetic induction input coil symmetry is fixed on the cartridge of the NS utmost point or in the magnetic gap.And, the sample transfer system, this sample transfer system is made up of position transducer, drive unit, driving shaft, sample box and sample box operation guide rail, wherein sample box is installed on the sample box operation guide rail, one links to each other with the vertical end face of guide rail and the driving shaft of drive unit, and position transducer is equipped with in the front and back end of driver.
According to the further setting to above-mentioned measurement mechanism, sample box operation guide rail passes through magnetic gap and parallel with the NS pole-face, and in suitable up and down stationkeeping.Two plane opposing parallel of NS cartridge are fixed.Anode-cathode distance between the NS utmost point is adjustable.
This measurement mechanism has overcome traditional, commonly used, electromagnetic type and the present shortcoming of advanced means abroad.Have the following advantages:
1. can be by material that changes the NS utmost point and the pole-face magnetic gap of adjusting NS, the choose reasonable drive unit can change the volume range of test parameter range and tested material, uses very flexible.
2. can reasonably design magnetic induction input coil and fit makes it reach optimum sensitivity, effectively improve measuring accuracy and resolution.
3. can conveniently change the sliding type of sample box on guide rail and carry out speed control, to satisfy the test needs of different materials.
4. can strictly control stop place and the sliding scale of sample box on guide rail, help improving the repeatability of test data.
5. because sample box move very steadily, reduced noise greatly on guide rail, very favourable to the material of testing small sample and weak magnetic.
