For different shape of steel proucts, the dimensions and surface quality of steel products can be detected with different devices.
Round shape section
Steel with round cross-section, including high wire, steel wire, steel pipe, round steel, round bar and other steel, the detection of outer diameter and ellipticity adopts the calibrator, no matter it is a wire or a large-diameter steel pipe, there are corresponding calibrators for detection, the detection of straightness adopts straightness measuring instrument, and the detection of surface defects adopts profilometer.
Polygon shape section
Angle steel, square steel, hexagonal steel, octagonal steel, etc., the same application of the detection of diameter measurement instrument for detection, according to the number of different edges and angles, the use of different groups of diameter measurement instrument for the detection of the edge length or diagonal, the surface defects using the profiler for measurement.
Plate type
Medium-thick plate, container plate, medium plate carbon plate, boiler plate, low alloy plate, pattern plate, cold plate, hot plate, cold rolled plate, hot rolled plate, galvanized plate, electric galvanized plate, electric galvanized coil, manganese plate, stainless steel plate, silicon steel sheet, colour coated plate, colour steel tile corrugated iron, galvanized coil, hot rolled strip and other plates are used to detect the width of photoelectricity,laser thickness gauge for thickness detection, which the thin type of sheet metal using ray thickness gauge for accurate detection, the length gauge for detecting length.
Ribbed steel bars
Rebar and anchor steel have special caliper for measuring , and eight-axis sizing instruments can also be used to detect the size of rebar, and the surface defects are detected with the profilometers
Others
The surface quality and the geometric dimensions of H-shaped, triangular, groove and other complex cross-section rolled products can be detected with the contour meter.
