It is practical.But no matter existing or above-mentioned survey tool can only be detected to the fished pipe after cooling, be detected
It can only cut off pipe end to go out the not good pipe end of straight degree, and normally state pipe end need to cut off 100mm or so, with general state
Interior length of oil sleeve pipe 11m is calculated, and such defect excision is on lumber recovery influence=(400-100)/11000=2.7%, if with enterprise
200,000 tons of annual production, the 1500 yuan/ton of calculating of fished pipe and steel scrap head price difference, then directly cut 8,100,000 yuan/year of damage, be loss
It is huge.High-temperature steel tube is measured with existing detection instrument, existing detection instrument directly contacts heated produce with high-temperature steel tube and become
Shape, so as to influence the measurement accuracy of dial gauge, how at high operating temperatures the pipe end of measurement hot-rolled pipe is directly spent, so as to tube reducing
Machine is made optimizing and revising in time, realizes the controllability of production process, and it is existing steel pipe's production to prevent the massive losses that Pipe Cutting brings
Enterprise be eager solve technical barrier.

The lower end of gauge rod, dial gauge is vertically fixedly mounted on the center line of horizontal connecting plate by loop bar, and the round dial of dial gauge exists
The top of horizontal connecting plate, the gauge head of dial gauge fixes peace in the trapezoidal inner chamber below horizontal connecting plate in the lower end of gauge head
Equipped with heat insulation.
Further, the lower surface of the heat insulation is plane.
Further, the lower surface of the heat insulation is cambered surface.
Further, the handle is fixedly mounted on the center of horizontal connecting plate upper surface.
Further, dial gauge can horizontal sliding be arranged on horizontal connecting plate on.
This hot-rolled pipe directly spends on-line checking instrument, be provided with two medial surfaces of left vee-block and right vee-block every
Thermosphere, thermal insulation layer is contacted with hot rolling pipe surface, it is to avoid left vee-block and right vee-block temperature distortion influence measurement accuracy.In dial gauge
Gauge head lower end heat insulation is installed, prevent that dial gauge temperature distortion from damaging, this detection instrument can measure the height after tube reducing in time
Tube rolling is warmed, tube reducing unit adjustment personnel are fed back after measurement and judges rapidly and makes effective adjustment, the controllable of production process is realized
Property, the setting of handle is more convenient for the gripping of survey crew, dial gauge can horizontal sliding be arranged on horizontal connecting plate, effectively
Detect the linearity of diverse location pipe end.This hot-rolled pipe directly spends the high temperature after detection instrument can not only effectively detect tube reducing in line
Hot-rolled pipe, prevents that pipe end from bending after cooling down, and causes to cut off the massive losses that pipe end is brought, and complete without waiting for steel pipe
Cooling measurement, has been saved the substantial amounts of time, improves detection efficiency.
