We produce hexagonal steel bar by cold drawing through hex mould from hot rolled steel round bar. In this way, hexagonal steel bar has precision size tolerance, better surface and sharp corner radius. Except cold drawn hexagonal steel bar, we can also produce heat treated hexagonal steel bar. For example, annealed hexagonal steel bar, qhenched and tempered Q&T hexagonal steel bar. After heat treatment, hexagonal steel bar mechanical properties will be better or higher. For heat treated hexagonal steel bar, straightness is very important. We have fine straightening machine to do straightening to keep good straightness.

When adjusting an integral temperature transmitter, note the following four points:
1, pay attention to the polarity when wiring, and start the adjustment after the power is warmed up for 15 minutes. ,
2. The signal is input at a slow speed in the adjustment to ensure that no overshoot occurs.
3. Do not use excessive force when adjusting the potentiometer to prevent it from being damaged.
4. Before calibration, prepare a calibration record sheet and check the thermocouple temperature/millivolt reference table or thermal resistance temperature/resistance comparison table at each calibration point, and identify and fill in the required data. Good data record table.
