(2) Control the thermal correction of steel and steel components. The heating temperature shall not exceed 9000C (the thermal correction workers control the temperature by the color of the heating zone). It is strictly forbidden to force cooling of low-alloy steel (such as watering). Use a vernier caliper or aperture gauge to randomly check 10% of the bolt hole diameters and hole wall quality, and randomly check the bolt hole spacing. (3) If the self-inspection of the steel structure contractor is qualified and the random inspection of the supervisor is qualified, the steel parts and steel component processing project is qualified.
