为解决冷轧冷拔高压锅炉钢管在运输和贮存中的锈蚀与散捆问题,首钢特殊钢公司设计制造了一条钢管防锈和机械打捆作业线,并已投入生产。该线用于成品钢管的防锈和打捆。防锈采用静电喷涂工艺。通过在密闭的静电喷涂室内喷涂一种硬膜防锈油,使钢管表面在短时间内(不超过3 min)形成一层干燥的透明防锈膜。该膜不影响随后在管面上印字,使用前也无须除去,并且防锈的效果比目前
In order to solve the problem of rust and loose bales in the transportation and storage of cold-drawn cold-drawn high-pressure boiler tubes, Shougang Special Steel Co., Ltd. designed and manufactured a steel pipe rust-proofing and mechanical baling operation line which has been put into production. This line is used for rust prevention and baling of finished steel pipe. Rust using electrostatic spraying process. A dry, clear anti-rust coating is formed on the surface of the steel pipe in a short period of time (less than 3 min) by spraying a hard coat anti-rust oil in a closed electrostatic spray booth. The film does not affect the subsequent printing on the tube surface, there is no need to remove before use, and the effect of rust than the current
