How to deal with iron oxide residual problem of ASTM A36 steel plates

The iron oxide residual problem is common during production of ASTM A36 steel plates. As a result, surface pock, declined qualified rate and enterprise benefits become outstand. Some methods are usually adopted to bring the loss down.

First, heating process is optimized to avoild iron oxide residual problem of ASTM A36 steel plates. The heating temperature should be uniform, and the temperature difference on 2 ends should be controlled within 20 degrees.

Second, finishing rolling enter speed is optimized to avoild iron oxide residual problem of ASTM A36 steel plates. In order to ensure the effect of the roll descaling and ensure the quality of the rolled piece, the inlet speed of the rolling mill of different sizes should be optimized.

Third, descaling process is optimized to avoild iron oxide residual problem of ASTM A36 steel plates. The number of descaling working pumps is increased to ensure the descaling pressure; double beams can be used in the descaling after the furnace and before the finishing rolling. Control rolling rhythm, avoid more than two points (including two points) descaling and the phenomenon of rolling.

Of course, there are a lot of other methods to deal with iron oxide residual problem of ASTM A36 steel plates.
