Superior process production line advantage sdf: The company has focused on weathering steel raex 500 sheet material, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.

For the estimation in April and the second quarter, the estimation on March 16 is still valid, but the decrease in April is 10% higher than the neutral prediction. It is a conservative estimation based on 10% for the high probability event. In the second quarter, the output of overseas pig iron will be reduced by 11.67 million tons, affecting the demand for raex 500 sheet material iron ore of about 1.84 million tons; in the first half of the year, the output will be reduced by 18.899 million tons, affecting the demand for iron ore of 32.13 million tons.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for raex 500 sheet material and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

The thermal conductivity of NM360 wear-resistant plates is only 1/2 of that of carbon steel, raex 500 sheet material, and even in the high temperature stage of 900-1000℃, the thermal conductivity is lower than that of carbon steel at the same temperature. Therefore, the heating rate of the NM360 wear-resistant plate, especially in the low temperature stage, should be lower than that of carbon steel to avoid excessively steep internal temperature gradients and cracks.
