Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter SPA-H SPA-C weather resistant steel steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.
According to SPA-H SPA-C weather resistant steel traders in some regions, the downstream purchasing sentiment is maintained, the inventory resources are relatively small, and the SPA-H SPA-C weather resistant steel traders are more willing to strike a deal; in addition, the domestic steel mills have issued guidance prices recently, and the long-term upward range is large, which has a boosting effect on the market. In addition, there are SPA-H SPA-C weather resistant steel production line maintenance at the end of the month, so the supply side is tight. Overall, the short-term forecast for SPA-H SPA-C weather resistant steel will fluctuate mainly upwards tomorrow.
The fake and inferior SPA-H SPA-C weather resistant steel, steel plates have no metallic luster and are light red or similar to pig iron for two reasons. 1. Its blank is adobe. 2. The rolling temperature of counterfeit and inferior materials is not standard, and their steel temperature is visually inspected. In this way, rolling cannot be carried out in the specified austenite area, and the performance of the steel plate will naturally not meet the standard.
CortenB vs 45#: Corten B medium-carbon quenched and tempered steel has higher strength, toughness and hardenability than 45# steel. Corten B steel can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance is still good, but the welding performance is poor, the cold deformation plasticity is low, and the temper brittleness tendency. It is generally used in quenched and tempered state, and can also be used in quenched, tempered or normalized state.
