Reasons and countermeasures for failure of tensile fracture of Q690C carbon steel plate sheet

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while Q690C carbon steel plate sheet steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of Q690C carbon steel plate sheet steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

S420M and S420ML are hot-rolled flat weldable fine-grained structural steel with a thickness less than 120mm. Q690C carbon steel plate sheet, S420 steel is a non-alloy structural steel. The S420ML steel is composed of the following parts: S (structural steel); 420: the yield strength value of structural steel with a thickness less than 16mm: not less than 420; M represents his delivery status, that is, hot mechanical rolling; L: The impact when the temperature is not lower than -50 degrees is marked with a capital letter L.
