Cause analysis of slag hanging in astm a516 grade 70 maximum temperature cutting process

Our company's astm a516 grade 70 maximum temperature power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the astm a516 grade 70 maximum temperature utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

The carbon content of astm a516 grade 70 maximum temperature carbon structural steel is about 0.05% - 0.70%, some of which can be as high as 0.90%. Carbon structural steel can be divided into ordinary carbon structural steel and high-quality carbon structural steel. Carbon structural steel is mainly used in railway, bridge and all kinds of construction projects. Carbon structural steel astm a516 grade 70 maximum temperature can be used to manufacture all kinds of metal components that bear static load and unimportant mechanical parts and general weldments that do not need heat treatment.

astm a516 grade 70 maximum temperature, 30CrMnSiA steel plate is a kind of low alloy high strength steel with medium carbon, high strength and good weldability. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. After quenching and tempering, 30CrMnSiA steel can be used as grinding wheel shaft, gear and sprocket. 30CrMnSiA steel has good processability, small deformation and good fatigue resistance. 30CrMnSiA steel is usually used for shaft, piston parts, etc. It is used for various special wear-resistant parts of automobiles and airplanes.

Temperature has a great influence on the strength of the material, astm a516 grade 70 maximum temperature. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between astm a516 grade 70 maximum temperature, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.
