classification The hot-rolled ribbed steel bar is divided into three grades: HRB335 (the old grade is 20MnSi), grade three HRB400 (the old grade is 20MnSiV, 20MnSiNb, 20Mnti), and grade four HRB500. There are two commonly used classification methods for reinforcing bars: one is to classify according to geometric shape, and the other is to classify or classify according to the cross-sectional shape of transverse bars and the spacing of bars. Type II.This classification mainly reflects the...
Cathode copper generally refers to electrolytic copper The blister copper (containing 99% copper) is pre-made into a thick plate as the anode, the pure copper is made into a thin sheet as the cathode, and the mixed solution of sulfuric acid and copper sulfate is used as the electrolyte. After electrification, copper dissolves from the anode into copper ions (Cu) and moves to the cathode. After reaching the cathode, electrons are obtained and pure copper (also known as electrolytic copper...
description H-beam is an economical section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross section is the same as the English letter “H”. Since all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used. introduce The se...
