Problems solved by technology

The disadvantages are: first, the size error of the blank is large; second, when the free forging billet is made, a natural gas furnace is generally used for heating, and the heating temperature cannot be accurately controlled; third, there is no protective layer on the surface during the heating process, and surface oxidation is easy to occur Phenomenon, and thick oxide skin will also be produced in the forging process, which not only increases the consumption of raw materials, but also cannot guarantee the surface quality of the obtained blank
