Besides the steel pipes and steel structures, we are able to provide the casting pieces or Aluminum Casting in dredging and marine area.
Pattern will be made first and done inspected before casting.
Cast pieces are presented in the foundry, for inspection of dimensions and hardness after sandblasting and machining but before conservation and painting. Deviations are sanctioned as follows for example:
GS30Mn5
surface + volume
DIN1690 class 4
DIN1690 class 4
shrinkage
DIN1690 class 5
DIN1690 class 4

Pattern and Casting
When using the caving method to return to the mining column, the ore-extracting conditions are worse than those in the mine. Because when the ore body inclination angle is 55 ~ 70 °, the empty field method is used to return to the mining room, the ore can be released smoothly by its own weight, and when it is returned to the mining column by the caving method, the ore body is discharged under the condition of covering the upper part of the rock. Dip angle, the effect of mining is quite different. Many of the ore remains in the lower plate and cannot be lost. In this case, the throwing ore mining method cannot be used to improve the ore loss index.
