Ordinary mechanical spring doesn’t have good linearity since it tends to be under the influence of the end ring effect, so the linear spring with rectangular cross-section is usually chosen which advantages are as follows: Firstly, it can use materials with larger cross-section than the round one to store more energy when its spiral outer diameter is under the space limitation.

Spherical steel slag filter material with high porosity, large specific surface area was made by using steel slag as the main raw material, adding binder and pore forming agent.
The test materials and methods Test materials Steel slag in the experiment was taken from some steel mills in Shandong.
Large concentrations difference of phosphorus between the surface of filter material and the solution is advantageous to the phosphorus migration to the surface of the filter material.
