Magnetic　Barkhausen　noise　(MBN)　signals　in　the　stage　from　saturation　to　remanence　of　the　hysteresis　loop　are　closely　correlated　with　magnetocrystalline　anisotropy　energy.　MBN　events　in　this　stage　are　related　to　the　nucleation　and　growth　of　reverse　domains,　and　mainly　affected　by　the　crystallographic　textures　of　materials.　This　paper　aims　to　explore　the　angle-dependent　magnetocrystalline　anisotropy　energy.　Based　on　the　consideration　of　macroscopic　magnetic　anisotropy,　with　the　concept　of　coordinate　transformation,　a　model　was　firstly　established　to　simulate　the　magnetocrystalline　anisotropy　energy　(MCE)　of　a　given　material.　Secondly,　the　MBN　signals　in　different　directions　were　tested　with　a　constructed　experimental　system　and　the　characteristic　parameters　extracted　from　the　corresponding　stage　were　used　to　evaluate　the　magnetic　anisotropy　of　the　material.　Finally,　the　microstructures　of　4　materials　were　observed　with　a　metallographic　microscope.　The　microtextures　of　local　areas　were　measured　with　the　electron　backscatter　diffraction　(EBSD)　technique.　The　MBN　experimental　results　obtained　under　different　detection　parameters　showed　significant　differences.　The　optimal　MBN　detection　parameters　suitable　for　magnetic　anisotropy　research　were　determined　and　the　experimental　results　were　consistent　with　the　results　of　MCE　model.　The　study　indicated　that　MBN　technology　was　applicable　to　evaluate　the　MCE　of　pipeline　steel　and　oriented　silicon　steel,　especially　pipeline　steel.
