introduction:Process and advantages of powder high speed steel There are two ways of making high speed steel,One is the traditional ingot casting,The other is made by powder metallurgy。Traditional smelting manufacturing is usually divided into secondary refining(EAF+LF+VD)Or electroslag remelting(ESR)Two kinds of process,The above method is due to slow cooling of the metal liquid,It will cause uneven segregation of alloy and coarse growth of alloy carbide,And affect the performance of high speed steel。Although subsequent hot work process,The casting structure of the ingot can be changed and refined,Reduce the adverse effects,But it does not eliminate the original casting tissue,Thus for physics and machinery
