Ferrotungsten price chart for reference:

Ferrotungsten is delivered in blocks with a block size range of 10~130mm and less than 10×10mm. The amount of broken pieces should not exceed 5% of the total weight of the batch. The maximum size of individual blocks allowed in one direction is 150mm. The surface of the tungsten iron block should be smooth and clean, with no obvious non-metallic inclusions and rust spots on the cross section and surface.

The agglomeration method uses an open electric furnace that can be moved on rails and the upper section of the furnace body is detachable, and carbon is used as the reducing agent. The mixed charge composed of refined tungsten ore, pitch coke (or petroleum coke) and slagging agent (bauxite) is added to the furnace in batches. The metal refined in the furnace is generally viscous. As the thickness increases, the lower part gradually solidification. When the furnace is full, stop the furnace, pull out the furnace body, and remove the upper section of the furnace body to allow the agglomerates to condense. Then take out the clot, crush and finish it; pick out the edges, slag and unqualified parts and return them to the furnace for remelting. The product contains about 80% tungsten and no more than 1% carbon.
