In order to improve the high chrome hammer surface refractoriness, chemical stability, anti-metal erosion resistance, sticky sand and other properties and applied in its core surface mold cavity or an overlay material. Its specific role is as follows: 1, to reduce the surface mechanical and chemical sticky sticky sand sand; 2, to reduce the surface sand and washed sand; 3, to improve the surface properties and internal quality high chrome hammer. In the original production of composite hammer hammer forging hammer on classification, beyond the conventional adding a lot of precious and rare alloy can produce a harsh abrasive wear resistance, This is described in detail on the composition of its knowledge mold forged hammer I hope you like it. A casting injection systems: liquid metal flows into the cavity of the channel, which is generally by pouring cup, sprue, runner, runner components. 2, outlet eye: in composite hammer mold or mandrel with a needle out of the outlet channel to vent. 3, vent: in which the mold or core for casting formed of a gas is discharged provided grooves or channels. 4, the riser: for feeding the mold cavity model casting with forging hammer, some also from observing the riser, exhaust and set slag role. 5, the cavity: the cavity part by the hammer mold forming material surrounded by, the main space is formed casting. 6, the core: sand casting part obtained in the interior cavity. Overhanging portion of the core, said core head for positioning and supporting the core. Secondary sand core is placed head cavity, said core holder.
