Stomatal hammerhead common defects. Stomata are usually two situations: one is located in the inner and outer surfaces of different size hammer spherical bubble, characterized alone or gather together the inner wall of the hole is smooth: the other is dispersed in the hammer inside presence of small honeycomb pinholes. It is mostly concentrated in the thicker parts of the hammer, the whole surrounding pores relatively light. The reason we enumerate pores generated a bit. ①: Hammerhead casting gating system design is not correct, the molten metal vortex, entrapped gas. ②: Hammerhead bad mold exhaust gas can not escape from the mold open. ③: sand core or shell core exhaust is bad, stained with water or sand core shell core, gas is divisible. ④: When casting metal casting is uneven or interrupted flow into gas. Prevent air bubbles generated as follows. ①: improving the gating system design, such as the top note change antes antes change serpentine runner and so on. ②: clean up mold in the vent plug hammer: Increase mold exhaust passage. ③: sand core made the necessary exhaust passage. At the same time should ensure sand core, after the shell mold core and the hammer assembly of these exhaust passage with the outside atmosphere. ④: hammer wear should be dried sand core model, dry sand core, shell core careful not stained with water: the casting process of metal-based coatings make up after falling paint, the paint should be noted that the moisture has completely evaporated. ⑤: without interruption even when pouring, so as not to bring gas, in order to facilitate mold exhaust, can be tilted pouring. ⑥: reasonably require strict control of the hammer and pouring temperature. Basic introduction also known hammer crusher hammer crusher hammer, hammer is one of the core parts of hammer crusher, arranged in a hammer crusher rotor shaft wear hammer, hammer crusher at a high speed during operation direct hit material, eventually broken into suitable material size. Hammer crusher manufacturing process can be divided into two types: casting and forging hammer wear characteristics, but they are not the same degree of wear. Depending broken material, also used in different period plus coupled with appropriate heat treatment process, after heat treatment process of the hammer is more practical and durable than the average hammer forged parts. Hammer crusher can be divided according to the material types: high manganese steel hammer, double metal hammer, composite hammer, hammer gold teeth, the chromium alloy hammer, hammer and other hard alloy for use in the process right now. Carbide hammer on the wear resistance performance is good. Hammerhead is divided into forging and casting, which casting than forging the high cost, but also spend a lot of time, manpower and labor, but is different in Henan wear forging hammer, forging a short time, low cost, manpower is also low, so intersect the lower cost of casting, forging hammer there, durable, wear-resistant quality assurance as well as the appearance of good-looking, forging and manganese steel hammer used in all 65 manufacturing, we all know that tough of manganese steel.
