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: Improved composite hammer 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: sand core composite hammer manufacturers should be dried, 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. Clinker crusher hammer hammer preferred high-chromium alloy known that cement production is inseparable from limestone crushing to Wuhu Conch 2 × 12000t / d production line, for example, since full production, the demand for limestone materials multiplied, Japanese insurance requirements for It reached 80,000 tons, but limestone aggregate is the main raw material for cement production factory price composite hammer, limestone aggregate timely supply directly determine the capacity of the entire production line, the importance of limestone in cement production line shows. The hammer crusher is the best device limestone crushing, but because limestone silicon content have a strong abrasive, which resulted in an ordinary high manganese steel hammer wear very serious, frequent replacement of hammer crusher bring loss of operating costs and downtime are immeasurable. At present, China's cement production line in the most used hammer crusher main material: high manganese steel, high chrome hammer, alloy steel composite hammer difference, but according to different silicon content in limestone, hammer crusher The wear and tear is different, the selection of the most suitable material crusher hammer also be determined based on the composition of limestone. But after a number of cement enterprises of different materials hammer crusher hammer production proven, either from the replacement frequency, or on life in terms of the degree of wear, high-chromium alloy hammer is currently the best in the application of limestone hammer crusher. High-chromium alloy high manganese steel hammer hammer is more than three times the life, welcomed the choice of high-chromium alloy hammer.
