 Stomatal hammerhead common defects. Stomata are usually two situations: one is located in the inner and outer surfaces of different size hammer hammer spherical bubble factory, which is characterized by single or gathering together of the inner wall of the hole is smooth: the other is dispersed in the hammer inside honeycomb the existence of tiny 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: sand core 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. High-chromium forging hammer is the life of high manganese steel hammer or hammer three times, but the price is 2 times or high manganese steel hammer forging hammer. A medium-sized hammer crusher, hammer about 240 kg daily (n = 24, each approximately 10 kg), according to 300 days a year to start hammer, hammer 72 tons annual consumption, according to 8500 yuan per ton , the annual consumption of 612,000 yuan, and needs to be replaced twice a day, hammer hammer pictures, which reduces the yield, increased labor intensity, if high chrome composite hammer, changed every 5-7 days, only 60 per day kg, only 18 tons per year, according to 18,000 yuan per ton, the annual cost of 324,000 yuan, compared to each hammer crusher hammer is only one year, for enterprises to save 288,000 yuan, if you have three Crusher a year, saving 864,000 yuan. Jaw crusher: a medium-sized jaw crusher if high manganese steel tooth plate, that is replaced every 15 days a year needs to be replaced 24 times, each time for an 480 kg, required to 11.52 tons per year, 8500 yuan per ton, the annual cost 97,920 yuan, if the use of high chromium complex life is high manganese steel tooth plate four times, 50 days replacement of a replacement six times per year, annual demand of 2.88 tons, 18,000 yuan per ton hammer model, the annual cost of 50,000 yuan , enterprises save more than 47,000 yuan, if the three devices, the annual savings for the enterprise more than 141,000 yuan. Crusher: a crusher if high manganese steel hammer 10 days to replace one, 30 times a year, each of 280 kg per year for an 8.4 tons, 8,500 yuan per ton, the annual consumption of more than 70,000 yuan; high chrome hammer, every year for the 5 times, 1.4 tons per year, 18,000 yuan per ton, the annual cost of 25,000 yuan, the annual savings for the enterprise 46,000 yuan. If three devices, each year for the enterprise to save 130,000 yuan. According to expert estimates, the use of high chromium castings, one-third of annual cost savings than the use of high-manganese steel castings! Welcome customers to visit our factory.
