High-chromium hammer can crush relatively hard material wholesale manufacturers of high-chromium hammer, choose 巩义鑫 Lee Heavy Industries, the company's technology level in the hammer foundry is very high, can fully meet the people in industrial production Demand for crushing work; because of the high chrome hammer is a use of high chromium materials hammerhead, mainly with very good wear characteristics, and the hammer also has a certain toughness composite hammer price, so it is a huge The impact of the time, but also can maintain stable performance, long life hammer so, for people to create a lot of value. High work intensity high-chromium hammer, work objects are relatively hard material composite hammer, so the process of working on how much composite hammer, friction and susceptible to great impact, if the hammer no good durability, it is easy to be worn, the need for frequent replacement, which not only affect the progress of the people work, but also increased the cost of inputs. Therefore, the use of high chromium wear-resistant hammer is necessary. 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: 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: uniform should not interrupt the cast composite hammer model, 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.
