Thoughts and suggestions on the application of vertical parting line in the foundry (Qufu Longxiang Smelting and Casting Accessories Co., LTD.) Because the vertical box-free molding line has the advantages of fast production time, low cost and small human factor influence, it has been widely used in various founds.
The influence of hot sand on the moisture and mucous membrane effect in sand casting (Qufu Longxiang Smelting Accessories Co., LTD.) is known through the understanding of sand casting process
Analysis and prevention of the main defects of gray cast iron caused by core molding (Qufu Longxiang Smelting and Casting Accessories Co., LTD.)
Key measures for gray cast iron production (Qufu Longxiang Smelting and Casting Accessories Co., LTD.) How to improve the internal and external quality of castings
Detail the little-known performance advantages of efficient molding sand powder (Qufu Longxiang Smelting and Casting Accessories Co., LTD.) First of all, when the sand powder is dissolved, it can be well combined with water
Performance requirements of sand powder raw materials (Qufu Longxiang Smelting Casting Accessories Co., LTD.) In order to better ensure the use effect of the product, the main production materials should meet the following performance requirements:
The main characteristics and application range of molding sand powder (Qufu Longxiang Smelting and Casting Accessories Co., LTD.) uniform particle size distribution, high purity, good dispersion, higher than the surface, with high temperature resistance of inert, high activity, is activated alumina;
The use method and advantages of slagging agent (Qufu Longxiang Smelting Casting Accessories Co., LTD.) slagging and slag blocking: effective slagging agent can be used in ladle, tundish and electric furnace.
The effect of graphite in gray cast iron on its properties (Qufu Longxiang Smelting and Casting Accessories Co., LTD.) The role of graphite has a duality and a side that reduces the mechanical properties
The role of silicon in cast iron (Qufu Longxiang Smelting and Casting Accessories Co., LTD.)① The carbon content at eutectic and eutectoid points decreases with the increase of silicon content; (2) The addition of silicon results in a three-phase coexistence zone of eutectic and eutectoid transitions.
