How to use Casting cast iron slag remover
In the casting process of Casting cast iron slag remover, due to the disordered charge added, the molten metal will produce various waste residues, which will seriously affect the quality of castings and reduce the product qualification rate.
Other Problems of Alkaline Phenolic Resin No-bake Sand Process
In addition to the problems in the regeneration of used sand, the Alkaline phenolic resin no-bake sand process has some shortcomings. When this process is used, corresponding measures should be taken to obtain better results.
Advantages of Alkaline phenolic resin no-bake sand process
1. The flue gas emitted during sand mixing, molding and pouring is less than furan resin sand with acid as hardener, resol Alkaline phenolic resin with acid as hardener and urethane resin sand with amine as hardener.
Hardening mechanism of Alkaline phenolic resin
In the hardening reaction of Alkaline phenolic resin, the base in the resin reacts with the ester first, forming the carbonate of the alkali metal, releasing the alcohol. After the alkali in the resin forms carbonate, it is in a reaction state, and a cross-linking reaction can occur at normal temperature to bond the sand grains, so that the molding sand has the necessary strength.
Function and usage of Casting cast iron slag remover
Casting cast iron slag remover slag removal and slag blocking: high-efficiency slag remover can be used in ladle, crucible boiler, electric furnace and reverberatory furnace.
What are the performance advantages of cast Casting cast iron slag remover
Cast Casting cast iron slag remover is generally used in cast iron. It is mainly used to gather the infusible material on the surface of the iron aqueous solution to make it easy to remove and ensure the purity of the iron solution. The slag remover can improve the yield of castings and reduce production costs. The method of use is simple. It is widely used in the cast iron industry.
What characteristics should a good Casting cast iron slag remover have
The quality control of Casting cast iron slag remover is strict, the active ingredients account for more than 96%, strictly control the dust and impurities in the product, strictly control the particle size range of the product, and ensure uniform particle size, avoid dust during use, and maintain a clean production environment.
