A: Manufacturer.We have our own factory.

A: Our company has been established for many years has established a perfect service system:
I. Positive communication at the early stage:
Reply to inquiry → send photos of company qualification → invite factory inspection → update quotation in time → keep track
II. Medium-term win-win cooperation:
Contract → deposit to prepare goods → loading and shipping → production follow up
III. Real-time cargo tracking:
Since the forwarder takes a copy of the bill of lading → inform the ship has sailed → balance payment charged → telex release of the bill of lading
IV. Regular return visit at later stage:
Search customer feedback → make summary → assign improvement plan → follow up service

We can provide you with the most professional industry evaluation and industry dynamic analysis.

A: Spheroidizers should be stored in dry and ventilated warehouses to avoid moisture and oxidation. After opening, unused spheroidizers should be sealed and stored in time to avoid contact with air and deterioration. At the same time, the quality and batch stability of the spheroidizer should be checked regularly to ensure the stable quality of the castings.

A: Spheroidizer is an additive used in the field of cast iron casting. Its main function is to crystallize the graphite in cast iron into spheres. The main components of spheroidizers include magnesium, rare earth, silicon, calcium, barium, iron and other elements. Common types include magnesium-silicon alloys, rare earth magnesium-silicon alloys, etc.

A: The main function of spheroidizers is to improve the mechanical properties of cast iron, especially plasticity and toughness. By crystallizing graphite into spheres, spheroidizers can reduce or eliminate free graphite in cast iron, making graphite distribution more uniform, thereby improving the strength, toughness and other properties of cast iron.

A: The spheroidizer commonly used in my country is ferrosilicon rare earth magnesium alloy. This spheroidizer combines the advantages of magnesium and rare earth, and has good spheroidizing ability and adaptability.

A: The commonly used spheroidizers abroad mainly include magnesium spheroidizers (such as pure magnesium and magnesium alloys) and calcium spheroidizers. Different countries and regions choose different types of spheroidizers according to their own resources and production needs.

A: Choosing a suitable spheroidizer requires considering factors such as the performance requirements of the casting, the composition and temperature of the molten iron. Generally speaking, the type and amount of spheroidizer should be determined based on specific process requirements and experience.

A: The spheroidizer should be added after the molten iron is melted and before pouring to ensure its full effect. Adding it too early or too late may affect its spheroidizing effect.

A: The amount of spheroidizer used should be determined based on specific process requirements and experience, generally 0.05%~0.15% of the steel weight. Too much or too little may affect the spheroidizing effect.

A: When using spheroidizers, the following matters need to be noted: Ensure that magnesium and scrap steel materials do not come into direct contact to prevent magnesium combustion loss; the spheroidizer should be fully mixed with molten iron to ensure that graphite can be evenly distributed; select the appropriate spheroidizer variety to ensure the quality and batch stability of the spheroidizer; pay attention to safe operation and avoid contact with eyes and skin.

A: The main performance indicators of spheroidizers include spheroidizing ability, resource richness, price, easy melting, adaptability to molten iron of various compositions and temperatures, spheroidizing reaction kinetic conditions, and spheroidizing processability.

A: Spheroidizers can increase the tendency of welds to produce "white" and hardened structures, and induce cracks in welds and heat-affected zones (especially fusion zones). Therefore, the weldability of ductile iron is worse than that of gray cast iron.

A: The spheroidizer may produce some harmful gases during the casting process, such as the smoke produced when magnesium burns. Therefore, it is necessary to pay attention to safe operation when using the spheroidizer and take corresponding protective measures.
