Nanjing Welt Casting Materials Co., Ltd.

Nanjing Welt Casting Materials Co., Ltd.

Nanjing Welt Foundry Materials Co., Ltd. was established in 2008 and is composed of a group of foundry experts and engineers. The company is mainly engaged in the research and development of energy-saving casting materials, and has successfully developed rare earth calcium silicon manganese super deoxidizers, rare earth refining agents, metal liquid purification agents, dry powder casting alcohol-based coatings, riser heating agents, multi-functional slag removers, and water glass sands Agents and other energy-saving products. The products have been used by large and medium-sized foundry companies such as Shandong Ningyang Chuangyan Casting (Japanese), Nanjing Foundry Material Factory, Suzhou Huayi Foundry for many years, and they have agreed that energy saving is obvious, easy to use, and efficiency is significant.

The company's purpose is to develop new energy-saving products for the purpose of energy saving and efficiency improvement for users. Direct sales, reducing the costs of middlemen, and other means to benefit users, free trials, and free guidance for corporate satisfaction are the tenets. Markets of similar products are developed based on characteristics such as quality, effect, price, and service.


First, graphite broken carburizing agent

a. Increase the number of nodular graphite in nodular cast iron during inoculation to promote graphitization;

b. Increase the graphite nucleus of the molten iron and refine the graphite spheres to make it more uniformly distributed in the matrix;

c. It can reduce the use of pig iron, increase the use of scrap steel, and save raw material costs.

Second, the pretreatment agent

a. Solve the negative impact of the hot iron standing at high temperature in the electric furnace;

b. It has the effect of reducing the oxygen content in the molten iron, which can increase the absorption rate of Mg, increase the number of graphite spheres per unit area, refine the graphite spheres, and improve the roundness and spheroidization rate of graphite spheres;

c. Improve the distribution of graphite morphology and machining performance of castings;

d. Improve the sensitivity of casting wall thickness, make the structure dense, effectively improve the micro-constriction of the casting, purify the molten iron, reduce the slag inclusion, and improve the ability to resist decay.

Third, Ishikawa high-efficiency deslagging agent

a. The slag remover does not burst, spreads quickly and uniformly, and has strong slag accumulation ability.

b, effectively prevent slag inclusion defects in castings, improve the inherent quality of castings, improve the yield of castings, and reduce production costs;

c. Simple to use, reducing labor intensity and improving production efficiency,

d. The quality effect is much better than the imported slag remover. Give it a trial for free first, and buy it if the effect is good!

Fourth, rare earth refining and purifying agent

Rare earth refining agent is an indispensable material for the production of high-end products such as American, Japanese, and European high-quality steels, special steels, and nodular cast iron. It can completely eliminate casting defects such as inclusions, pores, and microcracks. At the same time, the white spots, white spots, and flies footprints that often appear on the nodular cast iron machining surface are solved. Use method and dosage: Use 2, 5 ~ 3 kg per ton of steel (hot metal), put it on the bottom of the steel ladle, and wait for 8 ~ 12 minutes after the steel (hot iron) has been washed, so that the activated substances in the rare earth refining agent are sufficient. Reaction, start pouring, low temperature fast pouring can be.

Five, Ishikawa brand rare earth calcium silicon manganese super deoxidizer

The main function is to remove various harmful inert gases in the molten metal, purify the molten steel, promote uniform organization, reduce inclusions, and refine and refine the grains.

Rare earth calcium silicon manganese super strong deoxidizer, the dosage is one thousandth, eliminating defects such as pores and pinholes in castings and improving mechanical properties!

Using the rare earth calcium-silicon-manganese super deoxidizer developed by the company and three tons of one ton of common deoxidizer in the market can greatly save the casting cost, and it is the first choice for casting enterprises to produce high-end castings.

Six, pouring (running) mouth heating agent

The pouring (riser) heating agent is our company's patented technical product. This product can improve the yield of molten steel, eliminate the phenomenon of loosening and shrinkage of the casting, improve the mechanical properties of the casting, and improve the filming grade of the valve body by more than one level. The direct economic benefits are obvious. (The reasonable use of 1 ton of heating agent can directly generate economic benefits of about 20,000 yuan). Usage and Dosage When the molten steel of the precision casting gate or the sand casting riser is filled with molten steel immediately (immediately), spray 1 or 2 public heat agents on the surface of the pouring (riser). Must cover the entire surface of the pouring (rising) molten steel! Do not wait until the steel (iron) has been watered. The purpose of adding the heating agent is to delay the solidification time of the molten steel on the surface of the pouring (riser) surface, and make the molten iron in the pouring riser fully fill the casting body under the effect of atmospheric pressure, so that the structure of the casting is more compact, and the pouring riser The weight is reduced. Generally, the yield of molten steel is increased by 10 to 15% after casting the steel with a heating agent. However, we must identify the products of Nanjing Welt Co., Ltd., must be sampled and tested on domestic gas stoves, and must be able to ignite, cut in the middle of 20 minutes after spontaneous combustion, and the source of fire is qualified and effective. Please pay attention to distinguish authenticity !!

Seven, alcohol-based dry powder coating

This product is an alcohol-based dry powder casting coating, which is mainly used in sand casting of cold hard resin sand and oil sand. It can effectively reduce the surface roughness of the casting, prevent casting defects such as sticky sand, sand inclusion, and trachoma, and improve Sand removal effect. It is a supporting material for resin sand, glass sand and other modeling molds. After using this product, the surface of the casting is smooth and the strength is increased, which avoids the common sand sticking and porosity of the casting, and improves the work efficiency. The rheological properties, suspension properties, gas-generating properties, crack resistance and high-temperature stability were all tested.
