Product description

Liquid metal is continuously poured into the crystallizer at one end and then molding material is continuously pulled out from the other end, this is called continuous casting method. Continuous casting can be used for producing copper, steel, aluminum, zinc, gold, silver and other alloys of the same cross-sectional shape and larger length of castings. Crystallizer is like the heart to a continuous casting apparatus. Currently non-ferrous metal casting generally uses graphite material with good heat conductivity and strength.

1. Continuous casting graphite mold has good high temperature performance; it can remain stability under high temperature, thus greatly reducing the chance of thermal expansion and contraction, which current can be regarded negligible.
2. Graphite has good lubricating properties and during solidification liquid metal generally does not stick to the graphite mold.
3. Graphite has good thermal conductivity, wear resistance and high mechanical strength, which allow graphite mold to play an increasingly large role in modern technology.
Under current demand for increasing technology of industrial production, Top-Carbon achieves the best effect of continuous casting by selecting suitable graphite material and launching a new production process. After oxidation resistance and wear loss treatment, Top-Carbon graphite crystallizer can solve the problem of short service time and greatly improve customer production speed and reduce production costs.
Applications:copper, aluminum, zinc, alloys and other non-ferrous metal continuous casting

Product description

 During casting, gray cast iron and other metal is often used as a chilled material, since the thermal conductivity of gray cast iron and other metal is small (2.0-2.5 kcal / m. H. Degree), often when external casting has solidified, the interior is also in liquid state. After some time, although internal solidifies, because of the reduced internal volume upon cooling and solidification, often results in defects of internal surface depressions and loose texture.
I. Graphite cold iron advantages:
1. To make outer and inner casting simultaneously cooling as soon as possible: Since the thermal conductivity of graphite cold iron is large, it can absorb more heat in a short time. Outer and inner casting simultaneously quick cooling not only solves the problem of loose texture and shrinkage of hot spot, but also enables the casting microstructure of fine paralytic sheet reach more than 95% and the number of eutectic reach up 450-550cm. At the same time casting hardness can be improved 20-50HB, finish and wear resistance of casting surface is also improved.
2. Graphite cold iron easy to operate: Due to small proportion of graphite cold iron, about 1/5 of metal cold iron, it is light to carry and sand (core) does not easily fall off when turning the box.
3. Graphite cold iron is reusable with low cost: Since graphite cold iron refractoriness is up to 2800 degrees Celsius, it can withstand high temperatures and does not easily get oxidized. Graphite cold iron not only avoids casting white spot (cementite) and porosity and other casting defects, but also has the properties of not easily getting damaged, oxidation, and cracking. The service life is 5 to 10 times longer than cast iron and cold iron of other metal materials.

II. How to use graphite cold iron materials:
In hot spots required chilling graphite cold iron molding (core) is placed with thickness of 0.6 to 1 times of hot spot diameter. If used on cast iron parts, graphite painting should be painted on cold iron; for bronze pieces graphite or talcum powder can be painted to prevent carbon increase, and then the casting pieces will be dried to achieve better effect. graphite cold iron material is made of special processing with fixed carbon content of more than 99% and the advantages of light in weight (specific gravity 1.6-1.9 g / cc), high refractoriness (2800 refractoriness degrees) and high thermal conductivity coefficient (21 kcal / m . h. degree) and so on. So Top-Carbon graphite iron uses cold chilling cold iron material instead of metal materials, can solve the defects of casting loose and shrinkage of steel, cast iron, copper and aluminum problems. And it can effectively solve the casting defects of white spot and ail hole by using metal cold iron

Product Description

 Aluminum liquid purification process is the main means to improve the overall performance of aluminum alloy. In the cleaning process, purified gas is mixed with solvent and then is blown to molten aluminum by the rotation of graphite rotor. Such purification treatment method is currently the most advanced treatment method in the world. Durable design and production of graphite rotor works as follows: the rotation rotor will break nitrogen (or argon) into a large number of dispersed bubbles and then blow the bubbles into molten aluminum, and disperse them in the molten metal. By the gas partial pressure and surface adsorption principle, bubbles in the molten metal absorb hydrogen and oxide slag, which is then taken out of the melt surface to be purified with the rise of bubbles. Due to the dispersed bubble uniformly mixed with the rotation, and floating spiral rotating slowly and contact with the melt for long time, without forming a continuous straight up air flow, thus the purification effect is significantly improved.
Product Features:
1.graphite rotor spinning nozzle is made of high purity and high density graphite, in addition to considering that the structure of the nozzle should break the bubble, but also considering that the use of molten aluminum alloy centrifugal force generated by agitation needs to evenly mix with ejected gas to form gas / liquid flow ejection, and increase the contact area and contact time of the bubble and the liquid aluminum alloy to improving gas purification effect.
2.Graphite rotor speed can be adjusted by inverter control with stepless adjustment up to 700r/min. Graphite rotor specifications are for Φ70mm to 250mm, impeller specifications are for Φ85mm to 350 mm. High-purity graphite rotor has characteristics of antioxidant with high strength, high temperature resistance and corrosion resistance to aluminum flow. In gas purification process, the surface of liquid aluminum in the box is covered with a nitrogen blanket protection to expose portion of graphite rotor in an inert gas to prevent oxidation of the rotor in high temperature and prolong the service life of the rotor.
3.The impeller shape is streamlined, thus the friction force can be reduced during rotation. The friction between impeller and liquid aluminum is relatively small. Therefore, the gas removal rate can reach more than 50%, thus shortening smelting time and reducing production costs.
4.The surface of graphite rotor is designed with special anti-oxidation treatment and the service life is about 5 times that of ordinary products. Such rotors are widely used in aluminum foundry industry.
5.The use cycle can reach up to two months in aluminum foil casting, alloy wheels and other aluminum industry.
Economic aspect:
For aluminum foundry and aluminum products plant, the important point is to reduce processing costs. In this regard, Top-Carbon graphite rotor can bring the following benefits:
1.reducing the cost
2.reducing the consumption of inert gas
3.reducing the amount of aluminum-containing slag
4.lower labor costs
5.to improve performance and extend the replacement cycle
6.to improve reliability and reduce maintenance costs
Design and Order:
Because graphite rotor specifications used in each casting or casting production lines are not the same, the price is different. First, the original design drawings and graphite rotor environment survey are provided and completed by the customer. Then, Top-Carbon conducts technical graphite analysis based on rotor speed, direction of rotation and relative position of liquid aluminum surface, and make appropriate erosion resistance antioxidant treatment plan and quotes the corresponding price.
