(13) Less pollution: the relationship with the melted metal and process characteristics are fully considered in the material design, and harmful impurities are almost or completely not brought in& nbsp;

(7) Anti adhesion: because graphite is not easy to adhere to molten soup, the penetration and adhesion of molten soup are less& nbsp;

(8) Very little metal pollution: the strict control of the material composition ensures that the graphite crucible does not pollute the metal during dissolution. Improve the material formula of the predecessors, and effectively resist the melting

Physical and chemical action. It has a certain strength against mechanical impact (when molten materials are put into use, etc.)

(3) High heat resistance: high temperature resistance, high temperature resistance& nbsp;

(4) Corrosion resistance: strong corrosion resistance to molten soup; The average fine matrix design delays the corrosion of the crucible.

500 silicon carbide for intermediate frequency furnaceCopper melting crucibleThe main characteristics are listed as follows:

(1) Fast heat conduction: due to the use of graphite and other raw materials with high thermal conductivity, the melting time is shortened; Using high thermal conductivity materials, the structure is compact, the apparent porosity is low, and the thermal conductivity is fast.

(2) Strong thermal shock resistance: the graphite crucible has strong thermal shock resistance and is not easy to crack for rapid cooling and heating; The thermal shock strength it can withstand is extremely high, so any process treatment can be carried out with confidence& nbsp;

There are many models and specifications of aluminized graphite crucibles, which are not limited by the production scale, batch size and variety of smelting materials. They can be selected arbitrarily, with strong applicability and can ensure the purity of the melted materials& nbsp;

Application scope: smelting various non-ferrous metals such as gold, silver, copper, aluminum, lead and zinc, as well as various non-ferrous metal alloys and various rare metal alloys& nbsp;

(14) Energy saving and environmental protection: fast heat conduction can save a lot of fuel and reduce waste gas pollution& nbsp;

Silicon carbide graphite crucibleIn terms of raw materials, manufacturing and other aspects, we have taken as many measures as possible to satisfy the use under the cruel premise. Low porosity, (11) high strength: select high-quality materials, high-pressure pressing, reasonable combination, good high-temperature strength, scientific product shape, and high pressure bearing capacity. Good crack resistance. Therefore, it maintains the original physical and chemical characteristics of natural graphite.

Therefore, it is strongly recommended that if you use coke furnace, oil furnace and gas furnace for heating and smelting, you use our graphite crucible. Graphite crucible can be considered as low cost and high efficiency for your enterprise in terms of smelting and heating methods such as coke furnace

The main raw material of the aluminized graphite crucible produced by Jebsen crucible is crystalline natural graphite. Average tissue structure and high strength. The quality of this crucible is 3-5 times higher than that of ordinary domestic crucibles and more than 80% higher than that of imported crucibles& nbsp;

6) Oxidation resistance: the surface is treated with an oxidation-resistant glaze layer, and the graphite is easily oxidized at high temperature in the oxidation mist. Due to the oxidation prevention treatment, the oxidation consumption is less; Improve the oxidation prevention mechanism of the predecessors, so that the graphite in the crucible is well protected and the structure is fine& nbsp;

Supporting furnace types: electromagnetic induction furnace, resistance furnace, intermediate frequency induction furnace, biological particle furnace, coke oven, oil fired furnace, natural gas furnace

Service time: for molten aluminum and various aluminum alloys, the service time is more than six months& nbsp;

(12) Less slag sticking: the amount of slag hanging on the inner wall is small, which greatly reduces the heat resistance and the possibility of expanding and cracking the crucible, and always keeps the capacity Zui large. Reasonable resistivity, induction heating can significantly reduce reactive power consumption& nbsp;

Aluminum graphite crucibles are supplied from the spot,Graphite crucible for melting aluminum, graphite crucible for refining aluminum, graphite crucible sales

If smelting copper and aluminum is used in electric furnaces and intermediate frequency furnaces, choose silicon carbide crucibles. However, if it is used in coke furnaces, oil furnaces and natural gas heating methods, our company recommends that customers choose graphite crucibles produced by our factory. Because the cost of graphite crucibles is three or four times lower than that of silicon carbide crucibles, and if you smelting copper and aluminum in coke furnaces, you can't perform the good function of silicon carbide crucibles, And the service life is only more than ten more heats than that of a graphite crucible. Namely:Graphite crucibleIt has good thermal conductivity and high-temperature resistance. In the process of high-temperature use, it has a small coefficient of thermal expansion and a certain strain resistance to rapid heating and cooling. (the main reason is not to add iron in the molten soup);

(9) Long service life: compared with ordinary clay graphite crucible, it can improve the service life by 3 to 5 times in terms of different materials& nbsp;

(10) High density: adopt the isostatic pressing process that improves the predecessors, and the material is dense and even, without defects. We look forward to the cooperation of users at home and abroad. We will provide you with our best services. Superior melting loss and oxidation resistance. Shorten dissolution time, save energy and increase efficiency. It has strong corrosion resistance to acid and alkaline solutions and excellent chemical stability.
