The formation and model of graphite crucible

  Graphite crucible formation and types of graphite crucible is in crystalline form of natural graphite as the main raw material, plastic refractory clay as binder, with different kinds of clinker with and made the main application of anti flint graphite crucible smelting special alloy steel, molten non-ferrous metal and alloy. In terms of the performance and use of the product, the graphite crucible is a component of the refractory material.

  Graphite crucible formation and types of graphite crucible is in crystalline form of natural graphite as the main raw material, plastic refractory clay as binder, with different kinds of clinker with and made the main application in smelting special alloy steel, molten non-ferrous metal and its alloy refractory graphite crucible. In terms of the performance and use of the product, the graphite crucible is a component of the refractory material.

  The crucible can be divided into three categories: graphite crucible, clay crucible and metal crucible. In graphite crucible, there are three kinds of graphite crucible and special graphite crucible and high pure graphite crucible. Various types of graphite crucible, due to different properties, uses and conditions of use, the use of raw materials, production methods, process technology and product model specifications are also different.

  Crucible type specifications are more, in the application is not limited by the size of the production, batch size and the variety of smelting materials, can be arbitrary choice, strong applicability, and can ensure the purity of the melting material.

  1, after placing the dry place, avoids rain intrusion; use before the slow bake to 500 degrees Celsius can be used.

  2, should be based on the crucible capacity feeding, avoid squeeze too tight, so as to avoid the metal thermal expansion of the crucible.

  3, remove the molten metal, the best use spoon to scoop out, to minimize the use of calipers, if using calipers and other tools should and crucible shapes consistent, to avoid local stress and shorten the service life. 4. The service life of the crucible is related to the use of the method. It should avoid the strong oxidizing flame directly spray to the crucible, and make the crucible raw material oxidation. Graphite crucible, because of its excellent performance, so in metallurgy, casting, mechanical, chemical and other industrial sectors, is widely used in the smelting of alloy tool steel and non-ferrous metals and alloys. And has good technical and economic results.

  Crucible are divided into three categories: the first class copper crucible, its specification "," and; the second category for copper alloy crucible, the super round a number 100, round number 100, the crucible with a third steelmaking, number 100.

  Crucible size , usually expressed in the order of size, 1 crucible with a volume of molten 1000g brass, the weight of 180g. The calculation of melting amount of crucible in melting of different metals or alloys can be used to calculate the bulk density of the crucible and to multiply the corresponding metal and alloy coefficients.
