Graphite crucibles have excellent thermal conductivity and heat resistance during the pre application inspection work. During the entire high-temperature application process, the linear expansion coefficient is small, and they have certain strain resistance performance for rapid heating and quenching. Strong corrosion resistance to acid and alkaline solutions, with high-quality organic chemical reliability. It is widely used in metallurgical industry, forging, mechanical equipment, chemical plants and other industries for smelting alloy tool steel, rare metals, and aluminum alloys, and has good practical safety engineering effects.

Generally speaking, in the inspection work of graphite crucibles before application, the following key aspects should be ensured:

1. The first step is to check the graphite crucible for cracks before work. If there are no cracks, the graphite crucible needs to be heated to 600 ° C and dried sufficiently.

2. There should be no water stored around the furnace or in the pit in front of the furnace, and unrelated objects should not be piled up around the graphite crucible.

3. Strictly inspect the waste from the furnace for any explosives, and ensure that the waste is heated and dry. The speed of adding graphite crucibles should be slow.

Before applying graphite crucibles, it is necessary to do a good job in the following aspects. The regulations on the flame retardancy of graphite crucibles are very high, therefore, it is necessary to have the fire resistance and compressive strength of the raw materials of graphite crucibles during meals in order to make graphite crucibles more safe for use; People often apply graphite crucibles to various organic chemical smelters with strong corrosion, therefore, the reliability of organic chemistry for graphite crucibles is also crucial to reduce erosion; The strength and ductility of graphite crucibles are also factors that must be considered to prevent brittle fracture in applications.
