The application of scales graphite in the casting industry

Scales graphite is widely used in industry, especially the casting industry. In the production process of the casting industry, the casting process is carried out at high temperature environments. In order to prevent castings from deforming or broken at high temperatures, special casting scales need to be added to add cast materials and add casting materials. After the scale graphite, it can resist high temperature to ensure the quality of the casting. The following editor of graphite manufacturers will introduce the important application of scales graphite in the casting industry:There are many specifications for casting scales for castings, 600 meters ~ 800 mesh, 1200 mesh and other specifications for casting dedicated graphite. In different casting production fields, special casting scales of different mesters need to be used. Graphite helps the product to complete faster and better, and improve the quality of the casting products. Therefore, the scale graphite of the cast plant is

Inspection of graphite crucibles before application

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
