Introduction to the production process of emery

Emery is a kind of artificially synthesized silicon carbide, which has good thermal conductivity, stability and wear resistance, so it is widely used in metallurgy, building materials, ceramics and steel industries. How much do you know about its production process? Here is a detailed summary for you:

⑴, raw material crushing

Hammer crusher is used to crush petroleum coke to the particle size required by the process.

⑵, ingredients and mixing

Batching and mixing is the process of weighing and mixing according to the prescribed formula. The platform is used for batching, and the concrete mixer is used for mixing. The batching and mixing operations of petroleum coke and quartz sand are carried out according to the process requirements.

⑶, silicon carbide electric furnace preparation

Electric furnace preparation is to refurbish and reorganize the furnace that was used last time, so as to put it into use again. The work content includes cleaning the bottom material of the furnace, repairing the electrodes, cleaning and repairing the furnace wall, removing the loading force and the first gear, checking and eliminating other defects of the furnace.

⑷, Furnace loading

Furnace loading is to fill the furnace with reaction material, insulation material and furnace core material according to the specified furnace material category, location and size, and build the melting furnace side wall with the functions of heat preservation and material storage.

⑸, power transmission smelting silicon carbide

After the smelting furnace is connected to the transformer, electricity can be transmitted. 15 minutes after the start of power transmission, an open flame is thrown to ignite CO, and the smelting process lasts for 170 hours.

The classifications of quartz sand

  1. Ordinary quartz sand: The surface of ordinary quartz sand seems to have a layer of yellow skin, and some have large particles and strong fire resistance. It is a kind of quartz sand processed by the manufacturer after using natural quartz ore in the production process, such as washing and drying. No impurities can be seen in the quartz sand through the second water treatment filtration. It is the best choice for chemical water treatment. It can block the sundries suspended in the water and maintain the quality and beauty of the water. 2. Refined quartz sand: Refined quartz sand is a mineral made by the manufacturer after carefully selected quartz stone. According to different requirements of users, the range used is also different. But generally the main use of refined quartz sand is in glass products, because refined quartz sand is refractory and precision casting, especially suitable for fireproof glass materials.

Chromite purification processing method

At present, chromium ores with industrial value are generally chromium-magnesia spinel or chromium-iron spinel minerals, which contain a large amount of chromium oxide, with a content of about 18% to 62%, and generally also contain metals such as aluminum and nickel. Its characteristics make the chromium ore beneficiation process present a rich and diverse state. Due to the properties of chromium, chromium ore beneficiation processes include gravity separation, magnetic separation, flotation, combined beneficiation, chemical beneficiation, etc. Commonly used in industry are single gravity separation, single magnetic separation, and gravity-magnetic combined beneficiation processes. In terms of equipment selection, shakers and jigs are mostly used in the gravity separation stage, while the equipment selection in the magnetic separation stage is determined based on the magnetism of the ore.

Sandblasting nozzle classification and use

Using high-pressure air as a power source to drive abrasive particles to hit objects within a certain range will produce a great impact. The function of the sandblasting nozzle is to spray abrasive particles on the object evenly and efficiently. Sandblasting nozzles can be divided into: straight hole sandblasting nozzle, Venturi sandblasting nozzle , double Venturi sandblasting nozzle, angle sandblasting nozzle Straight hole nozzle: There are only contraction section and straight section inside, the structure is simple and easy to manufacture. This kind of nozzle cannot overcome the vortex phenomenon existing at the inlet end, and the pressure loss is large; the abrasive velocity at the outlet is less than 100m/s under the pressure of 0.7MPa.
