Calcium Carbide Furnace

What is Calcium Carbide

It’s chemical name is calcium acetylide, molecular formula is CaC2, the appearance is gray, brown and yellow, black or brown bulk solid, it is the basic raw material in synthetic organic chemistry industry. Use calcium carbide as raw material, we can compose a series of organic compound and provide the raw material for industry, agriculture and medicine.
Main Application:

1. Calcium carbide can react with water and produce acetylene , the acetylene can compose many kinds of organic compound, such as synthetic rubber, synthetic resin, acetone, olefine ketone and carbon black, etc. Acetylene oxygen flame is widely used in metal welding and cutting.
2. While heating powdered calcium carbide and nitrogen, they react to produce calcium cyanamide, in other words is lime nitrogen. Heat the lime nitrogen and table salt to form calcium and sodium cyanides mixture, it usually be used in gold mining and heavy non-ferrous metal.
3. The calcium carbide can be used as desulphurizer in steel industry.
Production technology of calcium carbide: Generally, we often use electrothermal process to produce calcium carbide, namely, calcium lime and carbonaceous material (charred coal, anthracite or petroleum coke) in the carbide furnace, produce calcium carbide by the reaction of arc melting in high temperature.

Calcium Carbide Furnace

Q:What is the difference between industrial furnaces and boilers?: A boiler is a mechanical device for heating water into hot water or steam by the use of heat from fuel or other sources of energy. The original meaning of a pot is a water container heated by fire. The furnace is the place where the fuel is burned. The boiler includes two parts, the cooker and the furnace.

Q:What is an industrial furnace pit?: The creation and development of industrial kilns play an important role in the progress of mankind. Chinese appeared more perfect in the Shang Dynasty copper smelting furnace, furnace temperature is up to 1200 DEG C, up to 0.8 meters in diameter kiln stove.

Q:Should the industrial furnace shell cool down?: If the furnace shell temperature is too high, it shows that the lining is not good or damaged, so it should be repaired in time. If you do not repair, take the cooling way, undesirable. Because this will cause a lot of heat loss, resulting in waste of energy, increase production costs, and affect the service life of the furnace.

Q:Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.: The main equipments of heat treatment are classified into two major categories: main equipment and auxiliary equipment. The main equipment includes heat treatment furnace, heating device, surface modification, surface oxidation device, surface mechanical enhancement device, cooling equipment, cold processing equipment, process parameter detection and control instrument; auxiliary equipment includes cleaning cleaning equipment, furnace atmosphere heating medium permeability meter preparation equipment, cooling device, quenching medium heavy transport machinery, quality testing equipment, power transmission line and auxiliary equipment, fire safety equipment, dust and other production fixture.

Q:How to use industrial furnace equipment?: When the furnace is used, the lifting mechanism of the furnace door must be in good condition, and the wire breakage of the steel wire is not allowed to exceed the designated value. The weight should be properly allocated, and the drive department shall be provided with a protective cover.

Q:Why does the burner of industrial furnace burn occasionally?: The general process for burner ignition, blowing furnace, electric spark ignition, solenoid valve, open the gas in case of delayed spark ignition, detection device detects the flame, the controller accepts signal so that the solenoid valve open, gas continuous normal combustion. However, if the ignition fails or the burner fires, the detector cannot detect the flame, which causes the solenoid valve to close and the burner flameout.

Q:What are the companies in the world that are currently engaged in metallurgical furnaces?: Each manufacturer has its own industry and technological advantages.If you say that the performance rankings, turnover, and so on, it seems that no one has done this ranking.

Q:Brief introduction to repair of industrial furnace: The industrial furnace is the main production equipment in the machinery industry. The repair of industrial furnace directly affects the quality, high yield, long life, low consumption and safe production of the furnace.

Q:Selection of heat preservation material for industrial furnace: Micro nano heat insulation board.The thermal conductivity of micro nano heat insulation board is very low, only a fraction of the traditional thermal insulation material, and the insulation effect is very efficient.

Q:How many kinds of industrial electric furnaces are there?: Electric furnace is divided into four categories: resistance furnace, induction furnace, arc furnace and special electric furnace according to the different ways of electric heating.
