Technical field the utility model relates to a kind of manufacturing equipment of chemical products boron carbide, i.e. boron carbide adjustable arc smelting furnace.
The background technology boron carbide is a kind of nonmetal infusible compound, with B
4C is a staple, is one of superhard manufactured abrasive, and hardness is only second to diamond, and the diamond Mohs' hardness is 10, and boron carbide is 9.36.And characteristics such as have that the grinding of being suitable for, physicochemical property are stable, light weight, nonferromagnetic substance are good, react hardly with soda acid, the performance that also has semiconductive and intercept neutrons, be the desirable substitute material of diamond, boron carbide micro powder and boron carbide product are widely applied to fields such as aviation, military project, nuclear industry, wear-resisting, refractory material.
At present, the main production equipments of boron carbide is an electric smelting furnace.Electric smelting furnace has three electrodes to insert in the stove, produces powerful electric arc between the electrode, sends huge heat, raw material is decomposed and reorganization chemical combination rapidly.Because the position of electrode is very big for the influence of conditions at the arc, therefore, the position of the three-phase electrode of existing electric smelting furnace and the utmost point heart diameter of a circle that is constituted are based on most applications and definite parameter is changeless., because the situation in the electric arc furnaces changes, this changeless structure is difficult to adapt to various situation.For example: electric arc is difficult to form when electrode begins to charge, and needs to add striking Jiao and could form electric arc.In smelting process, temperature height in the utmost point heart circle, the outer temperature of circle reduces gradually, thereby inside and outside reaction speed differs greatly, and when the middle part reaction was finished, the periphery reaction was not finished as yet.The outside reaction has been finished, and the middle part is burning.Therefore, not only power consumption is big for existing boron carbide electric smelting furnace, and product quality is relatively poor, and the many index of product is lower than international standard.
The summary of the invention the purpose of this utility model provides a kind of difficult problem that can solve the reaction speed inequality that occurs in the boron carbide smelting process, and the boron carbide adjustable arc smelting furnace that can reduce power consumption significantly, reduce cost, improve the quality of products.
Above-mentioned purpose is realized by following technical scheme: develop a kind of boron carbide adjustable arc smelting furnace, constituted by the arc-spark stand that body of heater, electrode and folder hang electrode, its arc-spark stand also is to constitute by base, hoist engine, column and along the lifting platform that column slides up and down, conducting rod and supporting arm are housed on the lifting platform, electrode holder is held in the cutting ferrule of supporting arm front end, different is: between the cutting ferrule of said holding electrode and the supporting arm by rotating shaft hinge mutually, also be provided with puller on lifting platform, cutting ferrule can swing around the shaft under the drive of puller.
Said puller is to be made of cylinder, pull bar and vertical rod, and the tail end of cylinder is fixed on the sliding sleeve of lifting platform, and the cylinder piston rod front end links to each other with pull bar, and the other end of pull bar and the upper end of vertical rod be hinge mutually, and the lower end of vertical rod is fixed on the cutting ferrule top.
Adopt the boron carbide adjustable arc smelting furnace of technique scheme, can adjust distance between electrodes at any time, change utmost point heart diameter of a circle, thereby omitted striking Jiao, dwindled the temperature difference of each point in the electric arc furnaces, make the raw material reaction equilibrium, guaranteed product quality, reduced power consumption and production cost significantly.
