Abstract
The present invention relates to metallurgy engineering, and is especially heat pipe type continuous casting crystallizer, which consists of crystallizer, crystallizer cooling slit, vapor pipe, condensator, liquid returning pipe and heat pipe medium, and utilizes heat pipe with ultra heat conductivity to take out the latent heat of the molten metal inside the crystallizer for fast cooling and crystallizing. After molten metal is poured into the crystallizer, its latent heat penetrates the inner wall of the crystallizer to evaporate the medium in the heat pipe heating section inside the crystallizer cooling slit so that great amount of heat is absorbed, and the produced vapor passes through the vapor pipe and enters to the condensator for cooling into liquid returning through the liquid returning pipe to the heating section, so as to complete the heat pipe circulation while crystallizing the molten metal fast.
Description
Technical field:
The title of patent of the present invention is: hot pipe type continuous casting crystallizer is the latent heat that a kind of superior heat conductivity that can utilize heat pipe under waiting temperature state is taken away motlten metal in the crystallizer, makes the device of liquid metal rapid solidification crystallization, belongs to the metallurgical engineering field.
Background technology:
Being extensive use of continuous casting technology at metallurgy industry at present, promptly is with the metal injection crystallizer of molten condition, utilizes water to come the cooler crystallizer inwall, the latent heat of solidification of liquid metal is taken away, thereby made it the metal base that crystallization forms required specification.This technology can be saved this operation of breaking down, but owing to cooling system structure complexity, water cooling will consume a large amount of water ， Tong Time and also can pollute environment, the operation operation is all inconvenient; Particularly,, use water as the danger that cooling medium also has combustion explosion as magnesium metal to some active metals.
Summary of the invention:
In order to remedy above-mentioned the deficiencies in the prior art, patent of the present invention can provide a kind of superior heat conductivity of utilizing heat pipe under waiting temperature state to take away the latent heat of motlten metal in the crystallizer, makes the hot pipe type continuous casting crystallizer of liquid metal rapid solidification crystallization.Its technical scheme is: it is made up of crystallizer, bringing-up section, steam pipe, condenser, liquid back pipe and heat-pipe working medium; The steam pipe outlet on crystallizer top and steam pipe inlet be UNICOM fixedly, the outlet of steam pipe and condenser inlet be UNICOM fixedly, condensator outlet and liquid back pipe inlet be UNICOM fixedly, the liquid back pipe inlet of the liquid back pipe port of export and crystallizer bottom is UNICOM fixedly, and in bringing-up section, charge into heat-pipe working medium, make heat-pipe working medium can be in turn along bringing-up section, steam pipe, condenser, liquid back pipe, flow back to bringing-up section and form circulating in the closed system.Can realize the balance of conducting heat by the heat output of selecting different crystallizers and adjustment condenser for use to different setting rates and different kinds of metals.Continuous casting gives the brilliant device course of work as follows: when motlten metal is molded in the crystallizer, its sliding heat is passed the crystallizer inwall rapidly and is made working medium carburation by evaporation in the heat pipe bringing-up section, absorb a large amount of heat, the steam that is produced enters condenser along steam pipe, after in condenser, being cooled to liquid, flow in the bringing-up section again along liquid back pipe and to be heated, its heat output can be regulated and control by the heat dissipation capacity of condenser, when finishing the heat pipe circulation with the motlten metal rapid crystallization.
Description of drawings:
Fig. 1. be the hot pipe type continuous casting crystallizer structure diagram.
Wherein: the 1--crystallizer; The 2--crystal plane; The 3--bringing-up section; The outlet of 4--steam pipe; The 5--steam pipe; The 6--condenser inlet; The 7--condenser; The 8--condensator outlet; The 9--liquid back pipe; The 10--heat-pipe working medium; The outlet of 11--liquid back pipe.
The outlet 4 of the steam pipe on crystallizer 1 top is through the fixing UNICOM of steam pipe 5 and condenser inlet 6, condensator outlet 8 and liquid back pipe 9 be UNICOM fixedly, the liquid back pipe outlet 11 of the outlet of liquid back pipe 9 and crystallizer 1 bottom is UNICOM fixedly, all junction are not all closely leaked and charge into heat-pipe working medium 10 in the formed bringing-up sections 3 of crystallizer slit, when bringing-up section was heated, heat-pipe working medium was just in turn along flowing in bringing-up section 3, steam pipe 5, condenser 7, the liquid back pipe 9 formed closed-cycle systems like this.When motlten metal is molded in the crystallizer, closely contact with the crystal plane 2 of crystallizer, its Latent heat is passed the crystallizer inwall rapidly and the heat-pipe working medium 10 in the formed bringing-up section of crystallizer slit is evaporated, the steam that is produced enters condenser along steam pipe, after in condenser, being cooled to liquid, flow back to bringing-up section again along liquid back pipe, thereby finish the heat pipe circulation.
