Description
Technical field
The present invention relates to a kind of continuous cast mold that has heat pipe cooling system, belong to continuous cast mold cooling technology field.
Background technology
Casting process is that molten steel is injected in the crystallizer, obtains the process of strand continuously.It is the intermediate link that connects steel-making and steel rolling, is the important component part of STEELMAKING PRODUCTION.Traditional crystallizer is the copper sheathing of the no end of a Forced water cooling, and it is very important parts during continuous casting is produced, and plays an important role in continuous casting production, is called as " heart " of continuous casting installation for casting.Molten steel tentatively condenses into the profile of strand in crystallizer, forming has certain thickness base shell, under the comprehensive function of mechanical stress and thermal stress, neither can be broken defectives such as also unlikely generation torsional deformation to guarantee strand.In order to obtain to form the needed thermograde of initial solidification base shell, select for use circulation that the crystallizer copper wall is cooled off usually, this has brought a series of problem to continuous casting production process.Because the temperature of crystallizer is higher, the cooling water of crystallizer copper sleeve inside is heated and will produces the steam of a part, the existence of these gases has destroyed contacting of cooling water and crystallizer inwall, influenced the exchange heat between cooling water and the crystallizer, when cooling water flow acquires a certain degree, augmented flow will no longer have a significant effect to cooling effect, and the thickness of initial solidification base shell does not have significant change yet at this moment, and this has just restricted the raising of casting speed.In addition, the tank of crystallizer inwall is also stopped up by field trash and incrustation scale easily, and this has also influenced cooling effect.
Summary of the invention
The purpose of this invention is to provide a kind of continuous cast mold heat pipe cooling system, that have the good heat transfer effect that has.
Heat pipe is the fabulous super heat conducting element of a kind of heat-conducting effect, and the capacity of heat transmission surpasses hundreds of times even thousands of times of copper.It can be at small temperature range internal reaction, and the Temperature Distribution of regulating length direction is automatically promptly transmitted heat, often is considered to the isothermal element.If hot pipe technique is applied to above-mentioned continuous cast mold cooling system, will improve the cooling effect of crystallizer undoubtedly, increase the thickness of initial solidification base shell, thereby improve casting speed.
The present invention is a kind of continuous cast mold that has heat pipe cooling system, includes: submersed nozzle, continuous cast mold copper pipe, cooling jacket, heat pipe; It is characterized in that: crystallizer copper pipe is positioned at the centre of whole device, and heat pipe couples together crystallizer copper pipe and peripheral cooling jacket; The end that heat pipe is connected with the continuous cast mold copper pipe is an evaporation ends, and the other end of heat pipe is connected with cooling jacket, and this end is a condensation end; Heat pipe has many groups, is distributed in wide and the leptoprosopy in the crystallizer copper pipe outside respectively; As required, the quantity of the arrangement mode of heat pipe and every group of heat pipe can be different; Be certain included angle between the outer surface of the axis of heat pipe and continuous cast mold copper pipe.
Described heat pipe is gravity assisted heat pipe or the core heat pipe is arranged, is the inclination arranged in form; The case material of described heat pipe is copper, aluminium or stainless steel; Selected working media is a methyl alcohol.
Described heat pipe can preferentially be chosen as the core heat pipe, and this heat pipe is provided with the imbibition core at the inwall of its housing, by this imbibition core, can make working media be back to evaporator section in the liquid nationality capillarity of condensation segment.
The characteristics of apparatus of the present invention are to utilize heat pipe cooling system to realize cooling to continuous cast mold, thereby reach the purpose that improves the mould temperature gradient, compare traditional water cooled copper mould crystallizer, and effect of the present invention is more superior.
