Popis:	In order to obtain sound cast components with good properties, a number of measures must be taken to make parts defect free. It is well recognised by the casting industry that it is essential to control cooling rates of permanent mould castings in order to speed up solidification and control the solidification pattern. Each of the traditional controlled cooling techniques (air or water cooling passages and chill inserts) presents certain disadvantages and none offers optimum thermal management. A new cooling method for permanent moulds is proposed. This new technique is based on heat pipe technology that was developed specifically for the cooling of permanent moulds in the casting of light metals where high heat fluxes are normally encountered. The influence of the conductivity of mould coatings on casting solidification and dendrite arm spacing with heat pipe cooling was investigated. Typical experimental results are also presented.
