Abstract

"MéTODO E APARELHO PARA PRODUçãO SIMPLIFICADA DE PEçAS FUNDIDAS DE LIGAS DE ALUMìNIO TRATáVEIS TERMICAMENTE POR AUTO-ENVELHECIMENTO ARTIFICIAL". Um tratamento térmico simplificado na fabricação de peças fundidas de ligas de alumínio do tipo melhorado por envelhecimento, especialmente para cabeçotes de cilindro e blocos de motores de automóveis. As peças fundidas, depois da solidificação e extração de seus moldes, cada uma, têm uma parte do produto final (peça de trabalho) e uma parte de canal de saída de gases (esta sendo finalmente descartada como sucata). A parte da peça de trabalho da peça fundida é seletivamente temperada a partir de temperaturas de solubilização até cerca de 120<198>C por meio de jateamento de água ou de outro líquido apropriado, preferivelmente, uma névoa carreada por gás nas superfícies da peça de trabalho, mantendo-se ainda a parte do canal de saída de gases da peça fundida essencialmente sem jateamento a temperaturas relativamente bem superiores. Depois da têmpera, a reserva residual de calor então retida pela dita parte do canal de saída de gases, pela condução de calor interna, reaquece a parte da peça de trabalho e mantém tal parte da peça de trabalho por um período de tempo efetivo dentro da faixa de temperatura para um envelhecimento artificial, eliminando-se assim qualquer necessidade do forno de envelhecimento usado pela tecnologia anterior. Preferivelmente, a têmpera é feita imediatamente depois da extração da peça fundida do molde (sem o resfriamento natural, reaquecimento e tratamento térmico de solubilização padrões, todos antes da têmpera), eliminando-se assim também a necessidade de um forno de tratamento térmico de solubilização, requerido pela tecnologia anterior convencional."METHOD AND APPARATUS FOR SIMPLIFIED PRODUCTION OF ALUMINUM ALLOY CASTING PARTS FIXED BY ARTIFICIAL SELF-AGING". A simplified heat treatment in the manufacture of aging-improved type aluminum alloy castings, especially for cylinder heads and car engine blocks. The castings, after solidification and extraction of their molds, each have a part of the final product (workpiece) and a part of gas outlet channel (this is finally being disposed of as scrap). The workpiece part of the casting is selectively quenched from solubilization temperatures to about 120 ° C by blasting water or other suitable liquid, preferably a gas-borne mist on the surfaces of the casting. while still maintaining the gas outlet channel portion of the essentially blastless casting at relatively much higher temperatures. After quenching, the residual heat reserve then retained by said gas outlet channel portion by conducting internal heat reheats the workpiece part and maintains that workpiece part for an effective period of time within the workpiece. temperature range for artificial aging, thus eliminating any need for the aging oven used by prior art. Preferably, quenching is done immediately after extraction of the cast melt (without standard natural cooling, reheating and heat solubilization, all prior to quenching), thus also eliminating the need for a solubilization heat treatment furnace. , required by conventional prior art.
