Increasing the utilization coefficient of metal in the production of valve balls

This article describes a production technology of blanks for valve balls which improves the utilization coefficient of metal. Pressing of the shaped blanks, which consists in combining forming and bending, is effected with punch and forming die on a hydraulic press model with a force of 4000 kN, with heating in a compartment-type gas furnace. It is determined that making the blank in a crosslike shape helps reduce metal expenditure per ball and improve the utilization coefficient of metal. The new technology for the production of valve balls with a rational sheet cutting pattern makes it possible to save 340 tons of rolled sheet annually and a considerable amount of electric power, to reduce gas consumption for cutting and heating, and to save on cutting tools.

Evaluation of Infrared Heating in a Michigan Greenhouse

ABSTRACT INFRARED heating has been found to be a practical heating system for a 2790 m^ greenhouse in Michigan. It provided a 31 percent reduction in gas consumption and a 17 percent reduction in costs when compared to a gas boiler system. Uniform temperatures can be main-tained and high quality crops can be grown under the alternative infrared heating system
