PLANT REQUIREMENTS FOR MANUFACTURE OF PORCELAIN ENAMELWARE

The technical aids branch of the International Cooperation Administration has developed guidelines for the production of porcelain enamelware, which are outlined in this document. The document emphasizes the importance of selecting the right raw materials, including the type of steel used for the "black shapes" or "black plates." The steel should be of a specific type, such as sheet steel, and should be free from impurities and defects. The document also highlights the need for careful cleaning and pickling of the steel before it is used in the production process. The production process involves several stages, including cutting, grinding, and polishing of the steel. The steel is then coated with a layer of enamel, which is made from a mixture of silica, alumina, and other minerals. The enamel is applied using a dipping process, and the coated steel is then fired in a kiln at high temperatures to melt and set the enamel. The document also discusses the importance of controlling the temperature and atmosphere during the firing process to ensure that the enamel is properly set and that the steel is not damaged. The document provides guidelines for the selection of the right type of enamel and the application of the enamel to the steel. In addition to the production process, the document also discusses the importance of quality control and inspection of the finished products. The document provides guidelines for the inspection of the products for defects and imperfections, and for the storage and handling of the products to prevent damage. The document also discusses the use of certain additives, such as silica, alumina, and other minerals, to improve the properties of the enamel and to enhance the appearance of the finished products. The document provides guidelines for the selection and application of these additives, and for the control of the temperature and atmosphere during the firing process. The document concludes by emphasizing the importance of careful planning and control of the production process to ensure the production of high-quality porcelain enamelware. The document provides guidelines for the selection of the right raw materials, the production process, and the quality control and inspection of the finished products. The document provides detailed information on the production process, including the cutting, grinding, and polishing of the steel, the application of the enamel, and the firing process.
