Process for manufacturing hot plate in chemical industry

Abstract

The invention provides a technique for producing a hot-plate used by chemical industry and relates to a producing technique of chemical members. The processing method is characterized in that: circulation channels for heating steam is milled out on the parent material of the hot-plate by utilizing a milling cutter, the inlets and the outlets for heating steam are processed by utilizing an ordinary drilling machine to form complete steam circulating passages with the heating steam circulation channels in the plate; cover plates are utilized for making up open parts formed by milling the steam channels by the milling cutter and are combined with the parent material of the hot-plate; the borders where the parent material of the hot-plate and the cover plates are combined are welded so as to lead the channels in the plate to form a whole; the bulkheads of the milled heating steam circulation channels are provided with sealing gaskets; the distance between the channels are regulated, or the trend and the circulation circuit of the channels are regulated so as to ensure the uniformity of the temperature of the hot-plate structure. The invention has simple processing technique, low requirements on processing devices and is advantageous for popularization and convenient for maintenance and inspection in plants.

Description

technical field [0001] The invention relates to a manufacturing process of a chemical component, in particular to an improved process for the current manufacturing process of a hot plate. Background technique [0002] In the past, in the manufacture of hot plates for chemical heat exchange components, deep hole drilling was widely used to process large-area hot plates, which required high processing requirements, great difficulty, slow speed, and low efficiency. Equipment can only be processed, which is not conducive to the trend of modern rapid development, and the steam circulation system is not conducive to the uniformity of the temperature of the hot plate. The damage to the processing equipment during the processing is relatively large. Contents of the invention [0003] The purpose of the present invention is to provide an improved process for the current hot plate processing and manufacturing process. This process uses a milling cutter to mill out a heating circula...
