Novel ceramic zinc pot and electrical heating arrangement method

Abstract

The invention discloses a novel ceramic zinc pot which comprises a zinc pot body consisting of refractory ceramic bricks, wherein a plurality of placing positions which are perpendicular to the bottom surface of the zinc pot body are arranged on the side wall of the zinc pot body and extend sequentially along the length of the side wall, and heating units are arranged on the placing positions; the heating units comprise quartz glass tubes fixed inside the placing positions; and electrical heating wires are arranged in the quartz glass tubes, and sheaths are arranged outside the quartz glass tubes. Due to the adoption of a new electrical heating arrangement mode, the size of the zinc pot can meet the requirement of modern galvanization, the problem of plating large-scale workpieces is solved, and the invention has the advantages that the novel ceramic zinc pot is easy to operate, safe in use, and saves energy and zinc. Simultaneously, the invention also discloses an electrical heating arrangement method for the novel ceramic zinc pot.

Description

technical field [0001] The invention relates to the technical field of galvanizing, in particular to a novel ceramic zinc pot, and also to an electric heating arrangement method. Background technique [0002] The external heating iron-zinc pot has a history of more than two hundred years. It is the most primitive zinc pot. It is only suitable for galvanizing below 460°C, and it is not suitable for galvanizing aluminum-zinc alloys and high-temperature galvanizing. At present, most enterprises in the country use low-carbon and low-silicon steel for galvanizing pots, and low-temperature (below 460°C) galvanizing. The service life of galvanizing pots is generally 3 to 7 years. Galvanized at 560-580°C, the zinc pot welded to the 40mm thick steel plate will be corroded and perforated in less than half a month, and the loss of zinc will be large. Use a 100mm thick cast iron zinc pot and galvanize malleable cast iron at 600°C , It will be penetrated by zinc solution in about half a...

AI Technical Summary

Problems solved by technology

[0005] In the 1980s, many scientific and technological workers in our country started the research on immersion heating zinc pots, and many of them also made some achievements. The ceramic zinc pots developed were used for galvanizing steel wires or bolts, saving 50% zinc. %, the energy saving is at least 50%, but the disadvantages of conventional zinc pots are: the zinc pot is small, the longest is no more than 7 meters, the range of plating parts is greatly limited, the problem of high temperature insulation is not easy to solve, and electric heating breakdown , frequent short circuit damage
