Problems solved by technology

Due to the corrosion of zinc and iron, the service life of cast iron pots is very short, about 20 days; and the quality of galvanizing will be affected after iron is melted into zinc, and the zinc consumption per unit product is also high; at the same time, the production of furnace gas Air pollution is relatively serious, causing environmental pollution, so there is an urgent need for a galvanizing furnace that can resist zinc liquid corrosion to replace the existing cast iron pan galvanizing furnace

Abstract

The invention provides a ceramic crucible for a galvanizing furnace and a production method thereof, wherein the ceramic crucible is prepared by the following materials by weight percent: 75%-78% of silicon carbide sand, 12%-16% of metallic silicon powder, 0.7%-1% of clay, 3%-5% of micro powder binding agent, 0.3%-0.4% of rare metal additive, and 5%-6% of glue. According to the ceramic crucible for the galvanizing furnace, the micro powder binding agent and the additives such as rare metal (yttrium) are added into materials to improve the formability of the raw materials of a ceramic green body, and the property of the silicon nitride combined the silicon carbide material is modified to improve the thermal shock resistance and the using property of the material, so that the material has the advantages of high temperature resistance, good molten zinc corrosion resistance, long service life and the like; and the crucible is integrally formed for one time through pressing by a vibrating press, so that the uniformity of the product density is ensured and the thermal shock resistance of the product is improved.

Description

technical field [0001] The invention provides a galvanizing furnace, in particular a ceramic crucible for a galvanizing furnace and a manufacturing method thereof. Background technique [0002] At present, the small galvanizing furnaces on the market mainly use the generator gas to heat the cast iron pot to process the galvanized parts. Due to the corrosion of zinc and iron, the service life of cast iron pots is very short, about 20 days; and the quality of galvanizing will be affected after iron is melted into zinc, and the zinc consumption per unit product is also high; at the same time, the production of furnace gas Air pollution is relatively serious, causing environmental pollution, so there is an urgent need for a galvanizing furnace that can resist the corrosion of zinc liquid to replace the existing cast iron pan galvanizing furnace. Contents of the invention [0003] The purpose of the present invention is to provide a ceramic crucible for galvanizing furnace and...
