0.5-1 ton intermediate frequency furnace wet construction process

Abstract

The invention relates to a 0.5-1 ton intermediate frequency furnace building technology based on a wet method. The technology is characterized by comprising the following steps: a. cutting asbestos cloth according to the dimension of an electric furnace, and preparing a quartz sand mixing material according to the size of an intermediate frequency furnace; b. distributing the asbestos cloth which is cut in advance from top to bottom on a coil in a furnace-body-type cavity to be built; c. knotting for the bottom of the furnace; d. mounting a steel pot model; e. knotting for a furnace wall; f. knotting for the top of the furnace; g. knotting for a water outlet groove; and h. drying the furnace. According to the invention, the flow is reasonable, the operation is simple, and the production cost is low; after the quarts sand is stirred and mixed by use of an appropriate amount of water, the adhesivity is stronger, feeding and knotting are convenient and simple, the furnace liner has high degree of compacting, the service life of the furnace is improved, the service life of a 1 ton intermediate frequency furnace is prolonged to 15-25 days, the service life of a 0.5 ton intermediate frequency furnace is prolonged to 80-90 days, the steel pot can also be extracted in the process of drying the furnace and can be used again, and the economic benefit is obvious.

Description

technical field [0001] The invention relates to a 0.5-1 ton intermediate frequency furnace wet method furnace building process, which belongs to the technical field of cast iron piston ring casting. Background technique [0002] The original intermediate frequency furnace lining was built using quartz sand dry-mixing technology. The compactness of the furnace lining is poor, and the service life of the furnace is short. The average service life of a 1-ton intermediate-frequency furnace is 10-12 days, and the average service life of a 0.5-ton intermediate frequency furnace is 50-60 days. And when the furnace is baked, the steel pot cannot be pulled out, and needs to be melted with the furnace, and the cost is relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a 0.5-1 ton intermediate frequency furnace wet furnace construction process, which is conducive to improving the service life of the furnace body and reducing manufac...
