Problems solved by technology

[0002] The 7.63m coke oven is designed by the world-renowned coking process design company Uhde, Germany, all of which are designed according to German technology standards. The equipment manufacturing process is relatively complicated and the technical standards are high.
The top cover of the water seal has a flat top structure, and the height of the lower straight section is far higher than the standard head. It does not belong to the standard elliptical head. It cannot be formed at one time by using the known head pressing technology. If it is segmented and then spliced Integral, will affect the airtightness of the contact surface; and there are some unscientific and unreasonable places in foreign traditional technology, the production process is complicated and the production cost is high
[0003] Therefore, there are above-mentioned inconveniences and problems in the known 7.63m coke oven riser water sealing cover manufacturing method

Abstract

A 7.63 coke oven ascension pipe water sealing cover manufacturing method is characterized by comprising the following steps of A. manufacturing a water sealing cover top cover, B. manufacturing a water sealing cover base, C. manufacturing a steel rotary handle and D. assembling a water sealing cover, wherein the step A comprises a first step of manufacturing a mould special for the water sealing cover top cover and a second step of manufacturing the water sealing cover top cover in a pressing mode. The 7.63m coke oven ascension pipe water sealing cover manufacturing method has the advantages of being reasonable in manufacturing step design and simple in operation, the water sealing cover can be flexibly opened, sealing performance is good, and manufacturing cost is lowered.

Description

technical field [0001] The invention relates to a method for manufacturing a water seal, in particular to a method for manufacturing a water seal for a 7.63m coke oven riser. Background technique [0002] The 7.63m coke oven is designed by the world-renowned coking process design company Germany Uhde Company, all of which are designed according to German technology standards. The equipment manufacturing process is relatively complicated and the technical standards are high. The 7.63m coke oven riser consists of a water seal cover, a lower riser and an upper riser. The water seal cover can effectively prevent the escape of raw gas, and also provides convenience for maintenance work; the stainless steel top cover and its base of the water seal cover are the key components of the entire water seal cover, and its processing quality determines the water seal cover. Whether it can effectively prevent the escape of raw gas. The top cover of the water seal has a flat top structure...
